Methodology for Setting the Basic Interconnection Price or Charge for Small-Scale Self-Consumption Generators with the SENMetodología de fijación del precio o cargo básico por interconexión de generadores a pequeña escala para autoconsumo con el SEN

the materials, equipment, and construction costs necessary for the installation of the generator are borne by the interested party", so this request falls outside the scope of the methodology.

2.2 "These costs should be part of the basic tariff for all users (not only solar). It is a national necessity. Furthermore, these costs distributed among 4 million people represent less than 1 colon per person"

the materials, equipment, and construction costs necessary for the installation of the generator are borne by the interested party", so this request falls outside the scope of the methodology.

3 Cooperativa de Electrificación Rural de San Carlos R.L. (COOPELESCA R.L.), legal identification number 3-004-045117, represented by Omar Miranda Murillo, general manager, identification number 501650019.

3.1 In point "d" of the Scope, an extraordinary setting is mentioned, but the procedure and conditions are not detailed.

The procedure will be the same as established in the methodology and will be used under the conditions established in article 30 of Law 7593, which provides, among other things, that the settings can be of an ordinary or extraordinary nature; the ordinary ones contemplate cost and investment factors, this in accordance with numeral 3 subsection b) of the cited Law. While extraordinary settings are "those that consider important variations in the economic environment, due to fortuitous event or force majeure and when the conditions of the automatic adjustment models are met. The Regulatory Authority will carry out, ex officio, said settings". Regarding this point, the clarification is made in subsection d of section 4.2, folio 08, file OT-253-2014.

3.2 It should be clarified if the information requirements (points a and b) refer to generators already connected. If so, must these update their legal standing with the MINAE concession?

Subsection a of section 5.1, folio 09 (OT-253-2014) refers to projections of new generators, while subsection b of the same section refers to generators already connected to the network (year after year).

Regarding the concession, it should be noted that article 1 of the Technical Standard for Planning, Operation, and Access to the National Electric System (POASEN), establishes regarding its scope of application "(.) Its application is mandatory, as applicable, for all subscribers or users at high voltage, electric power generation, transmission, and distribution companies, and subscribers or users at low and medium voltage with small-scale generation for self-consumption, that are established in the country or that may come to be established under a concession regime, in accordance with the corresponding laws".

On the other hand, article 3 on definitions establishes that "(.) Concession: It is the authorization granted by the State to operate, exploit, and provide the service of electric power generation, transmission, distribution, or commercialization.

Enabling title." In that sense, articles 5 and 9 of Law 7593, establish respectively, the first in subsection a) that for the case of electric power supply in the stages of generation, transmission, distribution, and commercialization, the authorization to provide said services will be granted by the Ministerio de Ambiente y Energía, and article 9 indicates that "To be a provider of public services, referred to in this law, the respective concession or permit from the public entity competent in the matter must be obtained, as provided in article 5 of this law.

Exempted from this obligation are public institutions and companies that, by legal mandate, provide any of these services. However, all providers will be subject to this law and its regulations (.)".

3.3 On information requirements, point d, it should be clarified which procedure it refers to.

It refers to the application of the current methodology, which is clarified in section 5.1 subsection d, folio 09, file OT-253-2014.

3.4 It should be clarified what includes the network adaptations for the connection of a microgenerator (less than 50 kVA).

The adaptations (and their costs) to the network for the connection of a microgenerator, when applicable, will be made in accordance with the provisions of articles 127 and 128 of the POASEN Standard. Said standard establishes that the first step for such consideration is to carry out a study.

The foregoing is indicated in folio 07: "... It should be noted that there are costs that are assumed by the small-scale generator in accordance with the technical requirements established in the POASEN standard, which are not included in the price or charge for interconnection that Aresep proposes to establish, since these correspond to specific requirements of the interested party and the adaptation of the distribution network necessary in a particular way in relation to the size of the small-scale generator and the conditions of the distribution network, in accordance with the provisions of articles 127 and 128 of the referred standard." 3.5 It should be clarified if it is a one-time charge.

In the electric system, interconnection costs by definition are understood as a charge that is made on a one-time basis.

3.6 Formula 1, it is considered that the subscripts are unnecessary and tend to confuse. It would be simpler to indicate that the first term corresponds to the sum of costs of all types of equipment. Furthermore, the tariff, in accordance with Law 7593, has a determined period.

The subscripts are necessary in each formula to indicate which parameter each variable refers to.

3.7 Three aspects should be considered: The transportation expenses of special equipment (vehicle, cranes, etc.) required for installation, the differences for lost time (travel) due to the fault of the interested party in distributed generation, because due to the lack of some technical detail the installation cannot be carried out, and differences in fixed costs such as engineers' salaries, for reasons of coverage density economies.

These costs are contemplated among the fixed costs of the company that are found in the access tariff that will be calculated with the "Methodology for setting the price or charge for access to the distribution networks of small-scale generators for self-consumption that join the National Electric System (SEN) with basis in the AR-NT-POASEN standard", processed in file OT-252-2014.

3.8 Formula 2, on t, according to Law 7593 such a period does not exist, so it should say that it is the period for which the estimates are made. By t is understood the period in which the tariff will be in force, as indicated by article 34 of Law 7593: "The tariffs and prices set by the Regulatory Authority shall govern from their publication in the official newspaper La Gaceta or from the moment indicated in the corresponding resolution and, in no case, may they have retroactive effect".

3.9 It is not clear how Aresep will determine the number and profile of the workers necessary to carry out the engineering study, inspection, and commissioning of the generator's interconnection.

To establish tariff methodologies, Aresep is governed by the legal framework stipulated by Law 7593, in this case article 31 is applied: "To set the tariffs and prices of public services, the Regulatory Authority will take into account the model productive structures for each public service, according to the development of knowledge, technology, the possibilities of the service, the activity in question, and the size of the providing companies." In relation to the previous article, article 16 of the General Law of Public Administration is also applied, which establishes: "1. In no case may acts contrary to univocal rules of science or technique, or to elementary principles of justice, logic, or convenience be issued." 3.10 It is considered that the entire development of formula 4 is unnecessary, since by law it must be so and, moreover, it is not even used in the general methodologies. On the other hand, this methodology does not consider the possibility of contracting the service with a third party.

Formula 4 is part of the calculation method of the interconnection charge. The methodology does not limit the possibility of subcontracting the service, but rather the cost that it will recognize to the company regardless of whether it executes it itself or contracts it.

3.11 It should be clarified that it is an interconnection charge and not a price.

For this case in particular, they are considered synonyms, given that in the title of the methodological proposal it was indicated that it is for setting the price or charge for interconnection.

4. A S I Power & Telemetry S.A., legal identification number 3-101-498793, represented by Mr. James Denis Ryan, bearer of passport number 442560436 (folio 54 to 60).

4.1 "(.) ARESEP is in charge of protecting consumers, in the area of small-scale private distributed generation, ARESEP seems to have abandoned the consumer, as well as the policies established by the government to promote renewable energy generation and carbon neutrality".

Among the objectives of Aresep established in article 4, subsection b of Law 7593, it is indicated: "To seek a balance between the needs of users and the interests of public service providers.", which is the daily work of the institution. Additionally, for the setting of tariffs and prices (article 31 of Law 7593), central elements are energy conservation and economic efficiency as defined in the National Development Plan.

4.2 "(.) the complexity, bureaucracy, and unnecessary associated costs that ARESEP has introduced stifle possible distributed generation projects. This will serve, undoubtedly, the interests of the distribution companies, but at the same time, it practically eliminates the viability of the smallest and most marginal economic projects".

Among the objectives of Aresep established in article 4, subsection b of Law 7593, it is indicated: "To seek a balance between the needs of users and the interests of public service providers.", which is the daily work of the institution.

4.3 "(.) ARESEP has truly unleashed a creative demon in the generation of bureaucracy by proposing that each distributor must provide detailed information on the use, generation, and cost information for each individual generator".

The compilation of information on small-scale generation is of utmost importance for Aresep, because it is required to know the access capacity of the different distribution circuits to distributed generation in accordance with the provisions of article 125 of the POASEN Standard, as well as for decision-making and to safeguard the interests of users.

Additionally, this information allows understanding the behavior of the market in general and not of a particular user, the benefits and costs of their incorporation into the electric system, the foregoing based on the powers granted by Law to Aresep -Articles 5, 6, 14. Subsection c) and 24 of Law 7593-.

In this regard, it should be noted that Article 24 of the cited Law provides for the obligation of regulated entities to supply Aresep with "reports, accounts, data, file copies and any other electronic or written medium where financial, accounting, economic, statistical and technical information related to the provision of the public service they offer is stored" and the Regulatory Authority shall have the power to "inspect and record the legal and accounting books, vouchers, reports, equipment and facilities of the providers." 4.4"(.) ARESEP is requesting details (.) of the consumption and production data of Distributed Generation generators. These data can be seen as a potential invasion of privacy, as they easily reveal the lifestyle of a homeowner. (.) ARESEP does not collect or store this type of information (.) about any other class of customers of any other public service it regulates. (.) However, for DG, they will know name, address, location and hour-by-hour and day-by-day, the amount of electricity consumed. (.) I believe this VERY SENSITIVE (sic) information is not necessary, as it will not be used properly and, most importantly, it will not be protected properly." The collection of information on small-scale generation is of utmost importance to Aresep, because it is required to know the access capacity of the different distribution circuits to distributed generation in accordance with the provisions of Article 125 of the POASEN Standard, as well as for decision-making and to safeguard the interests of the users.

