Resources Management (CRM). To bring our Tacoma Power takes energy conservation very customers this most seriously. As communities grow, their utility is affordable of all power resources, these leaders, usually faced with needing to acquire additional analysts, engineers, product and market experts, power generation like solar, wind or natural office assistants and administrative assistants gas generation. In recent years, Tacoma Power work as a close knit team to help customers has worked very hard to avoid these expensive understand their energy options and our programs. acquisitions, which invariably require utilities to raise their rates. To help postpone or reduce future rate increases and maintain a clean power portfolio of almost entirely renewable hydropower, we have focused on conserving energy. This, together with retailers and mom and pop shops, to engineering firms, wholesalers and other regional program serving customers wishing to reduce their energy contributed to Tacoma Power customers enjoying some of the lowest electricity rates in the country. use and make the energy of the future cleaner and more secure. In additional to thanking CRM, we owe special thanks to individuals in some key sister This plan is written with many audiences in mind. It is a report to Senior Management and our Public Utility Board, a detailed program implementation departments such as Energy Resource Planning and Evaluation, Community and Media Services, Market Development and Government Relations. They roadmap for our staff and a tool for developing have been incredibly helpful and true partners in our 2017-2018 budget. For government officials assisting us with planning and evaluation, market and staff, it is an explanatory document outlining how Tacoma Power intends to meet its obligations under the law. For other utilities and program research, advertising, public relations and public policy objectives. This is not a complete list of all who contribute to our success, both inside and implementers, it may serve as a benchmarking tool. We have tried to be cognizant of these various audiences in our writing, but realize you may still have questions after reading it. If so, we are happy to further discuss our programs with you. outside the City of Tacoma, and our gratitude extends to others too numerous to name who help us save our customers energy and money. I hope you enjoy reading our Conservation Plan. If you read earlier Conservation Plans, you will note that this plan has been condensed from previous plans. This was intended to make the Conservation variety of readers. from equipment dealers and installers, to big box implementerss — to partner in a common vision of our low cost hydro resources, has significantly Plan more readable and accessible to a wider They also work with many trade allies — ranging I would be happy for feedback on any part of this plan you might care to offer. Steve Bicker Assistant Power Section Manager / CRM Senior Manager [email protected] TACOMA POWER 2016/17 Conservation Plan 1 differences between 2014-15 and 2016-17 Integrated Resource Plan Changes to Assumptions and Baselines The 2013 Integrated Resource Plan (IRP) indicated that annual During the 2014-2015 biennium, the Bonneville Power supply would not be adequate to meet customer loads beginning Administration (BPA) made two major changes to savings in 2025 under critical water conditions. It also showed significant assumptions used by Tacoma Power. These changes impact gaps between supply and demand in the fall and winter quarters what measures we offer, the incentives we pay to customers and beginning in the early 2020s under low water conditions. Since program design. that analysis, Tacoma Power has significantly reduced the load forecast to reflect the observed reduction in retail load growth. This reduction, coupled with other changes, led to the 2015 IRP’s conclusion that Tacoma Power will not need to acquire new resources beyond energy conservation during the next 20 years. Weatherization The Regional Technical Forum (RTF) reduced unit energy savings estimates for all residential weatherization measures. The change was based on an updated Simplified Energy Enthalpy Model (SEEM) with data from the Residential Building Stock Assessment Increased Target (RBSA) and results from an Energy Trust of Oregon study. Tacoma Power’s 2016-2025 Conservation Potential Assessment Energy savings were reduced for all residential weatherization (CPA) identified more economically achievable energy savings measures. However, window and attic insulation had the largest than the 2014-2023 CPA, resulting in a 15% larger target. This reduction. BPA adopted the lower energy savings in October 2015. increase occurred despite a lower price forecast and fewer cost effective residential measures. The increase is driven by lower cost LED lighting within all sectors and new data from a recent commercial building stock assessment. This chart illustrates how the target has increased and how some of the conservation potential has shifted from residential to commercial. 