Technology group Wärtsilä will supply engines for a power plant to ensure reliable supply of energy for large-scale data center development in the U.S. The €292 million order, expected to be booked by Wärtsilä in Q3 2026, was placed by Denver-based Liberty Energy, a leading U.S. energy services company. For developers, this means faster time to power, reduced exposure to grid delays, and the ability to scale capacity in line with rapidly evolving AI workloads. The selection of Wärtsilä highlights the company’s strength in supplying power solutions for the fast-growing U.S. data center sector.
AI-driven data center projects require reliable, flexible on-site power capacity that can be rapidly deployed to offer predictable performance and availability. This capability helps mitigate risks related to grid connection delays or constrained power availability.
“AI data center growth is accelerating demand for critical next-generation on-site power infrastructure,” says Ron Gusek, Chief Executive Officer at Liberty Energy. “Wärtsilä’s proven engine technology strengthens our integrated power platform, enhancing our ability to deliver reliable, high-efficiency power generation to meet the demanding requirements of advanced computing environments.”
Designed for high-performance, AI-driven data centers, Wärtsilä engines deliver the efficiency, reliability, and low water consumption needed for critical operations. Wärtsilä 34SG engines run on natural gas, a platform proven to perform in demanding, high-temperature environments. Their modular design enables phased deployment in scalable blocks of up to 1 GW and beyond, allowing developers to bring capacity online faster while keeping pace with rapidly growing AI-driven demand.
“This valuable order reflects Wärtsilä’s continued momentum in the data-center sector and highlights our role in supplying large-scale engine-based power solutions for mission-critical applications,” comments Risto Paldanius, Vice President, Americas at Wärtsilä Energy. “Wärtsilä’s competitive edge is typically based on modularity, speed of deployment, reliability, and strong operational performance. Engine-based solutions can also offer delivery and execution advantages in fast-moving projects where time to power is critical.”
The equipment delivery to site is scheduled to begin in 2029 and continue through 2030.
