You may have read that Germany needs lots of coal plants, should build lots, or even is building, but in fact that isn't so.

There are lists on the German wikipedia of the coal plants being built/replaced/renovated. There are some small coal plants being built and mostly replacing older small plants at the same location. I don't understand either why they're being built or why the older plants were there, but who cares, they're small. And there's a single big plant being built. Perhaps. The company that's building it doesn't seem to be in a hurry to complete construction.

No matter how to assign output and add up the possible capacity, it's not enough to replace even a single nuclear plant.
