(1) An electric utility regulated by the utilities and transportation commission under this chapter may submit to the commission an electrification of transportation plan that deploys electric vehicle supply equipment or provides other electric transportation programs, services, or incentives to support electrification of transportation. The plans should align to a period consistent with either the utility's planning horizon under its most recent integrated resource plan or the time frame of the actions contemplated in the plan, and may include:

(a) Any programs that the utility is proposing contemporaneously with the plan filing or anticipates later in the plan period;

(b) Anticipated benefits of transportation electrification, based on a forecast of electric transportation in the utilities' service territory; and

(c) Anticipated costs of programs, subject to the restrictions in RCW 80.28.360.

(2) In reviewing an electrification of transportation plan under subsection (1) of this section, the commission may consider the following: (a) The applicability of multiple options for electrification of transportation across all customer classes; (b) the impact of electrification on the utility's load, and whether demand response or other load management opportunities, including direct load control and dynamic pricing, are operationally appropriate; (c) system reliability and distribution system efficiencies; (d) interoperability concerns, including the interoperability of hardware and software systems in electrification of transportation proposals; and (e) the benefits and costs of the planned actions.

(3) The commission must issue an acknowledgment of an electrification of transportation plan within six months of the submittal of the plan. The commission may establish by rule the requirements for preparation and submission of an electrification of transportation plan. An electric utility may submit a plan under this section before or during rule-making proceedings.

(4) The commission may require a large combination utility as defined in RCW 80.86.010 to incorporate the requirements of this section into an integrated system plan established under RCW 80.86.020.
