A crippling bottleneck in electrical grid connections and new utility turbine deliveries is driving artificial intelligence infrastructure builders toward radical off-grid solutions. Rather than waiting through multi-year queues to secure conventional power, several data center operators are now generating their own electricity using rebuilt aircraft engines salvage-sourced from retired fleets.
Refurbishing Aviation Turbines to Burn Gas
Technicians pull these powerplants from decommissioned airframes and re-engineer them to run on natural gas. While retrofitted flight equipment does not represent anyone's vision of an ideal permanent generating station, its emergence highlights how severely traditional utility infrastructure has lagged behind the breakneck expansion of AI compute clusters.
For technology operators stranded in connection backlogs, speed of deployment is the primary incentive. Energy analyst Audun Martinsen noted that the priority is getting electricity online as rapidly as possible, explaining that jet-powered generators allow operators to bring an entire data center into service in roughly 24 months.
Years-Long Queues for Grid Infrastructure
By comparison, linking up to traditional regional utilities has become a protracted ordeal. Connecting 100 megawatts of demand to the public grid in Northern Virginia requires an estimated seven years. Compounding the issue, an executive at Mitsubishi Power, a leading manufacturer of generation hardware, indicated that the bulk of forthcoming utility equipment output will not arrive until 2031.
These scheduling gridlocks are already unraveling commercial agreements. Last month, Microsoft abandoned its anchor-tenant commitment at Nscale's facility in Loughton, England, after the local power utility disclosed that it would be unable to provide adequate electricity supply until the early-to-mid 2030s.
Deployment by xAI, OpenAI and Crusoe
Elon Musk's venture xAI ranks among the high-profile operations actively leaning on aviation hardware. To help feed its Colossus 2 computing cluster in Memphis, the firm installed eight retrofitted aero-engine turbines in Mississippi. These units were supplied by ProEnergy, an engineering outfit that overhauls GE powerplants commonly seen on Boeing passenger aircraft.
In 2025, OpenAI took a similar path by incorporating gas-fired turbines at its initial Stargate location in Abilene, Texas. Denver-based developer Crusoe, which is erecting the Abilene campus, placed an order for 13 of ProEnergy's retrofitted units in April.
Crusoe subsequently terminated a $1.25 billion arrangement in September to acquire 29 natural gas turbines from Boom Supersonic, an enterprise designing a supersonic passenger jet that began marketing an industrial turbine variant of its engine to data center developers. A Crusoe representative stated at the time that the company remained committed to using turbines for its projects.
White House Pressure and Emissions Concerns
Policy tailwinds are further pushing the trend, with the Trump administration urging data facility operators to generate electricity on site rather than drawing from regional grids.
Yet relying on repurposed aircraft engines entails significant operational trade-offs. Compared to purpose-built industrial gas plant turbines, aero-derivative conversions burn fuel with lower efficiency, generate higher emissions, and require a greater number of physical units to deliver an equivalent volume of electrical power. Consequently, specialists view modified jet turbines primarily as a makeshift intermediate bridge, warning that fuel economy and environmental footprints will face much sharper scrutiny over the next year or two.
