Purpose of the Proposal and Its Anticipated Effects, Including Any Changes in Existing Rules: The proposed rules implement legislative changes made in 2017 and 2019 and streamline implementation of chapter 19.285
RCW. The proposed amendments modify or add definitions, incorporate language pertaining to energy assistance, change the manner in which utility low-income programs operate, amend the renewable portfolio standard compliance and reporting rules, and amend the energy and emission intensity reporting rules.
Reasons Supporting Proposal: The Washington legislature in 2019 passed the Clean Energy Transformation Act, which included among its provisions several amendments to EIA. The primary reason for this rule making is to codify these amendments in the current EIA rules in chapter 480-109 WAC. The rule making will also codify changes made in the 2017 legislative session through ESB 5128. Finally, the rule making will make a number of other amendments that help streamline the implementation of EIA.
Rule is not necessitated by federal law, federal or state court decision.

AMENDATORY SECTION(Amending WSR 15-07-043, filed 3/12/15, effective 4/12/15)
WAC 480-109-100Energy efficiency resource standard.
(1) Process for pursuing all conservation.
(a) Process. A utility's obligation to pursue all available conservation that is cost-effective, reliable, and feasible includes the following process:
(i) Identify potential. Identify the cost-effective, reliable, and feasible potential of possible technologies and conservation measures in the utility's service territory.
(ii) Develop portfolio.
Develop a conservation portfolio that includes all available, cost-effective, reliable, and feasible conservation. A utility must develop programs to acquire available conservation from all of the types of conservation identified in (b) of this subsection. The portfolio must include all conservation programs and mechanisms identified pursuant to RCW 19.405.120, which pertain to energy assistance and progress toward meeting energy assistance need, including the low-income conservation programs and mechanisms in subsection (10)(b) of this section.
If no cost-effective, reliable and feasible conservation is available from one of the types of conservation, a utility is not obligated to acquire such a resource.
(iii) Implement programs. Implement conservation programs identified in the portfolio to the extent the portfolio remains cost-effective, reliable, and feasible. Implementation methods shall not unnecessarily limit the acquisition of all available conservation that is cost-effective, reliable and feasible.
(iv) Adaptively manage. Continuously review and update as appropriate the conservation portfolio to adapt to changing market conditions and developing technologies. A utility must research emerging conservation technologies, and assess the potential of such technologies for implementation in its service territory.
(b) Types. Types of conservation include, but are not limited to:
(i) End-use efficiency;
(ii) Behavioral programs;
(iii) High-efficiency cogeneration;
(iv) Production efficiency;
(v) Distribution efficiency; and
(vi) Market transformation.
(c) Pilots. A utility must implement pilot projects when appropriate and expected to produce cost-effective savings within the current or immediately subsequent biennium, as long as the overall portfolio remains cost-effective.
(2) Ten-year conservation potential. By January 1, 2010, and every two years thereafter, a utility must project its cumulative ten-year conservation potential.
(a) This projection must consider all available conservation resources that are cost-effective, reliable, and feasible.
(b) This projection must be derived from the utility's most recent IRP, including any information learned in its subsequent resource acquisition process, or the utility must document the reasons for any differences. When developing this projection, utilities must use methodologies that are consistent with those used in the Northwest Conservation and Electric Power Plan.
(c) The projection must include a list of each measure used in the potential, its unit energy savings value, and the source of that value.
(3) Biennial conservation target. Beginning January 2010, and every two years thereafter, a utility must establish a biennial conservation target.
(a) The biennial conservation target must identify, and quantify in megawatt-hours, all available conservation that is cost-effective, reliable, and feasible.
(b) The biennial conservation target must be no lower than a pro rata share of the utility's ten-year conservation potential.
(c) Excess conservation. No more than twenty-five percent of any biennial target may be met with excess conservation savings allowed by this subsection. Excess conservation may only be used to mitigate shortfalls in the immediately subsequent two biennia and may not be used to adjust a utility's ten-year conservation potential or biennial target. The presence of excess conservation does not relieve a utility of its obligation to pursue the level of conservation in its biennial target.
(i) Cost-effective conservation achieved in excess of a biennial conservation target may be used to meet up to twenty percent of each of the immediately subsequent two biennial targets.
(ii) A utility may use single large facility conservation savings achieved in excess of its biennial target to meet up to five percent of each of the immediately subsequent two biennial conservation targets.
(iii) Until December 31, 2017, a utility with an industrial facility located in a county with a population between ninety-five thousand and one hundred fifteen thousand that is directly interconnected with electricity facilities that are capable of carrying electricity at transmission voltage, may use cost-effective excess conservation savings from that industrial facility to meet the subsequent two biennial conservation targets. For purposes of this subsection, transmission voltage is one hundred thousand volts or higher.
