ELI5: How can power grids deal with the massive draw once power is restored after an outage? explainlikeimfive

We just had a transformer blow which cut power to around 1000ish people. Once they got the transformer fixed, presumably everyone's heater, refrigerator, freezer, etc would all start up at the same time. How can the power grid cope with that much draw all at once?

Edit: Local power grid, not on the national or even state scale.
