Transformer lead‑times hit five years
Bloomberg reporting shows the U.S. AI data‑center boom has created electrical bottlenecks—transformer lead times have stretched as long as five years and the market leans on a few Korean suppliers like LS Electric amid export limits on Chinese firms. That kind of supply squeeze can delay big, high‑capacity installs and push customers toward phased or interim solutions. (x.com)
Wood Mackenzie data compiled in a U.S. government NIAC/CISA briefing shows transformer procurement times rose from about 50 weeks in 2021 to roughly 120 weeks on average by 2024, with large substation and GSU units stretching to 80–210 weeks. (cisa.gov) Wood Mackenzie and Wood Mackenzie commentary quantify the pressure on lead times and prices, noting average lead times of ~115–130 weeks and that the largest units are taking multiple years to deliver, forcing project schedules to be re-sequenced. (woodmac.com) Bloomberg’s feature points to concrete project impacts — the Abilene, Texas hyperscale campus tied to OpenAI is slated to draw about 1.2 GW and Bloomberg reports nearly half of planned U.S. data-center projects face delays or cancellations amid equipment scarcity. (bloomberg.com) South Korean manufacturers — LS ELECTRIC, HD Hyundai Electric and Hyosung — have captured major North American orders as U.S. domestic capacity lags; LS ELECTRIC disclosed contracts beginning 2026 and a $312m 525 kV deal with deliveries scheduled 2027–2029 and a backlog topping multiple trillion won.
