I think a part of it is waiting for the point of time when overproduction from renewables is to the point that we regularly hit 0 (or negative) prices for some parts of the day. Then you basically only run it during those times when electricity is almost free. This is already happening on windy days in the summer in northern Europe (Finland and northern parts of Sweden/Norway).
