Tenaska Imperial
Solar Energy Center West
Imperial County, California


Concentrated Photovoltaic (PV) technology is currently being proposed for the project. Photovoltaics is a method of generating electrical power by converting solar radiation into direct current electricity using semiconductors. Photovoltaic power generation employs an array of solar panels that do not produce noise or emit any greenhouse gases.

Key Facts

Electric Capacity (approximately)
Up to 150 megawatts (MW) of renewable power, enough electricity to meet the needs of more than 54,000 California homes.
Photovoltaic generation. Photovoltaic technology converts sunlight directly into electricity with panels that do not produce noise or emit any greenhouse gases. This technology uses water only for periodic cleaning. This minimal use of water is important in water-scarce Imperial County.
The West project site is on more than 1,100 acres of former agricultural land in Imperial County about five miles west of the city of El Centro.
Imperial County approved the project in 2011. The project is expected to be under active construction in 2013. Completion is expected in 2015.
Economic Impact
This project would boost the local economy over the construction period and provide as many as 300 new jobs at peak construction. This activity will generate still more jobs in the region.
Minimal Water Use
Photovoltaic technology converts sunlight directly into electricity and therefore has minimal water supply requirements, an important consideration for the Imperial Valley. Water use would be primarily for cleaning the panels and dust mitigation.
Transmission Interconnection
The project would connect with the California Independent System Operator (CAISO) at the existing Imperial Valley electric transmission substation located on BLM land in the Yuha Desert. Needed transmission lines would be located within a BLM land tract currently used for high voltage electricity transmission.
Project Developer/Owner
Tenaska Solar Ventures, an affiliate of Tenaska, is developing the project. CSOLAR IV West, LLC, a Tenaska affiliate, is owner of the project.