Additionally, this information allows understanding the behavior of the market in general and not of a specific user, the benefits and costs of its incorporation into the electrical system, the foregoing based on the powers granted by Law to Aresep -Articles 5, 6, 14 subsection c) and 24 of Law 7593-. In that sense, it should be noted that Article 24 of the cited Law provides for the obligation of regulated entities to supply Aresep with "reports, accounts, data, file copies and any other electronic or written medium where financial, accounting, economic, statistical and technical information related to the provision of the public service they offer is stored" and the Regulatory Authority shall have the power to "inspect and record the legal and accounting books, vouchers, reports, equipment and facilities of the providers." In addition to the foregoing, the provisions of the Law for the Protection of Individuals Regarding the Processing of Their Personal Data -Law 8968- must be considered, which establishes in its Article 9 that sensitive data includes personal information revealing racial or ethnic origin, political opinions, religious, spiritual or philosophical convictions, as well as data relating to health, life and sexual orientation. Therefore, the information that will be requested by the regulatory body does not fall under the assumptions of sensitive data referred to in the cited law.

Likewise, said Law establishes as one of its principles the right to informational self-determination, which refers to the principle that "Every person has the right to informational self-determination, which encompasses the set of principles and guarantees relating to the legitimate processing of their personal data recognized in this section." This right has exceptions, which have been defined in Article 8, subsection e), which refers to the adequate provision of public services, which is a function of ARESEP, in accordance with Article 5 of Law 7593.

The information that Aresep makes available to the general public or to interested parties shall not be specific or individualized by customer or identifiable.

4.5"(.) The rest of the world is moving at a real pace towards renewable and solar generation in particles, but ARESEP's actions are totally retrograde and destructive for our nation's economy, our environment and our society's stated goals of carbon reduction and energy independence." Among the objectives of Aresep established in Article 4, subsection b of Law 7593, it states: "To seek a balance between the needs of users and the interests of public service providers," which is the daily work of the institution. Additionally, for the setting of rates and prices (Article 31 of Law 7593), energy conservation and economic efficiency as defined in the National Development Plan are central elements.

5. Compañía Nacional de Fuerza y Luz S.A., legal ID number 3-101-000046, represented by Mr. Víctor Solís Rodríguez, ID number 203330624, in his capacity as unlimited general proxy (folios 24 to 44).

5.1 A distinction must be made for the calculation between salaries for the public and private sectors, as there are differences between both mechanisms.

To establish tariff methodologies, Aresep is governed by the legal framework stipulated by Law 7593. In this case, Article 31 applies: "To set the rates and prices of public services, the Regulatory Authority shall take into account the model productive structures for each public service, according to the development of knowledge, technology, the possibilities of the service, the activity in question and the size of the providing companies." That is, a setting is carried out for the industry, where a tariff is set for all companies without making any type of differentiation.

5.2 The variable of the school salary (salario escolar) that by law applies to these institutions must be contemplated for Public Companies.

23907-H -published in La Gaceta 246 of December 27, 1994- establishes that the school salary (salario escolar) for public officials ________is "a percentage of the nominal salary of said servants, to be paid in a cumulative manner in the month of January of each year." In that sense, Executive Decree No. 38572-MTSS-MH -published in La Gaceta 157 on August 18, 2014- in its Article 7 establishes that: "The right of public workers to continue receiving the school salary (salario escolar) is ratified, under the legal conditions that have prevailed to date (8.19%)." On the other hand, the Law for the Promotion of School Salary in the Private Sector -Law No. 8682- in its numeral 2 provides that "The school salary (salario escolar) is a worker's savings and consists of a percentage calculated on the gross salary of each servant. The worker may opt for this right and for the corresponding calculation, the percentage chosen by the worker shall be applied, between four point sixteen percent (4.16%) and eight point thirty-three percent (8.33%) of the monthly salary." It follows from the foregoing that the school salary (salario escolar) is an amount already earned from the worker's own salary, which the State or the company, as the case may be, pays with funds from the worker's assets, and therefore does not constitute an expenditure that the employer must cover in addition to the salary (see in this regard resolution 04571-2005- of 4:24 p.m. on April 26, 2005, of the Constitutional Chamber).

5.3 For severance days, the current legislation for each company must be taken into account.

To establish tariff methodologies, Aresep is governed by the legal framework stipulated by Law 7593. In this case, Article 31 applies: "To set the rates and prices of public services, the Regulatory Authority shall take into account the model productive structures for each public service, according to the development of knowledge, technology, the possibilities of the service, the activity in question and the size of the providing companies." Furthermore, to perform the calculation of severance, the provisions of Articles 29 and 30 of the Labor Code shall apply. The former establishes the method of calculation and the latter the common rules applicable to severance, unless there is a special rule to the contrary.

5.4 It is requested to incorporate into the formula the following variables incurred by a distribution company and that are not considered in the previous formulas:

Travel expenses and transportation for technicians, safety equipment, protective elements, uniforms, measurement equipment required by technicians and their respective maintenance, costs of legal advice for the creation of interconnection contracts with generators and to follow up on complaints, queries and others that may arise in the implementation stage from a legal point of view, costs for sending additional reports to ARESEP and even to MINAE on this process, therefore these costs and costs of independent accounting records from the other business structures must also be considered.

These costs are contemplated among the fixed costs of the company that are in the access tariff (tarifa de acceso) which will be calculated with the "Methodology for setting the price or charge for access to the distribution networks for small-scale generators for self-consumption that are integrated into the National Electric System (SEN) based on the AR-NT-POASEN standard," processed in case file OT-252-2014.

6. Instituto Costarricense de Electricidad, legal ID number 4-000-042139, represented by Ms. María Gabriela Sánchez Rodríguez, ID number 107960417, in her capacity as special administrative proxy (folios 47 to 53).

6.1 It is requested to specify in subsection ii) the metering systems: the bidirectional common coupling point meter and the monthly energy produced meter.

The elements of the metering system are known to the distribution companies, namely the bidirectional common coupling point meter and the monthly energy produced meter.

6.2 It is requested to include that if, for reasons beyond the distribution company's control, the installations do not pass the final inspection and the same needs to be repeated and/or rescheduled, the interested party must cover the costs associated with the re-inspection(s), which must be expressly established within the methodology proposal.

This element is contemplated in the procedure for small-scale generation for self-consumption installations, which will be promulgated by the Regulatory Authority.

6.3 To include in the equipment costs the two metering systems: the bidirectional common coupling point meter and the monthly energy produced meter, since both are essential to verify the limit of production surpluses of up to 49% of the monthly energy produced.

Every service to be installed or in operation has a metering system whose costs are covered by the electricity company. The one paid by the subscriber or user with small-scale generation is the bidirectional metering system.

6.4 That the obligation of small-scale generators to build, on the boundary of their property, the necessary infrastructure for the installation of the metering system, without any impediment to taking monthly meter readings, be expressly regulated. In the same way, the obligation to relocate metering systems installed inside the property of the small-scale generator to its boundary must be established, to comply with taking readings without any impediment.

The foregoing point is regulated in numeral 5.2 of the current Technical Standard AR-NT-ACO "Installation and equipment of electrical connections (acometidas eléctricas)." 6.5 All costs associated with the construction and relocation of metering systems must be borne by the interested party.

The foregoing point is contemplated in Article 128 of the technical standard AR-NT-POASEN.

Folio 07 indicates: "... It should be noted that there are costs that are assumed by the small-scale generator in accordance with the technical requirements established in the POASEN standard, which are not included in the interconnection price or charge that Aresep proposes to establish, since these correspond to specific requirements of the interested party and to the adaptation of the distribution network necessary in particular in relation to the size of the small-scale generator and the conditions of the distribution network, in accordance with the provisions of Articles 127 and 128 of the aforementioned standard." 6.6 It is requested to clarify if nte corresponds to the number of equipment units contained in a quotation, invoice, and proforma invoice.

Indeed, the requested clarification proceeds and it is indicated in folio 11, formula 2, that "Regarding nte, it is understood that if a quotation, invoice, and/or proforma invoice contains different prices for several equipment units, each price is taken as one piece of data for that particular type of equipment." 6.7 It is requested to correct the section on first-time application to 5.1 instead of 4.1.

The position is accepted and the correction indicated in the first paragraph of section 5.4, folio 15, case file OT-253-2014, is made.

7. Junta Administrativa del Servicio Eléctrico Municipal de Cartago, represented by Mr. Juan Antonio Solano Ramírez, ID 106890115, official letter GG-848-2014 (folios 45 to 46).

7.1 The interconnection costs only detail the meters and connections (acometidas), but if the distribution company needs to implement any additional equipment, such as additional protection for the electrical network, it would not be contemplated within this interconnection cost.

The methodology is a procedure to calculate and set a basic interconnection tariff. Furthermore, the foregoing point is contemplated in Articles 127 and 128 of the technical standard AR-NT-POASEN.

Folio 07 indicates: "... It should be noted that there are costs that are assumed by the small-scale generator in accordance with the technical requirements established in the POASEN standard, which are not included in the interconnection price or charge that Aresep proposes to establish, since these correspond to specific requirements of the interested party and to the adaptation of the distribution network necessary in particular in relation to the size of the small-scale generator and the conditions of the distribution network, in accordance with the provisions of Articles 127 and 128 of the aforementioned standard." Indeed:

"Article 127. Network adaptations. The adaptations of the low-voltage distribution network necessary for the connection of a micro-generator, with a capacity of less than 50 kVA, to the national distribution network, shall be borne by the distribution company, unless it requires investments in the medium-voltage network.

In the event that network adaptations are required for the interconnection of mini-generators and micro-generators with a capacity greater than 50 kVA, the costs shall be borne by the interested party.

The materials, equipment, and construction costs necessary to go from the generator's facilities (micro or mini generator) to the distribution network shall be borne by the interested party, and for this purpose, the applicable standards and provisions issued by the Regulatory Authority must be complied with." 7.2 This methodology should mention the technical requirements and electrical diagrams of the equipment to be installed.

