The relentless expansion of artificial intelligence is creating an unprecedented demand for power, pushing data center development to its limits. While traditionally, new facilities have relied on grid connections or on-site power plants, a critical bottleneck is emerging: securing sufficient energy to fuel the AI revolution. Delays in both grid access and the availability of traditional gas turbines are forcing developers to seek innovative solutions.
At the Data Center World Power show in San Antonio this past October, ProEnergy, a leading natural gas power provider, unveiled a compelling alternative: repurposed aviation engines. According to Landon Tessmer, Vice President of Commercial Operations at ProEnergy, an increasing number of data centers are turning to the company’s PE6000 gas turbines to provide crucial “bridging power” during construction and the initial years of operation. Once grid power becomes available, these turbines can seamlessly transition to a backup role, supplement the grid, or even be sold to local utilities.
“We’ve already sold 21 gas turbines for two data center projects, representing over 1 gigawatt of capacity,” Tessmer stated. “These projects anticipate needing this bridging power for five to seven years – the estimated timeframe for securing permanent grid interconnection.”
Aeroderivative Turbines: A Novel Solution to a Growing Crisis
The practice of converting aircraft engines for stationary power generation isn’t new. For decades, gas turbine original equipment manufacturers (OEMs) like GE Vernova and Siemens Energy have successfully adapted proven aircraft engine designs for use in power plants. These “aeroderivative” gas turbines offer significant advantages over traditional heavy-frame turbines, including a lighter footprint, reduced maintenance requirements, and greater operational flexibility.
“Industrializing an aviation engine for power generation is a complex undertaking,” explains Mark Axford, President of Axford Turbine Consultants, a specialist in gas turbine valuation and consulting. “It requires substantial engineering modifications to adapt a machine designed for thrust into one designed for continuous power output.”
GE Vernova’s LM6000 turbine, for example, is directly derived from the widely-used CF6-80C2 turbofan engine found on numerous commercial aircraft. Introduced in 1985, the CF6-80C2 spawned the LM6000 five years later. The conversion involved expanding the turbine section to maximize shaft power, adding robust mounting structures, and implementing advanced control systems. Crucially, modifications also included developing fuel nozzles compatible with natural gas and optimizing the combustor to minimize nitrogen oxide emissions.
The current supply chain constraints are severe. “There simply aren’t enough gas turbines available to meet demand, and the situation is likely to worsen,” warns Paul Browning, CEO of Generative Power Solutions, a former executive at both GE Power & Water (now GE Vernova) and Mitsubishi Power. He notes that ordering an LM6000 from GE Vernova currently carries a waiting list of three to five years, a similar timeframe applies to Siemens Energy’s SGT-A35 aeroderivative turbine. Some popular models face even longer delays.
In stark contrast, ProEnergy can deliver a PE6000 turbine as early as 2027, offering a significantly faster path to power.
From Sky to Server Farms: The PE6000 Advantage
ProEnergy’s innovative approach centers around acquiring and overhauling used CF6-80C2 engine cores – the central component where combustion takes place. These cores are then paired with newly manufactured aeroderivative parts, produced either by ProEnergy or its partners. The resulting refurbished engines are capable of generating 48 megawatts of power, sufficient to power a small-to-medium-sized data center, or approximately 20,000 to 40,000 homes. With an estimated 1,000 CF6-80C2 engines expected to be retired over the next decade, ProEnergy has secured a reliable supply of core components.
The overhaul process restores each engine and its thousands of components to like-new condition through meticulous disassembly, cleaning, inspection, and repair or replacement. Every part within the PE6000 turbine, beyond the core, is manufactured to ProEnergy’s exacting specifications. “We can overhaul the high-pressure core of any CF6-80C2 and fabricate all the low-pressure components,” Tessmer emphasizes.
ProEnergy offers complete two-turbine blocks, including generators, air cooling systems to enhance performance in hot weather, selective catalytic reduction systems to minimize emissions, and comprehensive electrical systems. The company’s focused approach – specializing solely in the CF6-80C2 engine – streamlines engineering and simplifies maintenance.
Originally designed for utilities needing peak-load capacity, the PE6000 is now finding a new purpose in the data center boom, providing continuous power to entire facilities. These turbines operate on natural gas, can start up and reach full power in as little as five minutes, and offer rapid component swapping within 72 hours for maintenance. Emissions average a remarkably low 2.5 parts per million of nitrogen oxide, well below EPA-regulated levels. Since 2020, ProEnergy has produced 75 PE6000 packages and currently has another 52 in assembly or on order.

The Gridlock Factor: Why Bridging Power is Essential
The growing popularity of aeroderivative turbines is driven by more than just the surge in data center construction. Lengthy delays in expanding transmission infrastructure, coupled with local opposition and complex permitting processes, are creating significant hurdles to grid connection. “Aeroderivative gas turbines are proving to be a vital bridging technology, providing power behind the meter until utilities can deliver grid-supplied electricity,” Tessmer explains.
He cites examples of permitting delays stretching eight to ten years. If grid connection timelines remain protracted, and gas turbine manufacturers fail to significantly increase production, bridging power solutions like the PE6000 could become indispensable for enabling the continued expansion of AI infrastructure. What impact will these delays have on the pace of AI innovation? And how will data center operators balance the need for reliable power with sustainability goals?
Frequently Asked Questions About Bridging Power for Data Centers
What is bridging power and why is it needed for data centers?
Bridging power refers to temporary power solutions, like the ProEnergy PE6000, used to supply electricity to data centers while they await permanent grid connections. It’s needed due to significant delays in grid infrastructure development and long lead times for traditional gas turbine procurement.
How does the ProEnergy PE6000 turbine differ from traditional gas turbines?
The PE6000 is an aeroderivative turbine, meaning it’s repurposed from an aircraft engine. This makes it lighter, faster to deploy, and more readily available than traditional, heavy-frame gas turbines, which often have multi-year waiting lists.
What are the environmental benefits of using repurposed aviation engines for power generation?
The PE6000 turbines boast low nitrogen oxide emissions, averaging 2.5 parts per million, which is well below EPA regulations. Furthermore, repurposing existing engines reduces the demand for new manufacturing, contributing to a more circular economy.
How long does it typically take to get a PE6000 turbine operational?
ProEnergy states that a PE6000 turbine can be delivered as early as 2027, a significantly shorter timeframe compared to the three-to-five-year wait times associated with ordering new turbines from major manufacturers.
What is the typical power output of a ProEnergy PE6000 turbine?
Each PE6000 turbine can generate 48 megawatts of power, enough to power a small-to-medium-sized data center or approximately 20,000 to 40,000 homes.
Are there any concerns about the long-term availability of CF6-80C2 engine cores?
ProEnergy anticipates approximately 1,000 CF6-80C2 engines will be retired over the next decade, ensuring a sufficient supply of cores for the foreseeable future.
