Renewable energy production in Germany doesn't really ever exceed the demand. The big problem is, that nuclear and coal power plants are very slow to change their output, so there are often situations, where they are producing electricity that is not needed. As in the last year, both nuclear and coal production has been reduced (a nuclear powerplant was shut down for good, coal got more expensive due carbon certificates) the amount of overproduction was reduced.
