If it’s in the NE or North, that does not surprise me.
There has been a transformer shortage for the past 5 years at least, almost all sizes nationwide.
It’ll take another decade to upgrade and get the NE/North up to code & modernized I’d imagine with electricity and gas.
I work with 4,160 Volt transformers at work. We have a few that blow every time we have a scheduled maintenance outage. They are so old the windings insulation has deteriorated. The cold outage lets ambient moisture accumulate inside. Then when we power back up the moisture becomes steam with no way to escape until it does violently and kaboom! Sounds like a bomb going off. Our lead times on replacements is about six weeks.
