[Statutory Authority: RCW 19.285.080. WSR 15-07-002, § 194-37-060, filed 3/6/15, effective 4/6/15; WSR 14-04-015, § 194-37-060, filed 1/24/14, effective 2/24/14. Statutory Authority: RCW 19.285.080(2). WSR 08-07-079, § 194-37-060, filed 3/18/08, effective 4/18/08.]



194-37-070
Development of conservation potential and biennial conservation targets.

(1) Ten-year potential. By January 1st of each even-numbered year, each utility shall identify its achievable cost-effective conservation potential for the upcoming ten years.
(2) Biennial target. By January 1st of each even-numbered year, each utility shall establish and make public a biennial conservation target. The utility's biennial target shall be no less than its pro rata share of the ten-year potential identified pursuant to subsection (1) of this section.
(3) Each utility must document the methodologies and inputs used in the development of its ten-year potential and biennial target and must document that its ten-year potential and biennial target are consistent with the requirements of RCW 19.285.040(1). Each utility must apply methodologies consistent with the most recently published regional power plan using inputs that reasonably reflect the specific characteristics of the utility and its customers and the general characteristics of the Pacific Northwest power system.
(4) Each utility must establish its ten-year potential and biennial target by action of the utility's governing board, after public notice and opportunity for public comment.
(5) The methodologies used by the NWPCC in its most recently published regional power plan are summarized in this subsection.
(a) Technical potential. Determine the amount of conservation that is technically feasible, considering measures and the number of these measures that could physically be installed or implemented, without regard to achievability or cost.
(b) Achievable technical potential. Determine the amount of the conservation technical potential that is available within the planning period, considering barriers to market penetration and the rate at which savings could be acquired.
(c) Economic achievable potential. Establish the economic achievable potential, which is the conservation potential that is cost-effective, reliable, and feasible, by comparing the total resource cost of conservation measures to the cost of other resources available to meet expected demand for electricity and capacity. A utility may use either of the following approaches to identify economic achievable potential:
(i) Integrated portfolio approach. A utility may analyze, as a part of its integrated resource plan, the cost-effective potential of conservation resources over a range of potential future outcomes for unknown variables, such as future demand, costs, and resource availability. Economic achievable potential will be based on resource plan that achieves a long-run least-cost and least-risk electric power system considering all power system costs and quantifiable nonenergy costs and benefits.
(ii) Benefit-cost ratio approach. A utility may establish economic achievable potential as those conservation measures or programs that pass a total resource cost test, in which the ratio of total benefits to total costs is one or greater. The benefit-cost calculation must use inputs that incorporate the cost of risks that would otherwise be reflected in an integrated portfolio approach.
(d) Total resource cost. In determining economic achievable potential as provided in (c) of this subsection, perform a life-cycle cost analysis of measures or programs to determine the net levelized cost, as described in this subsection:
(i) Conduct a total resource cost analysis that assesses all costs and all benefits of conservation measures regardless of who pays the costs or receives the benefits;
(ii) Include the incremental savings and incremental costs of measures and replacement measures where resources or measures have different measure lifetimes;
(iii) Calculate the value of the energy saved based on when it is saved. In performing this calculation, use time differentiated avoided costs to conduct the analysis that determines the financial value of energy saved through conservation;
(iv) Include the increase or decrease in annual or periodic operations and maintenance costs due to conservation measures;
(v) Include avoided energy costs equal to a forecast of regional market prices, which represents the cost of the next increment of available and reliable power supply available to the utility for the life of the energy efficiency measures to which it is compared;
(vi) Include deferred capacity expansion benefits for transmission and distribution systems;
(vii) Include deferred generation benefits consistent with the contribution to system peak capacity of the conservation measure;
(viii) Include the social cost of carbon emissions from avoided nonconservation resources;
(ix) Include a risk mitigation credit to reflect the additional value of conservation, not otherwise accounted for in other inputs, in reducing risk associated with costs of avoided nonconservation resources;
(x) Include all nonenergy impacts that a resource or measure may provide that can be quantified and monetized;
(xi) Include an estimate of program administrative costs;
(xii) Include the cost of financing measures using the capital costs of the entity that is expected to pay for the measure;
(xiii) Discount future costs and benefits at a discount rate equal to the discount rate used by the utility in evaluating nonconservation resources; and
(xiv) Include a ten percent bonus for the energy and capacity benefits of conservation measures as defined in 16 U.S.C. § 839a of the Pacific Northwest Electric Power Planning and Conservation Act.

