Technology group Wärtsilä has secured an order to supply 24 Wärtsilä 50SG gas engines for a 429 MW power plant in the United States, owned and operated by an investor-owned utility. The facility will provide electricity to support a large data centre development. The order was booked in the first quarter of 2026.

The project reflects the growing pressure on US power infrastructure as data centre expansion accelerates nationwide. Wärtsilä’s engine-based generation technology is designed to provide fast, flexible capacity capable of responding to rapid changes in demand while supporting grid stability.

The Wärtsilä 50SG engine offers high efficiency in a compact design and is suited for both baseload and balancing applications. Its fast-start capability enables rapid response to fluctuating loads associated with data centres, as well as variability from renewable energy sources.

Delivery of the engines will follow an accelerated project schedule, with commercial operations expected to begin in late 2028 and early 2029.
