On a quiet patch of Bosque County near Whitney, where traffic usually means lake-goers and farm trucks, data center giant CyrusOne is lining up a build-out that looks more like something you would expect off a Dallas freeway. New state filings point to several huge single-story data buildings, stacked project budgets in the hundreds of millions, and a direct tie-in to a nearby natural gas plant that is designed to feed hyperscale computing customers as quickly as regulators allow.
Filings outline three new buildings, big checks and multi-year work
According to Data Center Dynamics, CyrusOne's latest paperwork lists three projects, labeled DFW17, DFW17B and DFW17C. All are single-story, ranging from roughly 88,875 square feet to about 249,090 square feet, with estimated budgets of around $375 million, $500 million and $430 million, respectively. The filings map construction windows across 2025 through 2027 and show that CyrusOne plans to stage fit-outs across the wider campus rather than flip everything on at once.
The Houston Chronicle points to a Texas Department of Licensing and Regulation filing that pins the Whitney project at FM 56 and County Road 3610A and records a petition lodged on December 5, underscoring that this is no longer just an early concept.
Power deal cranks site capacity toward 400 MW
The hardware is only half the story. CyrusOne has also locked in a dedicated power arrangement with Calpine that effectively turns the nearby Thad Hill Energy Center into the campus's personal muscle. The companies say their Powered Land agreement was expanded to provide a total of 400 megawatts to the Whitney site.
CyrusOne said the second phase of the deal added 210 megawatts on top of an earlier 190 megawatt commitment. Chief executive Eric Schwartz cast the arrangement as a way to, in his words, "enable a comprehensive solution for power, grid connectivity and site infrastructure," a neat summary of why data center builders like to hug power plants.
Whitney campus plugs into a bigger Bosque County push
The Whitney development is not happening in isolation. Energy Capital Partners and KKR have announced a joint project in Bosque County that aims to deliver a multiphase hyperscale campus with total investment that could run from the high hundreds of millions into the billions.
BusinessWire describes plans for more than 700,000 square feet of build-out and an initial IT load of roughly 144 megawatts. Industry filings show that CyrusOne previously filed DFW10 and DFW11 applications tied to the same Whitney location, and Data Center Dynamics reported the company's estimate that the full campus could ultimately reach around 400 megawatts at complete build-out.
Locals eye power, water and ERCOT strain
All that capacity on rural land has not gone unnoticed. Regional outlets and energy reporters say the hyperscale rush is already drawing questions about how much electricity and water this kind of project will need, and who absorbs the risk if the grid feels the pinch.
The Dallas Morning News and other publications have highlighted concerns from residents and lawmakers about the strain large data centers can place on ERCOT and local resources once developers lock in long-term power deals.
Industry records identify Calpine's Thad Hill Energy Center, which sits adjacent to the CyrusOne parcels, as a natural gas combined cycle plant with a roughly 250 megawatt nameplate block. State inspection data puts the facility at 557 County Road 3610 in Clifton. Technical details are laid out in Power Engineering coverage, while permitting and boiler records appear in Texas Department of Licensing and Regulation files.
What the timeline looks like and signs to watch
Public filings and company comments now put the newest Whitney buildings on a 2026 to 2027 construction timetable, with CyrusOne signaling it will bring capacity online in phases over several years as approvals and interior fit-outs fall into place. That sits on top of the broader 2025 to 2027 construction windows listed in state paperwork for the current round of projects.
The Houston Chronicle notes the December 5 filing and the build windows regulators have posted. For locals trying to gauge when this turns from paper plans into dust and concrete, the clearest signs will likely show up in Bosque County permitting dockets, new entries in Texas Department of Licensing and Regulation databases and fresh notices from the company itself as crews line up to move dirt.