All technical requirements are requested prior to installation, as will be contemplated in the procedure for small-scale generation for self-consumption installations, which will be promulgated by the Regulatory Authority.

7.3 It must be clear how the hours for each type of worker are defined and also that, in the case of the fieldwork team, it may be two officials.

To establish tariff methodologies, Aresep is governed by the legal framework stipulated by Law 7593. In this case, Article 31 applies: "To set the rates and prices of public services, the Regulatory Authority shall take into account the model productive structures for each public service, according to the development of knowledge, technology, the possibilities of the service, the activity in question and the size of the providing companies." Supplementarily, Article 16 of the General Law of Public Administration applies, which establishes: "1. In no case may acts contrary to unequivocal rules of science or technique, or to elementary principles of justice, logic, or convenience be issued." Folio 12 indicates that: "The fixed costs of the service 𝐶𝐹𝑆𝑡 contemplate the engineering study, inspection, and commissioning of the interconnection of the small-scale generator with the distribution company's network. The calculation of these costs is established based on the wages and salaries, as well as the social charges and provisions of the personnel necessary to carry out said work." 7.4 Regarding the issue of social charges, although aguinaldo, vacations, and even notice, as well as the occupational hazard insurance policy, are indicated, there is also the issue of the school salary (salario escolar) which, although not a social charge, is part of the payroll cost.

23907-H -published in La Gaceta 246 of December 27, 1994- establishes that the school salary (salario escolar) for public officials is "a percentage of the nominal salary of said servants, to be paid in a cumulative manner in the month of January of each year." In that sense, Executive Decree No. 38572-MTSS-MH -published in La Gaceta 157 on August 18, 2014- in its Article 7 establishes that: "The right of public workers to continue receiving the school salary (salario escolar) is ratified, under the legal conditions that have prevailed to date (8.19%)." On the other hand, the Law for the Promotion of School Salary in the Private Sector -Law No. 8682- in its numeral 2 provides that "The school salary (salario escolar) is a worker's savings and consists of a percentage calculated on the gross salary of each servant. The worker may opt for this right and for the corresponding calculation, the percentage chosen by the worker shall be applied, between four point sixteen percent (4.16%) and eight point thirty-three percent (8.33%) of the monthly salary." It follows from the foregoing that the school salary (salario escolar) is an amount already earned from the worker's own salary, which the State or the company, as the case may be, pays with funds from the worker's assets, and therefore does not constitute an expenditure that the employer must cover in addition to the salary (see in this regard resolution 04571-2005- of 4:24 p.m. on April 26, 2005, of the Constitutional Chamber).

7.5 That a reasonable implementation period for this methodology be defined, as it should also include issues such as improvements to the metering, billing, and collection system.

The POASEN standard was published in La Gaceta No. 69 of April 8, 2014, indicating technical aspects that must be incorporated into the system for the purpose of carrying out small-scale generation.

8. Empresa de Servicios Públicos de Heredia S.A.: Represented by Mr. Allan Benavides Vílchez, identity card 401021032 (folios 61 to 73).

8.1 Point "d" of the Scope mentions an extraordinary setting (fijación de carácter extraordinario) but the procedure and conditions are not detailed.

The procedure will be the same as established in the methodology and will be used under the conditions established in Article 30 of Law 7593, which provides, among other things, that settings can be ordinary or extraordinary. The ordinary ones contemplate cost and investment factors, in accordance with numeral 3, subsection b) of the cited Law. Meanwhile, extraordinary settings (fijaciones extraordinarias) are "those that consider significant variations in the economic environment, due to unforeseen circumstances (caso fortuito) or force majeure, and when the conditions of the automatic adjustment models are met. The Regulatory Authority shall make such settings ex officio." On this point, a clarification is made in subsection d of section 4.2, folio 08, case file OT-253-2014.

8.2 It must be clarified whether the information requirements (points a and b) refer to generators already connected. If so, must these bring themselves into compliance with the MINAE concession?

Subsection a of section 5.1, folio 09 (OT-253-2014) refers to projections for new generators, while subsection b of the same section refers to generators already connected to the network (year after year).

Regarding the concession, it should be noted that Article 1 of the Technical Standard for Planning, Operation, and Access to the National Electric System (POASEN) establishes regarding its field of application "(.) Its application is mandatory, as applicable, for all high-voltage subscribers or users, electricity generation, transmission, and distribution companies, and low and medium-voltage subscribers or users with small-scale generation for self-consumption, that are established in the country or that may become established under a concession regime, in accordance with the corresponding laws." On the other hand, Article 3 on definitions establishes that "(.) Concession: It is the authorization granted by the State to operate, exploit, and provide the service of generation, transmission, distribution, or commercialization of electric energy.

Enabling title." In that sense, Articles 5 and 9 of Law 7593 establish, respectively: the former in subsection a), that for the supply of electric energy in the stages of generation, transmission, distribution, and commercialization, the authorization to provide said services shall be granted by the Ministry of Environment and Energy; and Section 9 indicates that "To be a provider of the public services referred to in this law, the respective concession or permit must be obtained from the competent public entity in the matter, as provided in Article 5 of this law.

Exempted from this obligation are public institutions and companies that, by legal mandate, provide any of these services. However, all providers shall be subject to this law and its regulations (.)." 8.3 Regarding information requirements, point d, it must be clarified which procedure it refers to.

It refers to the application of the current methodology, which is clarified in section 5.1, subsection d, folio 09, case file OT-253-2014.

8.4 It must be clarified what the network adaptations for the connection of a micro-generator (less than 50 kVA) include.

The network adaptations (and their costs) for the connection of a micro-generator, when applicable, shall be made in accordance with the provisions of Articles 127 and 128 of the POASEN Standard. Said standard establishes that the first step for such consideration is to conduct a study.

The foregoing is indicated in folio 07: "... It should be noted that there are costs that are assumed by the small-scale generator in accordance with the technical requirements established in the POASEN standard, which are not included in the interconnection price or charge that Aresep proposes to establish, since these correspond to specific requirements of the interested party and to the adaptation of the distribution network necessary in particular in relation to the size of the small-scale generator and the conditions of the distribution network, in accordance with the provisions of Articles 127 and 128 of the referenced standard." 8.5 It must be clarified whether it is a one-time charge.

In the electrical system, interconnection costs are, by definition, understood as a charge made on a one-time basis.

8.6 Formula 1, it is considered that the subscripts are not needed and rather tend to confuse. It would be simpler to indicate that the first term corresponds to the sum of the costs of all types of equipment. Furthermore, the tariff, in accordance with Law 7593, has a specific period.

The subscripts are necessary in each formula to indicate which parameter each variable refers to.

8.7 Three aspects must be considered: The transportation costs for special equipment (vehicle, cranes, etc.) required for installation, the differences due to lost time (trips) caused by the interested party in distributed generation, because the installation cannot be carried out due to the lack of a technical detail, and differences in fixed costs such as engineers' salaries, for reasons of economies of coverage density.

These costs are contemplated among the fixed costs of the company that are in the access tariff (tarifa de acceso) which will be calculated with the "Methodology for setting the price or charge for access to the distribution networks for small-scale generators for self-consumption that are integrated into the National Electric System (SEN) based on the AR-NT-POASEN standard," processed in OT-252-2014.

8.8 Formula 2, regarding t, in accordance with Law 7593, no such period exists, so it should state that it is the period for which the estimations are made. t is understood to mean the period during which the tariff will be in force, as indicated in Article 34 of Law 7593: "The rates and prices set by the Regulatory Authority shall come into effect upon their publication in the official newspaper La Gaceta or from the moment indicated in the corresponding resolution and, in no case, may they have retroactive effect." 8.9 It is not clear how Aresep will determine the quantity and profile of the workers necessary to carry out the engineering study, inspection, and commissioning of the generator's interconnection.

To establish tariff methodologies, Aresep is governed by the legal framework stipulated by Law 7593. In this case, Article 31 applies: "To set the rates and prices of public services, the Regulatory Authority shall take into account the model productive structures for each public service, according to the development of knowledge, technology, the possibilities of the service, the activity in question and the size of the providing companies." In relation to the preceding article, Article 16 of the General Law of Public Administration also applies, which establishes: "1. In no case may acts contrary to unequivocal rules of science or technique, or to elementary principles of justice, logic, or convenience be issued." 8.10 It is considered that the entire development of formula 4 is unnecessary, since by law it must be this way, and furthermore, it is not even used in the general methodologies. On the other hand, this methodology does not consider the possibility of contracting the service with a third party.

Formula 4 is part of the method for calculating the interconnection charge. The methodology does not limit the possibility of subcontracting the service, but rather the cost that will be recognized to the company regardless of whether it performs it or contracts it out.

8.11 It must be clarified that it is an interconnection charge (cargo de interconexión) and not a price (precio).

For this particular case, they are considered synonyms, given that the title of the methodological proposal indicated that it is for setting the price or charge for interconnection.

(...)"

II.That in accordance with the preceding resultandos and considerandos and in accordance with the merits of the proceedings, the appropriate action is: 1- To approve the "Methodology for setting the basic price or charge for interconnection of small-scale generators for self-consumption with the National Electric System (SEN) based on the POASEN standard", 2- The response to the opponents who participated in the public hearing held on December 15, 2014, is that indicated in Considerando I of the resolution agreed upon here, and to thank the valuable participation of all in this process.

