Owner of Calvert Cliffs nuclear plant clashes with BGE, other Maryland utilities over data centers

Constellation Energy, the Baltimore-based owner of the Calvert Cliffs nuclear power plant in Southern Maryland, says it’s in talks with large technology companies that want to build data centers next to the facility and bypass the electric transmission grid. Advocates for building data centers in the state believe they will be a boon for the state economy, but Constellation’s plans put it at odds with its former corporate sibling Baltimore Gas and Electric Co., whose parent Exelon Corp. spun off the energy producing company in 2022.
