Technology group Wärtsilä has secured an order to supply a 282 megawatt onsite power solution for a data center project being developed by a major U.S. independent power producer in the United States. The power plant will operate with 15 Wärtsilä 50SG engines.
"The order demonstrates the growing need for fast-deployable onsite power solutions as grid constraints, lengthy connection timelines, and accelerating AI-driven electricity demand create power availability challenges for new data center developments. The order was booked by Wärtsilä in Q3 2026," it said.
The project marks the company's seventh data center-related order in the United States, bringing the total power capacity sold by Wärtsilä for U.S. data center applications to more than 3 GW.
The customer selected Wärtsilä engine-based solution for its ability to provide large-scale power capacity on efficient timelines while enabling phased expansion as computing demand grows, Wärtsilä said.
"The Wärtsilä 50SG engines provide high efficiency in demanding operating conditions, feature a closed-loop cooling system that minimises water consumption compared with conventional thermal power alternatives and offer flexibility to convert the engines to run on future fuels. For data center developers, these features translate into dependable power availability, scalable growth, and greater long-term optionality," it said.
The Wärtsilä equipment is scheduled for delivery in 2028, and the project is expected to become fully operational in 2029.
Wärtsilä did not provide additional details on the name of the company or the location of the data center.
