Fossil and nuclear plants routinely run at 90% of nameplate capacity. If a gas plant is down more often than that, it's because that plant is a peaker, which exists to make up for things like, say, the wind dying down.
I'm sure there's a somewhat tedious discussion to be had about how France's recent adventures with their decaying nuke plants affect that 90%. Have at it if this interests you.
