The photovoltaic system adds 26 MW to the 33 MW of the Stillwater geothermal power plant.
This is the first renewable energy project in the world that combines the continuous generation capacity of binary-cycle, medium-enthalpy geothermal power with the peak capacity of solar power, allowing a better match with NV Energy's customer needs. NV Energy has a contract to buy all the energy that will be generated by the plant.
The solar power plant generates around 40 million kWh of clean energy per year, enough to meet the needs of 15,000 American households as well as avoiding the emission of around 28,000 metric tons of CO2 into the atmosphere each year.
Combining two technologies to produce electricity from renewable sources at the same location increases the generation of zero-emission energy, but also makes it possible to use the same infrastructures such as, for instance, electrical interconnection lines, thereby further reducing environmental impact.