2 TACOMA POWER 2016/17 Conservation Plan The reduced energy savings, combined with a lower wholesale power forecast, caused several popular weatherization measures to fail our cost effective test. As a result, Tacoma Power is removing the following measures from our Residential Weatherization, Low-Income and Multifamily programs in 2016: •Single-pane windows (5+ unit multifamily buildings only) •Double-pane windows (all building types) •Attic R19-R49 insulation (all building types) Commercial Lighting In July 2012, the Energy Policy Act (EPACT) and Energy Independence and Security Act (EISA) prohibited the manufacture and import of certain inefficient light bulbs. After reviewing regional sales data, BPA determined EPACT and EISA had transformed the commercial lighting market. BPA has revised calculation methods to assume future retrofits will be made using EPACT- and EISA-complying products. This is counter to our observation that many inefficient products continue to reside in commercial buildings within our service territory. However, to comply with BPA reporting requirements, we have adopted the new commercial lighting baseline change, which results in lower reportable energy savings and lower incentives paid to our customers. Community Solar and Net Metering Tacoma Power is implementing a new community solar program. Under this program, customers may purchase a unit of Tacoma Power’s new solar installation. Tacoma Power will leverage our experience in project management and programs delivery to ensure the new program is successful. The project is expected to begin service by June 2016. Community Solar and Net Metering are supported by CRM staff and budget. (Cost of non-resource acquisition programs such as community solar are not included Trade Allies Starting in 2015, CRM reinvigorated efforts to enlist third-party companies and contractors who design, sell or install highefficiency equipment or offer solutions that qualify for our incentive programs. By partnering with these companies, known as “trade allies,” Tacoma Power will reach a larger portion of our customers than staff could alone. In 2015, CRM allocated a staff member to managing Tacoma Power’s network of trade allies. We are making the following improvements to make our programs more trade-ally friendly: • Modifying our program rules and messaging to be consistent across all programs • Using the latest technology to exchange information with trade allies • Develop, track and share performance indicators with trade allies • Develop and implement joint marketing in the economic analysis.) TACOMA POWER 2016/17 Conservation Plan 3 conservation at Tacoma Power Business Case for Conservation While the IRP determines conservation’s role in Tacoma The business case for energy conservation is compelling. Assessment (CPA) determines the potential for cost-effective and Providing incentives to use energy more efficiently is the cheapest, cleanest way to fulfill our obligation to serve our customers. Power’s resource portfolio, the ten-year Conservation Potential achievable conservation acquisitions within our service territory. In 2015, Applied Energy Group (AEG) conducted a CPA for Tacoma Power. The CPA examined more than 7,000 unique conservation Load Resource Balance Conservation plays a key role in meeting our future energy needs by deferring acquisition of costly new resources. Conservation is Tacoma Power’s first resource — it’s available today and costs measures to determine our economic and achievable potential. AEG’s methodology is consistent with the Northwest Power and Conservation Council (NWPCC) and fulfills our obligations under the Energy Independence Act (RCW 19.285). less than other resource alternatives*. The chart below contrasts The CPA identified 46.8 aMW of achievable cost-effective conservation resources cost with alternatives from Tacoma conservation in our service territory during 2016-2025.

