USA, Nevada:

World's First Hybrid Geothermal-Solar Plant Is Online (Sustainable Business.com)


The world's first hybrid geothermal-solar plant is now online in Nevada. The 59 megawatt (MW) Stillwater project includes 26 MW of solar and was built by Enel Green Power North America. All the power is being sold to the utility, NV Energy.

The integration of the two technologies brings significant benefits: solar provides electricity during peak hours when thermal efficiency of the geothermal unit is lowest, enabling base load power, and there are cost savings from a shared infrastructure and transmission connection. There's also a smaller environmental footprint per unit of renewable energy produced and delivered.

The geothermal plant has been operating since 2009 and 89,000 solar PV panels are on an adjacent 240 acres.
