Bergen Engines Secures 500MW+ of Orders from Liberty Energy to Advance Power Services for AI Data Centers.

Next-generation AI infrastructure powered by Bergen Engines and Piller SHIELDX™ Technology for Liberty Energy data center deployments

Bergen, Norway / Denver, USA - Bergen Engines today announced an award from Liberty Energy for more than 500 megawatts ("MW") of on-site power generation capacity for large-scale AI data center developments in the United States.

The projects may operate fully off-grid, in true island mode, or grid parallel, providing a comprehensive power solution designed to meet the demands of high-density AI computing environments.

The developments form part of Liberty Energy's strategy to deploy scalable, on-site power infrastructure tailored to the unique requirements of AI data centers, combining rapid deployment capability with long-term operational resilience. By partnering with Bergen Engines (formally Rolls-Royce Bergen Engines), Liberty is leveraging proven medium-speed generation technology to deliver reliable, high-capacity power systems independent of grid constraints.

The projects are being developed by Liberty Energy through its Liberty Power Innovations (LPI) division, a purpose-built platform focused on deploying distributed power infrastructure to support the growing demands of AI-era data centers.

As AI infrastructure continues to scale, data center developers are turning to uniquely engineered solutions to overcome grid limitations and accelerate deployment timelines. These AI facilities introduce highly dynamic and unpredictable load profiles, placing new demands on both power generation systems and the stability of sensitive IT infrastructure.

Under the agreement, Bergen Engines will supply 45 × B36:45V20 AG1 gas generator sets, each rated at 11.2Mwe, delivering a total installed capacity of over 500MW. The medium-speed reciprocating engines can operate in true island mode, forming the backbone of a fully independent power system.

The solution integrates Bergen Engines' gensets with Piller Power Systems' SHIELDX™ Dynamic Power Stabilization technology, both part of Langley Holdings' Power Solutions Division. This flywheel-based architecture continuously absorbs and manages sub-second AI load step variations of up to 30%, protecting the generation assets while delivering stable, conditioned power across a 20+ year operating lifecycle.

This integrated architecture enables the system to manage extreme load transients without requiring oversized generation capacity, improving efficiency while reducing fuel consumption, emissions, and overall system footprint.

"AI data centers are fundamentally changing how power infrastructure can be designed and deployed, and this initial order with Bergen Engines reflects a shared commitment to providing reliable, high-efficiency power solutions to support critical data center infrastructure growth," said Ron Gusek, CEO of Liberty Energy. "Collaborating with Bergen Engines strengthens our power platform, serving as an important component of our broader integrated solution that includes LPI's Forte modular power generation architecture and Tempo power quality system. Together, we will be able to deliver essential power generation infrastructure to support the demanding requirements of next-generation computing."

"These environments require robust baseload generation and the ability to respond to rapid and significant load fluctuations," said Theo Lorentzos, Vice President Sales Americas at Bergen Engines. "By working in partnership with Liberty and integrating SHIELDX™, we are delivering a solution that combines proven generation performance with the flexibility required for AI-driven demand profiles."

"SHIELDX™ protects the generation assets from highly dynamic, sub-second load behavior, enabling stable plant operation under extreme load fluctuations," said Dean Richards, CEO of Piller Power Systems. "This ensures optimal engine performance while delivering consistent, high-quality power to the data center."

Deliveries are scheduled to commence in the second half of 2027.

The agreement reflects a broader shift in the U.S. energy and technology sectors, as the expansion of AI drives investment in dedicated, on-site power infrastructure. As grid capacity struggles to keep pace with demand, integrated solutions such as this are enabling a new generation of resilient, scalable data center deployments.

ABOUT BERGEN ENGINES
Bergen Engines produces medium-speed engines and generator sets to a broad range of land-based, commercial marine, and naval applications. The Bergen name is a watchword for quality and reliability in its field. The tradition of engineering in Bergen, Norway, dates to 1855 when the original company Bergen Mekaniske Verksted (BMV) was founded. In 1946, the company built its first diesel engine and has since commissioned over 7,500 of its iconic liquid and gas fueled engines. Around half of them are still in operation today. Formerly Rolls-Royce Bergen Engines, on 31st December 2021, the company became part of the privately owned British engineering group, Langley Holdings plc.

ABOUT PILLER POWER SYSTEMS
Piller technology is the Gold Standard premium power technology. For many of the world's best known central banks, stock exchanges, financial institutions and governmental agencies; data center operators, telecoms networks and airports, hospitals, semiconductor and pharmaceutical manufacturers, Piller is the go-to technology for mission-critical power reliability. And now, as AI data center operators increasingly go to behind-the-meter (BTM) power, Piller technology is finding a whole new purpose managing AI transients and BTM load steps with ease. In 2016 Piller acquired the Austin TX kinetic energy storage producer, Active Power Inc. Piller Group GmbH is a wholly owned subsidiary of the UK engineering and industrial group, Langley Holdings plc and is part of the Power Solutions Division.
