US Data Centers Use Old Jet Engines Amid Power Grid Connection Delays

Several American data centers dedicated to artificial intelligence tasks are generating their own electricity using converted aircraft engines, according to reports. This trend highlights how severely power infrastructure is lagging behind the rapid development of the artificial intelligence sector.

• The primary advantage of converted jet engines is the speed of deployment, allowing data centers to launch within 24 months.
• Connecting 100 MW to the grid in Northern Virginia takes approximately seven years.
• Major tech players like Elon Musk's companies and OpenAI are already implementing alternative turbine generators.

Power Supply Shortages and Project Delays

While the AI industry experiences unprecedented growth, traditional energy grids are struggling to keep up. According to the International Energy Agency, connecting 100 megawatts of power to the grid in Northern Virginia takes about seven years, with major resources expected to come online only by 2031.

Such delays are already resulting in lost business for operators. For instance, Microsoft withdrew as a primary client from Nscale's data center in Loughton, England, after local energy providers stated they could not guarantee sufficient electricity supply until the early-to-mid 2030s.

Industry Adoption of Converted Jet Engines

Faced with grid bottlenecks, companies are turning to independent generation. Elon Musk's SpaceX utilizes eight converted jet engine turbines in Mississippi to power the Colossus 2 data center in Memphis. These units are supplied by ProEnergy, which refurbishes General Electric engines typically used on Boeing aircraft.

Additionally, OpenAI installed gas turbines at its initial Stargate facility in Abilene, Texas, last year. AI infrastructure startup Crusoe is also building a campus in Abilene utilizing 13 retrofitted ProEnergy aircraft engines for power.

Government Policy and Environmental Concerns

The administration is actively encouraging data center operators to produce their own electricity. In February, the US Energy Information Administration suggested utilizing decommissioned military jet engines for power generation, noting that about 4,000 stored aircraft at Davis-Monthan Air Force Base in Arizona could provide up to 40 GW of capacity.

However, converted aircraft engines come with significant drawbacks. They are less efficient and produce higher environmental emissions compared to standard turbines specifically designed for conventional gas-fired power plants.
