Neat reference. I agree with you on CTs. The original poster suggested two things: solar is not responsive to demand and that coal plants are responsive. My response is intended to be narrow to those points: coal plants don’t really produce on an instantaneous demand signal any more than solar or wind. Coal produces at some amount and then ramp up or down based on a longer-horizon demand signal (e.g., a 5-min Grid solution). Wind and solar can’t ramp up but they can dispatch down on the same signals. My other point is that solar generally matches peak demand pretty well so you don’t need a ton of demand responsiveness (given that electricity demand is already inelastic).
