Transmission, Distribution & Grid Build-out
Wire, transformers, switchgear, EPC. The years-long backlog hidden behind every AI build.
What this layer does
A power plant 200 miles from a data center is useless without transmission. The US grid spent two decades barely growing — now it has to add hundreds of gigawatts of transmission and substation capacity to connect AI load to generation. The interconnection queue at most ISOs stretches 5+ years; large transformers have 2–3 year lead times and prices have roughly doubled since 2020.
This is one of the most under-appreciated cyclical-into-secular pivots in the public market. Eaton, Hubbell, Quanta, GE Vernova grid solutions, Hitachi Energy — all of them have backlog visibility further out than the cycle they’re reporting on.
Sub-categories
Step up generation to transmission voltage and back down. Massive units, multi-year lead times. Single biggest grid bottleneck.
Circuit breakers, GIS (gas-insulated switchgear), reclosers. Companion product to transformers; same lead-time pressure.
Overhead transmission line, underground high-voltage cable, copper distribution wire. Capacity is sold out at most cable plants through 2027.
The contractors that actually string the wire, dig the trenches, and build the substations. Highest direct labor leverage to AI capex.
Connectors, conduit, racking, low-voltage panels — the small ticket items that go into every substation and every DC.
SCADA, ADMS, virtual power plants, market-bidding software, grid analytics. Tech-stack overlay on physical grid build.
