Berkeley Lab – A Snapshot of EV-Specific Rate Designs Among U.S. Investor-Owned Electric Utilities

EV-specific electric utility rates have a profound effect on the underlying economics motivating EV adoption. State utility regulators and electric utilities play a critical role in approving and designing rates, respectively. However, the nascence of the EV industry has resulted in regulators’ and utilities’ having very limited experience with EV-specific rate designs. This suggests there could be substantial benefit from efforts intended to provide a better understanding of how EV-specific rates are designed presently in the United States. To meet that need, Berkeley Lab researchers, with support from E9 Insight, developed a database of piloted, proposed, and offered rates among U.S. investor-owned utilities (IOUs) between 2012 and 2022. The database is comprised of 217 electric utility retail rates from IOUs in 38 states and the District of Columbia that either required proof of EV ownership or were otherwise designed for the purposes of reselling energy for use in EV charging (i.e., EV-specific rates). In this webinar, we will discuss the database and our analysis of it, which allowed us to identify the EV-specific rate designs currently observed in the U.S., to infer a number of policy-driven objectives based on those rate designs, and to suggest a number of next steps for future research.
