Constellation Energy has announced an agreement with Commonwealth Edison (ComEd), Illinois’s largest electric utility, to power the latter’s 54 offices and metered facilities with locally produced nuclear energy, 24/7.

A state of uncertainty: Nuclear power in Illinois

If there is one U.S. state you might think would be on top of the nuclear-plant-retirement problem, it’s Illinois: With 11 power reactors, more than any other state, it is number one in nuclear generating capacity. In 2019, 54 percent of its in-state generation came from nuclear power. So why, at this writing in mid-April, does Illinois still face the possibility of losing two of its nuclear plants later this year?

Despite current policy and economic challenges, nuclear’s future remains bright

Byron (left) and Dresden (right) may be looking at early retirement if Springfield doesn't pass an energy package before the fall of 2021.

On August 27, I stood in front of small groups of socially distanced employees at our Dresden Generating Station in Illinois, announcing plans for the premature retirement of the nuclear facility next fall. A hundred miles away, our chief operating officer was delivering a similar, equally somber announcement to employees at the Byron Station.

Despite being among the safest, most efficient, and reliable nuclear plants in the nation, 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 merchant nuclear 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.
