May 11, 2020· U.S. coal-fired capacity peaked at 318 gigawatts (GW) in 2011 and has been declining since then because many plants retired or switched to other fuels and few new coal-fired plants came online. By the end of 2019, U.S. coal-generating capacity totaled 229 GW. The coal fleet's rate of operation, or utilization, has also decreased.