WSR 08-07-079, § 194-37-070, filed 3/18/08, effective 4/18/08.]



194-37-080
Documentation of conservation savings.

(1) Each utility must document its acquisition of conservation savings relative to its biennial target.
(2) Each utility must record conservation savings as the total first-year electricity savings in megawatt-hours or kilowatt-hours.
(3)(a) Each utility must maintain and apply measurement and verification protocols to determine the amount of energy savings resulting from conservation measures and to verify the acquisition or installation of the conservation measures being recorded or claimed.
(b) A utility may comply with this requirement using the measurement and verification protocols adopted by the RTF or by BPA in its energy efficiency implementation manual. If a utility uses other measurement and verification protocols, the measurement and verification protocols must be consistent with recognized industry practices, and the utility must document the methodologies, assumptions, and factual inputs used in its measurement and verification of energy savings.
(4) A utility may count the conservation savings from a conservation measure toward its biennial target if the measure, or a project or program consisting of more than one measure, meets the following criteria:
(a) The utility has established that the measure, or a program or project consisting of more than one measure, was cost-effective;
(b) The utility has documented that the measure was installed within its retail service area during the biennial period, or in the case of programs described in subsection (5) of this section, that the savings were attributed to the utility using a reasonable and consistent method;
(c) The utility used a reasonable and consistent method of assigning conservation savings to biennial periods such as, by the date the conservation measure was installed, by the date an incentive was paid to a customer, or by the date the conservation measure was reported to an external funding agency such as BPA; and
(d) The utility applied a reasonable and consistent policy of incorporating changes in unit energy savings values subsequent to the adoption of a biennial conservation target. Such a policy may either count savings using the unit energy savings values in effect at the time the biennial target is established or update all unit energy savings values as they are changed by the entity responsible for establishing the values.
(5) Subject to the requirements of subsection (4) of this section, each utility may count toward its biennial conservation target the proportionate share of savings resulting in its service territory from the implementation of regional or multistate conservation programs, market transformation programs, appliance standards, building energy codes, and nonprogrammatic savings including, but not limited to, the Northwest Energy Efficiency Alliance and BPA.
(6) A utility must not count as conservation a reduction in electricity consumption due to curtailment of a customer's process or service, such as the shutdown of a manufacturing facility. A change in the operating practices of a customer that reduces electricity consumption without reducing the level of output or other benefits of electricity consumption is not curtailment.
(7) A utility that does not acquire conservation savings during a biennial period sufficient to meet its biennial conservation target may document its level of effort at conservation acquisition. The documentation should include:
(a) A description of the utility's marketing programs, education programs, custom project proposals, monetary incentives, financing offers, and other efforts during the biennial period to motivate customers to install conservation measures;
(b) A detailed report of the utility's budget and actual expenditures for the activities in (a) of this subsection;
(c) An identification of all conservation measures, programs, or projects for which the utility offered to pay customers an incentive in an amount equal to the utility's full avoided cost over the lifetime of measures; and
(d) An identification of all conservation measures that were included in the biennial target and became unavailable to the utility due to the shutdown or curtailment of operations of a retail customer.

194-37-085
Documentation of conservation savings from high-efficiency cogeneration.

