When "aircraft engines" become targets for "data center power supply"
```
In the AI computing power arms race, every engine of the economy has been swept into this battle—including jet engines.
As Silicon Valley giants scramble to find stable power sources, an unexpected solution is crossing over from aviation: converting retired Boeing jet engines into ground-based gas turbines to supply direct power to data centers.
With the exponential growth in electricity demand from AI data centers, the lag in traditional grid expansion has become the industry's common enemy. Against this backdrop, companies like FTAI Aviation and ProEnergy are accelerating the "downscaling" of aerospace power assets into the electricity market. This cross-industry experiment not only changes the fate of retired aircraft but is also reshaping the global landscape of distributed energy supply.
The Premium of Speed: Spot Market vs. Long Lead Time
In the power equipment sector, time is money. Currently, the global gas turbine market is dominated by three giants—GE Vernova, Siemens Energy, and Mitsubishi Heavy Industries (MHI)—controlling about 80% of the market share. However, due to surging demand, these giants’ heavy-duty gas turbine orders are backed up for several years.
This supply-demand mismatch has created an opportunity for aviation asset management companies like FTAI Aviation. According to FTAI President David Moreno, it takes only 30 to 45 days to convert an aircraft engine into a power turbine. Although initial design and adaptation take about 18 months, once in the conversion process, their delivery efficiency far surpasses that of traditional energy giants.
This “spot advantage” has sparked intense resonance in the capital markets. Since announcing its entry into the electricity business, FTAI’s stock price has risen about 42%. Jefferies estimates this business could contribute $750 million in EBITDA annually to FTAI, equivalent to 52% of analysts' previous full-year forecasts for the company.
Downscaling: From “High-Stress Takeoff and Landing” to “Stable Power Generation”
Technically, converting aircraft engines for land-based power generation (aeroderivatives, i.e. aviation-modified turbines) is highly feasible.
Aircraft turbine expert Mark Axford points out that the core of the conversion involves two key changes: first, replacing the fuel nozzles so they can burn natural gas instead of jet kerosene; second, swapping the large flight fan at the front for a smaller fan better suited for power generation.
From an asset lifetime perspective, this is more like a precise “residual value recreation.” Narrow-body aircraft engines (like the CFM56 used by the Boeing 737) must endure frequent high-stress takeoffs and landings, but once converted for ground power generation, the wear they experience is greatly reduced. FTAI can extend the service life of aviation components with only a few residual years left for several more years in the power generation field.
Currently, many players are entering this track: ProEnergy is converting Boeing 747 engines; the startup Boom Supersonic also plans to deliver its modified gas turbines to AI data center provider Crusoe in 2027.
Efficiency Battle and Supply Chain Butterfly Effect
In the face of new challengers, traditional giant GE Vernova’s CEO Scott Strazik recently stated on an earnings call that he does not see these smaller units as direct competition. His key argument is “efficiency”: over a 20-year operating cycle, the fuel efficiency advantage of heavy-duty gas turbines remains fundamental to the finances of data center operators.
However, market research firm Thunder Said Energy points out that while heavy-duty turbines are more efficient, they are expensive and have long delivery times. To make up for the efficiency gap, both FTAI and Boom Supersonic claim their products can be configured in “combined cycle” mode, adding a steam turbine to capture waste heat, thus pushing their efficiency closer to that of heavy-duty units.
The deeper impact lies in the scale of potential capacity. Jefferies analyst Sheila Kahyaoglu notes that about 1,600 commercial engines are retired globally each year; if one-third were converted for power use, it would add 13GW of capacity—about a quarter of the world's annual new capacity. The U.S. Energy Information Administration (EIA) even estimates that the potential conversion of retired military engines could reach 40GW.
However, this capacity shift is not without risks. If a large number of aviation components are diverted to the power sector, it could further intensify the already severe shortage in the aircraft maintenance market, creating a chain reaction that increases operating costs for airlines worldwide.
