Our plants employ state-of-the-art technologies with proven track records of reliability and performance. Our “combined cycle” plants are among the most efficient base load power plants in the industry. These plants employ efficient gas turbines, a system to recover exhaust energy from the gas turbines to produce steam, and a steam turbine to convert that energy to additional electricity. Our “simple cycle” facilities are designed for quick start, reliability, and flexibility to meet electricity load during peak periods of demand.

Combined Cycle Technology

The following graphic depicts how combined cycle technology is employed at our Tracy Combined Cycle Plant. The Arlington Valley Plant and Griffith Energy Plant have similar configurations, but use mechanical draft cooling towers instead of an air cooled condenser.


Simple Cycle Gas Turbine Technology

The following graphic depicts gas turbines in a simple cycle configuration, as is the case at our Hanford Peaker and Henrietta Peaker facilities.
