Tony Seba was right, Households will produce more energy than they use. The rapid growth of rooftop solar combined with battery storage will cause the demand for electricity to drop. This rooftop solar is generated *behind the meter* where it is not accounted for by the utilities.
The battery storage will be able to join a VPP – virtual power plant, which can supply energy to the grid when the demand peaks. In addition the EVs will be capable of V2G – vehicle to grid – also to supply energy when demand peaks.
