Utility Electrification Plans and Return on Investment Authorization

Utilities are authorized to submit transportation electrification plans that deploy electric vehicle (EV) chargers or programs and incentives that support transportation electrification. Additionally, utilities may petition the Washington Utilities and Transportation Commission (UTC) for a rate of return on EV chargers installed for the benefit of ratepayers through December 31, 2030. The UTC may approve an additional 2% to the standard rate of return if the utility installs EV charging stations on a fully regulated basis similar to other capital investments behind a customer’s meter, and the expenditures do not increase ratepayer costs more than 0.25%. EV charging stations are subject to a depreciation schedule and may be gifted to the customer when fully depreciated. The UTC issued a report on the use and impacts of the incentive in 2017.
