With its 26 MW of photovoltaic capacity, to which the capacity of 33 MW is integrated geothermali, The Stillwater Alternative Energy Plant in Nevada is the world's first solar-geothermal hybrid power plant. Thanks to the 89,000 panels recently installed by the company Enel Green Power, with a total capacity of 59 MW of clean energy, the plant is able to power more than 50,000 homes.
Why the choice of matching renewables?
Solar and geothermal they are both great sources of clean energy, however solar energy does not have a continuous cycle, it needs a backup for when the sun is not shining. In this perspective, the geothermal. A valid clean alternative capable of smoothing out the gaps in the sector ofsolar power.
But not only that, during the day when the demand is greater, there is the advantage of receiving energy from both sources. With 40 million dollars, theStillwater plant is among the geothermal sites in Nevada to have benefited from investments by the DOE to accelerate the development of geothermal energy.
DOE Secretary Steven Chu says: "As the first of its kind in the world, this project demonstrates how we can harness renewable energy sources to provide clean energy for American households and businesses and distribute every available source of American energy.".
The solar plant will produce clean energy equal to 43 million kilowatt hours a year, guaranteeing clean energy to 16,000 American households: an estimated 30,000 tons of emissions will be avoided carbon dioxide in the atmosphere per year.
The combination of the two generation technologies from renewables in the same site will procure the production of zero emission energy of about 200 million kilowatt hours per year, with 140,000 tons of CO2 avoided every year. It will also allow for the provision of the same infrastructures, such as, for example, the interconnection power lines, thus further reducing theenvironmental impact. Thanks to this plant, the total installed clean energy capacity in North America exceeds 1,000 MW.
