Yuma (United States)
Generation, Cogeneration
The Project
The Yuma cogeneration facility uses natural gas as the fuel for its turbine and efficiently produces energy in two forms – electric and thermal (steam). The exhaust from the gas turbine waste heat that would otherwise dissipate into the atmosphere is recycled into a heat recovery steam generator (boiler) and high-pressure steam is produced which drives the steam turbine. Then, a portion of the steam is extracted and delivered to the thermal host – an industrial entity located adjacent to the power plant which uses the steam for processing and cooling. This method of utilizing steam that has already performed useful work increases the efficiency of the plant and maximizes fuel use.
CalEnergy Generation's Yuma cogeneration plant provides approximately 50 net megawatts to San Diego Gas & Electric Company under a 30-year power purchase agreement and provides steam to Queen Carpet, Inc. under a steam sales agreement.
Environment
Natural gas is one of the cleanest fossil fuel sources in the world and Yuma's cogeneration plant utilizes low-cost, highly efficient natural gas as its fuel source. Since beginning operation in 1994, the Yuma facility has diligently maintained all safety and environmental compliances.
