SDG&E Adds 40 MW of Geothermal

San Diego Gas & Electric (SDG&E) has announced that it has signed a power-purchase agreement (PPA) with Esmeralda Truckhaven to supply 40 megawatts (MW) of geothermal energy to the region’s electric system. This agreement will boost SDG&E’s total geothermal energy supply to 60 MW produced from Esmeralda facilities located in Imperial County, California.

In addition to the Esmeralda contract, SDG&E also recently added to its renewable-energy portfolio when the company received CPUC approval on its agreement with Envirepel . This agreement is for 1.5 MW of biomass energy to be produced at a facility being developed in Vista, California. Five percent of SDG&E’s energy-resource mix comes from renewable resources such as wind, solar, biomass and geothermal.

“The Imperial County is a renewable mecca for our region’s future energy supply,” said Debra Reed, president and chief executive officer of SDG&E. “As we continue to aggressively seek out renewable sources of energy to meet the state’s 20-percent-by-2010 mandate, we will look to renewable developers such as Esmeralda to help us expand our renewable energy footprint throughout the county.”
