Gavin Power Plant

General James M. Gavin Power Plant is a 2.6-gigawatt (2,600 MW) supercritical coal-fired power station in the village of Cheshire, Ohio, United States. It is owned by Lightstone Generation LLC, a 50–50 joint venture of The Blackstone Group LP and ArcLight Capital Partners. Gavin is the largest coal-fired power facility in Ohio, and one of the largest in the nation, capable of powering two million homes. In February 2017, the plant represented slightly more than 11 percent of the total electric generation capacity in Ohio.Gavin's two units, rated at 1,300 MW each, were placed into service in 1974 and 1975. The power plant is connected to the electric transmission grid by 765-kilovolt transmission lines. The plant contributes approximately $6 million a year in property taxes that support the Gallia County school system and government. The plant is Gallia County's largest taxpayer and makes annual contributions of more than $50,000 to local charities and non-profits.Gavin is equipped with a suite of air quality controls. These include selective catalytic reduction units that reduce nitrogen oxide emissions by 82 percent; flue-gas desulfurization units (scrubbers) that remove 94 percent of sulfur dioxide emissions and electrostatic precipitators for particulate control. Together the controls reduce mercury emissions by up to 91 percent and particulates by 99 percent.