III.That in ordinary session 08-2015 held on February 26, 2015, the Board of Directors of the Regulatory Authority for Public Services, based on the proposal of the Ad Hoc Commission of February 24, 2015, via official letter 02-CAIGD-2015, as well as official letter 152-DGAJR-2015 of February 24, 2015, agreed, among other things and with a firm character:

Based on the powers conferred in Law No. 7593 and its reforms, in the General Law of Public Administration No. 6227, in Executive Decree No. 29732-MP, which is the Regulations to Law No. 7593, and in the Internal Regulations for Organization and Functions of the Regulatory Authority for Public Services and its Deconcentrated Body.

THE BOARD OF DIRECTORS OF THE REGULATORY AUTHORITY FOR PUBLIC SERVICES

I.To approve the "Methodology for setting the basic price or charge for interconnection of small-scale generators for self-consumption with the National Electric System (SEN) based on the POASEN standard", presented according to the official letter issued by the Ad Hoc Commission on February 24, 2015, via official letter 02-CAIGD-2015, as detailed below:

"(...)

3. Legal framework The methodological proposal and its possible approval find legal support in the regulations cited below:

• a)Law No. 7593, Law of the Regulatory Authority for Public Services, establishes, in its Article 5, that ". In the public services defined in this article, the Regulatory Authority shall set prices and rates." The cited public services include, in subsection a) of the same article, the "Supply of electric energy in the stages of generation, transmission, distribution and commercialization." b) The current standard called "Planeamiento, Operación y Acceso del Sistema Eléctrico Nacional (AR-NT-POASEN)".
• c)The Board of Directors of the Public Services Regulatory Authority, pursuant to the provisions of Article 6, subsection 2), sub-subsection c) of the Internal Regulations of Organization and Functions of the Public Services Regulatory Authority and its deconcentrated body, is empowered to issue and modify the regulatory methodologies to be applied in the various markets. Said regulation was published in Supplement 13 to La Gaceta No. 69, of April 8, 2009, and its amendments.

In accordance with the foregoing, it is clear that the Board of Directors of the Regulatory Authority is competent to issue and modify the tariff methodologies for regulated public services, including electricity generation, for which it must follow the public hearing procedure, as provided in Article 36 of Ley 7593. The cited legal framework provides the basis that empowers ARESEP to establish and/or modify the regulatory methodologies that are the subject of this report.

4. Objective and Scope 4.1. Objective The objectives of this methodology are:

• a)To define the tariff-setting procedure to establish the basic price or charge for interconnection of small-scale generators for self-consumption to the National Electric System (SEN), at the distribution stage, based on the POASEN standard.
• b)To comply with the provisions of the POASEN standard.
• c)To have tariff calculation procedures that are clear and verifiable.
• d)To safeguard the interests of the final consumer through compliance with the cost-of-service principle.
• e)To ensure the financial equilibrium of the regulated public service provider.

4.2. Scope The scope of this methodology is delimited as follows:

• a)It applies throughout the national territory.
• b)It applies to all electricity distribution companies.
• c)It applies to all small-scale generators.
• d)It applies to both ordinary and extraordinary rate settings, when applicable, as stipulated in Ley 7593.

5. Methodology 5.1. Information Requirements Qualified electric power distribution companies must submit the following information to the Public Services Regulatory Authority, no later than January 15 of each year, in printed and fully editable electronic format with the corresponding formulas and links:

a. Projections of new small-scale generators to be connected to the distribution network, according to their market segment or their concession area, as established in the Company's Business Plan or the corresponding operational plans, for at least a period of the following twelve months.

b. Number of small-scale generators connected to the network according to their market segment or their concession area, during the year.

c. Status of the remaining capacity of their distribution networks for the interconnection and operation of small-scale generators for self-consumption, in accordance with the provisions of Article 125 of the AR-NT-POASEN standard.

d. Invoices and pro-forma invoices detailing the costs of the required metering system (meter, meter base, and connection accessories), whose validity is at least one business day after the start of the procedure (of applying the current methodology) and, furthermore, these invoices must not have been issued more than two calendar months prior. In the event that the invoice indicates that prices vary without prior notice, they must not have been issued more than two calendar months prior.

e. Regardless of the detail of the prices of each and every part included in the metering system, the distribution companies shall certify a total price for all the basic interconnection equipment.

If any of the days mentioned in the previous points is not a business day, it shall be understood as referring to the immediately preceding business day.

5.2. Formula for the Basic Price or Charge for Interconnection For the purposes of establishing the interconnection costs of a small-scale generator with the distribution network, the costs associated with the following shall be considered:

• i)The technical feasibility study of the interconnection point (Article 126 of the AR-NT-POASEN standard) and preliminary inspection.
• ii)Equipment for the electrical connection and the metering system.
• iii)Final inspection and commissioning.
• iv)Additionally, the interconnection costs include the costs associated with ensuring that said connection meets the technical requirements established in the POASEN standard.

Thus, the interconnection cost in colones for a small-scale generator for self-consumption is defined as follows:

Where:

t = Period during which the basic interconnection charge or price will be in effect.

= Interconnection cost in colones during period t, by type of equipment te.

= Equipment costs in colones by type of equipment te during period t (see Formula 2).

= Fixed service costs in colones during period t (see Formula 3).

te = Type of equipment (Single-phase without recording of quality parameters, three-phase without recording of quality parameters, and three-phase with recording of quality parameters).

The basic interconnection cost will be the cost in colones that the electric power distribution company will charge the interested party for interconnecting and operating a generator (leaving it operating or in service) or small-scale generation installation associated with an electrical service in accordance with the technical standard AR-NT-POASEN and others promulgated by the Regulatory Authority.

The equipment costs in colones 𝐶𝐹𝐸 𝑡,𝑡𝑒 will be those of the metering system that meet the technical requirements established in the current regulations and the technical requirements that are part of the interconnection and commissioning procedure approved by the Regulatory Authority. The following equipment costs are considered:

• i)That of the bidirectional meter or counter, according to the characteristics established in the technical standard AR-NT-POASEN, the technical requirements that form part of the approved interconnection and commissioning procedure, and the current AR-NT-CON standard "Uso, funcionamiento y control de contadores eléctricos".
• ii)The base for installing the counter and the instrument transformers when necessary.
• iii)The service entrance conductors and connection accessories, when necessary.

There shall be three different equipment cost values (and consequently, three different interconnection costs), depending on the type of service, as follows:

1. For single-phase residential, general, and industrial services, the basic cost must be that of a simple bidirectional single-phase meter (without quality recording).

2. For three-phase, general, and industrial services with generators or generation installations less than or equal to 250kW, the three-phase meter shall be a simple bidirectional meter (without quality recording).

3. For three-phase, general, and industrial services with generators or generation installations exceeding 250kW, the three-phase meter shall be bidirectional with recording of quality parameters.

The cost of this equipment must be uniform for all companies and shall correspond to the average cost in colones of the quotes, invoices, and pro-forma invoices for each of the three types of equipment indicated above.

For the purposes of having information on the costs of this equipment, the Energy Authority (IE) will request that electricity distribution companies provide invoices and pro-forma invoices that allow determining their cost. Also, the IE will request said price information from the direct suppliers of these systems in the Costa Rican and international markets, taking into consideration that for the latter, the cost must include the availability of the system in the national territory. It may also have information from the Ministry of Finance on the costs of this equipment, including import, customs clearance, and other costs, if warranted. However, what is of interest is the final price of the complete metering system that would be installed in the electrical service with small-scale generation for self-consumption.

In order to obtain a single equipment cost for period t according to the type of service, the following procedure will be followed:

 The equipment must meet the technical requirements established in the POASEN standard, the technical requirements that form part of the approved interconnection and commissioning procedure, and the current AR-NT-CON standard "Uso, funcionamiento y control de contadores eléctricos".

 The information requested must comply with the validity period established in the information requirements section.

 Prices will be indicated in Costa Rican colones. In the event that said prices are in United States dollars, for conversion purposes to colones, the sell exchange rate for the non-banking public sector (CRC/USD), published by the Central Bank of Costa Rica, on the date of the corresponding invoice will be used.

Said calculation will be made by the distribution company when it supplies the information, or by the IE when it is the one that has requested the information directly from the suppliers.

If the initial prices are in a currency other than the United States dollar, it will be the responsibility of the information supplier to Aresep to request it in United States dollars when applicable and subsequently, to perform the proper currency conversion to colones.

 If there are several invoices from the same equipment supplier for one or several electric power distribution companies and for one or several parts of the metering system, with identical characteristics but different prices and with the required validity, the highest-priced ones will not be taken into account.

 When the price of one or several parts of the metering system includes discounts with the required validity, this must be accounted for in the total price of the equipment.

If the discount modality is per quantity of equipment with a sales option and meets the required validity, this must be accounted for in the total price of the equipment.

 In accordance with Ley 7593, the information submitted by any natural or legal person with standing will be taken into account, provided it is a total price for all the interconnection equipment, which must be duly substantiated.

This information will comply with what is indicated in the preceding paragraphs regarding the currency in which it will be expressed or performing the respective conversion.

 The information to be used in the calculation will be that available on the date of the public hearing for the tariff setting based on this methodology.

Once the information (supplied by the distribution companies and interested parties with standing, as well as that gathered by the IE) on the total equipment price has been compiled and refined, the price or charge used to calculate the interconnection cost will be the average of the total equipment prices. As follows:

Where:

t = Period during which the basic interconnection charge or price will be in effect.

= Fixed equipment costs in colones by type of equipment te during period t.

= Total equipment price in colones by type of equipment te according to price indicator s.

= Number of quotes, invoices, and pro-forma invoices by type of equipment te.

s = Indicator of information prices (refined and compiled) on the total interconnection equipment price in colones, available by Aresep, at the time of the public hearing.

te = Type of equipment (Single-phase without quality recording, three-phase without recording, and three-phase with recording of quality parameters).

Regarding nte, it is understood that if a quote, invoice, and/or pro-forma invoice contains different prices for several units of equipment, each price is taken as one data point for that particular type of equipment.

