99% of U.S. Coal Plants Cost More to Run Than Replace With New Renewables, Study Finds
According to recent research by Energy Innovation, it would be less expensive to construct new renewable energy capacity than to continue running the vast majority of current coal plants in the United States. More than 99% of the country's remaining 210 coal-fired power facilities cost more to operate than it would cost to replace them with new renewable energy, up from 62% in 2019. The national median cost of current coal electricity is $36/mW-h, whereas new solar costs just $24/mWh. Wyoming's Dry Fork Station, the sole cost-competitive coal station in operation when compared to developing new renewables, is just $0.32/mW-h cheaper.
