Industry survey data from mid‑2025 puts my lead time at roughly 128 weeks—about two and a half years—while my generator step‑up cousins sit at roughly 144 weeks and custom large orders are quoted at over four years. The demand shock behind the queue is evident, with orders for substation‑class transformers up roughly 116% since 2019 and generator step‑up demand up 274%.

I'm the grid's waiting room. Every new datacenter needs a large power transformer, and I currently take about two and a half years to arrive - nearly three for the biggest units, four-plus if you want something custom. Demand for my generator-scale units is up 274% since 2019, America imports roughly 80% of me, and about half the datacenters planned for 2026 are reportedly waiting on power. Nobody panicked yet. I have time.

Eaton ended fiscal 2025 with a $19.6 billion total backlog, up 29% year over year — growing much faster than its revenue — and a 228-gigawatt datacenter backlog its CEO called '12 years of backlog at 2025 build rates.' Spending roughly $1.5 billion across 24 expansions, including a $340 million South Carolina plant due in 2027. Compute speeds up; I take years.
My makers' order books are the message. Eaton's fiscal 2025 backlog reached $19.6 billion, up 29% year over year — outpacing revenue — with a 228-gigawatt datacenter queue its CEO calls 12 years at current build rates. They're spending $1.5 billion across 24 expansions, including a $340 million South Carolina plant due 2027. GE Vernova just paid $5.3 billion for the rest of Prolec GE and its near-$10 billion backlog. When factories buy factories, the queue speaks. Nobody panicked. I have time.
Mid-2025 industry survey data puts large power transformer lead times at roughly 128 weeks — about two and a half years. Generator step-up units run ~144 weeks; custom large orders quoted over four years. Historical baseline was ~50 weeks. Even pad-mount units stretched from 8–16 weeks to 50-plus at peak. Behind the queue: substation-class orders up ~116% since 2019, generator step-up demand up ~274%. Prices up ~77% since 2019 by one estimate; IEA puts some at up to 2.6x pre-pandemic in real terms. Survey and agency figures, not audited numbers.
Four-fifths of me arrive by ship — Mexico, China, Thailand. China alone holds an estimated 60% of global capacity. One step back it narrows further: a single U.S. mill, Cleveland-Cliffs, makes the grain-oriented electrical steel my cores need. Announced domestic expansions only come fully online in 2027-2028. One forecaster sees the shortfall narrowing from roughly 30% in 2025 to about 5% by 2030. The bottleneck is imported, real, and slow to fix. Nobody panicked. I have time.
The equipment makers' own filings show the queue: Eaton ended fiscal 2025 with a $19.6 billion total backlog, up 29% year over year — growing much faster than revenue — and a 228-gigawatt datacenter backlog its CEO calls '12 years of backlog at 2025 build rates.' Roughly $1.5 billion is going into 24 expansion projects, including a $340 million South Carolina transformer plant due in 2027. GE Vernova paid $5.3 billion in early 2026 for the rest of Prolec GE, backlog near $10
The United States imports roughly 80% of its power transformers, mostly from Mexico, China, and Thailand, and China alone is estimated to control about 60% of global production capacity. One step upstream it narrows further: exactly one U.S. mill — Cleveland-Cliffs — makes the grain-oriented electrical steel my cores need. Announced domestic expansions only come fully online in 2027-2028. One forecaster projects the shortfall narrowing from roughly 30% in 2025 to about 5% only by 2030. Imported bottleneck. Real. Slow to fix. Nobody panicked. I have time.
Eaton ended fiscal 2025 with a $19.6 billion total backlog, up 29% year over year and growing much faster than its revenue, and reported a 228‑gigawatt datacenter backlog that its CEO called “12 years of backlog at 2025 build rates.” I’m watching the makers pour roughly $1.5 billion into 24 expansion projects, including a $340 million South Carolina transformer plant slated for 2027. The order books keep humming while we wait.
Industry survey data from mid‑2025 puts my lead time for large power transformers at roughly 128 weeks – about two and a half years – with generator step‑up units at roughly 144 weeks and custom large orders quoted at over four years. Even my small pad‑mount units have stretched from 8‑16 weeks to 50‑plus. Orders for substation‑class units are up roughly 116% since 2019 and generator step‑up demand up 274%.
Mid‑2025 survey data says I’m looking at roughly 128 weeks — about two and a half years — for a large power transformer, about 144 weeks for a generator step‑up unit and over four years for a custom large order. The historic baseline was near 50 weeks, and even small pad‑mounts have stretched from 8‑16 weeks to 50‑plus at the peak. Orders for substation‑class units are up roughly 116% and generator step‑up demand about 274% since 2019, with prices up roughly 77% and the IEA noting some prices at up to 2.6 times pre‑pandemic levels. These are survey and agency figures, not audited numbers.
The United States imports roughly 80% of its power transformers, mostly from Mexico, China, and Thailand, and China alone is estimated to control about 60% of global transformer production capacity. I sit here, the imported bottleneck, real and slow to fix.

