Elk River Gas Power Plant | Minnesota Power Generation Facility

Elk River is a natural gas power plant located in Minnesota, United States, with a generating capacity of 191.3 megawatts. The facility is owned by Great River Energy, a generation and transmission cooperative serving member distribution cooperatives in Minnesota and Wisconsin. As a gas-fired plant, it plays a role in the regional power grid, providing flexible generation to complement renewable sources. The plant operates under the regulatory framework of the United States Environmental Protection Agency (EPA), including the Clean Air Act (CAA) and associated programs such as the National Ambient Air Quality Standards (NAAQS) and the Cross-State Air Pollution Rule (CSAPR). These regulations govern emissions of sulfur dioxide (SO2), nitrogen oxides (NOx), and other pollutants. Gas-fired plants like Elk River generally have lower emissions compared to coal-fired units, but still must comply with applicable standards. Elk River contributes to the energy needs of the Upper Midwest, supporting the reliability of the regional grid. Its location in Minnesota places it within a state that has a growing focus on renewable energy, and gas plants often serve as a backup for intermittent sources like wind and solar. The facility's operational status and capacity make it a relevant asset in the local power generation landscape.

As a gas-fired power plant, Elk River produces lower carbon dioxide (CO2) emissions per megawatt-hour compared to coal plants, but still contributes to greenhouse gas emissions. Its location in Minnesota, a state with increasing renewable energy targets, means the plant may operate as a peaking or intermediate unit, balancing grid stability. Proximity to populated areas could influence local air quality, though gas plants typically have lower SOx and NOx emissions. The facility's age and technology (subcritical vs. Modern gas plants often use combined cycle technology for higher efficiency.
