We have a lot of good technologies already, the problem is they just don't scale well.
I can envision older warehouses in an industrial district being converted in to vacuum flywheel storage sites where power fed in to the grid earlier is buffered and then released back to it.
Changing our culture is another possible approach. Power is used in the evenings because that's when most people get off work/home/etc and they tend to have /that/ time to do cooking and cleaning (thermal cooling / heating are more solvable with changes in materials and building shape than culture change).
