Construction Commences on California Geothermal Project

LCG, May 21, 2010--Construction on the Hudson Ranch 1 power project began earlier this week at a site in the Imperial Valley of Southern California. EnergySource LLC executed a 30-year, power purchase agreement (PPA) with Salt River Project (SRP) for all of the electricity generated by the 49-MW, geothermal facility. The project is scheduled to commence commercial operations in early 2012.

The geothermal project will use superheated brine reservoirs located thousands of feet below the Salton Sea and high temperature flash-technology to generate steam for power generation. The steam will be re-injected to maintain reservoir production, and power will be generated around the clock.

The renewable energy will support SRP in achieving its goal of serving 15 percent of its retail load with renewable energy by the year 2025.

The nearly $400 million project has been under development since 2006 by Catalyst Renewables and Hannon Armstrong, the majority owners of EnergySource.
