Eight islands comprising 1 431 603 inhabitants make up the volcanic archipelago of Hawaii, located in the Pacific Ocean, off the southwestern coast of the United States (California); distance that makes them some of the most isolated land in the world. Geographical isolation, which has always caused a great difficulty for the island's energy supply, making Hawaii's electricity system one of the most expensive in the USA.
The introduction of the first photovoltaic and wind power plants (602 MW) led to the 23% the contribution of renewables to electricity consumption; but the state utility presented an energy strategy that aims at 100% coverage by 2045becoming the first American state to be independent of oil. The project in question, known as Energy Excelerator, see one partnership between public and private, with investments of $ 400 million. It will have one in the center smart grid, equipped with accumulators and smart meters, for the optimal integration of renewable plants: 36 MW of photovoltaics feed-in-tariff, 872 MW of large photovoltaic, 1215 MW of small photovoltaic on roofs, 529 MW of wind Onshore, 800 MW of wind power offshore, 118 MW of geothermal power plants and 21 MW of hydroelectric.
