Solar Energy to Power Geothermal Plant

Northern California Power Agency (NCPA) and SPG Solar, announced that they will together to build a 1 megawatt (MW) single-axis solar tracking system that will provide renewable energy to an existing pump station that supplies the NCPA Geysers Geothermal Energy Plant.

The array will be used to collect solar power to pump wastewater into the geysers, which is in turn used to generate geothermal power. The photovoltaic array will start generating clean renewable power beginning in September 2008.

The $8.2 million installation consists of 6,300 solar modules that will produce 2.2 million kilowatt hours of electricity annually. The solar plant will supplant PG&E-provided grid power that had been powering the pumps.

“The significance of this project is the creative use of clean energy and a system design in which we will deploy one renewable energy source to power another,” said Jim Pope, NCPA General Manager. “This solar investment demonstrates our continued commitment to investing in environmentally responsible resources, reducing our carbon footprint and lowering costs for our utilities and public power customers.”
