This report was authored by Energy+Environmental Economics (E3) and published in May 2021. This report explores novel tariff designs that leverage active vehicle-grid integrations and electric vehicle charging aggregators to provide enhanced charging profiles that would benefit utilities, ratepayers, and drivers. The report presents a simulation for California that indicates moving from basic flat rates to time-of-use (TOU) would provide a 116% increase in net savings for drivers but may present other complications with the introduction of a secondary peak load. The report continues on to explore the inclusion of aggregators who can actively manage the charging for several thousand chargers, ensuring the best price for the drivers, better utilization of the grid, and more flexible tariff schemes along with the utility to better match the operating costs.
