IER recently released a first-of-its-kind study on the cost of electricity from the existing generation fleet, titled “The Levelized Cost of Electricity from Existing Generation Resources.” A major takeaway from the study is that the cost of electricity from new wind resources is three times more expensive than electricity from existing nuclear, hydroelectric, and coal power plants. Power from new combined cycle natural gas plants—the lowest-cost new source of electricity—is about twice as expensive as existing coal-fired electricity.
