The transformer shortage, in numbers.
Last updated July 2026.
Wood Mackenzie estimates a roughly 30% shortfall in power transformers and 10% in distribution units across the national fleet, with the situation projected to worsen through 2026 as data centers, EV charging buildout, and manufacturing expansion compete for the same limited supply. Lead times now run 30–50 weeks for distribution transformers and up to four years for larger power transformers. Prices are up 45–95% across transformer classes since 2019. More than half of the roughly 40 million distribution transformers in service are already past their expected service life, adding replacement demand on top of new-load demand.
This is the backdrop for why used and surplus pad-mount transformers — not just new builds — have become a real sourcing option. See our current inventory or read the FAQ for more.
