Steam plants fired by coal takes hours to warm through before one can apply high loads. Gas plants are much quicker but both are dinosaurs to hydro electric pump storage and battery station supplied power from wind, solar and nuclear plus interconnector power from other countries who are already in surplus much of the time.

 

 A typical coaler only takes many hours from flat cold, They were all designed to base load and run all the time which they did for much of their lives

 

In my time at Eggborough from 2005-2018 the market had changed and as such they used to ‘2-shift’ so they came on in the morning and off in the evening leaving them hot pretty much all the time ready to load up in 85 minutes IIRC. Remember these plants and CCGTs are not standby plants and are mostly running on planned runs anyway. 
 

A CCGT can create some load at very short notice but it too has a steam turbine to warm though albeit a much smaller one.  Our new plant has lots of electrical heating on the steam chests though and that can come up in load ridiculously fast.

      Unless you are on a decent FiT then at the moment it makes financial sense to send everything you produce back to the grid, then charge your batteries overnight at less than half the cost your energy
