The Eastern U.S. could be bracing for bigger summer electricity bills as power plant closures due to a host of federal emission regulations kick into high gear, according to energy market analysts.
Market analysts with Louisville, Ky., company Genscape confirmed this week that nearly eight gigawatts of primarily coal-fired power went dark as of Tuesday in the largest electricity market in the country, PJM Interconnection. That is enough electricity to power between 5.9 million-7.8 million homes.
PJM Interconnection is the grid operator that runs the electric delivery system across most of the densely populated areas of the eastern United States. The Genscape update on the power plant closures confirmed that the plants that went offline May 31-June 1 were critical to providing power to the system last summer when electric demand for cooling was at its peak.