The fixed service costs include the engineering study, inspection, and commissioning of the interconnection of the small-scale generator with the distribution company's network. The calculation of these costs is established based on wages and salaries, as well as the social charges and provisions for the personnel necessary to perform said work.

The necessary personnel time is estimated as follows:

 The salary used will be that decreed by the Ministry of Labor and Social Security (MTSS) in force at the time of the public hearing for each of the occupations and daily shift times indicated in Table 1. The minimum wages per ordinary workday for the private sector are used, as detailed below:

Table 1. Type of worker according to occupation Minimum Wage Category Source: Minimum Wage Decrees MTSS. (1) Corresponds to the acronyms of the categories according to the current Minimum Wage Decree.

 The minimum social charges, provisions, and the costs of the workers' compensation insurance policy are those contemplated in Table 2 below:

Table 2. Social charges according to current legislation The percentages indicated in Table 2 may vary if the legislation is modified, and the values in effect on the day of the public hearing for the application of this model will be used. The workers' compensation factor (PTR) corresponds to the rate established for this type of worker in the Electricity, Gas, and Water Supply Section within the Electrical Energy Generation, Collection, and Distribution Division, according to the International Standard Industrial Classification (ISIC) used in the rate manual of the Instituto Nacional de Seguros (INS), in force on the day of the public hearing for the application of this model, determined on the personnel cost of the specialized worker and for a university bachelor's degree professional (Bach).

The fixed service cost in colones 𝐶𝐹𝑆𝑡 during period t will be the sum of the two total cost items for the workers (TES, Bach) that include wages and salaries, as well as social charges and the costs of the workers' compensation insurance policy, as detailed below:

Where:

t = Period during which the basic interconnection charge or price will be in effect.

= Fixed service costs in colones during period t.

= Total wage and salary cost in colones of the Specialized Worker (see Formula 4).

= Total wage and salary cost in colones of a University Bachelor (see Formula 6).

According to the current minimum wage decree, for the specialized worker category (TES), the minimum wage is defined per ordinary workday (8 hours). In order to obtain the total wage and salary cost of said item for the estimated time required for interconnection, the minimum wage amount per ordinary workday for this TES will be divided by 2. This is because the salary is presented for an 8-hour workday and 4 hours are required; therefore, the required salary is the daily salary divided by 2. To this cost in colones are added the minimum social charges and provisions described in Table 2 (which are currently 38.67%) plus the current factor for the workers' compensation insurance policy (PTR). This cost in colones is obtained as follows:

Where:

= Total wage and salary cost in colones of the Specialized Worker (TES) for interconnection (4 hours).

= Minimum wage for an ordinary workday of a specialized worker.

FCS = Factor for minimum social charges and provisions.

= Factor for the workers' compensation insurance policy for a specialized worker.

= Amount in colones of severance pay applicable to the specialized worker TES (see formula 5).

The applicable severance pay amount is calculated as follows:

Where:

= Amount in colones of severance pay applicable by worker type d.

= Days of severance pay legally recognized according to Article 29 of the current Labor Code, assuming that one workday is one interconnection of a small-scale generator.

= Minimum wage for an ordinary daily workday, in colones, according to worker type d (Specialized Worker or University Bachelor).

= Total number of small-scale generators interconnected in the last 12 months.

D= Type of worker (Specialized Worker or University Bachelor).

In the case of the University Bachelor (Bach), the minimum wage is established monthly, according to the MTSS decree and for which the ordinary daily workday must not exceed 8 hours per day. This total wage and salary cost in colones is the salary amount established in the mentioned decree for the monthly workday and is divided by 30 (proportional rest days) to obtain a daily salary. In this way, the total wage cost in colones for this item is obtained, to which is added the amount in social charges (which is a percentage of the salary, currently 38.67%) plus the amount in colones of the Workers' Compensation Insurance Policy (which is a percentage of the salary). This cost in colones is obtained as follows:

Where:

= Total wage and salary cost of a university bachelor for interconnection (8 hours).

= Minimum wage for one work hour of a university bachelor.

30 = 30 working days per month (proportional rest days).

FCS = Factor for minimum social charges and provisions.

= Factor for the workers' compensation insurance policy for a university bachelor.

= Amount in colones of severance pay applicable to the university bachelor (see formula 5).

In summary, the fixed cost in colones per service is obtained by calculating the cost of the number of man-hours required to perform the interconnection (engineering study, inspection, and commissioning of the interconnection service between the small-scale generator and the electric power distribution company).

5.3. Price Adjustments and Reviews The interconnection charge or price will be reviewed at least once a year, through an ordinary setting procedure, in accordance with the provisions of Ley 7593. To this end, all costs defined in the calculation of this price or charge will be reviewed—and when applicable, updated—according to the procedure described in this methodology.

The procedure will begin on the first business day of February of each year, that is, on this day the tariff file must be opened.

5.4. First-Time Application Once this methodology is approved and published in La Gaceta, the electric power distribution companies will have a maximum of 30 business days to supply the information required in point 5.1 of this proposed methodology. Otherwise, the Regulatory Authority will apply the provisions of Article 38 of Ley 7593.

It is not omitted to indicate that in order to have more complete information and in accordance with the provisions of this proposed methodology, the IE will proceed accordingly to gather the pertinent information.

Once the 30 business days in which the electricity distribution companies must supply the information have elapsed, within a maximum period of the following 15 days, the IE will open the corresponding tariff file.

Regarding the severance pay amount for the first application, the figure of 90 interconnections will be taken as the number of interconnected small-scale generators, this figure constituting an estimate of the number of continuous days worked (minimum established in Article 29 of the Labor Code).

II.To consider as a response to the opponents who participated in the public hearing held on December 15, 2014, what is stated in Considerando I of the resolution agreed upon here, and to thank the valuable participation of all in this process.

In compliance with the provisions of Article 245 of the General Law of Public Administration, the ordinary motion for reversal or reconsideration may be filed against this resolution, which must be filed within three days counted from the day following notification, and the extraordinary motion for review, which must be filed within the deadlines indicated in Article 354 of the cited law. Both motions must be filed before the Board of Directors of the Public Services Regulatory Authority, which is responsible for resolving them.

Effective as of its publication in the official newspaper La Gaceta.

Los materiales, equipos y los costos de construcción necesarios para llegar de las instalaciones del generador (micro o mini generador), hasta la red de distribución, correrán a cargo del interesado, debiendo para ello cumplirse, en lo aplicable, con las normas y disposiciones emitidas por la Autoridad Reguladora." 7.2 Esta metodología debería mencionar los requerimientos técnicos y diagramas eléctricos de los equipos a instalar.

Todos los requisitos técnicos se solicitan previo a la instalación, tal y como estará contemplado en el procedimiento de instalaciones de generación a pequeña escala para autoconsumo, el cual será promulgado por la Autoridad Reguladora.

7.3 Debe quedar claro cómo se definen las horas de cada tipo de trabajador y además, que en el caso del equipo de trabajo de campo, pueden ser dos funcionarios.

Para establecer las metodologías tarifarias la Aresep se rige por el marco legal estipulado por la Ley 7593, en este caso se aplica el artículo 31: "Para fijar las tarifas y los precios de los servicios públicos, la Autoridad Reguladora tomará en cuenta las estructuras productivas modelo para cada servicio público, según el desarrollo del conocimiento, la tecnología, las posibilidades del servicio, laactividad de que se trate y el tamaño de las empresas prestadoras.".

Supletoriamente, se aplica el artículo 16 de la Ley General de la Administración Pública establece: "1. En ningún caso podrán dictarse actos contrarios a reglas unívocas de la ciencia o de la técnica, o a principios elementales de justicia, lógica o conveniencia.".

Se indica en el folio 12 que: "Los costos fijos del servicio 𝐶𝐹𝑆𝑡, contemplan el estudio de ingeniería, inspección y puesta en servicio de la interconexión del generador a pequeña escala con la red de la empresa distribuidora. El cálculo estos costos se establecen en función de los sueldos y salarios, así como las cargas sociales y provisiones del personal necesario para realizar dicha labor." 7.4 Dentro del tema de cargas sociales, aunque se indica aguinaldo, vacaciones y hasta preaviso, así como la póliza de riesgos de trabajo, también está el tema de salario escolar que aunque no es carga social, es parte del costo de la planilla.

El artículo 1 del Decreto Ejecutivo N° 23907-H -publicado en La Gaceta 246 del 27 de diciembre de 1994 - establece que el salario escolar para los funcionarios públicos es "un porcentaje del salario nominal de dichos servidores, para que sea pagado en forma acumulativa en el mes de enero de cada año". En ese sentido, el Decreto Ejecutivo Nº 38572-MTSS-MH -publicado en La Gaceta 157 el 18 de agosto de 2014- en su artículo 7º establece que: "Se ratifica el derecho de los trabajadores y trabajadoras públicas, a continuar percibiendo el salario escolar, en las condiciones legales que hasta la fecha han prevalecido (8.19%)".

Por otra parte, la Ley de Promoción del Salario Escolar en el Sector Privado -Ley N°8682- en su numeral 2 dispone que "El salario escolar es un ahorro del trabajador y consiste en un porcentaje calculado sobre el salario bruto de cada servidor. El trabajador podrá optar por este derecho y para el cálculo correspondiente se aplicará el porcentaje que la persona trabajadora escoja, entre un cuatro coma dieciséis por ciento (4,16%) y un ocho coma treinta y tres por ciento (8,33%) del salario de cada mes".

De lo anterior se desprende que el salario escolar es un monto ya devengado del propio salario del trabajador, el cual paga el Estado o la empresa según sea el caso, con fondos del patrimonio del trabajador, por lo que no constituye una erogación que debe cubrir el patrono en forma adicional al salario (ver en este sentido la resolución 04571-2005- de las 16:24 horas del 26 de abril de 2005 de la Sala Constitucional).

