Overview
Henrietta Peaker is a 98 MW OCGT gas-fired power plant in California, USA, operated by MRP San Joaquin Energy LLC. It provides peaking capacity to support grid reliability.
Henrietta Peaker is an open-cycle gas turbine (OCGT) power plant located in California, United States. With a capacity of 98 MW, it operates as a peaking facility, typically running during periods of high electricity demand. The plant is owned by MRP San Joaquin Energy LLC and is currently operational. As an OCGT plant, Henrietta Peaker uses natural gas as its primary fuel. OCGT technology is known for its quick start-up capabilities, making it suitable for meeting peak load demands. The plant operates under the regulatory framework of the U.S. Environmental Protection Agency (EPA), including the Clean Air Act and associated programs such as the Acid Rain Program and the Cross-State Air Pollution Rule (CSAPR). Henrietta Peaker plays a key role in the California electricity grid by providing flexible generation capacity. Its location in the San Joaquin Valley places it in an area with significant agricultural and urban energy needs. The plant's relatively small capacity and peaking operation mode help support grid stability during high-demand periods.
Environmental context
The plant's gas-fired OCGT technology results in higher CO2 emissions per MWh compared to combined-cycle plants, but lower than coal-fired generation. Its peaking operation means it runs only during high-demand periods, reducing overall emissions. The San Joaquin Valley faces air quality challenges, and the plant's emissions are subject to EPA regulations including NAAQS and CSAPR. Proximity to populated areas may influence local air quality impacts.
