Wartsila secures 282 MW onsite power order for U.S. data center project

The October 5 release specifies 15 engines, delivery scheduled in 2028 and operation expected in 2029. More than 3 GW refers to capacity sold for data centers, not capacity already delivered.

Wartsila announced on October 5, 2026 that it secured an order to supply 282 megawatts of onsite power equipment for a U.S. data center project being developed by a major independent power producer. The plant is planned to use 15 Wartsila 50SG engines.

The company booked the order in the third quarter of 2026. It schedules equipment delivery in 2028 and expects the project to become fully operational in 2029. Those are future milestones, not a report that the plant is operating now.

Wartsila calls this its seventh data-center-related order in the United States. It says total capacity sold for U.S. data center applications now exceeds 3 gigawatts. Sold capacity is not the same as equipment delivered or generation already available on the grid.

The company says the engine-based design supports phased expansion as computing demand grows. It describes closed-loop cooling and possible conversion to future fuels as features. The release does not quantify water savings or establish that the plant will initially run on hydrogen or other low-carbon fuels.

Wartsila attributes demand for onsite generation to grid constraints, long connection timelines and rising electricity demand associated with AI. The announcement does not independently establish a seven-year delay in every named U.S. power market or a specific household bill impact.

The supported milestone is a new equipment order with a 2028 delivery schedule and expected 2029 operation. The release does not identify the project customer or location, and its commercial forecasts should not be read as completed construction.
