Bennett Mountain Gas Power Plant | Idaho, United States

Bennett Mountain is a gas-fired power generation facility located in Idaho, United States. With a capacity of 172.8 megawatts, it operates as a medium-scale plant within the U.S. power sector, contributing to the region's electricity supply. The plant is owned by Idaho Power Co, a major utility serving the Pacific Northwest. The facility utilizes natural gas as its primary fuel, a common choice for flexible and relatively lower-emission power generation compared to coal. In the United States, gas plants like Bennett Mountain are subject to federal regulations under the Clean Air Act, including National Ambient Air Quality Standards (NAAQS) and the Acid Rain Program, which set limits on sulfur dioxide and nitrogen oxides emissions. The plant's operational status is active, indicating it meets current regulatory requirements. Bennett Mountain plays a role in supporting grid reliability in Idaho, particularly during peak demand periods. Its location in a region with growing energy needs underscores its importance for local communities. The plant's environmental footprint is managed through compliance with state and federal emissions standards, aligning with broader trends in the U.S. power sector toward cleaner natural gas generation.

Bennett Mountain's gas-fired operations produce lower CO2 emissions per megawatt-hour compared to coal plants, but still contribute to greenhouse gas emissions. Its location in Idaho, a state with significant hydropower resources, means it may serve as a backup during low hydro availability. Proximity to populated areas could influence local air quality, though modern gas plants typically employ emissions controls to meet NAAQS standards.
