The project is a solar/geothermal plant and constructed by Enel Green Power.

POWER Engineers Inc. provided detailed engineering services for the original binary geothermal plant as well as for the 2 MW Concentrating Solar Power (CSP) system.

[6] Covering 240 acres (97 ha), the plant has 89,000 polycrystalline silicon solar panels and has a generation capacity of 26 MW.

The photovoltaic generation was designed to make up for the reduction in output from the geothermal plant due to high ambient temperatures during summer midday hours.

[5] An additional 2 MWe (17 MWth) using concentrated solar power (CSP) in parabolic troughs began construction in 2014.
