Constellation Energy Corporation and CyrusOne expanded their Texas data center power partnership with a new agreement supporting a large-scale facility adjacent to the Freestone Energy Center. Under the deal, Calpine LLC will provide 380 MW of power, grid connectivity, and site infrastructure for CyrusOne’s new development in Freestone County, roughly 80 miles (129 km) southeast of Dallas.
The agreement also includes an exclusive option for a second 380 MW phase at the same site. Combined with a previously announced 400 MW arrangement at the Thad Hill Energy Center in Bosque County, CyrusOne now has more than 1,100 MW of contracted power capacity tied to Constellation-owned generation assets in Texas. The structure is designed to support rapid data center deployment while maintaining grid reliability for other regional customers.
Constellation said the project leverages its “Powered Land Capabilities,” which pair generation, land, and grid access to support large-load customers such as hyperscale and AI-driven data centers. CyrusOne said the partnership strengthens its ability to meet growing customer demand in Texas while ensuring reliable power delivery for surrounding communities.
- 380 MW initial power and infrastructure agreement at the Freestone Energy Center site
- Exclusive option for an additional 380 MW Phase 2 at the same location
- More than 1,100 MW now under contract between Constellation/Calpine and CyrusOne in Texas
- Builds on a prior 400 MW agreement at the Thad Hill Energy Center
- Focus on speed-to-market, predictability, and grid reliability for large-scale data centers
Joe Dominguez, president and CEO of Constellation, said the agreement “demonstrates Constellation’s ability to meet the growing demand from the data economy while maintaining grid reliability… helping lay the foundation that will keep America at the forefront of AI and digital technology.”
🌐 Analysis
The deal reflects a broader trend of data center operators securing power through direct relationships with generation owners to de-risk interconnection timelines and capacity constraints in high-growth markets like Texas. For Constellation and Calpine, these agreements extend a growing portfolio of large-load, behind-the-meter or adjacent-to-generation projects, while competitors across the power and infrastructure sector pursue similar models to serve AI-driven data center demand.
