This was not an ordinary day in the office for Sr. EVP of Finance and Data Economy Dan Eggers. During Limerick Clean Energy Center’s recent refueling and maintenance outage, Dan took on an unforgettable challenge – climbing Unit 1’s 522-foot nuclear cooling tower. The experience offered a one-of-a-kind view and an even greater appreciation for the scale of the assets we operate and the world-class teams who keep them running. From bottom to top, the ascent was a powerful reminder: it takes extraordinary people to reliably power everyday life.

For 25 years, Constellation’s Fishing for a Cure tournament has brought the community surrounding our Braidwood Clean Energy Center together to make a difference, and 2026 was no exception. This year’s event raised more than $90,000 for nonprofit Project Fire Buddies, a local group of firefighters that uplift children battling critical illnesses by visiting them in their homes, often with a parade of firefighting vehicles.

“I’m humbled by the support shown by Constellation and its employees,” said Kurt DeGroot, CEO and Founder of Project Fire Buddies. “This is the largest donation we have ever received, and we are eager to put these funds to work brightening the lives of the children we serve.”

To date, Fishing for a Cure has raised more than $1.1 million for a range of causes in support of local families and children.

Constellation joined Governor Greg Abbott and state and local leaders in Fairfield, Texas, to mark the completion of the Pin Oak Creek Energy Center – a new 460 megawatt, state of the art natural gas peaking facility built to deliver firm, dispatchable power to the ERCOT grid. Designed to start up within minutes, Pin Oak Creek can respond quickly as demand and grid conditions change, providing critical support for families, businesses and critical infrastructure when reliability matters most. It’s also the first project to achieve commercial operation under the Texas Energy Fund, which was created to incentivize new dispatchable generation to meet the state’s growing economy and power demand.
