Independent power companies are building or planning to build at least six natural-gas-fired power plants in Ohio, in hopes of replacing old coal-fired plants being closed by utility companies, reports. The independent companies “hope to capitalize on Ohio’s plentiful and cheap shale gas,” as well as the closures of coal-fired plants and proposed federal regulations to reduce carbon dioxide emissions. The natural gas plants differ from conventional coal-burning plants in that they “combine gas turbines and steam boilers, making them far more efficient.” The drawback to the plants is that gas cannot be stored onsite as coal is, so they are vulnerable to pipeline disruptions. Ohio regulators recently said “they expect 4,300 megawatts of electricity to flow from new gas-fired power plants by 2019, most of it from plants owned by independent power companies.” Among the new plants being planned or built are the Carroll County 750-megawatt plant (see our April 10, 2015 blog post for more on this) as well as plants near Toledo, Middletown, and Trumbull County.
