Abstract
En este trabajo se describe la evolución que han tenido las energías renovables no convencionales en el SIC y SING, abordando las externalidades positivas y negativas asociadas a la incorporación de las tecnologías cíclicas, desde el punto de vista de la seguridad del sistema y de los efectos sobre los agentes que participan del mercado.Considerando que la Ley 20.698 establece una cuota creciente de ERNC de un 20% al año 2025, resulta evidente que los requerimientos operacionales y de flexibilidad sobre el parque térmico irán en aumento, con el objetivo de aprovechar los recursos renovables de bajo costo, los cuales reducirán los costos operaciones del sistema.No obstante, para poder amortiguar las solicitaciones que imponen las tecnologías cíclicas al sistema y además mantener los estándares de seguridad y calidad del SEN, se requiere de la prestación de Servicios Complementarios (SSCC), siendo una de las alternativas idóneas las centrales hidroeléctricas de embalse o de bombeo, ciclos combinados de gas natural, bancos de baterías (BESS) u otra tecnología que permita suministrar los requerimientos operacionales existentes y las necesidades a futuro. Los nuevos SSCC para el SEN y la forma como se van a remunerar estos servicios, estará contenido en el reglamento de SSCC que publicará la CNE a fines de 2017.Finalmente, considerando que la Ley 20.936 establece que los costos de SSCC que debe asumir el usuario final, corresponde al pago de las inversiones asociadas a la nueva infraestructura y sus costos anuales de mantenimiento eficiente, se plantea una metodología que permite estimar los costos que serán traspasados al usuario final, asociado a los SSCC exigidos por el Coordinador Eléctrico Nacional a implementar en el corto plazo.
This paper describes the evolution of unconventional renewable energies in the SIC and SING, addressing the positive and negative externalities associated with the incorporation of cyclical technologies, taking into account system security and the effects on the agents participating in the market. Considering that Law 20.698 establishes an increasing share of NCRE of 20% by the year 2025, it is evident that the operational and flexibility requirements on thermoelectric units will increase with the objective of taking advantage of low-cost renewable resources, which will reduce the system's operating costs. However, to be able to cushion the demands created by cyclical technologies on the system and also to maintain the safety and quality standards of the SEN, Complementary Services (SSCC) are required. Some optimal alternatives are hydroelectric reservoir or pumping systems, combined natural gas cycles, battery banks (BESS) and other technologies that provide for existing and future operational requirements. The new SSCC for the SEN and the way these services are to be profited will be established in the SSCC regulation that will be published by the CNE at the end of 2017. Finally, considering that Law 20.936 establishes that the SSCC costs should be covered by the end user, corresponding to the payment of the investments associated with the new infrastructure and the annual costs of efficient maintenance, a methodology is proposed that allows to estimate the costs that will be Transferred to the end user, associated with SSCC required by the National Electrical Coordinator to implement in the short term.