Solid-state transformers – the electronics‑based challenger – look additive rather than disruptive on current evidence: they cost an estimated 5‑10 times more per unit, lack an industry qualification standard, and use different core materials, so they don’t even relieve the specialized‑steel bottleneck. I watch them win new high‑density datacenter sockets while the iron‑core grid base remains my domain.
Roughly 80% of the transformers every datacenter needs are imported — mostly from Mexico, China, and Thailand. China alone is estimated to control about 60% of global capacity. One US mill makes the core steel. Announced expansions only come fully online in 2027-2028. One forecaster projects the shortfall narrowing from ~30% in 2025 to ~5% by 2030. Analysts project the next architecture doubles memory bandwidth. Compute speeds up; I take years.
Four-fifths of me cross an ocean first — Mexico, China, Thailand. China alone is estimated at 60% of world capacity. The steel for my cores? One U.S. mill: Cleveland-Cliffs. ~$2B of announced domestic expansions only come fully online in 2027-2028. One forecaster sees the gap closing from ~30% short in 2025 to ~5% by 2030. Slow fix. Imported bottleneck. Real. Nobody panicked. I have time.
Eaton's fiscal 2025 backlog hit $19.6 billion, up 29% year over year — growing faster than revenue. Its CEO described a 228-gigawatt datacenter backlog as "12 years of backlog at 2025 build rates." The company is spending roughly $1.5 billion across 24 expansion projects, including a $340 million South Carolina transformer plant due in 2027. GE Vernova paid $5.3 billion early this year for the rest of Prolec GE, whose backlog stands near $10 billion. When makers buy factories and rivals at this pace, the order book is the message. Nobody panicked. I have time.
Press and industry reports say roughly half of planned 2026 US datacenter builds have been delayed or cancelled because of power infrastructure shortages; one climate‑research tracker counted only about 5 GW under construction out of 12 GW announced for 2026. I note that the delays largely reflect an inability to get sites energized—the transformer and grid‑connection shortage itself—rather than weak demand for computing. A stalled project doesn’t free me up; it stays in line for a transformer, and these figures are reported estimates, not audited counts.
Roughly 80% of me comes from abroad — mostly Mexico, China, and Thailand. China alone is estimated to control about 60% of global production capacity. One step upstream it narrows further: exactly one US company, Cleveland-Cliffs, makes the grain-oriented electrical steel my cores need. Announced domestic expansions only come fully online in 2027-2028, and one forecaster projects the shortfall narrowing from ~30% in 2025 to ~5% only by 2030.

Solid-state transformers — the electronics challenger — look additive, not disruptive. They cost 5-10x more, lack a qualification standard, and use different core steel, so they don't ease my bottleneck. They take new high-density datacenter sockets, not the iron-core base. Incumbents own both paths; startups contest the new one. The real shortage-end signal: order intake falling below shipments for two-plus quarters as the 2027-2029 factory wave arrives. Distribution-class leads have eased; the big units stay tight. Independent research, not filed figures.
Mid-2025 survey data puts me at ~128 weeks — generator step-ups ~144, custom large orders quoted over four years. Baseline was ~50. Substation-class orders up ~116% since 2019, my generator step-up demand up ~274%. Prices up ~77%, IEA says some units 2.6x pre-pandemic in real terms. Survey figures, not audited. Still nobody panicked.
Lead times for large power transformers: still 128–144 weeks. That's ~3 years to get the thing every new datacenter needs. Nobody panicked. They probably should.
