Ditto said the main choke point is the specialty steel used in transformers — there is only one U.S. manufacturer for that. Her group and the National Rural Electric Cooperative Association asked the Energy Department in May to suspend a 2016 efficiency standard that they say is partly responsible for the steel shortage, but the department has not gone along.
Last year, after the tornadoes in Mayfield, KY, the local power distribution companies faced shortages of the pole top transformers used to deliver household voltage to their customers. TVA took several dozen of the potentially damaged ones, tested, and rebuilt the ones that could be, so that they were able to be returned to service.
I can’t recall the success rate, but if an entity has transformer repair/maintenance facilities available, they could perform this assessment/repair service.
Florida Power & Light also suffered severe damage to multiple substations. Far beyond repairimg felled power lines.