The 2016-2017 Conservation Plan has a program for conservation is the only resource we need to acquire for 20 years. everybody in our service territory. Customers can save between 5 to 30 percent of their electricity costs by participating in our energy conservation programs. * Conservation resource costs are calculated using Acquisition Cost Analysis (ACA). The ACA looks at Tacoma Power’s cost to acquire energy savings, including all costs incurred by the utility (incentives, staff overhead and marketing). ACA does not include costs assumed by the customer. These values may differ from estimated TRC values found in the CPA and IRP. 4 TACOMA POWER 2016/17 Conservation Plan It is well known within the industry that energy efficiency Because failing to meet the EIA target is not an option, Tacoma programs improve customer satisfaction. J.D. Power reports that Power establishes program goals and budgets to achieve more simply offering energy conservation programs raises customer than our target. Planned energy savings beyond our 9.4 aMW satisfaction scores by about 100 points on a thousand point target for 2016-2017 is a risk reduction strategy. scale. Tacoma Public Utilities has begun building new internal market research capabilities and will do more tailored and Conservation Budget Risk Mitigation specific research to better understand how Tacoma Power The 2016-2017 Conservation Plan is aligned with the state’s customers prefer to learn about and use CRM’s conservation regulatory EIA biennium. However, Tacoma Power’s 2015-2016 programs. budget biennium is based on City of Tacoma budget cycles. This strategy supports an accurate planning process, but is Environmental Stewardship somewhat constrained by our approved 2015-2016 budget. In addition to load resource balance and customer satisfaction, References to 2017 expenditures and budget allocations are Tacoma Power feels a strong obligation to make the best estimates. The actual budget will require Public Utility Board use of our hydro resources. Energy conserved through our approval of Tacoma Power’s 2017-2018 Capital and O&M budget. conservation programs allows Tacoma Power to meet future energy demand from our current sources of clean, renewable hydropower. Legislative Mandate In 2006 Washington State voters voiced their desire for utilities Currently CRM has an approved 2015-2016 budget of $32,640,000. Additionally, $1,880,000 is budgeted for workgroups outside of CRM: Community and Media Services (marketing) and Energy Resource Planning and Evaluation. Tacoma Power’s total conservation budget is $34,520,000. to provide more energy conservation by passing Initiative 937, Conservation incentives paid to Tacoma Power customers are the Washington Energy Independence Act (EIA) (RCW 19.285). the largest expense category, accounting for approximately 62% While primarily a renewable portfolio standard, the EIA requires of planned expenses. Program labor, marketing and contracted mid- and large-sized utilities of 25,000 customers or more implementation account for approximately 15% of planned to acquire all “cost-effective and achievable” conservation. expenses. The remaining 23% is shared between overhead, This has been interpreted as a pro-rata share of the 10-year research/evaluation costs and marketing labor. economic achievable potential identified by our CPA. Policy for Conservation Target and Budget Setting Target Setting and Reporting The EIA makes two key points governing how we set conservation targets. 1. Targets set under RCW 19.285 apply to the compliance biennium and not to individual years. 2. RCW 19.285 / WAC 194.37 do not require individual programs or sectors to account for any particular part of the overall target. Conservation programs are sensitive to overspending: • Large commercial and industrial projects can have lead times up to several years, with timetables that change rapidly. • It is difficult to predict which efficient products will be popular and what new technology will be available in the market. • Economic drivers beyond our control may drive participation above historical levels. To manage these risks, Tacoma Power has developed a conservation budget reservation system to ensure funds are reserved and not promised to more than one customer. The While Tacoma Power’s Conservation Plan must use program- system tracks program funding allocations to determine how specific assumptions, including unit energy savings and much has been spent, how much reserved and how much is numbers of units, there is no requirement for these forecast to be spent. Projects under contract and expected assumptions to carry though to implementation. We regard to be completed within the budget biennium will have funds our portfolio mix as a tool to manage risk. This is important, reserved to ensure incentives are available and avoid the as individual programs may over- or under-perform due to the potential for over commitment. unpredictable nature of the energy efficiency market. TACOMA POWER 2016/17 Conservation Plan 5 Sensitivity Analysis Tacoma Power uses a Monte Carlo approach, which examines multiple program outcomes across the conservation portfolio to ensure planned acquisitions and budgets are adequate to