Byron, Dresden, Quad Cities fail to clear in PJM capacity auction

Three Illinois nuclear power plants—Byron, Dresden, and Quad Cities—did not clear in last week’s long-delayed PJM Interconnection capacity auction, Exelon Generation reported in a filing with the Securities and Exchange Commission.

The news is likely to further pressure the Illinois General Assembly to pass a comprehensive energy package—one with subsidies for the state’s financially ailing nuclear plants—before Exelon moves forward with its plan, announced last August, to prematurely retire Byron and Dresden.

ANS, others throw weight behind bill to aid troubled Illinois nuclear plants

A large group of nuclear and nuclear-friendly organizations, including the American Nuclear Society, sent a letter on May 24 to Illinois lawmakers urging them to pass the Climate Union Jobs Act (CUJA) before the legislature adjourns at the end of this month.

Among its provisions, the bill would create 74 million megawatt-hours of carbon mitigation credits for Exelon’s Braidwood, Byron, Dresden, and LaSalle nuclear plants. The Clinton and Quad Cities plants, which participate in Illinois’s zero-emission credit program, would not be eligible. (In August of last year, Exelon Generation, owner and operator of all six nuclear plants in Illinois, announced that it would close Byron and Dresden without state support of some kind, adding that Braidwood and LaSalle were also imperiled.)

NYISO issues 2021 power trends report

The above figure provides NYISO's projected mix of resource capacity expected to be available for the 2021 Summer Capability Period. The figure below shows the vast difference in 2020 between clean energy provided to upstate New York and to downstate New York. With the recent closure of Indian Point-3, the difference will widen for downstate New York in 2021.

NYISO released its 2021 power trends report for the state of New York. As noted by many in the energy community prior to the closure of Indian Point nuclear power plant's Unit 2 and Unit 3 in 2020 and 2021, respectively, the projected mix of resource capacity expected for downstate New York's energy generation will be heavily reliant on fossil fuels.

Illinois governor backs limited aid to two nuclear plants

May 4, 2021, 9:30AMNuclear News


The office of Illinois governor J. B. Pritzker last week unveiled an ambitious energy plan for the state that includes limited subsidies for the financially ailing Byron and Dresden nuclear plants. (In August 2020, Exelon Generation announced that the two Illinois facilities would close this year—Byron in September and Dresden in November—without some form of compensation from the state, due to “market rules that favor polluting power plants over carbon-free nuclear energy.”)

The new plan, dubbed the Consumers and Climate First Act, calls for achieving 100 percent clean energy generation in Illinois by 2050 and recognizes nuclear as a means toward that end. “In the near term, the closure of nuclear plants in Illinois is likely to result in a generation gap that will be filled by dirty energy, namely fossil fuels,” the act states, adding that any support for nuclear should be “short-term and based on clearly demonstrated need.”

Indian Point closes today, ending some 60 years of clean power generation

The disturbingly long list of U.S. nuclear plants prematurely closed in recent years will get even longer tonight when the last reactor at the Indian Point Energy Center, Unit 3, powers down for the final time. The shutdown, scheduled for 11 p.m. local time, will mark the end of nearly 60 years of zero-carbon electricity generation at the Buchanan, N.Y., facility.

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?

A group of Illinois lawmakers joined Joe Duffy, executive director of the labor coalition Climate Jobs Illinois (CJI), at a virtual news conference on March 29 to unveil a union-focused, clean energy legislative proposal that includes help for the state’s struggling nuclear power plants.

Exelon touts reliability of Illinois nuclear plants

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.

Illinois plants set outage performance marks

May 11, 2020, 3:19PMNuclear News

Four of six Illinois nuclear power plants—Braidwood, Byron, LaSalle, and Quad Cities—set operational records while conducting spring refueling outages amid the COVID-19 pandemic.

Performance records include the shortest refueling outage (18 days) at LaSalle; the shortest refueling outage at Quad Cities (16 days), as well as the completion of the site’s longest continuous run (722 days); and the completion at both Braidwood and Byron of their sixth consecutive continuous cycle of operations, also known as a “breaker-to-breaker” run, according to a May 7 press release from Exelon Generation. Exelon’s average outage duration in Illinois this spring was 17 days, a full two weeks shorter than the national average, the release stated.
