Utilities may petition the Washington Utilities and Transportation Commission (UTC) for a rate of return on EVSE 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 EVSE 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%. EVSE 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 on December 1, 2017.
