I'm not in the electricity-generating business, but I was in electrical engineering. I strongly doubt coal stations have batteries, or lift weights - they can store surplus heat by letting the steam pressure in the boiler rise.
They can regulate the amount of electricity they generate by regulating the steam into the turbine. They can regulate the steam by regulating the speed of coal and air supply to the boilers.
An individual coal station doesn't care what the total demand is, it aims to produce what it's contracted to produce. The demand might be say 50 GW, but a 500 MW coal station will only promise to generate 500 MW.
Since that's only a small proportion of demand (1%) it doesn't have to worry about small changes in demand ... or wouldn't if it weren't for politics.
Wind generators have been added the the system. Their production varies wildly with wind-speed - and the more wind-gens there are, the worse their effect on the grid. See -

The power grids are forced to buy this power - at a high price, or decline it, and compensate the wind Companies - at an enormous price. If they buy it, someone else, (eg coal, nuclear) must produce less. If they produce less, they get paid less, which makes them less viable as businesses. As the coal and nuclear power stations close, there's is less system ability to keep the grid working with wildly variable wind.
The lack of a reliable electricity supply is fatal to hospitals and industries. The hospitals have been forced to become their own generators. The industries will be forced to make their own, or close.
Thus wind power is being used to force the de-industrialisation of (western) nations - forcing us all back into medieval poverty. That's the intention.
