Right, but power companies likely hold enough for a year's worth of natural disasters + a 10-20% cushion. Sabotage can be a lot more destructive than random failure.
I think you're basically agreeing with what I'm saying. Small scale localized disasters aren't going to take a year to repair because companies keep some repair stock on hand or have replacements in the pipeline for existing equipment. It's only when we get to disasters that threaten to completely deplete repair/reserve stocks that the 1 year wait time for new grid scale transformers becomes truly concerning.
