Protermosolar ha realizado el informe Transición del Sector Eléctrico: Horizonte 2030 en el que proyecta un escenario para ese año sin centrales de carbón ni nucleares, con un 85,6% de generación renovable frente al 62,1% de la Comisión de Expertos (CdE), con una reducción del 82% de vertidos y del 60% de emisiones respecto al informe de la CdE y a menos de 5 c€/kWh. Además, el estudio contempla un menor respaldo de los ciclos combinados que el informe de la CdE, por lo que las energías renovables alcanzarían una penetración en la demanda final de energía del 34%, cumpliendo los objetivos de la UE. La clave está en repartir la potencia solar contemplada por la CdE entre fotovoltaica y termosolar y despachar las nuevas centrales termosolares con almacenamiento a partir de la puesta de sol. Los planificadores y responsables energéticos deben entender las diferencias entre las energías renovables para conseguir satisfacer la demanda de forma segura, barata y sin emisiones, cosa que los mercados, comparando exclusivamente costes de generación, no realizan. Este estudio es una propuesta alternativa al informe de la Comisión de Expertos para la Ley de Transición Energética y Cambio Climático Protermosolar has released its report “The Power Sector Transition: 2030 Horizon”which projects a scenario for that year without coal or nuclear power stations; with 85.6% of renewable generation compared to the 62.1% from the Committee of Experts (CdE); with a reduction of 82% of waste and 60% of emissions compared to the Committee’s report; and at a cost of under 0.05€/kWh. The study envisages less back-up from combined cycles than the CdE report meaning that renewable energies achieve a penetration of final energy demand of 34%, meeting the EU targets. The key lies in distributing the solar capacity forecast by the CdE between PV and CSP and dispatching new CSP plants with storage after sunset. Planners and those responsible for energy must understand the differences between the renewable energy technologies in order to cover demand securely, cost-effectively and emissionsfree, something that the markets, exclusively comparing generation costs, do not. This study provides an alternative proposal to the report by the Committee of Experts for the Law on Energy Transition and Climate Change. The study is drawn up by the CSP business association and is based not on computer models, but on a projection created from the actual hourly generation data over past years of the proposed mix. Its conclusions therefore correspond to actual verification of the capacity of an optimised renewables mix, identifying the real back-up capacity that would be needed. The report concludes that coal, nuclear and part of the current combined-cycle stock would be surplus to requirements. The scenario forecast by Protermosolar covers the same demand to 2030 as that projected by the CdE and with the same renewable output of 106 GW, broken down as follows: 33 GWwind; 25 GW PV; 20 GW CSP and 5 GW from other renewables. ESCENARIO 2030: 85% DE GENERACIÓN RENOVABLE, SIN CARBÓN NI NUCLEAR, A UN COSTE INFERIOR A 5 C€/KWH La patronal termosolar, Protermosolar ha presentado una propuesta alternativa al informe de la Comisión de Expertos para la Ley de Transición Energética y Cambio Climático. El estudio está basado en datos reales de generación y demanda horarias, proyectados a 2030, y propone un nuevo mix con una reducción de su coste, de la emisiones y del respaldo necesario de las centrales convencionales. El informe destaca que despachar la termosolar a partir de la puesta de sol, de forma complementaria a la fotovoltaica permite reducir las necesidades de respaldo y abaratar costes. Asimismo, señala que eólica y solar serán los pilares de la generación del futuro, con la hidráulica y la biomasa apoyando por su flexibilidad de despacho. Los datos del informe reflejan que es posible una reducción del 82% de los vertidos y del 60% de emisiones de CO2 respecto al informe de la Comisión de Expertos. 2030 SCENARIO: 85%OF RENEWABLE GENERATION, WITHOUT COAL OR NUCLEAR, AT UNDER 0.05€/KWH The CSP business association, Protermosolar, has submitted an alternative proposal to the report from the Committee of Experts for the Law on Energy Transition and Climate Change. The study is based on real hourly generation and demand data, projected to 2030, and proposes a newmix with a reduction in its cost, emissions and the necessary back-up from conventional power plants. The report highlights that dispatching CSP after sunset, to complement PV production, can reduce the need for back-up and thus bring down costs. Similarly, it indicates that wind and solar will be the pillars of generation of the future, with hydro and biomass providing support due to their dispatch flexibility. The report’s data demonstrates that it is possible to reduce waste by 82% and CO2 emissions by 60% compared to the report released by the Committee of Experts.
