Current numbers
~128–208 wkHV/substation power transformer lead time (standard); up to ~60 months in constrained markets — often the schedule's long pole
~128–208 wklarge power transformer lead time (GSU ~144–208 wk); up to ~5 yr in constrained markets — the schedule-dominating long pole
~128–208 wkHV/substation transformer lead time (GSU ~144–208 wk; up to ~60 mo constrained) — OFE-by-default, pre-GC
