Wartsila Continues Expand Tender

Technology group Wartsila will supply an off-grid energy power solution for a new data center facility under construction in Texas USA. The 790 MW power plant will operate with 42 Wartsila 50SG engines running on natural gas. By opting for a primary power source using Wartsila engines the facility can ensure fast access to reliable power. The order was booked as intake by Wartsila in Q2 2026.
Texas is a key region for artificial intelligence model training and large-scale infrastructure buildout with an urgent need for power that the grid cannot currently adequately provide. Wartsilas engines represent a proven efficient and reliable solution for the quickly evolving requirements of large-scale data center developments.
Wartsilas engines were chosen ahead of other competing technologies for a variety of reasons including their ability to operate at full capacity even in temperatures exceeding 100 degrees Fahrenheit (approximately 38 degrees Celsius) a critical feature for optimized performance in Texas. Furthermore with a heat rate of approximately 6800 Btu/kWh (approx. 50% efficiency) Wartsilas high-efficiency engines dramatically lower fuel costs and guarantee low plant emissions which helps data center developers meet emissions requirements. This in turn allows for faster permitting within environmental and regulatory approvals.
Wartsilas primary power solutions offer significant benefits to data center developers by providing continuous reliable primary power while using significantly less water and fuel than traditional alternatives. Also our power solutions ramp up quickly and offer a dependable and sustainable foundation for delivering power availability which is vital for AI and cloud operators. Our modular engine power plants allow easy capacity scale-ups making them an ideal choice for the fast-growing data center market says Anders Lindberg President of Wartsila Energy and Executive Vice President of Wartsila.
Texas offers a rare combination of deep natural gas supply extensive energy infrastructure and rapidly expanding renewable capacity - an ideal foundation for large-scale data center development. Wartsilas flexible engine technology is ideally suited to this landscape delivering reliable dispatchable power while integrating seamlessly with renewable energy power sources. Together Texas energy advantages and Wartsilas proven engine platform enable data center developers to scale with confidence. And once a data center gets connected to the grid it can be used to balance the renewables in the grid.
The Wartsila equipment is scheduled for delivery in 2028 and the plant is expected to become fully operational in late 2029. This is Wartsilas fifth data center related order in the USA and its first in Texas. Altogether Wartsila has thus far sold over 24 GW of power capacity for US data centers.
