Wärtsilä to Supply 412 MW of Gas-Fired Power for U.S. Data Center

Wärtsilä will supply 412 MW of gas-fired power for a U.S. data center project, enabling off-grid operations. The move highlights rising demand for natural gas to support energy-intensive AI infrastructure.

(P&GJ) — Wärtsilä will supply 412 MW of gas-fired engine power for a new data center project in Ohio, underscoring growing reliance on natural gas to meet rising energy demand from large-scale computing facilities.

The project includes 40 gas-fired engines and will provide primary power for the site, allowing it to operate independently of the grid. The approach reflects increasing challenges around grid interconnection timelines in the U.S., particularly for energy-intensive data center developments.

Gas-fired, modular engine systems are being deployed as a flexible solution to deliver reliable power while avoiding delays tied to transmission constraints. The Ohio project marks the first use of Wärtsilä’s 34SG engine in a data center application.

The order adds to a growing pipeline of U.S. data center projects utilizing gas-based generation, highlighting the role of natural gas in supporting expanding AI and cloud infrastructure.

Equipment deliveries are expected to support a planned startup in early 2028.
