The Salton Sea geothermal resource there has been under development since 2006 by Catalyst Renewables and Hannon Armstrong, the majority owners of EnergySource.

Project debt financing was raised by an eight member bank syndicate led by ING Capital, Societe Generale and West LB. Additional equity was raised from GeoGlobal Energy, a privately held geothermal energy-focused investment firm backed by Mighty River Power , a state-owned New Zealand utility.

EnergySource President Dave Watson calls the site one of North America’s best geothermal resources.
