Everllence to supply 480 MW to US off- grid datacentre
Everllence has signed an agreement with a US datacentre to deliver 24 × 18V51/60G gas fuelled piston engines – total output 480 MW – to a hyperscale datacentre operating completely off- grid. The engines will run on natural gas and meet required, strict emission standards thanks to SCR and oxidation catalysts. The modular setup, with 24 individual units, will ensure flexibility and allow rapid capacity expansion as the project’s energy demand grows, says Everllence. Johann Stocks, Head of Power, Americas at Everllence, said: “In a market traditionally dominated by gas turbines, our medium speed engines offer a valuable alternative that is ideal for datacentres without direct grid access. They deliver stable power quality, ensure maximum reliability, and can respond quickly to load changes.”
In the USA, datacentre operators typically wait several years for a grid connection, Everllence notes, whereas its engines enable operators to immediately establish a power system for the project site that is separate from the grid.
Large medium speed gas engines offer a range of benefits, suggests Everllence, not least flexibility and the ability to be ramped up or shut down within minutes to maximise efficiency and lower emissions. Start-up time is less than five minutes and simple cycle efficiency is up to 50%. Everllence machines employ digital services such as PrimeServ Assist and CEON TechBot, “leveraging data analytics and AI to improve availability, reduce unplanned downtime, and support informed operational decisions.” The gas version, 51/60G, is hydrogen ready and can operate with up to 25% H2
. 175D genset
A recent addition to the Everllence portfolio of machines targeted at datacentre applications is the 175D genset, introduced recently as an emergency/back-up power supply for datacentres.

accordance with international standard ISO 8528 5. According to Marius Zasche, Global Business Development Highspeed at Everllence, “Everllence is the only supplier that provides datacentre operators with both medium speed engines for primary power supply and high speed units for backup.”
The standardised 50 Hz 175D genset can be flexibly integrated into containerised solutions, says Everllence, and it employs a compact design with high power density.
The 175D genset complies with NOx emission
limits in line with US EPA Tier II and supports alternative fuels, being HVO-capable and methanol- ready. This makes it suitable for operators seeking to eventually decarbonise their power supply, notes Everllence. A single-stage, high performance turbocharging system ensures fast response and stable power output.
B&W signs up for Siemens Energy steam turbine gensets
Babcock & Wilcox has signed an agreement with Siemens Energy to start work on 20 steam turbine gensets totalling 1 GW for use in its FastPower programme for datacentre projects.
This agreement is in addition to a previous 1 GW B&W order placed with Siemens Energy for steam turbine gensets to be deployed at an Applied Digital AI factory.
“B&W is focused on helping customers meet one of today’s most critical challenges: bringing reliable power online as quickly as possible,” said Brandy Johnson, CTO of B&W.
AVK launches AVK Capital to fund, own and operate on-site power
AVK has launched AVK Capital, a dedicated funding entity that will finance and own on-site power infrastructure and deliver it to customers as a service, giving datacentre developers a route to a powered site without carrying the capital cost of the power infrastructure on their own balance sheet. Grid connection queues, constrained capacity and the long timescales attached to transmission upgrades hold projects back, and the upfront cost of building on- site generation is a second barrier that sits behind the first, says AVK. Under the old
model, developers have carried the full cost of standby and generation infrastructure on their own balance sheet, and tenants have grown reluctant to commit without confirmed power, a combination that has stalled projects across the market.
Under the new model, AVK selects and engineers the right power solution for the site, drawing on microgrids, AVK PowerPods, fuel cells, renewables integration and standby systems. AVK Capital funds and owns the resulting infrastructure, and the customer secures power through a long-term power

purchase agreement, treating energy as an operating cost rather than a capital investment. “This is an addition to what AVK does rather than a change of direction,” said Ben Pritchard, Chief Executive Officer, AVK. “Core AVK carries on delivering the standby, prime and modular power our customers rely on, exactly as it always has. AVK Capital sits alongside that business and gives customers a clear choice. If they want to fund a project themselves, we will build it. If they would rather we funded, owned and operated it, we can now do that too.”
