Anthropic secures $3.4B deal for 1.7GW gas-powered AI data center

Bypassing the grid bottleneck

Anthropic has finalized a massive $3.4 billion agreement to secure 1.7 gigawatts of heavy-duty, gas-fired generation equipment. This deal stands as the biggest single procurement of power-making machinery ever completed by an artificial intelligence company. The move is designed to provide continuous, utility-scale electricity directly to off-grid campus locations.

The primary driver for this strategy is the significant bottleneck created by traditional electric utility interconnections. Many data center projects face delays of several years while waiting for high-voltage transmission upgrades from public providers. By creating its own power source, Anthropic can maintain execution velocity across its multi-hundred-billion-dollar compute pipeline.

The deal was finalized in late September with OnePWR Solutions, a San Antonio-based energy infrastructure provider. Rather than buying the company itself, Anthropic took over the specific production slots, technical blueprints, and setup procedures needed for the hardware. This allows the firm to jump to the front of the line for essential heavy machinery.

Securing the supply chain

A key component of this deal involves a strategic takeover of manufacturing slots with Caterpillar Inc. OnePWR Solutions had placed a massive equipment order with Caterpillar two years ago, and Anthropic has now assumed those rights. This ensures that the company has a guaranteed path to obtaining the hardware needed for its 1.7-gigawatt capacity.

The equipment package utilizes advanced natural gas generators designed for both base-load and peak-shaving operations. Base-load refers to the minimum amount of power needed to run a facility constantly, while peak-shaving helps manage spikes in demand. These generators will supply high-density server racks that require immense amounts of electricity to function.

The total $3.4 billion commitment is comprehensive, covering the production of hardware, the necessary supporting systems, and the overall building of the site. Design contractors are currently integrating high-efficiency natural gas turbine sets with specialized cooling modules. This turnkey approach ensures that the power generation and the data hall structures are built in tandem.

Engineering and construction

The project involves a complex three-phase deployment plan to get the facility operational. Phase one focuses on Caterpillar delivering the initial heavy-duty natural gas generator sets to the designated installation sites. Phase two involves civil integration, where engineering teams link the fuel delivery systems, the microgrid control switches, and the voltage-increasing transformers.

The final phase is operational commissioning, where the on-site power units begin powering live server clusters without any reliance on the public grid. To achieve this, construction crews will assemble modular power blocks alongside the data hall structures. This modularity is intended to ensure rapid deployment of the necessary infrastructure.

The project requires a wide array of raw materials, including heavy structural steel, high-pressure natural gas piping, and high-grade copper wiring. It also necessitates concrete foundation footings and specialized acoustic cladding. These components are essential for building a facility that can handle the physical demands of high-density computing.

Economic and industrial impact

This infrastructure program is expected to have a significant impact on the labor market. During the peak buildout, the project is estimated to support more than 3,500 specialized jobs in civil, mechanical, electrical, and pipeline construction. Once completed, the facility will support over 450 permanent roles for power plant operators, electrical engineers, and data center technicians.

Industry analysts note that major cloud operators are increasingly turning to self-generated natural gas systems to secure reliable electricity. This trend is becoming a standard strategy for securing the power needed for next-generation foundation models. By securing independent energy assets, Anthropic aims to protect its long-term capital trajectory as it prepares for an initial public offering.

The project faces several delivery risks, including complex natural gas fuel delivery logistics and environmental permitting compliance. There are also potential delays in procuring long-lead transformers. However, by removing the grid bottleneck, Anthropic intends to accelerate its deployment schedules and drive large-scale equipment manufacturing jobs across the country.
