Those same wealthy folks will install a battery component (just because they can) and will pay their own cost to produce have about the same effect as retail consumption/production. Tying fixed costs (infrastructure) to variable costs (power production) will always favor one group or another. Low consumers infrastructure costs are subsidized by higher consumers. It costs just as much to provide the grid access for 1 KWh/day as it does for 100 KWh/day.
