Integration of a Geothermal Plant in a System with High Renewable Energy Penetration for Desalination Plant Self-Consumption

The scarcity of water resources on the island Gran Canaria (Canary Islands, Spain) is such that 88% supply for human consumption comes from seawater desalination plants. This type process has a high specific energy consumption. an isolated electrical system low robustness. In this paper, geothermal plant designed and integrated into already non-dispatchable renewable generation (wind photovoltaic) in order to meet, based self-consumption regime, demand high-capacity plant. aim diversified improve stability management generation. Geothermal production can adapt balance between plant’s design organic Rankine cycle its resulting power 4.16 MW. Its integration significantly improves contribution renewables meeting therefore reducing dependency island’s system. mean cost with 57.37 EUR/MWh, considerably lower than conventional 153.9 EUR/MWh.
