Calpine Corporation

Calpine Corporation is a major U.S. power company, capable of delivering nearly 24,000 MW of clean, cost-effective, reliable, and fuel-efficient electricity to customers and communities in 18 U.S. states . Calpine owns, leases, and operates low-carbon, natural gas-fired, and renewable geothermal power plants.

Calpine operates 19 geothermal power plants at The Geysers region of Northern California, which represents about 25% of California ’s green energy production. Currently more than 350 active production wells provide steam that is piped directly into turbines to generate electricity. Also, at The Geysers facility, 11 million gallons of treated wastewater from Santa Rosa are pumped daily for injection into the geothermal reservoir.

Calpine continues to develop geothermal projects, including a $200 million program launched in 2007 to enhance geothermal production at The Geysers by up to 80 MW. The company is also reviving Geyser operations by rebuilding eight older geothermal turbines. This project will repower units with a total current output of 250 MW.

Cal Energy/Berkshire Hathaway Energy

Berkshire Hathaway Energy, based out of Des Moines, Iowa, is an international leader in the development and production of energy from diversified fuel sources including geothermal, natural gas, and hydroelectric. Its five U.S. energy platforms include MidAmerican Energy Company, PacifiCorp, Northern Natural Gas, Kern River Pipeline, and CalEnergy Generation.

CalEnergy Generation, which was founded in 1971, originally provided consulting and development services for geothermal power production facilities in North America. By the late 1970s the company began a transition from a service-based provider to an independent power producer. Throughout the 1980s and early 1990s, in addition to developing its own projects, CalEnergy Generation acquired the assets of several U.S. geothermal energy producers and explored opportunities in energy markets around the world.

The company continued this in 1998 with the acquisition of MidAmerican Energy and a year later the company reorganized as MidAmerican Energy Holdings Company. The company changed its name to Berkshire Hathaway Energy effective May 1, 2014. Currently, CalEnergy Generation operates 10 generating geothermal plants near the Salton Sea in Southern California's Imperial Valley. The combined generating capacity at Salton Sea is approximately 340 net MW. CalEnergy Generation is developing new projects in the Salton Sea geothermal area, including the permitting of its Black Rock Project, which will consist of three new 50-MW geothermal plants.

Northern California Power Agency

The Northern California Power Agency (NCPA) is a California-based public agency that is devoted to the purchase, generation, transmission, pooling, and conservation of electrical energy and capacity for its members. Established in 1968, NCPA is a California Joint Action Agency that provides clean renewable energy to its 17 member communities and districts in Northern and Central California.

NCPA operates two geothermal power plants of 110 MW each at The Geysers geothermal field, located in Northern California. The agency also owns and operates the 70 deep production wells that supply these power plants with steam. In addition, the geothermal project includes eight deep injection wells used to resupply the geothermal reservoir with power plant excess geothermal condensate and treated effluent from nearby communities to create additional steam.  NCPA operates and maintains the 26 mile pipeline and pumping stations that supply up to 8 million gallons per day of the treated effluent used for injection.

In the fall of 2008, a 1-MW, 30% capacity factor solar photovoltaic project will supply peak power to one of the effluent pumping stations whereby a renewable project (solar) is used to support another renewable project (geothermal), all the while disposing of treated wastewater for the nearby communities of Lake County. A second 1-MW solar project is also planned for the fall of 2009 that will supply peak power for another of the effluent pipeline pump stations.

Imperial Irrigation Disctrict

Imperial Irrigation District, headquartered in Imperial, California, is a public agency whose mission is to provide reliable, efficient and affordably priced water and energy service to the communities it serves. It owns land in the Imperial Valley, where there are approximately 2,500 megawatts of undeveloped geothermal resources - more geothermal generating capacity than anywhere else in the U.S.

IID has served as the transmission provider for the geothermal industry since its establishment in Imperial County in the late 1970’s. In 2013, IID had 600 megawatts of reserved capacity on its transmission system for the 20 geothermal energy plants it served. This was enough energy to meet the needs of almost half a million households.

IIID’s recent Salton Sea Restoration & Renewable Energy Initiative will leverage funds generated by new renewable energy projects located at the Salton Sea to help finance activities for air quality management and habitat restoration. It will focus on developing up to 1,700 megawatts of new geothermal energy at the Salton Sea – enough to power more than one million homes.
