Anything that can't help black start the power grid isn't ice age proof.
Natural gas lines will hydrate plug in the cold so thats no good.
Coal plants need a natural gas and a few megawatts of electricity to get blowers going, pumps going so the boiler can warm up. So they're no good unless they have oil fired backup boilers and enough diesel generators that can power the small boilers and pumps and blowers for the big boilers.
Wind and solar won't connect unless there's a stabile grid connection so they're useless.
Most Nuclear plants want to run at full power, so they can't black start. The only ones that can run at partial power are ones that run highly enriched fissile fuel such as subs and aircraft carriers.
Some 3% enriched boiling water reactors will run at partial power I doubt they can black start, they may island them selves in a large outage.
Hydro electric can black start the grid.
