Spain’s Abengoa will be engineering, procurement and construction (EPC) contractor at Palen, and provide operation and maintenance services once it is online.

Califiornia-based Brightsource will provide the solar equipment and plant-design services.

Palen consists of two 250MW plants in a Department of Interior Solar Energy Zone in Riverside County, California.

The partners "will work together to permit and finance" the project, says a statement.
