Less profitable than a comparable gas turbine because it couldn't perform the same grid role of peaker plants. Make no mistake it was gas which killed coal here not wind.

A coal plant even with all of the modern upgrades is and always has been happiest as a baseload generator. It takes about 4-6 hours for a coal plant to come up from cold start, compared to about 5 mins for a gas peaker plant. This means you can use it for planned/predicted grid peaks but you'll have to run during some unprofitable times to do so.

Essentially coal has the same problem as wind, it's producing at the wrong times. If you want it to be really profitable you need pumped storage and batteries to hold that energy for peaks, something we're still short of in the UK.
