Wärtsilä Powers US Data Centers with Natural Gas Engines

Finnish industrial giant Wärtsilä is making a significant push into the U.S. data center market, securing two substantial natural gas engine supply agreements. These deals, one in Ohio and another in Texas, underscore the growing demand for reliable, scalable power solutions to support the relentless expansion of digital infrastructure, particularly driven by artificial intelligence and cloud computing workloads.

The larger of the two agreements involves a 412MW installation for a hyperscale data center project in Ohio. This project will deploy 40 of Wärtsilä's 34SG spark-ignited gas engines. This marks a pivotal entry for the company into the data center sector, leveraging its expertise in modular power generation. The engines are slated for delivery in 2028, with the facility expected to be fully operational by late 2029. Wärtsilä highlights the engines' low water consumption and rapid deployment capabilities as key advantages for data center operators seeking to bypass grid limitations and ensure consistent power availability.

In parallel, Wärtsilä has finalized a 790MW supply contract for a data center facility currently under construction in Texas. This agreement will see 42 of the company's 50SG engines installed. The order was officially recorded by Wärtsilä in the second quarter of 2026. This Texas deal represents Wärtsilä's first foray into the Lone Star State's data center market, adding to its growing footprint in the U.S. The company has now secured over 2.4GW of power capacity for U.S. data centers, demonstrating a strong market reception.

Risto Paldanius, VP of Americas at Wärtsilä Energy, emphasized the critical role of their technology in meeting the accelerating demands of AI and cloud services. He stated, “Operators need energy solutions that are efficient, resilient, and available on their timeline – not the grid’s. Wärtsilä provides that foundation, delivering dependable, high-performance power that scales as quickly as its infrastructure.” The selection of Wärtsilä was attributed to its established reliability, swift deployment, and operational efficiency across varied conditions.

The broader context for these deals is the immense pressure on power grids to keep pace with the energy-intensive nature of modern data centers. The global data center market is projected to grow significantly, with energy consumption being a primary concern. Wärtsilä's natural gas engine solutions offer a compelling alternative to traditional grid reliance, providing primary power that can ramp up quickly and operate independently. This flexibility is crucial for data center developers who require guaranteed uptime and the ability to scale capacity rapidly to meet evolving market needs.

Anders Lindberg, president of Wärtsilä Energy and EVP of Wärtsilä, further elaborated on the benefits, noting that their primary power solutions offer continuous, reliable energy while consuming less water and fuel compared to conventional alternatives. He added, “Our modular engine power plants allow easy capacity scale-ups, making them an ideal choice for the fast-growing data center market.” The company's strategic focus on providing resilient and scalable power infrastructure positions it as a key player in supporting the continued expansion of digital services across North America.
