Expected to be operational in Q4 2026
CyrusOne has signed a deal with US power producer Calpine Energy for 190MW of power for its planned data center in Bosque County, Texas.
The DFW10 data center will be located adjacent to the Calpine-owned Thad Hill Energy Center. Thad Hill is a natural gas power plant with a capacity of 250MW. It was commissioned back in 2010 and serves the Electricity Reliability Council of Texas (ERCOT) grid. Calpine is owned by a consortium of companies, led by Energy Capital Partners (ECP).
The agreement includes power supply from the facility, a firm grid connection, and land where the data center will be located. The campus is currently under construction and is expected to be operational in Q4 2026.
"This first-of-its-kind project establishes Calpine as a leader in reliable, scalable power solutions for hyperscale customers, leveraging our world-class fleet and Powered Land Capabilities along with a suite of products and services to support both customer needs and grid reliability across ERCOT and beyond,” said Rick Pena, EVP of Corporate Development at Calpine.
CyrusOne is the main developer of the project, with backing from investment firms Global Infrastructure Partners, a part of BlackRock, and KKR.
The data center will be constructed through a phased approach, with the facility’s first phase covering 190,000 sq ft (17,651 sqm), with a capacity of 144MW. Sources familiar with the deal told DCD that the second phase would expand the campus to more than 700,000 sq ft (65,032 sqm) and deliver an IT capacity of 288MW.
According to Calpine, its generation portfolio within ERCOT will have the capacity to deliver up to 400MW of power to data centers across Bosque.
Reports on the data center first emerged last November, following a filing to the Texas Department of Licensing and Regulation.
"We're proud to be part of this landmark project, which combines dedicated power and data center expertise to deliver a unique, mission-critical solution to our customers," said John Hatem, CEO at CyrusOne. "As AI drives unprecedented data demand, this campus demonstrates our commitment to delivering scalable, reliable infrastructure for our Intelliscale customers while supporting grid reliability for consumers and businesses in Texas and beyond."
According to the companies, the site is designed for rapid expansion and is expected to represent a total investment of up to $4 billion. The deal is the first through ECP’s and KKR’s $50bn strategic partnership to support AI infrastructure growth in the US. The partners see the facility acting as a blueprint for future deployments under the partnership.
“This first investment through our strategic partnership combines ECP’s power expertise to deliver reliable near-term power with KKR’s strong track record in investing in data center development,” said Tyler Reeder, president of ECP.
According to CyrusOne, the campus will have climate-neutral initiatives, water conservation, biodiversity protection, and capabilities to respond during ERCOT grid emergencies.
In January, Calpine was sold to Constellation Energy for $16.4bn. The agreement is expected to close within 12 months of the original announcement. When it closes, it will create the largest clean energy provider in the US market.
KKR-owned CyrusOne has more than 50 data centers across the US and European markets. In the Texas market, it has more than 14 data centers - both planned and operational - with more than half based around Dallas-Fort Worth.
Last September, the company filed to develop a data center dubbed DFW7 in Fort Worth. The facility is set to cost $200 million and span 1.9 million sq ft (176,000 sqm) across a one-story data center and two-story office component. Construction was slated to begin in October this year, with completion expected in Q1 2026.
It recently announced its entrance into the Asian market, breaking ground on its first data center project in Japan last September.
Last month, the company announced plans for a data center campus just outside London. The facility planned for Iver Heath, Buckinghamshire, is set to deliver 90MW of IT capacity.