A utility retains the responsibility to demonstrate the prudence of all conservation expenditures, consistent with RCW 19.285.050
(5) Energy savings. A utility must use unit energy savings values and standard protocols approved by the regional technical forum, unless a unit energy savings value or standard protocol is:
(a) Based on generally accepted methods, impact evaluation data, or other reliable and relevant data that includes verified savings levels; and
(b) Presented to its advisory group for review. The commission retains discretion to determine an appropriate value or protocol.
(6) High efficiency cogeneration. A utility may count as conservation savings a portion of the electricity output of a high efficiency cogeneration facility in its service territory that is owned by a retail electric customer and used by that customer to meet its heat and electricity needs. Heat and electricity output provided to anyone other than the facility owner is not available for consideration in determining conservation savings. High efficiency cogeneration savings must be certified by a professional engineer licensed by the Washington department of licensing.
(7) Applicable sectors. A utility must offer a mix of conservation programs to ensure it is serving each customer sector, including programs targeted to the low-income subset of residential customers.
(8) Cost-effectiveness. A utility's conservation portfolio must pass a cost-effectiveness test consistent with that used in the Northwest Conservation and Electric Power Plan. A utility must evaluate conservation using cost-effectiveness tests consistent with those used by the Northwest Power and Conservation Council, and as required by the commission, except as provided by subsection (10) of this section.
(9) Utility incentives.
A utility may propose to the commission positive incentives designed to stimulate the utility to exceed its biennial conservation target as identified in RCW 19.285.060
(4). Any proposed utility incentive must be included in the utility's biennial conservation plan.
(10) Low-income conservation.
(a) A utility ((may))must fully fund low-income conservation measures that are determined by the implementing agency to be cost-effective consistent with the Weatherization Manual maintained by the department or when it is cost-effective to do so using utility-specific avoided costs. Measures identified through the priority list in the Weatherization Manual are considered cost-effective. In addition, when alternate funding sources are unavailable, a utility ((may))must fully fund repairs, administrative costs, and health and safety improvements associated with cost-effective low-income conservation measures.
(b) The utility's biennial conservation plan must include low-income conservation programs and mechanisms identified pursuant to RCW 19.405.120. To the extent practicable, a utility must prioritize energy assistance to low-income households with a higher energy burden.
(c) A utility ((may))must exclude low-income conservation from portfolio-level cost-effectiveness calculations. A utility must account for the costs and benefits, including nonenergy impacts, which accrue over the life of each conservation measure.
(((c)))(d) A utility must count savings from low-income conservation toward meeting its biennial conservation target. Savings may be those calculated consistent with the procedures in the Weatherization Manual.

The number of renewable energy credits that the utility may acquire from an industrial facility for the utility's target compliance may not be greater than the utility's renewable portfolio standard percentage times the industrial facility load.
(c) A utility that owns a qualified biomass energy facility may not transfer or sell renewable energy credits associated with qualified biomass energy to another person, entity, or utility.
(9) Use of energy output marketed by Bonneville Power Administration. Beginning January 1, 2020, a qualifying utility may use eligible renewable resources as identified under RCW 19.285.030 (12)(g) and (h) to meet its compliance obligation under RCW 19.285.040(2). A qualifying utility may not transfer or sell eligible renewable resources obtained from the Bonneville Power Administration to another utility for compliance purposes under RCW 19.285.040. (10) Use of nonemitting electric generation. Beginning January 1, 2030, a qualifying utility is considered to be in compliance with an annual renewable energy target in RCW 19.285.040 (2)(a) if the utility meets one hundred percent of the utility's average annual retail electric load using any combination of electricity from: (a) Renewable resources and renewable energy credits as defined in RCW 19.285.030; and
(b) Nonemitting electric generation, as defined in WAC 480-109-060(23).
Nothing in subsection (10) of this section relieves the requirements of a qualifying utility to comply with the conservation targets established under RCW 19.285.040(1).
AMENDATORY SECTION(Amending WSR 15-07-043, filed 3/12/15, effective 4/12/15)
WAC 480-109-210Renewable portfolio standard reporting.
(1) Annual report. On or before every June 1st, each utility must file an annual renewable portfolio standard report with the commission and the department detailing the resources the utility has acquired or contracted to acquire to meet its renewable resource obligation for the target year.
