Load-serving HV/substation power-transformer lead time (~128 wk average power transformer per Wood Mackenzie Q2 2025; large-unit quotes have ranged ~80–210 wk; up to ~60 mo in constrained markets) — the schedule-dominating long pole. Generator step-up units are the separate GSU claim.

| Value kind | observed — Reported measurements, counts, and specifications keep the precision and scope stated by their source; an exact specification is not treated as a range. |
|---|---|
| Scope | Load-serving substation/power transformers only. Generator step-up (GSU) transformers are carried as a separate register entry (~144–208 wk). The upper bound comes from large-unit and constrained-market quotes, not from GSU indices. |
| Caveat | Indices diverge in mid-2026 for large power transformers generally; the GSU-specific divergence (VAWN 144 wk vs SemiAnalysis 3–4 yr) is recorded on the GSU claim. |
