General James M. Gavin Power Plant, a 2.6-Gigawatt coal-fired power station in Cheshire. The plant is operated by American Electric Power and is the largest coal fired power facility in Ohio, and one of the largest in the nation. Its two units, rated at 1300 MWe each, were launched into service in 1974 and 1975.[1] The plant is located 2.5 km (1.6 mi) upstream along the Ohio River from a smaller, older coal-fired Kyger Creek Power Plant..
