US data centres turn to aircraft engines for power amid AI boom

The explosive growth of AI computing has created unprecedented strain on power infrastructure across the United States, with data centre operators struggling to meet electricity demands that far exceed traditional forecasts. Unable to wait for conventional grid upgrades, technology companies managing these facilities have begun repurposing decommissioned aircraft engines as portable generators, a solution that enables rapid deployment of additional power capacity.

Retired jet engines offer several advantages for this purpose. They can be installed and operational significantly faster than building new power plants or upgrading existing grid infrastructure, which typically requires lengthy permitting and construction timelines. The engines, salvaged from commercial aircraft retirement programmes, provide substantial generating capacity and can run on various fuel types, offering operational flexibility to data centre operators.

This trend underscores the severe energy crunch facing the AI sector in the United States. Major technology firms developing large language models and other advanced AI systems have found that existing power supplies cannot support their computational requirements, creating bottlenecks in expansion plans. The shift toward alternative power solutions, including renewable energy partnerships and unconventional generation methods, reflects the industry's determination to maintain growth despite infrastructure constraints.

The reliance on repurposed engines also highlights broader challenges facing energy infrastructure in developed economies. As demand for computing power continues accelerating, policymakers and utility companies face mounting pressure to modernise grid systems and expand generation capacity to support emerging technologies. Industry analysts suggest that sustaining AI sector growth may require fundamental rethinking of how electricity is produced and distributed across North America.
