Mint Farm Generating Station - Gas Power Plant in Washington, USA

Mint Farm Generating Station is a gas-fired power plant located in Washington, United States, with a capacity of 319 MW. Owned by Puget Sound Energy Inc, the facility is operational and contributes to the regional power grid. This scale places it as a mid-sized gas plant in the US power generation sector. The plant operates under the regulatory framework of the US Environmental Protection Agency, including the Clean Air Act (CAA) and its associated programs such as the Acid Rain Program and the Cross-State Air Pollution Rule (CSAPR). Gas-fired plants like Mint Farm typically use combined cycle or simple cycle technology, with lower emissions compared to coal-fired units. The specific technology type is not detailed, but modern gas plants often achieve high efficiency. As a gas-fired facility, Mint Farm Generating Station has a lower carbon and pollutant footprint relative to coal plants, though it still emits CO2 and NOx. Its location in Washington, a state with a mix of hydro, gas, and renewable energy, supports grid reliability. The plant serves the local community by providing dispatchable power to complement intermittent renewable sources.

The plant's gas fuel type results in lower CO2, SOx, and NOx emissions compared to coal, but still contributes to greenhouse gas emissions. Its location in Washington, a state with significant hydropower and growing renewables, means it likely operates as a mid-merit or peaking plant. Gas plants are often sited near load centers. The 319 MW capacity indicates a moderate environmental footprint relative to larger coal or gas plants.
