Bergen Engines to power US AI Data Center

Bergen has once again struck gold with the US AI industry. OEM Bergen Engines has secured a contract to supply a 400MW power plant for a new AI data center on the US East Coast. Operating fully off grid in true islanded mode, it will be the first medium-speed reciprocating engine power plant in North America designed for AI-driven workloads.

To safeguard the plant against extreme and continuous AI load fluctuations, the project will deploy Piller’s SHIELDX™ Dynamic Power Stabilization units. Using a combination of mechanical inertia and bi-directional active power modules, SHIELDX™ will manage both large sudden load steps and the rapid, frequent transients characteristic of AI workloads. By absorbing these fluctuations, SHIELDX™ reduces the ramp-rate demand placed on the engines, improves fuel efficiency, lowers operational stress, and optimizes maintenance cycles.

The installation will utilize 36 × 11.2MW Bergen medium-speed, lean-burn gas engines, each paired with Marelli high-efficiency alternators. The first batch is scheduled to ship in December 2025.

The project will be delivered by E-Finity Distributed Generation as EPC and long term O&M provider, with Bergen offering post-commissioning support for major service intervals and spare parts provision.

Originally conceived as a 100MW facility, the project has since grown fourfold, reflecting the explosive growth of the AI sector and the mounting pressure on available power infrastructure.

“This contract marks an exciting milestone for Bergen Engines and our partners at E-Finity. Together, we are setting a new benchmark for independent power at AI scale,” said Theo Lorentzos, VP Sales Americas, Bergen Engines. “By combining Bergen’s engines with Piller SHIELDX™, this project delivers the power and stability that modern AI workloads demand.”
