Newington Gas Power Plant | New Hampshire, USA | 414 MW Capacity

Newington is a gas-fired power plant located in Newington, New Hampshire, United States. With a capacity of 414 megawatts, it operates as a medium-scale facility within the US power generation sector. The plant is owned and operated by Granite Shore Power and is currently in operational status. The plant utilizes natural gas as its primary fuel, a cleaner-burning fossil fuel compared to coal. It operates under the regulatory framework of the US Environmental Protection Agency, including the Clean Air Act, National Ambient Air Quality Standards (NAAQS), and the Cross-State Air Pollution Rule (CSAPR). These regulations govern emissions of sulfur dioxide, nitrogen oxides, and other pollutants to protect air quality. Newington plays a role in meeting the electricity demands of the New England region. Its gas-fired technology offers flexibility and lower carbon intensity relative to older coal plants. The facility contributes to grid reliability and supports the integration of renewable energy sources through its dispatchable generation capacity.

The plant's gas-fired technology produces lower CO2, SOx, and NOx emissions compared to coal-fired plants, but still contributes to greenhouse gas emissions. Its location in New Hampshire, a state with growing renewable energy targets, places it in a transitioning energy landscape. The facility's proximity to populated areas may raise local air quality considerations, though modern gas plants typically employ emissions control technologies to meet EPA standards.
