So capacity of fossil fuels went up, but I suppose natural gas shuts down while renewable generation is high so it doesn't use its capacity all the time - my bad
Yes, the easiest way to get a stable grid with wind and solar is to have natural gas capacity equal to what you need from wind and solar. Gas is not used when there is wind or solar, and is very easy and quick to turn on when needed.
In the future when more green gasses become available, bio methane, hydrogen or syn methane, those gas plants can be filled with those as well.
