Constellation Energy signed new long-term power purchase agreements during the second quarter that will supply roughly 920 megawatts of nuclear generation to new customers, company executives said during a recent earnings call. The agreements run between 15 and 20 years and are set to begin service between 2029 and 2032. Most of the power, about 890 megawatts, will come from existing generation, while the remainder will be supported by a planned 30 megawatt uprate at the company's Dresden plant in Illinois.
Constellation president and CEO Joe Dominguez said data centers are driving demand for reliable power and that existing nuclear infrastructure will serve as the near term foundation for supplying them, since new plants take years to permit and build.
The restart of the former Three Mile Island Unit 1, now called the Crane Clean Energy Center in Pennsylvania, cleared two regulatory steps in the second quarter after the Nuclear Regulatory Commission approved a fuel license amendment and the Federal Energy Regulatory Commission approved a related waiver request. Dominguez said the approvals keep Crane on track to restart in the second half of 2027.
The company also highlighted subsequent license renewal filings covering two of its three nuclear plants in New York, including a June application for the Ginna plant. Constellation's nuclear fleet produced 44,160 gigawatt hours in the second quarter, achieving a 93 percent capacity factor, with 86 planned refueling outage days compared to 41 during the same period last year.
