Washington Utilities and Transportation Commission
The UTC regulates the investments of utility companies that already fall under our jurisdiction. Regulated electric utilities may offer battery charging facilities using ratepayer funds subject to the commission's approval (RCW 80.28.320). The UTC does not regulate electric vehicles, or private chargers owned by a private company such as a gas station or store.
In 2017, the commission issued a policy and interpretive statement about the regulation of electric vehicle charging stations.
The policy statement considered key elements concerning the regulation of EVSE and addressed additional policy considerations and requirements to ensure that utility participation in the electric vehicle charging market is in the public interest.
The commission can authorize an incentive for electric utilities on capital expenditures for electric vehicle supply equipment (EVSE) through 2030 (RCW 80.28.360).
Utilities may seek an incentive rate of return of up to 2% for EVSE behind the meter. The investments cannot increase the retail revenue requirement of the utility more than 0.25% (after offsetting revenue).
In 2019, the Legislature authorized regulated investor-owned utilities to submit an electrification of transportation plan that deploys EVSE or provides other electric transportation programs, services, or incentives to support electrification of transportation (RCW 80.28.365). The plan may include:
The commission expects to see some of the utilities to file their first plans in 2020.