(1) A utility may count as conservation savings a portion of the electricity output of a high-efficiency cogeneration facility that commences operation in its service territory.
(2) The high-efficiency cogeneration facility must be 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 may not be considered in determining conservation savings.
(3) The useful thermal energy output of the cogeneration facility must be no less than thirty-three percent of the total energy output of the cogeneration facility under normal operating conditions.
(4) The reduction in customer load due to high-efficiency cogeneration must be determined by multiplying the annual electricity output of the cogeneration facility by a fraction equal to one minus the ratio of:
(a) The heat rate (in British thermal units per megawatt hour) of the cogeneration facility; and
(b) The heat rate (in British thermal units per megawatt hour) of a combined cycle natural gas-fired combustion turbine. The heat rate of the cogeneration facility must be based on the additional fuel requirements attributable to electricity production and excluding the fuel that would be required to produce all other useful energy outputs of the project without cogeneration. The heat rate of the combustion turbine must be based on a facility using best commercial available technology on a new and clean basis.
(5) The utility's documentation of a cogeneration facility's compliance with subsections (3) and (4) of this section must be certified by a registered professional engineer licensed by the Washington department of licensing.

(a) The hydroelectric generation project is owned by a qualifying utility and is located in the Pacific Northwest;
(b) The hydropower efficiency improvement was completed after March 31, 1999; and
(c) The additional generation does not result in new water diversions or impoundments.
(2) If the amount of electricity generated as a result of the hydropower efficiency improvement is directly measurable, the utility must use the measured output of the hydropower efficiency improvement as documentation of the amount of additional generation.
(3)(a) If the amount of electricity generated as a result of the hydropower efficiency improvements is not directly measurable, the utility must document the amount of electricity generated as a result of the hydropower efficiency improvement using an engineering analysis comparing the output in megawatt-hours of the hydroelectric generation project with the efficiency improvement to the output in megawatt-hours of the hydroelectric generation project without the efficiency improvement. Multiple efficiency improvements to a single hydroelectric generation project may be combined for purposes of the engineering analysis.
(b) The engineering analysis required by (a) of this subsection must be performed using an engineering model of the hydroelectric generation project that quantifies the relationship of stream flows, reservoir elevation, and other relevant factors to the electric output of the generating facility. The engineering model must accurately reflect the physical characteristics and operating requirements of the hydroelectric generation project during the target year and must accurately estimate the electric generation of the hydroelectric generation project without and with the hydropower efficiency improvement.
(c) A utility using the engineering analysis method to determine incremental generation must adopt and consistently apply in each target year one of the following methods:
(i) Method one - Actual incremental generation. A utility using this method must prepare an analysis using actual stream flows and the engineering model described in (b) of this subsection during each target year to determine incremental generation in the target year. A utility using this method must perform an updated calculation each year to determine the incremental generation amount for that target year.
(ii) Method two - Percentage generation.
(A) A utility using method two must prepare an analysis establishing the expected amount of incremental generation based on stream flows available to the hydroelectric generation project, adjusted for any known and measurable changes to stream flows due to environmental regulations or other factors, during a historical study period.
(B) The historical study period used in method two must be reasonably representative of the stream flows that would have been available to the hydroelectric project over the period of time for which stream flow records are readily available. A historical study period meets the requirements of this subsection if it includes the most recent readily available stream flow records and consists of a consecutive record of stream flow records at least five years in length.
(C) The amount of incremental generation using method two is calculated by multiplying the actual generation in megawatt-hours in the target year by a percentage amount equal to the difference between the calculated average generation over the historical study period with the hydropower efficiency improvement and the calculated average generation over the historical study period without the hydropower efficiency improvement, divided by the calculated average generation over the historical study period without the hydropower efficiency improvement.
(iii) Method three - Fixed amount of generation.
(A) A utility using method three must prepare an analysis establishing the expected amount of incremental generation based on stream flows available to the hydroelectric generation project, adjusted for any known and measurable changes to stream flows due to environmental regulations or other factors during a historical study period.
(B) The historical study period used in method three must be reasonably representative of the stream flows that would have been available to the hydroelectric project over the period of time for which stream flow records are readily available. A historical study period meets the requirements of this subsection if it includes the most recent readily available stream flow records and consists of a consecutive record of stream flow records at least ten years in length.
(C) The amount of incremental generation using method three is calculated as an amount in megawatt-hours equal to the difference between the calculated average generation over the historical study period with the hydropower efficiency improvement and the calculated average generation over the historical study period without the hydropower efficiency improvement. The amount must be adjusted in each target year for any reduction in availability of the hydroelectric generation project's generating capacity during the target year that is not accounted for in the analysis used to calculate the incremental generation amount.
(4) The requirements of this section are in addition to the documentation requirements specified in WAC 194-37-120(1).

