Exelon Generation announced it intends to retire its Byron and Dresden nuclear power stations in Illinois next year 2021, resulting in the loss of four nuclear reactors with 4,333 MW of gross stalled capacity – enough to supply energy to more than four million homes and businesses.
The two units at Dresden are licensed to operate for another decade and two units at Byron for another 20 years. However, Byron now will close in September 2021 and Dresden in November 2021.
