Information middle builders are working right into a extreme energy bottleneck as they rush to construct larger amenities to capitalize on generative AI’s potential. Usually, they might energy these facilities by connecting to the grid or constructing a power plant onsite. Nevertheless, they face main delays in both securing gas turbines or in acquiring power from the grid.
On the Information Middle World Energy present in San Antonio in October, natural-gas energy supplier ProEnergy revealed another – repurposed aviation engines. In line with Landon Tessmer, Vice President of Industrial Operations at ProEnergy, some data centers are utilizing his firm’s PE6000 gasoline generators to supply the facility wanted in the course of the knowledge middle’s building and through its first few years of operation. When grid energy is out there, these machines both revert to a backup function, complement the grid, or are offered to the native utility.
“We have now offered 21 gasoline generators for 2 data-center tasks amounting to greater than 1 gigawatt (GW),” says Tessmer. “Each tasks are anticipated to supply bridging energy for 5 to seven years, which is after they anticipate to have grid interconnection and now not want everlasting behind-the-meter technology.”
Bridging Energy Gaps With a New Type of Aeroderivative Turbine
It’s a frequent and long-established apply for gas-turbine unique gear producers (OEMs) like GE Vernova and Siemens Energy to transform a profitable plane engine for stationary electric-power technology purposes. Referred to as aeroderivative gasoline generators, these machines have carved out a distinct segment for themselves as a consequence of being lighter, smaller, and extra simply maintained than conventional heavy-frame gasoline generators.
“It takes loads to industrialize an aviation engine and make it generate energy,” says Mark Axford, President of Axford Turbine Consultants, a gas-turbine marketing consultant and a valuation knowledgeable for used generators.
For instance, GE Vernova’s LM6000 gas turbine was derived from GE’s profitable CF6-80C2 turbofan engine which was broadly used on business jets. The CF6-80C2 was first launched in 1985, and the LM6000 appeared in the marketplace 5 years later. To make it appropriate for power generation, it wanted an expanded turbine part to transform engine thrust into shaft energy, a sequence of struts and helps to mount it on a concrete deck or metal body, and new controls. Additional modifications sometimes embrace the event of gasoline nozzles that permit the machine run on natural gas reasonably than aviation fuel, and a combustor that minimizes the emission of nitrogen oxides, a significant pollutant.
“There simply aren’t sufficient gasoline generators to go round and the issue might be going to worsen,” says Paul Browning, CEO of Generative Power Solutions, previously the top of GE Energy & Water (now GE Vernova) and Mitsubishi Power. Contact GE Vernova to order an LM6000 at the moment (or a Siemens Energy SGT-A35 aeroderivative gas turbine) and also you is perhaps instructed the ready listing is anyplace from three to 5 years. Some massive, fashionable, fashions have even longer ready lists.
For distinction, “a PE6000 from ProEnergy could be delivered in 2027,” Tessmer says.

Transformed Turbofan Plane Engine Can Present 48 Megawatts
ProEnergy buys and overhauls used CF6-80C2 engine cores – the central a part of the engine the place combustion happens – and matches them with newly manufactured aero-derivative components made both by ProEnergy or its companions. After meeting and testing, these refurbished engines are prepared for a second life in electric-power technology, the place they supply 48 megawatts (MW), sufficient to energy a small-to-medium knowledge middle (or a city of maybe 20,000 to 40,000 households). In line with Tessmer, roughly 1,000 of those plane engines are anticipated to be retired over the subsequent decade, so there’s no scarcity of them. A big knowledge middle could have demand that exceeds 100 MW, and among the newest knowledge facilities being designed for AI are greater than 1 GW.
An overhaul returns an engine and its elements to as-new situation. Every of its 1000’s of components are disassembled, cleaned, inspected, after which repaired or changed as wanted. On this means, the engine is renewed for one more lengthy cycle of runtime. Other than the engine core, each half contained in the PE6000 turbine is manufactured to ProEnergy’s specs. “We will overhaul the high-pressure core of any CF6-80C2 and fabricate all of the low-pressure elements,” Tessmer provides.
ProEnergy sells two-turbine blocks with the usual configuration. It consists of gasoline generators, turbines, and a number of different gear, resembling methods to chill the air coming into the turbine throughout scorching days as a strategy to increase efficiency, selective catalytic discount methods to cut back emissions, and varied electrical methods. The corporate focuses solely on one engine, the CF6-80C2, to streamline and simplify engineering and upkeep.
The PE6000 was initially meant to be used by utilities that wanted extra capability throughout peak hours. The data-center boom has turned that expectation on its head—data-center operators need these engines to supply energy to your entire facility. They run on pure gasoline and, when being began, could be up and working in 5 minutes. If one wants upkeep, it may be swapped out with a spare inside 72 hours. Emissions ranges common 2.5 components per million for nitrogen oxide, which is effectively under EPA-regulated levels (usually under 10 to under 25 components per million, relying on the use case). Since 2020, ProEnergy has fabricated 75 PE6000 packages and now has one other 52 being assembled or on order.
Prolonged Grid-Connection Delays Imply Extra Enterprise
A number of components contribute to this recognition. In addition to the surge in knowledge facilities, there’s usually a lengthy wait for transmission lines, which can face native opposition and require permits from a number of municipalities or states. “Aeroderivative gasoline generators are gaining floor as a bridging expertise that runs behind the meter till the utility is ready to provide grid energy,” says Tessmer.
Tessmer has seen examples of eight-to-ten-year delays on allowing alone. If connecting to the grid continues to take years, no less than in some areas, and if gasoline turbine producers don’t dramatically increase output, bridging energy might turn out to be an indispensable enabler of the buildout of AI infrastructure.