7.5 Que se defina un periodo razonable de implementación de esta metodología, ya que también debería incluir temas como mejoras al sistema de lectura, facturación y recaudación.

La norma POASEN fue publicada en La Gaceta No. 69 del 8 de abril de 2014, indicando aspectos técnicos que se deben incorporar al sistema a efectos de llevar a cabo la generación a pequeña escala.

8. Empresa de Servicios Públicos de Heredia S.A.: Representada por el señor Allan Benavides Vílchez, cédula de identidad 401021032 (folios 61 al 73).

8.1 En el punto "d" del Alcance se menciona una fijación de carácter extraordinario pero no se detalla el procedimiento y las condiciones.

El procedimiento será el mismo establecido en la metodología y se utilizará en las condiciones establecidas en el artículo 30 de la Ley 7593, el cual dispone entre otras cosas, que las fijaciones pueden ser de carácter ordinario o extraordinario, las ordinarias contemplan factores de costo e inversión, esto de conformidad con el numeral 3 inciso b) de la Ley citada. Mientras que las fijaciones extraordinarias son".aquellas que consideren variaciones importantes en el entorno económico, por caso fortuito o fuerza mayor y cuando se cumplan las condiciones de los modelos automáticos de ajuste. La Autoridad Reguladora realizará, de oficio, dichas fijaciones". En cuanto a este punto, se hace la aclaración en el inciso d de la sección 4.2, folio 08, expediente OT-253-2014.

8.2 Se debe aclarar si los requerimientos de información (punto a y b) se refiere a los generadores ya conectados. Si es así ¿Estos deben ponerse a derecho con la concesión del MINAE?

El inciso a de la sección 5.1, folio 09 (OT-253-2014) se refiere a proyecciones de nuevos generadores, mientras que el inciso b de la misma sección se refiere a los generadores ya conectados a la red (año con año).

En cuanto a la concesión, cabe indicar que al artículo 1 de la Norma Técnica de Planeación, Operación y Acceso, al Sistema Eléctrico Nacional (POASEN), establece en cuanto a su campo de aplicación "(.) Su aplicación es de obligatoriedad, en lo que les corresponda, para todos los abonados o usuarios en alta tensión, empresas de generación, transmisión y distribución de energía eléctrica, y abonados o usuarios en baja y media tensión con generación a pequeña escala para autoconsumo, que se encuentren establecidos en el país o que llegasen a establecerse bajo régimen de concesión, de conformidad con las leyes correspondientes".

Por otra parte el artículo 3 sobre la definiciones establece que "(.) Concesión: Es la autorización otorgada por el Estado para operar, explotar y prestar el servicio de generación, transmisión, distribución o comercialización de energía eléctrica.

En ese sentido, los artículos 5 y 9 de la Ley 7593, establecen respectivamente el primero en el inciso a) que el para el caso de suministro de energía eléctrica en las etapas de generación, transmisión, distribución y comercialización, la autorización para brindar dichos servicios será otorgada por el Ministerio de Ambiente y Energía y el 9 indica que "Para ser prestador de los servicios públicos, a que se refiere esta ley, deberá obtenerse la respectiva concesión o el permiso del ente público competente en la materia, según lo dispuesto en el artículo 5 de esta ley.

Se exceptúan de esta obligación las instituciones y empresas públicas que, por mandato legal, prestan cualquiera de estos servicios. Sin embargo, todos los prestadores estarán sometidos a esta ley y sus reglamentos (.)".

8.3 Sobre requerimientos de información, punto d, se debe aclarar a cuál procedimiento se refiere.

Se refiere a la aplicación de la actual metodología, lo cual se aclara en la sección 5.1 inciso d, folio 09, expediente OT-253-2014.

8.4. Se debe aclarar que incluye las adecuaciones a la red para la conexión de un microgenerador (menor de 50 kVA).

Las adecuaciones (y sus costos) a la red para la conexión de un microgenerador, cuando proceda, se harán de conformidad con lo establecido en los artículos 127 y 128 de la Norma POASEN como lo son los. Dicha norma establece que el primer paso para tal consideración es realizar un estudio.

Lo anterior se encuentra indicado en el folio 07: "... Debe notarse que hay costos que son asumidos por el generador a pequeña escala de acuerdo con los requerimientos técnicos establecidos en la norma POASEN, los cuales no están incluidos en el precio o cargo por interconexión que la Aresep propone establecer, ya que los mismos corresponde a requerimientos específicos del interesado y a la adecuación de la red de distribución necesario en forma particular en relación con el tamaño del generador a pequeña escala y a las condiciones de la red de distribución, de conformidad con lo establecido en los artículos 127 y 128 de la referida norma." 8.5 Se debe aclarar si se trata de un cobro por una única vez.

En el sistema eléctrico los costos de interconexión por definición se entienden como un cobro que se realiza por una única vez.

8.6 Fórmula 1, se considera que no hacen falta los subíndices que más bien tienden a confundir. Sería más simple indicar que el primer término corresponde a la sumatoria de costos de todos los tipos de equipamiento. Además la tarifa, de acuerdo con la ley 7593 tiene un periodo determinado.

Los subíndices son necesarios en cada fórmula para indicar a qué parámetro se refiere cada variable.

8.7 Se deben considerar tres aspectos: Los gastos de traslado de equipos especiales (vehículo, grúas, etc.) requeridos para la instalación, las diferencias por tiempos perdidos (viajes) por culpa del interesado en la generación distribuida, debido a que por falta de algún detalle técnico no se pueda realizar la instalación y diferencias en costos fijos como salarios de ingenieros, por razones de economías de densidad cobertura.

Estos costos se encuentran contemplados entre los costos fijos de la empresa que se encuentran en la tarifa de acceso que se calculará con la "Metodología de fijación del precio o cargo por acceso a las redes de distribución de generadores a pequeña escala para autoconsumo que se integren al Sistema Eléctrico Nacional (SEN) con fundamento en la norma AR-NT-POASEN", tramitada en el OT-252- 2014.

8.8 Fórmula 2, sobre t, de acuerdo con la ley 7593 no existe tal periodo, por lo que debería decir que es el periodo para el cual se realizan las estimaciones. Se entiende por t el periodo en que estará vigente la tarifa, tal y como lo indica el artículo 34 de la Ley 7593: "Las tarifas y los precios que fije la Autoridad Reguladora regirán a partir de su publicación en el diario oficial La Gaceta o a partir del momento en que lo indique la resolución correspondiente y, en ningún caso, podrán tener efecto retroactivo".

8.9 No queda claro cómo la Aresep determinará la cantidad y el perfil de los trabajadores necesarios para realizar el estudio de ingeniería, inspección y puesta en servicio de la interconexión del generador.

Para establecer las metodologías tarifarias la Aresep se rige por el marco legal estipulado por la Ley 7593, en este caso se aplica el artículo 31: "Para fijar las tarifas y los precios de los servicios públicos, la Autoridad Reguladora tomará en cuenta las estructuras productivas modelo para cada servicio público, según el desarrollo del conocimiento, la tecnología, las posibilidades del servicio, la actividad de que se trate y el tamaño de las empresas prestadoras.". En relación con el artículo anterior, también se aplica el artículo 16 de la Ley General de la Administración Pública establece: "1. En ningún caso podrán dictarse actos contrarios a reglas unívocas de la ciencia o de la técnica, o a principios elementales de justicia, lógica o conveniencia.".

8.10 Se considera que todo el desarrollo de la fórmula 4 es innecesario, ya que por ley debe ser así y además ni en las metodologías generales se utiliza. Por otra parte, esta metodología no se considera la posibilidad de contratar el servicio con un tercero.

La fórmula 4 es parte de la forma de cálculo del cargo por interconexión. La metodología no limita la posibilidad de subcontratar el servicio, sino el costo que le reconocerá a la empresa interdependientemente si la ejecuta ella o la contrata.

8.11 Se debe aclarar que se trata de un cargo de interconexión y no de un precio.

Para este caso en particular se consideran sinónimos, dado que en el título de la propuesta metodológica se indicó que ésta es para fijar el precio o cargo por interconexión.

(...)"

II.Que de conformidad con los resultandos y considerandos que preceden y de acuerdo con el mérito de los autos, lo procedente es: 1- Aprobar la "Metodología de fijación del precio o cargo básico por interconexión de generadores a pequeña escala para autoconsumo con el Sistema Eléctrico Nacional (SEN) con fundamento en la norma POASEN", 2- Tener como respuesta a los opositores que participaron en la audiencia pública realizada el 15 de diciembre del 2014, lo señalado en el Considerando I de la resolución que aquí se acuerda y agradecer la valiosa participación de todos en este proceso.

III.Que en sesión ordinaria 08-2015 celebrada el 26 de febrero de 2015, la Junta Directiva de la Autoridad Reguladora de los Servicios Públicos, sobre la base de la propuesta de la Comisión Ad Hoc del 24 de febrero de 2015 mediante oficio 02-CAIGD-2015, así como del oficio 152-DGAJR-2015 del 24 de febrero de 2015, acordó entre otras cosas y con carácter de firme:

Con fundamento en las facultades conferidas en la Ley N° 7593 y sus reformas, en la Ley General de la Administración Pública N° 6227, en el Decreto Ejecutivo N° 29732-MP, que es el Reglamento a la Ley N° 7593, y en el Reglamento Interno de Organización y Funciones de la Autoridad Reguladora de los Servicios Públicos y su Órgano Desconcentrado.

