> U.S. coal power capacity peaked in 2011 at more than 317 gigawatts (GW), but steadily declined nearly 30% ever since, hitting a record high of 19.3 GW closed in 2015 and 13.1 GW closed in 2020. For context, coal’s share of U.S. electricity generation has plummeted from 50% a decade ago to less than 20% today.
> But the fundamental economic pressures pushing coal out of the U.S. electricity mix remain unchanged – 80% of existing coal plants across the country cost more to continue running than replacing them with new local wind or solar generation. Plant closure announcements have resumed their march to zero, with the U.S. Energy Information Administration (EIA) reporting 12.6 GW of coal capacity will close in 2022, representing 85% of all electric generation capacity retirements this year.
> Coal’s outlook is even more grim over the next several years. S&P Global Market Intelligence reports utilities will close 51 GW of coal power between 2022 and 2027, followed by a “record plunge” in 2028 with more than 23 GW scheduled closures. Federal rules to keep coal ash and toxic metals out of drinking water will take effect that year – regardless of Supreme Court decisions on the U.S. Environmental Protection Agency’s authority to regulate greenhouse gas emissions – and many utilities are not investing in compliance upgrades for plants that keep losing money.
