The second edition of this informative document by Jim Lazar details a variety of different techniques which could be applied to the California "duck-shaped" net electricity load curve after subtracting the average renewable generation. Prior to application of the techniques there is an early evening peak, but Jim conservatively shows that the net load can be smoothed - thus resembling the profile of a duck in flight - hence the title. See Teaching the Duck to Fly. Techniques vary from demand response to deliberately selecting and rewarding renewable power sources that generate late afternoon (e.g. west-facing non-tracking solar PV panels or tracking solar panels). One surprise is that water pumping represents 7% of USA electricity load and higher in California, and most of this can be rescheduled outside evening peak hours, or Smart-grid controlled.
