For the application of this regulation, the terms mentioned shall have the following meaning:
. Self-consumption (Autoconsumo): use of the energy generated by the PDER to supply their own demand at the same site where it is produced.
. Penetration capacity (Capacidad de penetración): maximum capacity of each electrical circuit of the SEN to be able to accept distributed energy resources without these affecting its operation, in accordance with the applicable regulations issued by the ARESEP for this purpose.
. Interconnection contract (Contrato de interconexión): the accessory legal instrument signed between CNFL and the PDER that establishes the general and specific conditions under which a DER will interact with the distribution network and its impact on the SEN at the common interconnection point (punto de interconexión común), the commercial and regulatory conditions of access. The termination of the interconnection contract or its breach does not affect the validity and effectiveness of the electricity supply contract.
. Principal contract or electricity supply contract (Contrato principal o contrato de suministro de energía): the principal contract signed between CNFL and the customer (persona abonada) for the supply of electricity, in which the conditions, technical and commercial requirements under which the electric service will be provided are established, as well as the obligations, rights, duties and sanctions to which the parties commit, in strict adherence to the current regulations and laws.
. Excess energy (Excedentes): electrical energy generated from renewable energy sources and injected into the electrical distribution network, once the distributed generator has satisfied their own demand.
. Distributed generation for self-consumption (Generación distribuida para autoconsumo): set of technologies or equipment necessary for the generation of electrical energy from renewable energy sources used by the distributed generator.
. Distributed generator (Generador distribuido): individual or legal entity that owns and operates a small-scale distributed generation system for self-consumption, from renewable energy sources, in the operating mode with delivery of excess energy (excedentes) to the network and operating mode without delivery of excess energy (excedentes) to the network . Operation with delivery of excess energy (excedentes) to the network (Operación con entrega de excedentes a la red): mode of distributed generation for self-consumption, in which the distributed generation system is interconnected with the SEN, so that it can allow the injection of excess energy (excedentes) into the distribution network.
. Operation without delivery of excess energy (excedentes) to the network (Operación sin entrega de excedentes a la red): mode of distributed generation for self-consumption, in which the distributed generation systems have technological mechanisms to manage the excess energy (excedentes) at the generation point and make the delivery of excess energy (excedentes) impossible while operating in parallel with the SEN.
. Operator of the National Electric System (Operador del Sistema Eléctrico Nacional, OS): technical unit that has the responsibility of planning, directing and coordinating the operation of the national electric system and the national electric market to satisfy the country's electrical demand, as well as the coordination and execution of energy transfer at the regional level, according to what is stipulated in national and regional regulations.
. Customer (Persona abonada): individual or legal entity that has signed one or more contracts for the use of electrical energy.
. Distributed Energy Resources (DER): are generation and storage technologies connected directly to the distribution network, capable of exporting active electrical power. For the purposes of this regulation, DER are understood as: (a) distributed generation systems for self-consumption and (b) energy storage systems . National Electric System (Sistema Eléctrico Nacional, SEN): the power system composed of the following interconnected elements: generation plants, the transmission network, the distribution networks, storage systems and the electrical loads of users.