(2) Annual report contents. The annual renewable portfolio standard report must include the utility's annual load for the prior two years, the total number of megawatt-hours from eligible renewable resources and/or renewable resource credits the utility needed to meet its annual renewable energy target by January 1st of the target year, the amount (in megawatt-hours) of each type of eligible renewable resource used, and the amount of renewable energy credits acquired. Additionally, the annual renewable portfolio standard report must include the following:
(a) Incremental cost calculation. To calculate its incremental cost, a utility must:
(i) Make a one-time calculation of incremental cost for each eligible resource at the time of acquisition or, for historic acquisitions, the best information available at the time of the acquisition:
(A) Eligible resource levelized cost. Determine the levelized cost of each eligible resource, including integration costs as determined by the utility's most recently completed renewable resource integration study, using the utility's commission-approved weighted average cost of capital at the time of the resource's acquisition as the discount rate;
(B) Eligible resource capacity value. Identify the capacity value of each eligible renewable resource as calculated in the utility's most recent integrated resource plan acknowledged by the commission;
(C) Noneligible resource selection. Select and document the lowest-reasonable-cost, noneligible resource available to the utility at the time of the eligible resource's acquisition for each corresponding eligible resource;
(D) Noneligible levelized energy cost. For each noneligible resource selected in (a)(i)(C) of this subsection, determine the cost of acquiring the same amount of energy as expected to be produced by the eligible resource, levelized over a time period equal to the facility life or contract length of the eligible resource and at the same discount rate used in (a)(i)(A) of this subsection;
(E) Noneligible levelized capacity cost. Calculate the levelized capital cost of obtaining an equivalent amount of capacity provided by the eligible resource, as determined in (a)(i)(B) of this subsection, from a noneligible resource. This cost must be levelized over a period equal to the facility life or contract length of the eligible resource and at the same discount rate used in (a)(i)(A) of this subsection. To make this calculation, a utility must use the lowest-cost, noneligible capacity resource identified in its most recent integrated resource plan acknowledged by the commission. However, if a utility determines that cost information in the integrated resource plan is no longer accurate, it may use cost information from another source, with documentation of the source and an explanation of why the source was used.
(F) Calculation. Determine the incremental cost of each eligible resource by subtracting the sum of the levelized costs of the noneligible resources calculated in (a)(i)(D) and (E) of this subsection from the levelized cost of the eligible resource determined in (a)(i)(A) of this subsection. The result of this calculation may be a negative number.
(G) Legacy resources. Any eligible resource that the utility acquired prior to March 31, 1999, is deemed to have an incremental cost of zero.
(ii) Annual calculation of revenue requirement ratio. To calculate its revenue requirement ratio, a utility must annually:
(A) Sum the incremental costs of all eligible resources used for target year compliance;
(B) Add the cost of any unbundled renewable energy credits purchased for target year compliance;
(C) Subtract the revenue from the sales of any renewable energy credits and energy from eligible facilities; and
(D) Divide the total obtained in (a)(ii)(A) through (C) of this subsection by the utility's annual revenue requirement, which means the revenue requirement that the commission established in the utility's most recent rate case, and multiply by one hundred.
(iii) Annual reporting. In addition to the revenue requirement ratio calculated in (a)(ii) of this subsection, the utility must:
(A) Report its total incremental cost as a dollar amount and in dollars per megawatt-hour of renewable energy generated by all eligible renewable resources in the calculation in (a)(i) of this subsection; and
(B) Multiply the dollars per megawatt-hour cost calculated in (a)(iii)(A) of this subsection by the number of megawatt-hours needed for target year compliance.
(b) Alternative compliance. State whether the utility is relying upon one of the alternative compliance mechanisms provided in WAC 480-109-220 instead of fully meeting its renewable resource target. A utility using an alternative compliance mechanism must use the incremental cost methodology described in this section and include sufficient data, documentation and other information in its report to demonstrate that it qualifies to use that alternative mechanism.
(c) Compliance plan. Describe the resources that the utility intends to use to meet the renewable resource requirements for the target year.
(d) Eligible resources. A list of each eligible renewable resource that serves Washington customers, for which a utility owns the certificates, with an installed capacity greater than twenty-five kilowatts. Resources with an installed capacity of less than twenty-five kilowatts may be reported in terms of aggregate capacity. The list must include:
(i) Each resource's WREGIS registration status ((and use of certificates, whether it be for annual target compliance, a voluntary renewable energy program as provided for in RCW 19.29A.090, or owned by the customer
(ii) Eligible resources being included in the report for the first time and documentation of their eligibility.
(e) Multistate allocations.
