Exelon's Byron generating station in northern Illinois. The future of Byron is uncertain at this time and could impact the new power generation company, once it's formed.

Exelon Corporation announced yesterday that it intends to spin off Exelon Generation, its competitive power generation and customer-facing energy businesses, from Exelon Utilities, its group of six regulated electric and gas utilities.

The split into two publicly traded companies will “establish the nation’s largest fully regulated transmission and distribution utility company and the largest carbon-free power producer paired with the leading customer-facing platform for clean, sustainable energy solutions,” Exelon said in its February 24 announcement.

Amid all the talk of last week’s winter storm and the resultant grid debacle in Texas, Exelon on Monday issued a press release informing customers of just how reliably its Illinois nuclear power plants have been operating this winter.

The release might also be seen as a message to state lawmakers, who have yet to produce any legislation to aid the utility’s financially challenged nuclear facilities—of which two, Byron and Dresden, have been slated for retirement later this year, given the (so-far) absence of such legislation.

According to the U.S. Energy Information Administration’s latest inventory of electric generators, 9.1 gigawatts (GW) of electric generating capacity is scheduled to retire in 2021.

In total, it appears that 30 plants (nuclear, coal, petroleum, and others) will be retired in 2021. Five nuclear reactors are included in the closure list—Indian Point-3, Byron (two units at the plant), and Dresden (two units at the plant). Those three plants produce 5.1 GW of power, accounting for more than half of the total capacity expected to be retired.

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.

Crane

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.

Chesney

An Illinois lawmaker is hopeful that legislation is coming in the state that would benefit nuclear power plants. “I believe we’re going to have an incentive program that will be in partisan legislation,” said Andrew Chesney, Illinois state representative for the 89th District.

Although a much-discussed October 12 story from Bloomberg headlined “Exelon Weighs Shedding Nuclear Plants, Other Non-Utility Assets” went unconfirmed, a new report from Greentech Media says that confirmation has now taken place.

Demmer

Illinois State Representative Tom Demmer (R., Dixon) announced last week the creation of a website, savebyron.com, 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.

As a not-for-profit scientific and professional organization, the American Nuclear Society’s raison d’être has always been the advancement of nuclear science and technology. While many among our diverse ranks may see themselves as advocates, it is important to recognize that ANS the organization will never take the place of industry trade associations like the Nuclear Energy Institute or the U.S. Nuclear Infrastructure Council. No, we will always be dedicated first to serving the men and women of the nuclear community, both here in the United States and around the world, as a source of news, technical knowledge, professional development opportunities, and scientific fellowship.

This should not in any way dissuade us, however—either individually or as a community—from engaging in the public discussion about nuclear technology, especially when debates become tainted by outright falsehoods or “fake news.” As we have seen in stark relief over the past eight months of pandemic-dominated life, the scientific community has a societal obligation to stand up and set the record straight when misinformation crops up. Simply put, we have to be prepared to call balls and strikes.

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.

Lonnie Stephenson, international president of the International Brotherhood of Electrical Workers, wrote an op-ed published in the September 25 Chicago Sun-Times touting the benefits of nuclear power in Illinois and decrying Exelon’s plan to prematurely shutter the Byron and Dresden plants.

The flurry of public statements issued in reaction to last Thursday’s news regarding Exelon’s decision to prematurely retire its Byron and Dresden nuclear power plants includes one from an organization representing the North America’s Building Trades Unions (NABTU).

Exelon Generation, operator of the largest nuclear reactor fleet in the United States, intends to downsize that fleet next year by retiring its Byron and Dresden plants. In an announcement released early this morning, Exelon said that the two-unit Byron, located near Byron, Ill., would be permanently closed in September 2021, followed in November by the two-unit Dresden, located in Morris, Ill.

Byron is licensed to operate for another 20 years; Dresden, a much older facility, is licensed for another decade.
