“…The transition to sustainable electricity generation and its challenges in island environments analyzed by [1,2], studying the reliability of total renewable electric systems under different scenarios, by [3], offering an approach between energy poverty and its correct energy planning, by [4], indicating the challenges facing the Canary Islands in terms of increasing the renewable energy penetration versus the security of the supply, or by [5,6], analyzing a literature review and the life cycle of renewable energy generation on islands, have highlighted the importance of decarbonization and a greater penetration of renewable energies, as well as the need for a broader vision regarding the management of energy resources and their corresponding technologies. The problems that arise when implementing decarbonization strategies are exacerbated in weakly interconnected island systems [6,7]. The island electricity systems (IESs) of the Canary Archipelago (Spain) face environmental, economic, and social sustainability challenges, as they rely heavily on imported fossil fuels for electricity generation [1,8], and aspects such as the optimization of the energy mix from an economic perspective has been analyzed by [8], but considering 100% renewable generation.…”

The penetration of renewable energies in island electricity systems (IESs) poses a series of challenges, which include, among others, grid stability, the response to demand, and the security of the supply. Based on the current characteristics of electricity demand on the islands of the Canary Archipelago (Spain) and their electricity production systems, this study presents a series of alternative scenarios to reduce greenhouse gas (GHG) emissions and increase the penetration of renewable energies. The goal is to optimize combustion-based (nonrenewable) energy production and combine it with renewable-based production that meets the requirements of dynamic response, safety, scaling, and integration with nonrenewable systems in terms of efficiency and power. As verified in the research background, the combination of power producing equipment that is generally employed on the islands is not the best combination to reduce pollution. The aim of this work is to find other possible combinations with better results. A methodology is developed and followed to obtain the lowest GHG production and to determine the measures to be applied based on: (a) changing the fuel type by switching to natural gas in the equipment that allows it; (b) using optimal combinations of the least polluting energy production equipment; (c) integrating, to the extent that it is possible, the Chira-Soria pumped hydroelectric energy storage plant into the Gran Canaria electricity system. A series of alternative scenarios are generated with different operating conditions which show the possibility of increasing the renewable installed capacity in the Canary Islands by up to 36.78% (70% in Gran Canaria), with a 65.13% reduction in GHG emissions and a 71.45% reduction in fuel consumption. The results of this study contribute, through the different measures determined through our research, to the mitigation of GHG emissions.
