Data center developers are increasingly turning to discarded jet engines to power their facilities, a less efficient and less environmentally friendly option, because they cannot get timely grid connections or new turbines.
AI infrastructure · Power bottleneck
Data centers turn to retired jet engines for power
Developers facing long grid connection waits and delayed turbine deliveries are adapting discarded aircraft engines to generate electricity. The workaround is less efficient and less environmentally friendly, but it is faster.
How the workaround comes about
Step 1
Grid wait
Years-long wait for access to the electrical grid
→
Step 2
Turbine delays
Newly manufactured turbines are slow to obtain
→
Step 3
Retired jet engines
Aircraft engines adapted to generate electricity
→
Result
Capacity online
Computing capacity comes online sooner
What developers gain
Speed to power when grid access is delayed
A way around the turbine supply backlog
Computing capacity brought online sooner
What the tradeoff costs
Lower efficiency and higher fuel use
Emissions and air-quality considerations
Pressure on sustainability commitments
Uncertain long-term operating costs
Outlook
Power availability, not chips alone, may increasingly decide where and how fast data centers get built.
Whether jet engines remain a niche stopgap or become a wider bridge technology depends on:
Grid upgrades
Turbine manufacturing capacity
Regulatory decisions on emissions and permitting
Scale remains uncertain
There is no comprehensive count of how many facilities use this approach, and its long-term viability is not established.
