Vehicle to Grid and Energy Storage System Tariffs


On December 1, 2023, the Commission issued an order in Case No. U-21297 that stated, among other things,
“The Commission agrees that a tariff is needed for V2G and storage resources; however, the Commission is not convinced that any of the options available on the record—the full retail rate proposed by MEIU, the DG outflow rate proposed by the company, or a DR tariff proposed by the Staff—represent an appropriate compensation mechanism for the outflow from energy storage systems and V2G-enabled vehicles. As such, the Commission believes that the most appropriate approach for developing appropriate tariff mechanisms for energy storage and V2G systems is through a workgroup that can better evaluate the three options proposed in this proceeding and other potential compensation frameworks.  The Commission thus directs the Staff to convene a stakeholder workgroup to develop tariff options for stand-alone storage and V2G no later than May 1, 2024.”
