Ormesa Complex

The Ormesa complex is located in East Mesa, Imperial County, California. The Ormesa complex consists of three plants. The various plants commenced commercial operations between 1987 and 1989. The plants utilize binary and flash systems. The Ormesa complex had a generating capacity of 40 MW. The Ormesa complex sells its electrical output to Southern California Edison Company (Southern California Edison) under an amended power purchase agreement. In 2016, Ormat entered into a 25-year PPA with SCPPA that will begin on November 30, 2017 and will supersede the current PPA.

In 2003 Ormesa 1 and Ormesa 2 plants in complex have been replaced with the latest equipment and technology:

  • Raising the power production of the plant
  • Lowering the number of plants in the complex
  • Reducing the amount of resources required for the production and maintenance of the plant
  • Reducing the number of control units needed for the plants
  • Providing simplicity of plant operation
