GREC - Grand River Energy Center Gas Power Plant, Oklahoma, United States

GREC (Grand River Energy Center) is a natural gas-fired power plant located in Oklahoma, United States, with a capacity of 1,734.3 MW. It is owned and operated by the Grand River Dam Authority, a state-owned utility serving northeastern Oklahoma. The plant plays a significant role in the region's power generation mix, providing baseload and peaking capacity. The facility operates under the regulatory framework of the US Environmental Protection Agency, including the Clean Air Act and its associated programs such as the Acid Rain Program and the Cross-State Air Pollution Rule. As a gas-fired plant, it benefits from lower emissions of sulfur dioxide and nitrogen oxides compared to coal-fired units, though it still contributes to carbon dioxide emissions. The plant's technology is typical for modern gas plants, likely utilizing combined cycle or simple cycle turbines. GREC is strategically located near the Grand River and serves as a key asset for the Grand River Dam Authority's grid reliability. Its large capacity supports industrial, commercial, and residential customers in the region. The plant's environmental footprint is managed through compliance with state and federal regulations, and its gas fuel source aligns with the broader trend toward cleaner energy in the US power sector.

As a gas-fired power plant, GREC emits carbon dioxide, nitrogen oxides, and trace amounts of sulfur dioxide. Its location in Oklahoma, a state with significant oil and gas production, means the plant benefits from local fuel supply. The facility's emissions are regulated under the Clean Air Act, and its proximity to populated areas may require additional controls to meet air quality standards. The plant's large capacity contributes to regional greenhouse gas emissions, but gas-fired generation is generally less carbon-intensive than coal.
