Constellation Completes Acquisition of Calpine
LCG, January 7, 2026--Constellation today announced that it completed its acquisition of Calpine Corporation from Energy Capital Partners (ECP). Constellation is now the largest producer of electricity in the U.S., with electric generation facilities across the nation.
Constellation states that its new generation portfolio will combine Constellation's zero-emission nuclear fleet with Calpine's extensive, low-emission natural gas fleet and zero-emission geothermal power, which will deliver reliable, clean power to about 2.5 million retail and business customers across America. The capacity of the combined portfolio is approximately 55,000 MW.
By acquiring Calpine, Constellation's footprint is improved in high-demand regions, especially in Texas and California, with continued significant operations in Illinois, Maryland, New York and Pennsylvania.
Constellation states that it plans to leverage this generation platform and its company cultures of safety and operational excellence to scale up new, clean technologies, including: advanced nuclear, geothermal, carbon capture and sequestration (CCS), and long-duration storage.
Constellation's president and CEO stated, "This isn't just about two great companies coming together – it's about strengthening America's future. Constellation is stepping up to power America's growth when our nation's demand for energy is surging, and our global competitors are racing to capture AI leadership. By uniting Constellation and Calpine, we're providing the reliable, clean energy that keeps our communities strong, our businesses competitive and our nation secure."
Calpine's president and CEO said, "This is an exciting day for both our companies and for the customers and communities we serve. We have the assets that power America today and meet the needs of tomorrow. Our expanded capabilities will allow us to better serve customers and communities, enable investment in critical infrastructure and support national priorities for energy security, economic competitiveness and technological leadership. Our teams share a relentless commitment to safety, sustainability and operational excellence, and I'm excited about what we will accomplish together."
"As a decades-long investor in power generation, ECP aims to unlock value, drive long-term growth opportunities and strengthen asset reliability – often serving as a bridge between public and private markets," said ECP's president and managing partner. "We are proud to have achieved those goals in partnership with Calpine's management team and believe this combination validates that vision, setting the company up for future success while meeting the evolving needs of its customers, communities and the U.S.'s electrical grid."
Back in December 2025, Constellation announced it had reached a resolution with the U.S. Department of Justice (DOJ) on the conditions required to complete the Calpine acquisition. This resolution was the final regulatory clearance needed to complete the transaction. As part of the DOJ resolution, the company agreed to divest York 2, a 828-MW natural gas-fired, combined-cycle plant in Pennsylvania, as well as the Jack Fusco Energy Center, a 605-MW natural gas fired combined cycle facility located outside Houston, Texas, and a minority ownership interest in the Gregory Power Plant, a 385-MW natural gas fired combined cycle near Corpus Christi, Texas. The Federal Energy Regulatory Commission (FERC) had approved the transaction conditioned on the divestiture of four of Calpine’s generating assets in the Mid-Atlantic region: Hay Road, Edge Moor, Bethlehem, and York 1.
