This is one of the reasons why utilities generally haven't been too
thrilled about being required to pay going rates for customer-generated
power.  The power isn't necessarily there when they need it, so it's
not as useful as power they can generate on demand.  Solar power is
particularly bad this way in cold climates, and wind power in warm
climates:  the conditions which tend to produce maximum power demand
also tend to minimize contributions from these sources.

Peak-vs-average is definitely a major headache for utilities.  I saw an
amusing example of this cited some years ago.  Some of the happiest
power-plant managements in the world are the ones around Oak Ridge,
Tennessee.  The isotope-separation plant there is enormous -- whole
power plants were built because of it -- and it runs 24 hours a day.
The load fluctuations from the town of Oak Ridge are negligible by
comparison.
