It seems to be reducing the on-peak usage and leveling out power usage spikes, but it appears to only arbitrage energy generated with solar power. I dont think theyre yet allowing the discharge of energy to the grid that was charged using off-peak grid energy.
Does this mean you are not being allowed to sell excess electricity back to the electric company?
It was my impression (based on newspaper reports) that power companies were required to buy back excess electric production via solar (and other "green" methods) in your part of the country.
