George Johnson Gas Power Plant | Michigan, USA

George Johnson is a natural gas-fired power generation facility located in Michigan, United States. With a capacity of 51 MW, it falls within the small-to-medium scale for gas power plants. The plant is owned and operated by Wolverine Power Supply Coop, a cooperative utility serving member communities in the region. The facility operates under the regulatory framework of the U.S. Environmental Protection Agency (EPA), including the Clean Air Act (CAA) and associated programs such as the National Ambient Air Quality Standards (NAAQS) and the Acid Rain Program. As a gas-fired plant, it benefits from lower emissions of sulfur dioxide (SO2) and particulate matter compared to coal-fired units, though it still contributes to nitrogen oxide (NOx) and carbon dioxide (CO2) emissions. The plant's technology is typical for its size and era, likely utilizing simple-cycle or combined-cycle gas turbines. George Johnson plays a role in meeting local electricity demand, particularly during peak periods. Its cooperative ownership structure emphasizes reliability and community service. The plant's location in rural Michigan minimizes direct population exposure to emissions, though it still contributes to regional air quality and greenhouse gas inventories.

The plant's gas fuel type results in lower SOx and particulate emissions compared to coal, but NOx and CO2 emissions remain relevant. Its 51 MW capacity places it in a moderate scale band, with environmental impact proportional to its output. Proximity to populated areas is limited given its rural Michigan setting, reducing local health risks. Modern combined-cycle units achieve higher efficiency and lower emissions per MWh.
