Everllence to Supply 480MW of Gas Engines to US Data Center Developer

German engine manufacturer Everllence has signed a supply agreement with an unnamed US data center developer to deliver 480MW of gas engine capacity, marking one of the company's largest behind-the-meter power projects to date. The deal underscores the growing role of on-site generation in addressing grid constraints for data center operators across North America.

Under the agreement, Everllence will provide 24 of its 18V51/60G gas engines, which are designed to power the data center behind the meter, bypassing direct grid connection. Deliveries are scheduled in two phases, with deployment beginning in mid-2026 to align with the data center's commissioning timeline.

“This contract is one of our most important off-grid data center projects in the United States and strengthens our position in a rapidly evolving digital infrastructure sector. In a market traditionally dominated by gas turbines, our medium-speed engines offer a valuable alternative that is ideal for data centers without direct grid access. They deliver stable power quality, ensure maximum reliability, and can respond quickly to load changes,” said Johann Stocks, head of Power, Americas at Everllence.

The 18V51/60G is an 18-cylinder, four-stroke gas engine with a capacity of 24MW per unit. Everllence claims the engine can operate on natural gas, hydrogen, and biofuels, offering flexibility as the industry transitions toward lower-carbon energy sources. The company has already deployed 124MW of the same engine model across six units in partnership with Kerrville Public Utility Board to help stabilize local power supplies.

Everllence, headquartered in Augsburg, Germany, has traditionally served the maritime sector but is now pivoting toward digital infrastructure as a key growth area. The company specializes in propulsion, power generation, and low-carbon technologies such as heat pumps and carbon capture. In 2026, Bain Capital acquired a majority stake in the company from the Volkswagen Group, which retained a minority position.

The deal reflects a broader industry trend in which data center developers are increasingly securing dedicated, on-site power generation to overcome grid interconnection delays and capacity shortages. With hyperscale and enterprise data center demand continuing to surge, particularly in regions with constrained grids, medium-speed gas engines are emerging as a viable alternative to gas turbines for behind-the-meter applications.

Everllence has been actively expanding its data center-focused product line. Last month, the company launched a new backup generator set tailored for the data center market. The 175D high-speed engine supplies 2.4MWe of standby power and is expressly designed with the data center in mind, according to the company.
