Large power transformers, 2010 baseline: DOE 2014 study

In 2010, large power transformers took 5 to 12 months from order to delivery from US plants and 6 to 16 months from foreign plants.

“The pre-shortage baseline comes from DOE's 2014 study, drawing on USITC trade-case data: in 2010, the average lead time between an LPT order and delivery ran 5 to 12 months for domestic producers and 6 to 16 months for foreign ones, stretching toward 18 to 24 months in high-demand periods.”
