Constellation and Google Announce Strategic Collaboration that Includes 890 MW of New Nuclear Capacity to PJM Grid

LCG, October 6, 2026--Google and Constellation Energy today announced a long-term strategic clean energy collaboration to bring 890 MW of new, reliable, carbon-free nuclear capacity onto the PJM Interconnection grid to meet growing demand and increase grid reliability. The first uprate is expected to be delivered by 2028.

Department of Energy Announces $4.2 Billion Investment to Boost Nuclear Power in Pennsylvania and Ohio

LCG, October 5, 2026--The U.S. Department of Energy’s (DOE) Office of Energy Dominance Financing (EDF) today announced a conditional loan commitment of up to $4.2 billion to finance nuclear uprates and modernization across Vistra’s nuclear fleet in Pennsylvania and Ohio. The projects are expected to preserve nearly 4 GW of carbon-free, baseload power and add 433 MW of new nuclear capacity that will support the growing electricity demand across the PJM region.

Byron 2 Nuke Refuels in 16 Days, Limerick 2 in 17

LCG, April 24, 2001No one, it seems, knows how to operate nuclear power plants like former submarine commanders. Operators of two Exelon Corp. reactors turned in stunning refueling outages and returned to service over the weekend, the company said yesterday.

The 1,200 megawatt Byron Unit 2 pressurized water reactor near Rockford, Ill. returned to service on Sunday after completing a refueling outage in just 15 days, 18 hours, the quickest such outage in the history of U.S. commercial nuclear energy. During those 16 days, workers also found time to complete modifications increasing the reactor's output by 5 percent, in addition to performing thousands of maintenance and inspection functions.

The 1,200 megawatt Limerick Unit 2 boiling water reactor northwest of Philadelphia was back on line late Friday after completing a refueling outage of its own in just 16 days, 8 hours. That was the fastest-ever refueling for a boiling water reactor in the U.S.

"Exelon Nuclear intends to do its part to keep the lights on this summer," said Oliver D. KingsleyJr., president and chief nuclear officer of Exelon Nuclear. "These nuclear plants are particularlyreliable in the kinds of weather extremes that we sometimes see in the Midwest and mid-Atlanticregions in the summer."

Kingsley, who came to Exelon in the merger between Peco Energy Co. and Unicom Corp., had taken over nuclear operations for Unicom's Commonwealth Edison Co. subsidiary in 1997, when that utility's nuclear program was in a shambles. He quickly turned it around, and ComEd began generating more electricity than ever, with two fewer reactors.

Kingsley is a former U.S. Navy submarine commander. So is his boss, Exelon co-chief executive Corbin A. McNeill Jr., who had shaped up the nuclear program with Peco.
