This also applies to natural gas, which is a much bigger deal. The title here didn't say that, but the article's title did.

I thought they'd softened this so it didn't apply to any existing gas plant? Did they change that again?

Yes, I see that's the case. I imagine that's because of all the existing combined cycle plants. The new rule also doesn't apply to peaker plants.

The folks with the Allam cycle patents must be happy about this.

Peaker plants are not cost competitive with utility scale battery storage, storage which is currently supply constrained.

They're not cost competitive with batteries for diurnal storage, but they are competitive for low duty cycle demand on much longer time scales (like covering Dunkelflauten).

Natural gas emits less than half the CO2 of coal per unit of energy due to its chemical makeup, NG is the "cleanest" fossil fuel.

If you count the leaks then the numbers are not that good.