meet regulatory and load/resource needs. Managers and supervisors predict program performance using past experience, current participation levels and market knowledge. This knowledge is modeled using probability distributions to test the impact on budget and energy savings acquisitions for a variety of program outcomes. The table below illustrates the probability of outcomes given program variability for 10,000 combinations of program performance factors. Analysis shows our portfolio met or exceeded targets in more than 90% of model runs. Based on this analysis, absent a radical policy change or market shift, CRM is confident its portfolio will meet Tacoma Power’s acquisition needs. The next table illustrates that Tacoma Power needs to increase CRM’s capital budget to meet the 9.4 aMW target. Based on the analysis, the current capital budget of $21,100,000 would meet our needs in only 57% of the model runs. A budget above $22,100,000 would be more suitable given the larger target identified by the IRP and CPA. 6 TACOMA POWER 2016/17 Conservation Plan Finally the chart below shows which programs in our portfolio have the most significant performance variability. NEEA energy savings has the most variability, but use of conservative assumptions minimizes risk. In these scenarios, NEEA is an upside risk. Large C/I programs have the most downside risk due to the unpredictable nature of large projects and long lead times. Portfolio Design Principles CRM uses three key principles to design the conservation portfolio: 1. Conservation is IRP driven 2. Conservation programs must satisfy customers 3. Conservation spending must be equitably distributed Development of the portfolio requires careful balancing of these sometimes competing portfolio design principles. • Total Resource Cost Test (TRC) – The EIA requires that utilities use a TRC test to determine if a conservation measure is cost effective. Tacoma Power believes the TRC test best ensures that rate funds are used properly for energy efficiency, avoiding subsidy of technologies that are not in the best of interest of the region. The TRC compares the present value of total benefits to the present value of total costs paid by Tacoma Power and program participants. All conservation programs offered by Tacoma Power must pass the TRC test. • Utility Cost Test (UCT) – The UCT projects the financial Conservation is justified in Tacoma Power’s IRP Tacoma Power’s IRP helps make the business case for the conservation planning process. The “Smooth Sailing” scenario from the IRP provides the price curve to analyze resources in the CPA. These price forecasts favor measures that reduce load during heavy load hours, typically during the winter when Tacoma Power’s customers use electricity for heating. Finally, the IRP sets the EIA conservation target approved by the Public Utility Board and submitted to the Washington State Department of Commerce. In addition, we use several cost effective models to test programs within the conservation portfolio. Each of these models reflects a different economic perspective on energy efficiency. impacts of conservation programs on Tacoma Power, specifically how a program’s cost impacts electric revenues. The UCT compares the costs of offering a program, including utility-paid program costs and lost retail revenues, to the benefit of avoided power supply costs. Tacoma Power works to maximize energy savings from programs with a low UCT, but must also balance equity concerns, as these programs are primarily focused on large industrial customers. • Participant Test (PT) – The PT ensures program participants are better off participating in our energy conservation programs. The PT uses a simple comparison of costs to benefits to measure the attractiveness of a program to a customer. Tacoma Power uses the PT to determine if customers would likely participate in a given program. TACOMA POWER 2016/17 Conservation Plan 7 Conservation must be marketed In the marketplace, energy conservation investments such as Conservation must be distributed equitably among customer groups home insulation compete for consumer dollars against other Conservation programs at Tacoma Power are funded through home investments such as granite countertops. Tacoma Power power rates. Because all customers pay rates, it is important all must market programs to capture customers’ attention, motivate customers have access to our energy conservation programs. them to take action and ensure their satisfaction with the While most low-cost energy savings come from large commercial experience, the products and the energy savings. Residential and industrial customers, it is important to provide programs marketing that promotes home comfort as well as reduced for residential customers who have uncomfortable homes with energy costs are effective to motivate customers to participate. high energy bills but may be unable to afford home efficiency Commercial/industrial programs marketing is effective when improvements. promoting reduced overhead and maintenance costs, which help make companies more profitable.

This is true even if the measure delivers slightly lower energy savings than an alternative product that saves more but annoys the consumer.

