a big 2GW coal plant presumably needs the same capacity available on standby in case there is a production or transmission failure in that plant, yet you never hear the argument about backup costs made about coal-fired power, because the power system has long been designed to cope with such needs.

I think about half of the swedish nuclear power was offline at the same time last year which led to higher prices, imports and some backup plants being used (at least one oil-fired iirc).
