“Keeping Illinois nuclear plants open is saving some customers $237 a year on average,” reads the headline of a recent CNBC article about the Climate and Equitable Jobs Act, which was passed by the Illinois legislature and signed into law by Gov. J.B. Pritzker in September 2021. The legislation includes a provision to keep Illinois nuclear power plants open to meet the state’s clean energy goals, even if the facilities are not profitable.

Oklahoma showing interest in nuclear

February 24, 2022, 7:01AMANS Nuclear Cafe

This year has been a good one so far regarding interest from state legislatures in the potential of nuclear energy. Examples reported by Nuclear Newswire include, in January, an Indiana bill to incentivize the construction of small modular reactors, and this month, West Virginia’s repeal of its ban on new nuclear plant construction and legislation in Illinois aimed at achieving the same end in that state. Slipping under our radar until now, however, is a measure in Oklahoma introduced earlier this month that would create a feasibility study to examine the possibility of nuclear power in the Sooner State.

Byron, Dresden saved by the bill? An update

(This story has been updated from yesterday's post about the Illinois energy package.)

With only days remaining before the scheduled retirement of Exelon Generation’s Byron nuclear plant, the Illinois House has approved a comprehensive energy package (S.B. 2408) that would save the plant, as well as the state’s similarly struggling Braidwood and Dresden facilities.

A tale of three states

Stories are unfolding (or have unfolded) in three of our key states that illustrate the challenges facing the backbone of our country’s clean, reliable electricity generation infrastructure. I write, of course, about existing nuclear power plants. On the East Coast, New York is a done deal. Indian Point-3 shut down on April 30. The state authorities are banking on offshore wind to pick up the slack. They shrug off the cost and intermittency challenges associated with deploying wind power. We’ll see.

No deal yet in Illinois for Exelon nuclear plants

The Illinois Senate adjourned on June 15 without calling a comprehensive energy regulatory reform package for a vote, Capitol News Illinois reported. State Sen. Bill Cunningham (D., Chicago) and Senate president Don Harmon (D., Oak Park) said afterward that they expect a vote to happen sometime this summer as negotiations continue.

A state of uncertainty: Nuclear power in Illinois

April 30, 2021, 5:01AMNuclear NewsMichael McQueen

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?

Illinois AFL-CIO releases updated nuclear impacts report

In response to Exelon’s announcement of the premature closure of two Illinois nuclear power plants—Byron and Dresden—the Illinois AFL-CIO released an updated version of the Brattle Group’s Illinois Nuclear Impacts Report.

The report highlights the economic losses and environmental impacts Illinois’ and its local communities will face with the retirement of these plants, according to a January 5 article posted to the 23WIFR website.

Exelon CEO urges Illinois legislators to save nuclear plants

Christopher Crane, president and chief executive officer of Exelon, wrote in a Chicago Sun-Times op-ed, “The failure of national energy markets to support clean energy will soon force the premature retirement of two of [Illinois’s] six zero-carbon nuclear plants, putting thousands of people out of work, raising energy costs, and taking us decades backward in the fight against climate change."

Crane urged Illinois policymakers to act quickly, as they face critical decisions about the future of energy that will affect the state’s environment, the economy, and the health of every family for years to come.

Local pol goes digital to save Illinois nuclear plant

October 14, 2020, 9:46AMNuclear News


Illinois State Representative Tom Demmer (R., Dixon) announced last week the creation of a website,, devoted to preventing the early closure of Exelon Generation’s Byron nuclear power plant.

According to the October 9 announcement, Demmer began working with the city of Byron, Ill.-based Wave Marketing to create the website following Exelon’s August decision to prematurely retire both the Byron plant and the Dresden nuclear plant, located in Morris, Ill., absent state legislation to aid the financially troubled facilities. Byron’s two pressurized water reactors are currently slated to cease operation in September of next year, followed in November by Dresden’s two boiling water reactors.

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.
