(1) The legislature finds that large combination utilities are subject to a range of reporting and planning requirements as part of the clean energy transition. The legislature further finds that current natural gas integrated resource plans under development might not yield optimal results for timely and cost-effective decarbonization. To reduce regulatory barriers, achieve equitable and transparent outcomes, and integrate planning requirements, the commission may consolidate a large combination utility's planning requirements for both gas and electric operations, including consolidation into a single integrated system plan that is approved by the commission. (2)(a) By July 1, 2025, the commission shall complete a rule-making proceeding to implement consolidated planning requirements for gas and electric services for large combination utilities that may include plans required under: (i) RCW 19.280.030 ; (ii) RCW 19.285.040 ; (iii) RCW 19.405.060 ; (iv) RCW 80.28.380 ; (v) RCW 80.28.365 ; (vi) RCW 80.28.425 ; and (vii) RCW 80.28.130 . The commission may extend the rule-making proceeding for 90 days for good cause shown. The large combination utilities' filing deadline required in subsection (4) of this section will be extended commensurate to the rule-making extension period set by the commission. Subsequent planning requirements for future integrated system plans must be fulfilled on a timeline set by the commission. Large combination utilities that file integrated system plans are no longer required to file separate plans that are required in an integrated system plan. The statutorily required contents of any plan consolidated into an integrated system plan must be met by the integrated system plan. (b) In its order adopting rules or issuing a policy statement approving the consolidation of planning requirements, the commission shall include a compliance checklist and any additional guidance that is necessary to assist the large combination utility in meeting the minimum requirements of all relevant statutes and rules. (3) Upon request by a large combination utility, the commission may issue an order extending the filing and reporting requirements of a large combination utility under RCW 19.405.060 and 19.280.030 , and requiring the large combination utility to file an integrated system plan pursuant to subsection (4) of this section if the commission finds that the large combination utility has made public a work plan that demonstrates reasonable progress toward meeting the standards under RCW 19.405.040 (1) and 19.405.050 (1) and achieving equity goals. The commission's approval of an extension of filing and reporting requirements does not relieve the large combination utility from the obligation to demonstrate progress towards meeting the standards under RCW 19.405.040 (1) and 19.405.050 (1) and the interim targets approved in its most recent clean energy implementation plan. Commission approval of an extension under this section fulfills the large combination utility's statutory filing deadlines under RCW 19.405.060 (1). (4) By January 1, 2027, and on a timeline set by the commission thereafter, large combination utilities shall file an integrated system plan demonstrating how the large combination utilities' plans are consistent with the requirements of this chapter and any rules and guidance adopted by the commission, and which: (a) Achieve the obligations of all plans consolidated into the integrated system plan; (b) Provide a range of forecasts, for at least the next 20 years, of projected customer demand that takes into account econometric data and addresses changes in the number, type, and efficiency of customer usage; (c) Include scenarios that achieve emissions reductions for both gas and electric operations equal to at least their proportional share of emissions reductions required under RCW 70A.45.020 ; (d) Include scenarios with emissions reduction targets for both gas and electric operations for each emissions reduction period that account for the interactions between gas and electric systems; (e) Achieve two percent of electric load annually with conservation and energy efficiency resources, unless the commission finds that a higher target is cost-effective. However, the commission may accept a lower level of achievement if it determines that the requirement in this subsection (4)(e) is neither technically nor commercially feasible during the applicable emissions reduction period; (f) Assess commercially available conservation and efficiency resources, including demand response and load management, to achieve the conservation and energy efficiency requirements in (e) of this subsection, and as informed by the assessment for conservation potential under RCW 19.285.040 for the planning horizon consistent with (b) of this subsection. Such an assessment may include, as appropriate, opportunities for development of combined heat and power as an energy and capacity resource, demand response and load management programs, and currently employed and new policies and programs needed to obtain the conservation and efficiency resources. The value of recoverable waste heat resulting from combined heat and power must be reflected in analyses of cost-effectiveness under this subsection; (g) Achieve annual demand response and demand flexibility equal to or greater than 10 percent of winter and summer peak electric demand, unless the commission finds that a higher target is cost-effective.
