Wärtsilä will supply engines for a power plant intended to support the growth of large-scale artificial intelligence data centers in the United States. The order, valued at €292 million, was placed by Liberty Energy and will be recorded by Wärtsilä during the third quarter of 2026.
Furthermore, the project aims to address one of the most critical challenges for digital infrastructure developers: securing reliable power before grid limitations delay new computing capacity. In this case, on-site generation will accelerate the commissioning of critical facilities and adjust power capacity as AI workloads increase.
Flexible Power for AI Data Centers
Data centers powered by artificial intelligence require stable, flexible, and continuously available electrical supply. Therefore, Wärtsilä’s solution is designed for high-demand operations, where power availability directly impacts system performance.
Likewise, the Wärtsilä 34SG engines will operate on natural gas and offer high efficiency, operational reliability, and low water consumption. This combination is key for high-performance data centers, especially in areas where grid connection or power availability can become bottlenecks.
Modular Capacity of up to 1 GW
The modular design of the engines will enable phased deployment of the power plant, with scalable blocks of up to 1 GW or more. With this architecture, developers will be able to add electrical capacity as AI-related processing demand grows.
Additionally, modularity reduces execution risks in projects where power supply timing is critical. For Liberty Energy, Wärtsilä’s technology strengthens its integrated power platform and enhances its ability to deliver high-efficiency generation to advanced computing environments.
Deliveries Scheduled Between 2029 and 2030
Equipment delivery to the site is scheduled to begin in 2029 and continue through 2030. The agreement also strengthens Wärtsilä’s position in the U.S. data center market, a sector that demands fast, scalable power generation solutions prepared for critical operations.
Wärtsilä Energy has a track record of 81 GW in power plant capacity and more than 130 energy storage installations across 180 countries. The company also develops engines prepared to operate on sustainable fuels, as part of its strategy toward more flexible, low-carbon energy systems.
