Data Centers Turn to Repurposed Jet Engines for Temporary Power During Grid Delays

Multi-year interconnection waits plus turbine backlogs are fueling a gigawatt-scale market for trailerized aeroderivative units.

Overview

  • ProEnergy says it has sold 21 gas-turbine units for two data-center projects exceeding 1 gigawatt, intended to provide five to seven years of bridging power until grid connections are in place.
  • Since 2020, the company has fabricated 75 PE6000 packages with another 52 in assembly or on order, each delivering about 48 megawatts with five-minute starts, 72-hour swap-outs, and roughly 2.5 ppm NOx.
  • Original equipment manufacturers face multi-year backlogs, with typical delivery times of three to five years and some forecasts extending past 2029, according to industry reports.
  • Trade press reports that nearly 30 LM2500XPRESS units are being deployed near Abilene, Texas, highlighting visible hyperscaler use of ex-airliner-derived turbines for on-site generation.
  • Developers cite permitting and interconnection timelines reaching eight to ten years in some cases, driving behind-the-meter generation as a stopgap while utility infrastructure catches up.