(i) If a utility serves retail customers in more than one state, the utility must allocate certificates consistent with the utility's most recent commission-approved interstate cost allocation methodology. The report must show how the utility applied the allocation methodology to arrive at the number of certificates allocated to Washington ratepayers.
(ii) After documenting the number of certificates allocated to Washington ratepayers, a utility may transfer certificates to or from Washington ratepayers. The report must document the compensation provided to each jurisdiction's ratepayers for such transfers.
(f) Sales. If a utility sold certificates, report the number of certificates that it sold, their WREGIS certificate numbers, their source, and the revenues obtained from the sales. For multistate utilities, these requirements only apply to certificates that were allocated to the utility's Washington service territory according to (e) of this subsection.
(3) Report review.
(a) Interested persons may file written comments regarding a utility's annual renewable portfolio standard report within thirty days of the utility's filing.
(b) Upon conclusion of the commission review of the utility's annual renewable portfolio standard report, the commission will issue a decision accepting or rejecting the calculation of the utility's renewable resource target; determining whether the utility has generated, acquired or arranged to acquire enough renewable energy credits or qualifying generation to comply with its renewable resource target; and determining the eligibility of new renewable resources pursuant to subsection (2)(d) of this section.
(c) If a utility revises its annual renewable portfolio standard report as a result of the commission review, the utility must submit the revised final annual renewable portfolio standard report to the department.
(4) Publication of reports.
All renewable portfolio standard reports required by chapter 19.285
RCW and this section since January 1, 2012, must be posted and maintained on the utility's website. Reports must be posted on the utility's website within thirty days of the commission order approving the report. A copy of any such report must be provided to any person upon request.
(5) Customer notification. Each utility must provide a summary of its annual renewable portfolio standard report to its customers by bill insert or other suitable method. This summary must be provided within ninety days of final action by the commission on the report.
(6) Final compliance report. Within two years following submission of its annual renewable portfolio standard report, a utility must submit, in the same docket, a final renewable portfolio standard compliance report ((that)).
(a) The report must list((s)):
(i) The certificates that it retired in WREGIS for the target year; and
(ii) The use of certificates, whether for annual target compliance, a voluntary renewable energy program as provided for in RCW 19.29A.090, or owned by the customer
(b) If a utility does not meet its annual target described in WAC 480-109-200, the commission will determine the amount in megawatt-hours by which the utility was deficient.
AMENDATORY SECTION(Amending WSR 15-19-032, filed 9/9/15, effective 10/10/15)
WAC 480-109-300Greenhouse gas content calculation and energy and emissions intensity metrics.
(1) A utility must report its greenhouse gas content calculation and metrics of energy and emissions intensity to the commission on or before June 1st of each year. The report must include annual values for each metric for the preceding ten calendar years. Each value reported must be based on the annual energy or emissions from all generating resources providing service to customers of that utility in Washington state, regardless of the location of the generating resources. When the metrics are calculated from generators that serve out-of-state and in-state customers, the annual energy and emissions outputs must be prorated to represent the proportion of the resource used by Washington customers.
(2) ((The energy and emissions intensity report))Each utility must perform its greenhouse gas content calculation in accordance with the rules enacted by the department of ecology.
(3) In addition to the greenhouse gas content calculation, the report shall include the following metrics:
(a) Average megawatt-hours per residential customer;
(b) Average megawatt-hours per commercial customer;
(c) Megawatt-hours per capita;
(d) Million ((short))metric tons of CO2e emissions; and
(e) Comparison of annual million ((short))metric tons of CO2e emissions to 1990 emissions.
))(4)Unknown generation sources.
For resources where the utility purchases energy from unknown generation sources, ((often called "spot market" purchases,
)) from which the emission rates are unknown, the utility ((shall report emission metrics using the average electric power CO2 emissions rate described as the net system mix (spot market) in the Washington state electric utility fuel mix disclosure reports compiled by the department pursuant to RCW 19.29A.080
))must use an emissions rate determined by the department of ecology. If the department of ecology has not adopted an emissions rate for unspecified electricity, a utility must apply an emissions rate of 0.437 metric tons of CO2 per megawatt-hour of electricity
. For the resources described in this subsection, a utility must show in the report required in subsection (1) of this section the following:
(a) ((Short))Metric tons of CO2e from unknown generation sources;
(b) Megawatt-hours delivered to its retail customers from unknown generation sources; and
(c) Percentage of total load represented by unknown generation sources.
(((4)))(5) The greenhouse gas content calculation and energy and emissions intensity report must include narrative text and graphics describing trends and an analysis of the likely causes of changes, or lack of changes, in the metrics.
