BALTIMORE and DALLAS (February 9, 2026) — Constellation (NASDAQ: CEG) announced today that Calpine LLC, a business unit of Constellation, signed a new 380-megawatt (MW) agreement with Dallas-based CyrusOne, a leading global data center developer and operator, to connect and serve a new data center adjacent to the Freestone Energy Center, in Freestone County, Texas.
The agreement provides CyrusOne with access to power, grid connectivity and site infrastructure needed to support development of the new facility, while ensuring electricity continues to flow to the regional grid and ensuring reliability for all customers and communities. Calpine has also entered into an exclusive agreement to provide power, grid connectivity and site infrastructure for Phase 2, which will be an additional 380 MW.
These agreements are in addition to the 400 MW agreements announced in the second half of last year between Calpine and CyrusOne for the Thad Hill Energy Center in Bosque County, Texas.
"This agreement reinforces CyrusOne's commitment to meeting customer demand in Texas," said Eric Schwartz, CEO of CyrusOne. "Partnering with Constellation and Calpine enables us to deliver reliable, scalable infrastructure while ensuring grid reliability for local communities."
The new facility will be located adjacent to Calpine’s existing Freestone Energy Center, which is located approximately 80 miles southeast of Dallas.