I.Aprobar la "Metodología de fijación del precio o cargo básico por interconexión de generadores a pequeña escala para autoconsumo con el Sistema Eléctrico Nacional (SEN) con fundamento en la norma POASEN", presentada según el oficio dictado por la Comisión Ad Hoc el 24 de febrero de 2015 mediante oficio 02-CAIGD-2015, tal y como se detalla a continuación:

"(...)

3. Marco legal La propuesta metodológica y su posible aprobación, encuentra sustento legal en la normativa que se cita a continuación:

• a)La Ley Nº 7593, Ley de la Autoridad Reguladora de los Servicios Públicos establece, en su artículo 5, que ". En los servicios públicos definidos en este artículo, la Autoridad Reguladora fijará precios y tarifas." Los servicios públicos citados incluyen, en el inciso a) del mismo artículo, el "Suministro de energía eléctrica en las etapas de generación, transmisión, distribución y comercialización".
• b)La norma vigente denominada "Planeamiento, Operación y Acceso del Sistema Eléctrico Nacional (AR-NT-POASEN)".
• c)La Junta Directiva de la Autoridad Reguladora de los Servicios Públicos, al tenor de lo establecido en el artículo 6, inciso 2), sub inciso c) del Reglamento interno de organización y funciones de la Autoridad Reguladora de los Servicios Públicos y su órgano desconcentrado se encuentra facultada para dictar y modificar las metodologías regulatorias que se aplicarán en los diversos mercados. Dicho reglamento fue publicado en el Alcance 13 a La Gaceta N° 69, del 8 de abril de 2009 y sus reformas.

De conformidad con lo anteriormente expuesto, resulta claro que la Junta Directiva de la Autoridad Reguladora es competente para emitir y modificar las metodologías tarifarias de los servicios públicos regulados, incluyendo la generación de electricidad, para lo cual deberá seguir el procedimiento de audiencia pública, según lo dispuesto con el artículo 36 de la Ley 7593. El marco legal citado provee la base que faculta a ARESEP para establecer y o modificar las metodologías regulatorias objeto de este informe.

4. Objetivo y alcance 4.1. Objetivo Los objetivos de la presente metodología son:

• a)Definir el procedimiento de fijación tarifaria para establecer el precio o cargo básico de interconexión de generadores a pequeña escala para autoconsumo con el Sistema Eléctrico Nacional (SEN), en la etapa de distribución, con fundamento en la norma POASEN.
• b)Cumplir con lo dispuesto en la norma POASEN.
• c)Contar con procedimientos de cálculo de tarifas que sean claros y verificables.
• d)Salvaguardar los intereses del consumidor final mediante el cumplimiento del servicio al costo.
• e)Asegurar el equilibrio financiero del prestador del servicio público regulado.

4.2. Alcance El alcance de esta metodología está delimitada como sigue:

• a)Se aplica en todo el territorio nacional.
• b)Se aplica para todas las empresas distribuidoras de electricidad.
• c)Se aplica para todos los generadores a pequeña escala.
• d)Se aplica tanto a las fijaciones de carácter ordinario como extraordinario, cuando corresponda, según lo estipulado en la Ley 7593.

5. Metodología 5.1. Requerimientos de información Las empresas de distribución de energía eléctrica habilitadas deberán remitir a la Autoridad Reguladora de los Servicios Públicos, a más tardar el 15 de enero de cada año, la siguiente información en formato impreso y electrónico totalmente editable con las fórmulas y enlaces correspondientes:

a. Proyecciones de nuevos generadores a pequeña escala que serán conectados a la red de distribución, de acuerdo con su segmento de mercado o su área de concesión, establecido en el Plan de Negocios de la Empresa o en los planes operativos correspondientes, al menos para un periodo de los doce meses siguientes.

b. Número de generadores a pequeña escala conectados a la red de acuerdo con su segmento de mercado o su área de concesión, durante el año.

c. Estado de la capacidad remanente de sus redes de distribución para la interconexión y operación de generadores a pequeña escala para autoconsumo, de conformidad con lo establecido en el artículo 125 de la norma AR-NT-POASEN.

d. Facturas y facturas proforma detalladas de los costos del sistema de medición requerido (medidor, base de medidor y accesorios de conexión), cuya vigencia sea de al menos un mes hábil después de iniciado el procedimiento (de aplicación de la actual metodología) y además, estas facturas no puede tener más de dos meses naturales de haber sido emitidas. En el caso de que la factura indique que los precios varían sin previo aviso, éstas no deberán tener más de dos meses naturales de haber sido emitidas.

e. Independientemente del detalle de los precios de todas y cada una de las partes que contempla el sistema de medición, las empresas distribuidoras certificarán un precio total para todo el equipamiento básico de interconexión.

Si cualquiera de los días mencionados en los puntos anteriores no es hábil, se entenderá referido al día hábil inmediato anterior.

5.2. Fórmula de precio o cargo básico por interconexión Para efectos de establecer los costos de interconexión de un generador a pequeña escala con la red de distribución se contemplaran los costos asociados a:

• i)El estudio de vialidad técnica del punto de interconexión (artículo 126 de la norma AR-NT-POASEN) e inspección preliminar.
• ii)Equipamiento para la conexión eléctrica y del sistema de medición.
• iii)Inspección final y puesta en servicio.
• iv)Adicionalmente, los costos de la interconexión contemplan los costos asociados al aseguramiento de que dicha conexión cumple con los requerimientos técnicos establecidos en la norma POASEN.

De esta manera, el costo por interconexión en colones para un generador a pequeña escala para autoconsumo se define de la siguiente manera:

Donde:

t = Periodo en el que estará vigente el cargo o precio básico de interconexión.

= Costo de interconexión en colones durante el periodo t, por tipo de equipamiento te.

= Costos de equipamiento en colones por tipo de equipamiento te durante el periodo t (ver Fórmula 2).

= Costos fijos de servicio en colones durante el periodo t (ver Fórmula 3).

te = Tipo de equipamiento (Monofásico sin registro de parámetros de calidad, trifásico sin registro de parámetros de calidad y trifásico con registro de parámetros de calidad).

El costo de interconexión básico, será el costo en colones que la empresa distribuidora de energía eléctrica le cobrará al interesado por interconectar y operar un generador (dejar operando o en funcionamiento) o instalación de generación a pequeña escala asociado a un servicio eléctrico de conformidad con la norma técnica AR-NT-POASEN y otras promulgadas por la Autoridad Reguladora.

Los costos por equipamiento en colones 𝐶𝐹𝐸 𝑡,𝑡𝑒 serán los del sistema de medición que cumplan con los requerimientos técnicos establecidos en la normativa vigente y en los requisitos técnicos que forman parte del procedimiento de interconexión y puesta en servicio aprobado por la Autoridad Reguladora. Se contemplan los siguientes costos de equipamiento:

• i)El del medidor o contador bidireccional, de acuerdo a las características establecidas en la norma técnica AR-NT-POASEN, los requisitos técnicos que forman parte del procedimiento de interconexión y puesta en servicio aprobado y la norma AR-NT-CON "Uso, funcionamiento y control de contadores eléctricos", vigente.
• ii)La base para la instalación del contador y los transformadores de instrumento cuando sean necesarios.
• iii)Los conductores de acometida y accesorios de conexión, cuando sean necesarios.

Se tendrán tres valores diferentes de costo de equipamiento (y en consecuencia, tres costos de interconexión diferentes), según sea el tipo de servicio de la siguiente manera:

1. Para servicios monofásicos residenciales, generales e industriales el costo básico debe ser el de un medidor monofásico bi direccional sencillo (sin registro de calidad).

2. Para servicios trifásicos, generales e industriales con generadores o instalaciones de generación menores o iguales a 250kW, el medidor trifásico será bidireccional sencillo (sin registro de calidad) 3. Para servicios trifásicos, generales e industriales con generadores o instalaciones de generación superiores a 250kW, el medidor trifásico será bidireccional con registro de parámetros calidad.

El costo de este equipamiento debe ser uniforme para todas las empresas y corresponderá al costo promedio en colones de las cotizaciones, facturas y facturas proforma para cada uno de los tres tipos de equipamiento indicados anteriormente.

Para efectos de disponer de la información sobre los costos de este equipamiento, la Intendencia de Energía (IE) solicitará a las empresas distribuidoras de electricidad que suministren facturas y facturas proforma que permitan determinar su costo. También, la IE solicitará dicha información de precios a los proveedores directos de estos sistemas en el mercado costarricense e internacional, tomando en consideración que para estos últimos el costo deberá incluir la disponibilidad del sistema en el territorio nacional. Igualmente podrá disponer de información del Ministerio de Hacienda sobre los costos de estos equipos, incluyendo los costos de importación, desalmacenamiento y otros, si se amerita. No obstante, lo que interesa es el precio final del sistema completo de medición que se instalaría en el servicio eléctrico con generación a pequeña escala para autoconsumo.

Con el propósito de obtener un único costo de equipamiento para el periodo t según el tipo de servicio, se procederá de la siguiente manera:

 El equipamiento deberá cumplir con los requerimientos técnicos establecidos en la norma POASEN, los requisitos técnicos que forman parte del procedimiento de interconexión y puesta en servicio aprobado y la norma AR-NT-CON "Uso, funcionamiento y control de contadores eléctricos", vigente.

 La información solicitada deberá cumplir con la vigencia establecida en el apartado de requerimientos de información.

 Los precios se indicarán en colones costarricenses. En el caso de que dichos precios se encuentren en dólares estadounidenses, para efectos de la conversión a colones, se utilizará el tipo de cambio de venta para el sector público no bancario (CRC/USD), publicado por el Banco Central de Costa Rica, en la fecha de la factura correspondiente.

Dicho cálculo lo hará la empresa distribuidora cuando este suministre la información o la IE cuando esta sea la que ha solicitado la información directamente a los proveedores.

