FT: AI Data Center Boom Blows Out Power Transformer Lead Times From Months to 4-5 Years — Half of 2026 US Capacity at Risk of Delay

FT reports large power transformer lead times have stretched to as long as 4-5 years (~128 weeks average, 144+ for generator step-up units) as AI data center demand collides with a stagnant global supply base, with US prices reportedly up ~79%. Coverage estimates roughly half of the ~12 GW of US data center capacity planned for 2026 is at risk of delay or cancellation, with only ~4-5 GW under active construction, prompting responses like Hitachi Energy's $457M Virginia transformer factory.
