Under the deal, finalized in late September between Anthropic's corporate leadership and OnePWR Solutions, the AI developer took over an equipment order queue that OnePWR had placed with heavy machinery manufacturer Caterpillar Inc. two years earlier.

Caterpillar's Manufacturing Slots Change Hands

By assuming those multi-year manufacturing slots, Anthropic sidesteps supply chain constraints that would otherwise delay access to heavy-duty generator hardware.

Rather than buying OnePWR outright or absorbing its staff, Anthropic acquired the underlying manufacturing queue rights, technical designs, and installation logistics needed to put the hardware in the field.

OnePWR Solutions, a San Antonio-based energy infrastructure provider, remains named alongside Caterpillar as the energy equipment supplier for the program, which is officially designated the Anthropic Off-Grid 1.7GW Power Generation & Data Center Initiative.

The transaction is the largest single purchase of power-generation equipment ever executed by an artificial intelligence firm, a reflection of the surging global demand for gigawatt-scale computing facilities.

Dedicated Capacity of 1.7 Gigawatts

The acquisition covers 1.7 gigawatts of heavy-duty, gas-fired generation equipment built around advanced natural gas generators designed for base-load and peak-shaving operations.

That generating capacity is intended to supply high-density server racks directly, delivering continuous, utility-scale electricity to off-grid campus locations.

The scope of the USD 3.4 billion commitment extends beyond the generators themselves. It includes hardware fabrication, balance-of-plant engineering, and site construction works.

Design contractors are integrating high-efficiency natural gas turbine sets with specialized cooling modules, while construction crews assemble modular power blocks alongside targeted data hall structures to enable rapid deployment.

Why Anthropic Is Skipping the Utility

The choice to build rather than interconnect stems from a bottleneck industry analysts identify as the single largest constraint on modern data center deployment: utility grid interconnection backlogs that can delay projects by several years. Major cloud operators increasingly deploy self-generated natural gas power systems to secure reliable electricity while they wait for high-voltage transmission upgrades.

For Anthropic specifically, securing independent energy assets guarantees the company maintains execution velocity across its multi-hundred-billion-dollar compute pipeline.

The procurement strategy also aligns with the company's long-term capital trajectory as it prepares for an initial public offering.

How the Buildout Will Roll Out

Deployment is organized into three phases. First, Caterpillar delivers initial heavy-duty natural gas generator sets to designated installation sites. Second, engineering teams carry out what is described as civil integration, connecting fuel supply pipelines, microgrid switchgear, and step-up transformers.

Third, on-site power units begin energizing live server clusters without grid reliance, completing operational commissioning.

The phased hardware deliveries will run through 2027 and 2028, targeting a total continuous capacity of 1.7 gigawatts. Beyond that delivery window, no completion date for the full fleet was provided in the report.

What the Initiative Comprises

The initiative combines high-density AI data center infrastructure with distributed natural gas power plant infrastructure. Anthropic PBC is the developer.

The project is located in the United States, though specific campus site coordinates remain confidential.

Its status is listed as commercial agreement executed and a procurement phase active.

Key infrastructure needs 1.7GW generator fleet, gas pipeline interconnections, step-up substations, on-site fuel storage, and microgrid distribution switchgear.

Technology integration spans modular natural gas generator sets, SCADA microgrid controls, high-efficiency heat exchangers, and direct liquid cooling interconnections.

The raw materials required for the buildout include heavy structural steel, high-pressure natural gas piping, high-grade copper wiring, concrete foundation footings, and specialized acoustic cladding.

Thousands of Construction Jobs, Hundreds Permanent

The multi-billion-dollar program is expected to support thousands of specialized engineering, fabrication, and heavy civil construction jobs.

At peak buildout, construction employment is estimated at more than 3,500 workers spanning civil, mechanical, electrical, and pipeline trades. Once operational, the project is expected to support over 450 direct permanent jobs, including power plant operators, electrical engineers, and data center technicians.

In economic terms, the program is positioned to remove grid bottleneck constraints, accelerate deployment schedules, and drive large-scale equipment manufacturing employment. Dedicated power generation guarantees uninterrupted operational uptime for next-generation foundation models.

AI Firms Take Energy Into Their Own Hands

The deal is part of a broader global competition for high-density computing infrastructure.

It references international efforts such as SK Hyper's previously reported pursuit of USD 350 billion to fund a massive data center buildout. Anthropic's transaction extends these regional digital buildout strategies and reinforces a trend in which AI developers take direct control of their energy supply chains rather than relying solely on public utilities.

That shift, from grid customer to power plant owner, is the strategic through-line of the agreement. For Anthropic, the Caterpillar queue, the OnePWR designs, and the installation logistics acquired in the transaction all serve a single purpose: securing a dedicated electricity supply large enough to keep gigawatt-scale training clusters running without waiting on transmission upgrades that may take years to materialize.
