Constellation’s @GraceMVanderhei visited our Conowingo Hydroelectric Dam to offer a closer look at the people, the technology and the fish powering Maryland’s largest source of renewable energy. Full segment ↙️ bit.ly/3QQ8FIu 🎥 @ksensenig

Pleased to welcome @Interior @SecretaryBurgum to the Crane Clean Energy Center for a behind the scenes look at our work to restart the plant in 2027 and bring 835 MW of reliable energy back to the grid. We thank the Administration for its support of this project.

During our planned nuclear outages, we replace spent fuel with new fuel – one of the most important tasks in a plant’s lifecycle. Recently, at Braidwood Clean Energy Center in IL, technical experts removed the reactor head to access the core and carefully swap fuel assemblies.

We’ve earned the #1 spot on @barronsonline list of the Most Sustainable U.S. Companies. Sustainability is central to who we are, and this honor affirms how clean energy leadership and a commitment to reliable operations go hand-in-hand in support of our customers and communities.

Behind-the-scenes look at the turbine replacement work during Byron Clean Energy Center’s recent refueling and maintenance outage. Part of the $800M investment at our Byron and Braidwood sites in Illinois to add approximately 158 MW of reliable, emissions-free power to the grid.

Celebrated the completion of the 105 MW Pastoria Solar Project with leaders from @CA_DWR, labor partners and local officials. DWR’s largest renewable purchase to date supports decarbonizing ops by 2035 while reliably supplying water to 27M Californians. 📰bit.ly/3OoGC22

It’s go-time for the $800M we’re pumping into Byron and Braidwood Clean Energy Centers to add a total of ~158 MW of reliable, emissions-free nuclear power to the grid. Our Generation leaders checked in from Byron on the work underway.

Continued investment in our nuclear fleet preserves thousands of megawatts of existing reliable, emissions-free power. Constellation Chief Generation Officer Bryan Hanson illustrates how these units are built and maintained for the long haul.

The energy landscape doesn’t stand still – and neither will Constellation. Our strategy is designed to be nimble, respond to the needs of our customers and communities and ensure we’re always positioned to best support America’s energy future.

At #CERAWeek, Constellation CEO Joe Dominguez details how the energy industry is now grasping that effectively managing load from AI hyperscalers during periods of peak demand will lower costs for energy consumers across the board. Full conversation ↙️ bit.ly/40SM6EW

Speaking with @BloombergTV at @CERAWeek, Constellation President & CEO Joe Dominguez explains how long-term deals to power the data center economy support investments in reliability and added capacity across our nuclear fleet. Full interview ↙️ 📺 bloom.bg/4d7nm38

We’re among the leading energy companies teaming up with @nvidia and @EmeraldAi_ to power and advance a new class of AI factories that operate as flexible energy assets and can better support the grid during periods of peak demand. wsj.com/tech/ai/nvidia…

Joseph Dominguez (@ConstellationEG) and Atul Arya (@SPGlobal) discussed how to meet surging power demand while maintaining reliability and keeping electricity affordable at #CERAWeek.

Constellation leaders are gearing up to help drive the conversation at #CERAWeek on how smart generation investments and the right policy solutions will position the U.S. to meet rising energy demand and win the AI race without burdening families and businesses. @SPGlobal

For the fourth consecutive year, we’ve earned a place on @Just Capital and @CNBC’s list of America’s Top 100 public companies for responsible leadership. We’ve also secured the No. 1 spot for the “Utilities” sector! Learn more ↙️ justcapital.com/rankings/

Brand new 151-ton transformer is installed during Calvert Cliffs Clean Energy Center Unit 1’s planned refueling outage. Among the thousands of tasks scheduled to help Calvert – Maryland’s largest energy producer – generate enough reliable, clean electricity to power 1.3M homes.

The Constellation name is now shining bright at the Conowingo Dam – Maryland’s largest renewable energy resource. The new sign symbolizes our renewed commitment to the hydroelectric plant, which powers 165,000 homes and prevents 867,000 metric tons of carbon emissions annually.

We’re donating $150,000 to TradesFutures, a nonprofit established in part by @NABTU that expands pathways into union construction apprenticeships and careers. The skilled trades play a critical role in our ability to maintain and expand our nuclear fleet. constellationenergy.com/news/2026/02/t…
