Cummins Powers Large Scale Data Centers with Natural Gas Generators in West Texas

COLUMBUS, Ind. — Cummins Inc. has announced an agreement with Circe Energy to supply high-powered natural gas generator sets for a scalable, behind-the-meter microgrid serving as the primary power source for high-performance computing data center campuses in Texas.

Deliveries of the HSK78 (C2000N6CD) and QSK60 (C1400N6) generator sets are scheduled from 2026 through 2030. The systems will support Circe’s West Texas campus development and other sites without reliance on the utility grid.

The deal addresses growing power demands from artificial intelligence and other high-density computing applications. Data center developers increasingly are turning to on-site generation to overcome utility interconnection delays and grid constraints while enabling faster deployment and phased growth, as stated by Cummins.

“Data center customers are navigating a new power reality where speed, reliability, and availability are just as critical as capacity—and downtime is not an option,” said Susan Cleaver, executive director of Cummins Global Power Generation business. “Cummins natural gas power solutions help customers meet unprecedented growth in data demand while closing utility power gaps with dependable on-site generation for large, power-intensive facilities.

Cummins will provide the generator sets along with microgrid architecture, integrated controls, and technical validation support. Final system design and implementation remain the responsibility of Circe and its engineer of record. Cummins will also offer operational data sharing, system refinement, and long-term service through its North American network.

Circe’s West Texas campus is designed as a modular platform capable of phased energization beginning in 2027. The facilities are built for high-density AI compute loads and liquid cooling compatibility.

“AI infrastructure depends on both power availability and delivery timing,” said Dagan Baroco, chief commercial officer of Circe Energy. “Securing prime power natural gas generation solutions from Cummins, combined with our microgrid architecture and powered shell design, enables Circe to deliver scalable AI campus infrastructure on a predictable timeline while providing customers with a reliable and cost-competitive alternative to traditional grid-dependent development.”

Zach Gillen, vice president of distribution business sales and service for North America at Cummins, said the company’s experience positions it to support the data center industry’s need for reliable and adaptable energy strategies amid rising AI-driven demand.
