Decarbonization scenarios assessment under local renewable energy communities: Ispaster Municipality

This work assesses future scenarios in the Municipality of Ispaster (Spain) for the development of the renewable energy community (REC) and foresee how the local resources and flexibility measures will support energy and decarbonization targets (2030). Three scenarios are explored with a progressive increase of renewables, electrification, and independence of national grid: Reference, Black-Out and Energy Island. The results show that DH expansion will integrate biomass boilers, biomass CHP and geothermal heat pumps where electricity prices is the main driver for the operation of the system. EVs leads future electricity demand. PV and batteries expansion will be necessary for blackout prevention. This expansion allows additional flexibility services to the grid being able to reduce 7% the dependence with national electric grid. CHP biomass can allow to become an energy island to the municipality covering electricity demand during the winter season and energy storages are fundamental for energy balance.
