Earlier quoted context omitted.
Germany is not building new coal plants so they are not going to burn more coal because of EVs. EVs indeed create more demand for electricity, which is met by deploying more clean energy. Coal plants stopped being a good option economically decades ago and we are now getting to the point where keeping the existing plants going is also no longer economical. Gas plants are following pretty soon as well.
why do you think gas plants will be turned off, especially given the low gas prices?
So, if you are planning a gas plant that needs to be operational for decades, the economic outlook is pretty grim. That's why lots of plans for new gas plans are getting shelved.
Existing plants run quite economically. But when cheaper clean energy becomes available at scale, it becomes more expensive to operate them. Selling expensive energy during low demand is not going to be an option because cheaper energy will be preferred. Spinning plants up during peak demand takes time and battery + solar is already cheaper and faster for that as well. A gas plant that isn't running part of the time is going to be more expensive. That's why a lot of them will be taken out long before their planned end of life.
Currently people are shutting down the most expensive plants first (nuclear & coal) but once that is gone, gas will be next.
