Cummins will supply natural gas generator sets for Circe Energy’s West Texas AI/HPC data center campus as part of a behind-the-meter, prime power microgrid approach aimed at reducing dependence on utility timelines. Deliveries are scheduled from 2026 through 2030.
The agreement calls for Cummins’ HSK78 (C2000N6CD) and QSK60 (C1400N6) natural gas generator set platforms. Cummins described the deployment as a scalable “prime power microgrid solution,” with the generators used as the primary power source for Circe’s AI/HPC data center campuses, including the West Texas development.
For data center engineers, the practical implication is straightforward: behind-the-meter natural gas generation is being treated less like standby capacity and more like an energization strategy when grid interconnection timing and capacity are uncertain. That shifts the engineering focus toward microgrid controls, phased build-out planning, and how the on-site plant will coordinate with eventual utility interconnection rather than assuming the utility is the primary supply on day one.
Circe said its West Texas campus is designed as a modular deployment platform capable of phased energization beginning in 2027. The campus plan includes “HPC-ready powered shell facilities” intended for high-density AI compute and “liquid cooling compatibility,” with long-term scalability as a design goal.
Cummins said it will support data center and AI campus projects with natural gas power generation systems, microgrid architecture and integrated controls, HPC-focused microgrid design, operational data sharing and refinement, and pre-configuration, validation, and testing through its Power Integration Center (PIC) microgrid laboratory. Cummins also cited long-term service support through its North American service network.
“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 said it is providing the power generation equipment and technical validation support, while Circe and its engineer-of-record retain responsibility for final system design and implementation. “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,” said Dagan Baroco, chief commercial officer of Circe Energy.
