WAC 480-96-010

The purpose of these rules is to ensure that a large combination utility meets the clean energy transformation standards summarized in WAC 480-100-610 and the requirements of chapter 80.86 RCW in a timely manner and at the lowest reasonable cost. Pursuant to RCW 80.86.020 (2)(a), the commission consolidates the following planning and reporting requirements into an integrated system plan: Renewable portfolio standard reports, electric integrated resource plans, gas integrated resource plans, and clean energy implementation plans. Other plans listed in RCW 80.86.020 (2)(a) are not required to be consolidated into an integrated system plan, but interested parties, or the commission on its own motion may petition the commission to consolidate these plans with the ISP. Unless otherwise ordered by the commission, a large combination utility may choose to file an electrification of transportation plan as part of the ISP or separately. The statutorily required contents of any plan consolidated into an integrated system plan must be met by the integrated system plan.
