Granite Ridge Gas Power Plant | 790 MW Facility in New Hampshire, USA

Granite Ridge is a natural gas-fired power plant located in New Hampshire, United States, with a capacity of 790 megawatts (MW). Owned and operated by Granite Ridge Energy LLC, the facility is classified as a large-scale gas power plant within the U.S. power generation sector. Its operational status is active, contributing to the regional grid's reliability. The plant utilizes natural gas as its primary fuel, a cleaner-burning fossil fuel compared to coal, resulting in lower emissions of sulfur dioxide (SO2) and particulate matter. However, it still produces carbon dioxide (CO2) and nitrogen oxides (NOx), which are regulated under the U.S. Environmental Protection Agency's (EPA) Clean Air Act, including programs like the Cross-State Air Pollution Rule (CSAPR) and the Acid Rain Program. Granite Ridge plays a significant role in meeting electricity demand in New England, particularly during peak periods. Its location near population centers allows for efficient power delivery, but also necessitates compliance with local air quality standards. The plant's environmental footprint is managed through regulatory frameworks that aim to balance energy production with environmental protection.

The plant's gas-fired operation results in lower CO2 emissions per MWh compared to coal, but still contributes to greenhouse gas emissions. Its proximity to populated areas in New Hampshire requires adherence to National Ambient Air Quality Standards (NAAQS) for NOx and other pollutants. The facility's age and technology (likely CCGT) influence its efficiency and emission rates, with modern designs achieving higher efficiency and lower emissions.
