JENBACH, AUSTRIA & HOUSTON -- INNIO Group announced a major order from VoltaGrid for 1.5 gigawatts (GW), reinforcing the companies’ collaboration in behind‑the‑meter (on-site) power generation for AI and high‑performance computing infrastructure.

Under the agreement, INNIO expects to supply a total of 300 Jenbacher gas engines from its Type J624 and Type J620 series. The J624 series is integrated into VoltaGrid’s proprietary QPac™ platform. The engines are packaged into 25 MW units, enabling rapid, scalable deployment for data center customers across the United States. Delivery is scheduled by 2028.

“This landmark order underscores the strength of INNIO’s technology and our commitment to power the growth of AI,” said Dr. Olaf Berlien, President and CEO of INNIO Group. “We are proud to deepen our collaboration with VoltaGrid as we help shape the evolution of energy infrastructure.”

“This is a major step forward in building the energy backbone for the AI era,” said Nathan Ough, CEO of VoltaGrid. “Together with INNIO, we are delivering a scalable, grid-grade solution that offers fast response and eliminates the need for batteries. Our collaboration provides the speed, reliability, and sustainability required to power next-generation data centers.”

Developed jointly by INNIO and VoltaGrid, the solution is engineered to support data center deployment and Graphics Processing Unit (GPU) utilization for AI-driven workloads. Powered by INNIO’s Jenbacher technology, the integrated platform delivers prime, backup, and peaking power within a single system for operational flexibility. The system maintains full power and efficiency at high ambient temperatures with excellent transient performance capable of managing the highly volatile load fluctuations typical of AI computing environments.

The collaboration enables the integration of VoltaGrid’s power pack units with its large-scale portable data center power systems powered by INNIO technology.
