U.S. power providers will close more coal-fired generation capacity in 2018 than any year before, according to research released last week by the Institute for Energy Economics and Financial Analysis (IEEFA), a clean energy think tank.
The U.S. will retire 15.4 GW of coal capacity this year, IEEFA reported, representing 44 generation units across 22 plants. By 2024, an additional 21.4 GW of coal capacity will go offline, and that number will likely rise as generators announce more retirements.
IEEFA expects the 2018 retirements to "easily" surpass the current record of 14.7 GW of coal retirements, set in 2015. The U.S. still has 246 GW of coal capacity online, and announced retirements through 2024 represent about 15% of that operating fleet.
