The reason why they aren't much of a problem for the grid is solar. Right now we already have the issue, that in some areas we're throwing away the majority of the produced electricity. Very common in e.g. southern germany. Conveniently, cooling is especially needed when the energy production from solar is at its maximum. I've been part of projects building 20-40 MW solar installations in southern germany and on average we throw away >50% of what we generate. There is SO MUCH SOLAR now, we don't know what to do with all the energy.
