US transformer supply and lead times
A 2023 US Government Accountability Office report documented longer delivery times for large power and distribution transformers and heavy reliance on imports.
- Type
- Reported constraint
- Where it sits
- Long transformer waits can delay grid connection for new data centres, so they affect when announced capacity can actually come online.
- Constraint
- The GAO reported lead times lengthening to years for some utilities, and said over 80 percent of large power transformers used in the US in 2019 were imported (GAO-23-106180, August 2023).
What we checked
- One large utility told the GAO its transformer lead times had moved from 12 to 18 months to 18 to 36 months. (source)
- The report cites a 2020 Commerce Department finding that more than 80 percent of large power transformers used in the US in 2019 were imported. (source)
