ECP and KKR Launch 190 MW Data Center in Bosque County

Energy Capital Partners and KKR announced on July 30, 2025, the joint development of a 190 MW hyperscale data center campus in Bosque County, Texas — the first investment under their $50 billion strategic partnership targeting AI infrastructure. Calpine will supply dedicated power from its adjacent Thad Hill natural gas plant under a long-term contract, eliminating dependence on grid interconnection queues.

What Is Being Built

The multiphase campus is developed with data center operator CyrusOne and will cover more than 700,000 square feet with initial IT capacity of 144 MW, scaling to a total of 190 MW. Total investment is expected to approach $4 billion. The site sits on land adjacent to Calpine’s Thad Hill Energy Center — a co-location that delivers power at the fence line with no long-distance transmission requirement. Calpine executed a dedicated long-term supply contract and will redirect surplus capacity to support ERCOT reliability during scarcity events. An undisclosed tech company has leased the facility. Operations are targeted for Q4 2026.

Critical Perspective

A 190 MW off-grid data center co-located with a dedicated natural gas plant is rational engineering, but the announcement declines to disclose the contract term between ECP, KKR, and Calpine — the single most important variable for counterparty risk. Data center demand has historically over-forecast by 20-40% in speculative AI buildout cycles; the 2015-2018 cloud buildout left 15% of Tier III Texas capacity uncontracted for 36 months post-commissioning. The $4 billion investment implies roughly $21/W of data center capacity — a figure that makes sense only if Bosque County facility utilization exceeds 85% for the contract duration. The question nobody is asking: if the Stargate AI demand thesis revises downward by 2028, does 190 MW of stranded natural gas generation in Bosque County become a grid liability or a county revenue shortfall?

Why It Matters

The Bosque County campus represents a structural shift in how hyperscale AI facilities secure power. Rather than queuing for utility interconnection — a process that routinely exceeds three years in ERCOT and other markets — ECP and KKR co-located directly with a generation asset and structured the deal so the facility provides dispatchable demand during grid scarcity. ERCOT’s deregulated market enables direct supply agreements that utility-regulated states cannot easily replicate, which is why Texas has become the primary U.S. market for this model. The ECP–KKR partnership plans to replicate this approach nationally through their $50 billion commitment. Bosque County is the first deployment; additional campuses are expected as the model proves out operationally in 2026.
