Anthropic bought commitments for 1.7 gigawatts of heavy-duty generators for $3.4bn from OnePWR Solutions in late September. The deal is the largest known single purchase of power-generation equipment by an AI lab.
Why it matters
Lead times for gas turbines and generators now stretch years into the future, so securing equipment early has become a competitive advantage for AI developers. The purchase highlights the enormous energy demands of AI infrastructure.
Anthropic acquired commitments for 1.7 gigawatts of heavy-duty generators, a capacity that rivals a meaningful share of a large power plant. The deal includes engineering and construction capabilities needed to install the equipment.
The players
Anthropic
Anthropic is an artificial intelligence company that develops the Claude family of large language models.
OnePWR Solutions
OnePWR Solutions is an equipment supplier based in San Antonio, Texas that sells power-generation hardware.
The details
Anthropic took over OnePWR's existing Caterpillar generator orders rather than becoming a customer of the company, and no OnePWR employees transferred to Anthropic. The deal secured engines ordered years earlier before prices surged, and OnePWR needed financing to complete the transaction.
Timeline
OnePWR ordered Caterpillar generators in 2024.
Anthropic bought the generator commitments in late September 2026.
The Tech Race
Anthropic's generator purchase follows xAI's $2bn mobile gas turbine buy earlier this year, part of an arms race among AI labs to lock in scarce power supply. Alphabet's late-2025 acquisition of energy developer Intersect shows the same push to control energy assets directly.
Heavy power demand from AI data centers can influence the cost and reliability of electricity for households and businesses in the regions where these facilities are built. Securing dedicated generation reduces the risk that AI projects are delayed by equipment shortages.
The takeaway
Power supply has become a central constraint on AI development, and companies are now buying generation capacity years in advance. Readers tracking AI costs should watch how these energy commitments affect electricity markets.
