Wartsila Books 1,202 MW of US Data Center Engine Orders

Wartsila booked 1,202 MW of US data center engine orders, including a 790 MW deal in Texas and a 412 MW project in Ohio, pushing its total US data center capacity sold past 2.4 GW.

What Was Announced

The Texas order, booked in Q2 2026, involves 42 Wartsila 50SG engines running on natural gas for an undisclosed data center operator. Equipment delivery is slated for 2028, with the plant expected to be operational by late 2029. This marks Wartsila’s fifth US data center order and its first in Texas, according to a GlobeNewswire announcement on April 23, 2026.

Separately, a 412 MW order in Ohio will deploy 40 Wartsila 34SG engines, marking the first time this engine model is used in a data center application. These engines will provide primary power for a hyperscale site, enabling independent operation from the grid. Equipment delivery is also scheduled for 2028, with a commercial launch anticipated in early 2028, as reported by GlobeNewswire on April 16, 2026.

Why It Matters

These orders underscore the growing demand for on-site power generation to support the energy-intensive needs of hyperscale data centers, particularly those serving AI workloads. The ability to operate independently of the grid, as stated for the Ohio project, addresses reliability concerns and potential grid constraints in high-demand areas. Wartsila’s total US data center engine capacity now exceeds 2.4 GW, indicating a significant market presence in this sector.

The scale of these projects, particularly the 790 MW Texas deal, positions Wartsila as a key supplier for data center operators seeking to secure substantial power capacity. The actionable takeaway for market observers is the continued trend of data center developers investing heavily in distributed generation to meet escalating power requirements.

Critical Perspective

Given the multi-year timelines for equipment delivery and plant operation, what are the specific contractual provisions and financial assurances in place to mitigate schedule slippage or cost overruns, particularly considering the volatility in commodity prices and supply chain disruptions that could impact a project with a late 2029 operational target?
