Headquartered in Southern California, the company was formed in 2006 as an independent power producer to develop geothermal projects in the Salton Sea resource area, one of the largest and highest temperature geothermal resources in North America. Its projects are being advanced by a team with extensive experience in every stage of renewable energy development: project origination, permitting, well field development, resource acquisition, plant engineering, construction, project financing and operations.


In early 2012, EnergySource successfully completed the construction and commenced operations of its first major power plant, the 55 megawatt  John L. Featherstone plant at Hudson Ranch Power I, the first stand-alone geothermal plant built in the Salton Sea resource in 20 years. The plant design integrates advanced technological innovations, sophisticated alloy materials and environmentally-friendly processes for extracting strategic minerals. Operating availability has been greater than 95 percent since it began selling its power in March 2012 under a 30-year power purchase agreement with Salt River Project, a power and irrigation district in Tempe, Arizona. The plant’s clean energy serves some 50,000 homes in the SRP service area.


EnergySource has a pipeline of geothermal projects in development, which over the coming decade will help California and Southwestern utilities meet their state-mandated renewable energy requirements while contributing to reduction of greenhouse gas emissions throughout the region.

In the Local Community

Community Benefits
The John L. Featherstone Plant created more than 200 jobs during construction and today has a team of more than 45 employed full time, 35 to support plant operations and another 10 originating and developing new power projects. During its construction, EnergySource served as general contractor to the Featherstone Plant, with support from AMEC, its engineering contractor, and PMC, its construction contractor. The Imperial Irrigation District provides electrical interconnection, transmission and water supply to the Featherstone Plant. The agreements between EnergySource and the District provide an additional boost to the local economy.

Environmental Stewardship
Protection of the environment and biological resources is a first-order EnergySource priority. EnergySource was awarded the Geothermal Energy Association's Environmental Stewardship Award for fostering outstanding environmental stewardship through the use of geothermal systems. The award nominations were evaluated by and presented in conjunction with the Environmental and Energy Study Institute (EESI). EnergySource designed and implemented the best available control technology to minimize air emissions and protect native wildlife during construction of its projects.
