Grid-Free Power | Bergen Engines

Grid-Free Power.

Always On.

Langley Holdings’ Power Solutions Division unites three world-class engineering names – BERGEN Engines of Norway (formerly Rolls-Royce Bergen Engines), Marelli Motori of Italy, and Piller Power Systems of Germany – to deliver modular, utility-grade power anywhere the grid can’t reach or keep up.

Modular Power for the World’s Most Demanding Applications

When the grid can’t reach or is restricted, our integrated behind-the-meter power platform delivers continuous, utility-grade electricity to almost anywhere on earth. At its heart are Bergen Engines of Norway and Marelli Motori of Italy – two world-class names in continuous-duty generation. Bergen Engines, formerly part of Rolls-Royce, bring over 75 years of medium-speed engine expertise, powering some of the most demanding installations worldwide. Marelli’s alternators – trusted as one of the largest OEM suppliers to Caterpillar – convert that power with uncompromising quality. This modular platform scales in 12 MW increments, from 12 MW to 500 MW+, with fuel flexibility that includes natural gas, LNG, liquid fuels, and up to 25% hydrogen blend without modification – and ready for tomorrow’s zero-carbon fuels.

Proven in the Harshest Conditions

The 170 MW Iron Bridge power plant in Western Australia is a showcase of what our platform can achieve. Combining Bergen/Marelli base-load generation with 150 MW of solar, it powers a remote mine and township located more than 100 km from the nearest grid connection – delivering stable, continuous electricity in one of the most challenging operating environments on the planet.

That same proven technology now powers the next generation of mission-critical AI data centres, hybrid renewable installations, and large-scale industrial facilities.

SHIELDX™ – Power conditioning for AI computing environments

For hyperscale and AI-intensive data centres, base-load generation alone isn’t enough – the power must be perfect.

That’s where Piller’s SHIELDX™ Dynamic Power Conditioning & Stabilisation (DPCS) comes in. Built to handle full-scale AI transient load steps in real time, SHIELDX™ provides:

Tier IV fault tolerance and up to 99.999% uptime
True short-circuit contribution and high fault-clearing capability
Zero energy storage degradation over its lifecycle
Precise voltage and frequency stability under any load profile

Piller technology is already trusted to protect some of the worlds most critical infrastructure – including the Bank of England, New York Stock Exchange, London Stock Exchange, the Federal Reserve and the CIA. With SHIELDX™, data centres gain that same uncompromising level of conditioning, resilience and security – whether paired with on-site generation, hybrid renewables, or the utility grid.

Nothing protects quite like Piller.

Rapid Deployment, Infinite Flexibility

While new grid connections can take up to a decade, our modular approach means your power is online in months, not years – faster than any other high capacity solution. Start with the capacity you need today, then scale in 12 MW steps as demand grows – up to 500 MW+.

Still want backup standby operations? Our platform can be configured to deliver rapid-start capability, bringing full load generation online in minutes when you need it most.
