I must assume that people with this level of investment have thought of this but, today in many places overnight energy costs are low. Given the trajectory of wind costs and deployment, this seems only likely to continue. So where are the sums for running the system off behind the meter solar when the sun shines, pausing production for a few hours as net load peak occurs, then starting again with grid supplied off peak overnight power? I think a naive conparison would be misleading as low rates at night for consumers are often accompanied by slightly higher prices during the day to nudge usage out of peak times, but I'd assume there's still some saving to be made.