Si los precios iniciales están en otra moneda distinta al dólar estadounidense, será responsabilidad del proveedor de información para la Aresep de solicitarla en dólares estadounidenses cuando sea el caso y posteriormente, realizar la debida conversión cambiaria a colones.

 Si se tienen varias facturas del mismo proveedor de equipamiento para una o varias empresas distribuidoras de energía eléctrica y para una o varias partes del sistema de medición, con características idénticas pero precios diferentes y con la vigencia requerida, no se tomarán en cuenta las de mayor precio.

 Cuando el precio de una o varias partes del sistema de medición contemplen descuentos con la vigencia requerida, este deberá contabilizarse en el precio total del equipamiento.

Si la modalidad del descuento es por cantidad de equipos con opción de venta y cumple con la vigencia requerida, este deberá contabilizarse en el precio total del equipamiento.

 De conformidad con la Ley 7593, la información presentada por cualquier persona física o jurídica legitimada será tomada en cuenta, siempre y cuando, sea un precio total para todo el equipamiento de interconexión, el cual debe estar debidamente fundamentado.

Esta información cumplirá con lo indicado en los párrafos anteriores en cuanto la moneda en que se expresará o realizar la respectiva conversión.

 La información por utilizar en el cálculo será la disponible a la fecha de la audiencia pública de la fijación tarifaria con base en esta metodología.

Una vez compilada y depurada la información (suministrada por las empresas distribuidoras e interesados legitimados, así como la recabada por la IE) del precio total de equipamiento, el precio o cargo utilizado para calcular el costo de interconexión, será el promedio de los precios totales del equipamiento. De la siguiente manera:

Donde:

t = Periodo en el que estará vigente el cargo o precio básico de interconexión.

= Costos fijos de equipamiento en colones por tipo de equipamiento te durante el periodo t.

= Precio total del equipamiento en colones por tipo de equipamiento te según indicador de precio s.

= Cantidad de cotizaciones, facturas y facturas proformas por tipo de equipamiento te.

s = Indicador de precios de información (depurados y compilados) sobre el precio total de equipamiento en colones de interconexión, disponible por la Aresep, en el momento de la audiencia pública.

te = Tipo de equipamiento (Monofásico sin registro de calidad, trifásico sin registro y trifásico con registro de parámetros de calidad).

Con respecto a nte, se entiende que si una cotización, factura y/o factura proforma contiene diferentes precios de varias unidades del equipamiento, cada precio se toma como un dato para ese tipo de equipamiento en particular.

Los costos fijos del servicio , contemplan el estudio de ingeniería, inspección y puesta en servicio de la interconexión del generador a pequeña escala con la red de la empresa distribuidora. El cálculo estos costos se establecen en función de los sueldos y salarios, así como las cargas sociales y provisiones del personal necesario para realizar dicha labor.

Este personal necesario se estima de la siguiente manera:

 El salario utilizado será el decretado por el Ministerio de Trabajo y Seguridad Social (MTSS) vigente al momento de la audiencia pública para cada una de las ocupaciones y tiempos jornales que se indican en el Cuadro 1. Se utilizan los salarios mínimos por jornada ordinaria para el sector privado tal y como se detalla a continuación:

Cuadro 1. Tipo de trabajador según ocupación Categoría de Salario Mínimo Fuente: Decretos de Salarios Mínimos MTSS.

(1) Corresponde a las siglas de las categorías según el Decreto de Salarios mínimos vigente.

 Las cargas sociales mínimas, provisiones y los costos de la póliza por riesgos de trabajo son los contemplados en el Cuadro 2 siguiente:

Cuadro 2. Cargas sociales según la legislación vigente Los porcentajes indicados en el Cuadro 2 pueden variar si se modifica la legislación, y se utilizarán los valores vigentes al día de la audiencia pública de la aplicación de este modelo. El factor de riesgos de trabajo (PTR) corresponde a la tarifa establecida para este tipo de trabajadores en la Sección de Suministro de Electricidad, Gas y Agua en la División de Generación, Captación y Distribución de energía eléctrica, según la Clasificación Internacional Industrial Uniforme CIIU utilizada en el manual tarifario del Instituto Nacional de Seguros (INS), vigente al día de la audiencia pública de la aplicación de este modelo, determinada sobre el costo de personal del trabajador especializado y para un profesional bachiller universitario (Bach).

El costo fijo del servicio en colones 𝐶𝐹𝑆𝑡 durante el periodo t, será la suma de los dos rubros de costos totales de los trabajadores (TES, Bach) que incluyen los sueldos y salarios, así como las cargas sociales y los costos de la póliza por riesgos de trabajo, tal y como se detalla a continuación:

Donde:

t = Periodo en el que estará vigente el cargo o precio básico de interconexión.

= Costos fijos de servicio en colones durante el periodo t.

= Costo total sueldo y salario en colones del Trabajador especializado (ver Fórmula 4).

= Costo total sueldo y salario en colones de un Bachiller universitario (ver Fórmula 6).

De acuerdo con el decreto de salarios mínimos vigente, la categoría de trabajador especializado (TES) el salario mínimo es definido por jornada ordinaria (8 horas). Con el fin de obtener el costo total de sueldo y salario de dicho rubro por el tiempo estimado requerido para la interconexión, se dividirá entre 2 el monto de salario mínimo por jornada ordinaria de este TES. Esto por cuanto el salario se presenta por 8 horas de días laboral y se requieren 4 horas; entonces el salario requerido es el salario diario dividido entre 2. A este costo en colones se le agregan las cargas sociales mínimas y provisiones que se describen en el Cuadro 2 (las cuales son actualmente un 38.67%) más el factor vigente de la póliza por riesgos de trabajo (PTR). Este costo en colones se obtiene de la siguiente manera:

Donde:

= Costo total sueldo y salario en colones del Trabajador especializado (TES) para la interconexión (4 horas).

= Salario mínimo de una jornada laboral ordinaria de un trabajador especializado.

FCS = Factor de cargas sociales mínimas y provisiones.

= Factor de la póliza de riesgos de trabajo para un trabajador especializado.

= Monto en colones de cesantía aplicable al trabajador especializado TES (ver fórmula 5).

El monto de cesantía aplicable se calcula de la siguiente manera:

Donde:

= Monto en colones de cesantía aplicable por tipo de trabajador d.

= Días de cesantía legalmente reconocidos según el artículo 29 del Código de Trabajo vigente, asumiendo que un día laboral es una interconexión de un generador a pequeña escala.

= Salario mínimo de una jornada laboral ordinaria diaria, en colones, según el tipo de trabajador d (Trabajador especializado o Bachiller universitario).

= Número total de generadores a pequeña escala interconectados en los últimos 12 meses.

D= Tipo de trabajador (Trabajador especializado o Bachiller universitario).

En el caso del Bachiller Universitario (Bach) el salario mínimo se establece mensualmente, según el decreto del MTSS y para el cual la jornada ordinaria diaria no debe exceder 8 horas diarias. Este costo total de sueldo y salario en colones es el monto salarial establecido en el decreto en mención, para el mes jornal y se divide entre 30 (proporcional días de descanso), con el fin de obtener un salario por día. De esta manera se obtiene el costo total de sueldo en colones de este rubro, al cual se le agregan el monto en cargas sociales (que es un porcentaje del salario, actualmente del 38,67%) más el monto en colones de la Póliza de Riesgos de Trabajo (que es un porcentaje del salario). Este costo en colones se obtiene de la siguiente manera:

Donde:

= Costo total sueldo y salario de un bachiller universitario para la interconexión (8 horas).

= Salario mínimo de una hora laboral de un bachiller universitario.

30 = 30 días laborales mensuales (proporcional días de descanso).

FCS = Factor de cargas sociales mínimas y provisiones.

= Factor de la póliza de riesgos de trabajo para un bachiller universitario.

= Monto en colones de cesantía aplicable el bachiller universitario (ver fórmula 5).

En resumen, el costo fijo en colones por servicio se obtiene de calcular el costo de la cantidad de horas hombres requeridas para realizar la interconexión (estudio de ingeniería, inspección y la puesta en marcha del servicio de la interconexión entre el generador a pequeña escala y la empresa distribuidora de electricidad).

5.3. Ajustes y revisiones de precios El cargo o precio de interconexión se revisará al menos una vez al año, mediante procedimiento de fijación ordinaria, de conformidad con lo que establece la Ley 7593. Con ese fin, se revisarán -y cuando corresponda, se actualizarán- todos los costos definidos en el cálculo de este precio o cargo, de acuerdo con el procedimiento descrito en esta metodología.

El procedimiento dará inicio el primer día hábil del mes de febrero de cada año, es decir, este día debe ser abierto el expediente tarifario.

5.4. Aplicación por primera vez Una vez aprobada y publicada en La Gaceta la presente metodología, las empresas distribuidoras de energía eléctrica tendrán un máximo de 30 días hábiles para suministrar la información requerida en el punto 5.1 de la presente propuesta de metodología. En caso contrario, la Autoridad Reguladora aplicará lo estipulado en el artículo 38 de la Ley 7593.

No se omite indicar que con el fin de contar con información más completa y de acuerdo con lo establecido en la presente propuesta de metodología, la IE procederá de conformidad para recabar la información pertinente.

Una vez transcurrido los 30 días hábiles en que las empresas distribuidoras de electricidad deben suministrar la información, en un plazo máximo de los siguientes 15 días la IE abrirá el expediente tarifario correspondiente.

En cuanto al monto por cesantía para la primera aplicación, se tomará como número de generadores a pequeña escala interconectados la cifra de 90 interconexiones, constituyendo esta cifra un estimado del número de días continuos laborados (mínimo establecido en el artículo 29 del Código de Trabajador).
