Hanford Energy Park Peaker - 92.2 MW OCGT Peaking Plant in California, USA

Hanford Energy Park Peaker is an open-cycle gas turbine (OCGT) power plant located in California, United States. With a capacity of 92.2 MW, it is a medium-scale peaking facility designed to provide rapid response during periods of high electricity demand. The plant is owned by MRP San Joaquin Energy LLC and operates on natural gas. The plant uses OCGT technology, which offers fast start-up and operational flexibility, making it suitable for balancing grid fluctuations. In the United States, OCGT plants like this one are subject to emissions regulations under the Clean Air Act, including New Source Performance Standards (NSPS) and state-level air quality permits. California's stringent environmental policies further require compliance with local air district rules. As a peaker plant, Hanford Energy Park Peaker plays a critical role in maintaining grid reliability in California's Central Valley. Its operation supports the integration of renewable energy sources by providing backup power when solar and wind generation are low. The facility's location in an agricultural region underscores its importance for local energy security.

The plant's gas-fired OCGT technology produces lower CO2 emissions per MWh compared to coal, but higher than combined-cycle gas turbines. Its operation in California's San Joaquin Valley, an area with existing air quality challenges, means emissions of NOx and other pollutants are closely monitored under state and federal regulations. The facility's relatively small capacity and peaking role limit its overall environmental footprint, though local impacts are managed through permitting and emissions controls.
