It is pretty average that they didn't discuss the fact that the peaking power plants are very expensive, typically burning higher grade fuels like natural gas or diesel, rather than goal or nuclear. And, rather than encourage old style night time off-peak use, we need charging to occur during solar PV peak on colder days, and cars (mobile batteries) to supply to the grid during peak summer load, providing grid stabilisation to account for wind/PV variability.