Documentation of financial cost cap—Current information and timeline.

By January 1 of the first target year that a utility fulfills its renewable energy requirements under RCW 19.285.050, the utility shall select one of the following methodologies for documenting the incremental cost of all eligible renewable resources acquired thereafter by that utility:
(1) Annual update methodology. In each year that a utility fulfills its renewable energy requirements by complying with the cost cap identified in RCW 19.285.050 it must document its calculations no later than January 1 of the target year. The utility will use the most current information available to the utility within twelve months prior to the initial documentation of the cost cap pursuant to WAC 194-37-170 through 194-37-190. The utility will update this documentation in its June 1 report submitted pursuant to RCW 19.285.070. These annual updates of costs, based on the most current information available, apply to both the eligible renewable resource and the substitute resource.
(2) Permanent one-time methodology. For each new investment in an eligible renewable resource, a utility shall perform a one-time calculation of the levelized incremental cost pursuant to WAC 194-37-170 through 194-37-190. The levelized incremental cost shall be a single annual value expressed in real, constant-year dollars. The levelized incremental cost for each eligible renewable resource project or purchase, calculated through this one-time analysis in the year of acquisition, shall be allowed to inflate utilizing the Producer Price Index over the life of the eligible renewable resource after the initial calculation. The utility will include a determination of incremental cost for each new investment in an eligible renewable resource and inflation-adjusted incremental costs for previous eligible renewable resource investments in its June 1 report submitted pursuant to RCW 19.285.070, beginning in the year the utility complies with the cost cap identified in RCW 19.285.050.

Documentation for financial path—Levelization of costs.

(1) Each utility must document its calculation of the levelized annual incremental cost of eligible renewable resources. Utilities are encouraged, but not obligated, to use the following methodology:
Step 1: Calculate the net present value of the cost of the utility's eligible renewable resource and substitute resource over an equivalent contract length or facility life.
Step 2: Calculate equal nominal values over the appropriate contract length or facility life that have a net present value equal to those calculated in Step 1, using the same discount rate.
Step 3: Calculate the annual difference between the levelized delivered cost for the eligible renewable resource and the substitute resource to determine the levelized incremental cost of the eligible renewable resource.
A utility that uses the annual update methodology must document the basis for any change to the levelization methodology used in a prior June 1 report to levelize the costs of an eligible renewable resource and its associated substitute resource.
(2) Regardless of the methodology chosen to levelize costs, utilities must document the basis for their chosen method for levelizing costs.
(3) Utilities must document the basis for the discount rate used in its levelized cost calculations.
(4) Utilities must document how the discount rate used to perform the levelized cost calculations is consistent with the inflationary assumptions incorporated into the delivered cost projections for the eligible renewable resource and substitute resource.
(5) Utilities must document how the method and assumptions used to levelize delivered costs for the eligible renewable resource are consistent with those used to levelize the delivered cost of the associated substitute resource.

Documentation of financial path—Delivered cost.

(1) The delivered cost of a resource includes all direct and indirect costs associated with that resource being delivered to the distribution system of a utility over the contract length or facility life of the delivered resource. Direct and indirect costs may include operating and capital expenses related to the delivered resource.
(2) Using the Uniform System of Accounts of the Federal Energy Regulatory Commission (FERC) as an illustration, the reported resource costs are expected to generally fall within, but not necessarily be limited to, the following cost accounts:
Operating Expenses
 
Accounts 500-557:
Production Expense
Account 565:
Wholesale Wheeling Expense
Accounts 920-935:
Administrative and General Expense
Account 408.1:
Taxes Other than Federal Income Taxes
Capital Expenses
 
Accounts 403-407:
Depreciation and Amortization Expense
Accounts 427-431:
Interest-Related Expenses
(3) A utility may include actual costs in order to equitably compare the costs of eligible renewable resources and substitute resources. This may include the actual costs of transmission, firming, shaping, integration, and project specific development costs.
(4) Utilities are encouraged to use the FERC system of accounts to document the delivered cost of resources. Regardless of the accounting convention used, utilities must document the delivered cost estimates for eligible renewable resources and their associated substitute resources in a manner consistent with generally accepted accounting standards.

