McClure Diesel Power Plant | California Peaking Facility

McClure is a diesel power plant located in California, United States, with a capacity of 142.4 MW. Owned by Modesto Irrigation District, the facility is operational and serves as a peaking plant, providing electricity during periods of high demand. Its location in California places it within a state with stringent environmental regulations. The plant uses oil as its primary fuel, a common choice for peaking plants due to its quick start capabilities. Diesel plants typically operate with internal combustion engines. The facility operates under the regulatory framework of the US Environmental Protection Agency (EPA), including the Clean Air Act and state-level emissions standards from the California Air Resources Board (CARB). As a peaking plant, McClure plays a critical role in maintaining grid stability in California's energy market. Its capacity of 142.4 MW places it in the medium-scale range for diesel plants. The facility's environmental impact is managed through compliance with emissions limits and permitting requirements, contributing to the region's energy diversity.

The McClure plant's use of oil as fuel results in higher CO2, SOx, and NOx emissions compared to natural gas. Its location in California subjects it to strict emissions regulations under the Clean Air Act and CARB rules. Proximity to populated areas may increase local air quality concerns, though the plant's peaking operation limits runtime. Older diesel engines may have lower efficiency and higher emissions per MWh.
