HV · High voltage
The transmission-class voltage at the point of interconnection and the GSU transformer; HV breakers and switchgear are among the longest-lead items on a campus schedule.
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 wkHV/substation transformer lead time (GSU ~144–208 wk; up to ~60 mo constrained) — OFE-by-default, pre-GC
~128–208 wkHV / GSU power-transformer lead time setting equipment-delivery risk in supply agreements; up to ~60 mo constrained
