Nuclear & Coal Will Account for Majority of U.S. Generating Capacity Retirements in 2021.
According to the U.S. Energy Information Administration’s (EIA) latest inventory of electric generators, 9.1 gigawatts (GW) of electric generating capacity is scheduled to retire in 2021. Nuclear generating capacity will account for the largest share of total capacity retirements (56%), followed by coal (30%).
Nuclear. At 5.1 GW, nuclear capacity retirements represent half of all total expected retirements in 2021 and 5% of the current operating U.S. nuclear generating capacity. The Exelon Corporation is scheduled to retire two of its Illinois nuclear plants, Dresden and Byron. Each of these plants has two reactors, and their total combined capacity is 4.1 GW. The Unit 3 (1.0 GW) reactor at Indian Point nuclear power plant in New York state is scheduled to retire in April. If all five reactors close as scheduled, 2021 will set a record for the most annual nuclear capacity retirements ever. The decrease of U.S. nuclear power generating capacity is a result of historically low natural gas prices, limited growth in electricity demand, and increasing competition from renewable energy.

Din förklaring är dock inte hela sanningen.
Despite being among the most efficient and reliable units in the nation’s nuclear fleet, Dresden and Byron face revenue shortfalls in the hundreds of millions of dollars because of declining energy prices and market rules that allow fossil fuel plants to underbid clean resources in the PJM capacity auction, even though there is broad public support for sustaining and expanding clean energy resources to address the climate crisis. The plants’ economic challenges are further exacerbated by a recent FERC ruling that undermines longstanding state clean energy programs and gives an additional competitive advantage to polluting energy sources in the auction.

Hade de haft en marknad som prioriterat att minska utsläppen hade de ju givetvis avvecklat det fossila innan kärnkraften.