194-37-190
Documentation of financial path—Substitute resource and resource equivalence.

(1) In support of its annual filings to the department under RCW 19.285.070, utilities must document the type, availability, and cost of the reasonably available substitute resource used to calculate the incremental cost of an eligible renewable resource.
(a) In documenting the incremental cost under RCW 19.285.050 (1)(b), a utility is encouraged to identify substitute resources using its integrated resource planning process, if one is available. If a utility elects to choose a substitute resource from a different source other than its most recently published integrated resource plan, it must document the basis for this decision. Documentation of the cost of a substitute resource may include, but is not limited to, formal offers for the sale of electricity, or published cost projections from reputable third-party sources.
(b) In its selection of a substitute resource, the utility shall develop documentation demonstrating that the substitute resource satisfies the requirements set forth in RCW 19.285.050. The requirements are:
(i) Equivalence between the eligible renewable resource and the substitute resource by demonstrating the equivalence in the amount of energy produced by each resource;
(ii) Equivalence between the eligible renewable resource and the substitute resource by demonstrating the same contract length or facility life of each resource;
(iii) The substitute resource is reasonably available to the utility; and
(iv) The substitute resource does not qualify as an eligible renewable resource.
(c) Only supply-side substitute resources shall be used by utilities in the calculation of the incremental cost of eligible renewable resources.
(d) When the renewable requirements under RCW 19.285.040(2) result in a utility having resources in excess of its load, the utility may use that excess resource as the substitute resource if the substitute resource requirements of (b) of this subsection are otherwise satisfied. The utility will document the resale revenues, net of transaction costs, received through the sale of excess resources or the purchase price for the sale of the excess facility sold as a result of the requirement to acquire eligible renewable resources. A utility that uses a value other than the documented resale revenue in the determination of the levelized delivered cost of the substitute resource, such as a forecast of projected market prices, must provide documentation to support this alternative approach.
(e) A utility may use foregone power purchases from BPA, plus any billing credit obtained for reducing its purchases from BPA, as the basis for the cost of the substitute resource if:
(i) The substitute resource requirements of (b) of this subsection are otherwise satisfied;
(ii) It is entitled under its BPA power sales contract to have the BPA meet its net power requirements for the expected life of an eligible renewable resource or eligible renewable resource purchase; and
(iii) As a result of meeting the renewable requirements under RCW 19.285.040(2), it foregoes part of its BPA entitlement in order to obtain that eligible renewable resource.
(2) For an eligible renewable resource acquired prior to the passage of chapter 19.285 RCW, November 7, 2006, a utility must support the selection of the related substitute resource used in the determination of the incremental cost under RCW 19.285.050 with documentation that was available at the time of the utility's decision to acquire the eligible renewable resource. If no such documentation is available, the incremental cost of an eligible renewable resource acquired prior to the passage of chapter 19.285 RCW will be assumed equal to zero.

Financial documentation path using renewable energy credits.

A utility may elect to invest in RECs to meet any portion of, or the entirety of, each annual renewable resource target in RCW 19.285.040(2) or 19.285.050(1). If the cost of the RECs and the incremental cost of acquired renewable resources, as documented according to WAC 194-37-150 through 194-37-190, for any one year meets or exceeds four percent of the utility's annual revenue requirement, the utility shall document that the utility achieved the four percent cost cap alternative compliance path in RCW 19.285.050(1). The documentation must include copies of its WREGIS RECs, copies of purchase contracts, and its annual revenue requirement.
