Eight new natural gas-fired combined-cycle gas turbine (CCGT) power plants have come online or will come online in the United States this year. These new plants will add 7,775 megawatts (MW) of electric-generating capacity to the U.S. electric grid, based on our estimates and data from our latest Monthly Electric Generator Inventory. These eight projects reverse four years of decline in CCGT plant start-ups. We expect CCGT electric-generating capacity to reach almost 290 gigawatts (GW) by year end, or 24% of total U.S. generating capacity.
