Question · Q3 2025
Paul Zimbardo inquired about the generic opportunity for uprates, specifically referencing the 340 megawatts at Limerick and asking if more 'Limericks' exist. He also sought an update on the transmission interconnection process for Limerick, given public disclosures about a potential data center there. Additionally, he asked if future efforts would prioritize uprate sites due to their economic merits compared to new nuclear construction.
Answer
President and CEO Joe Dominguez clarified that Constellation has identified about 900-1,000 megawatts of uprates, with LaSalle and Limerick being large chunky ones, and Calvert Cliffs contributing 190 megawatts, all with completed engineering work. He noted strong demand in the Limerick area, making new megawatts there likely welcomed and easy to interconnect, but declined to comment on specific data center interconnections. Mr. Dominguez agreed on the economic merits of uprates, highlighting that they are great investments, additional, within Constellation's expertise, and do not add O&M or fuel costs, making their capital numbers very attractive compared to new plants. He emphasized that uprates are not binary to other initiatives and are a strong focus.