These resources provide customers with over five years. Future programs will pay incentives and assistance on how to save energy, assess opportunities and create an energy acquire energy savings over a two-year period. management team. Three program variants are currently offered: • High Performance Energy Management (HPEM): Targets large industrial customers seeking ways to save energy through system-wide operations and maintenance improvements. A structured network of participants is established to share best practices and learn in a group setting. The program includes monthly group meetings facilitated by HPEM coaches where participants learn from peer experience. Incentives are based on operations and maintenance energy savings below a baseline model developed for each facility. • Track & Tune: Targets operations and maintenance improvements achievable through a “tune-up” process requiring little or no capital investment. Track & Tune can be applied to an entire plant or targeted sub-systems within an industrial facility. Good candidates use either more than 1 million kWh per year in a sub-system or more than 4 million kWh per year plant-wide. Incentives are based on operations and maintenance energy savings below a baseline model. • Energy Project Manager: Provides co-funding to large industrial customers who hire an “energy champion” to identify energy savings opportunities. The energy champion must manage capital projects that result in at least 1,000,000 kWh of energy savings. Incentives are paid based on kWh saved for implemented energy conservation measures. New challenges for 2016-2017 BPA is considering expanding their SEM program to include large commercial customers. In the event that BPA develops a large commercial SEM offering, Tacoma Power may choose to expand our program and engage this customer class. In absence of a BPA offering, Tacoma Power may pilot a large commercial SEM offerin How Customers participate BPA establishes program criteria through the Energy Smart Industrial initiative (ESI).

TACOMA POWER 2016/17 Conservation Plan 17 Residential programs * Budget numbers estimated using 2017 assumptions. Actual budget will be 18 TACOMA POWER 2016/17 Conservation Plan approved through Tacoma Power’s biennial budget process. Tacoma Power offers a variety of energy conservation programs that help our residential customers save money and keep their homes comfortable. Our residential programs are organized by market channel, such as weatherization installers, allowing Tacoma Power to leverage residential trade allies to help promote program participation. Two sector-specific programs, low income and multifamily, focus on helping customers who pay for conservation but lack the means to participate due to their financial or housing situation. Metric Residential Projected energy savings 2.64 aMW Acquisition cost $40/MWh TRC benefit/cost ratio 1.1 2017-18 capital budget* $11,242,000 TACOMA POWER 2016/17 Conservation Plan 19 Residential program Retail $4,245,000 planned Capital and O&M expenditures $33 / MWh planned levelized costs 14% 1.3 TRC B/C ratio 1.32 aMW Percentage of planned 2016-17 portfolio energy savings energy savings “If customers are on the fence about LEDs and the cost before the incentive, the incentives make it work!” Program overview The Retail Program leverages retailers’ experience selling products to the mass market and conservation incentives to encourage customers to choose efficient products. The program relies on retailer and manufacturer participation to stock, promote, sell and report the sale of efficient products. Products include: Chris • Lighting (LED, CFL and light fixtures) Home Depot sales staff • Showerheads • Appliances (clothes washers, refrigerators, freezers) How Customers participate Residential customers visit participating retailers within our service territory and purchase products at the point of sale. CRM’s point of purchase material (POP) directs customers to incentivized products. Retailers discount products at the register, making the experience seamless for customers – no rebate forms to fill out and mail in. Tacoma Power contracts with a third-party expert, CLEAResult, to deliver the program within our service area. CLEAResult provides field support to ensure POP material is properly displayed, enters into promotion agreement with retailers and manufacturers on behalf of Tacoma Power, pays incentives to retailers and manufacturers and reports units sold to CRM. Additionally, CLEAResult assists CRM by advising on product incentives, introducing new technologies, identifying participating locations, ensuring products are on the shelf, maintaining POP and training sales staff. 20 Incentives Tacoma Power pays incentives relative to product price and the amount of reportable energy savings. Instant rebate incentives, ranging from $1.00 for inexpensive CFLs up to $15.00 for expensive showerheads, help create price parity between inefficient and efficient products. New challenges for 2016-2017 LEDs have matured in the residential market place, gaining superior customer acceptance to CFLs. CRM staff expects LEDs to achieve price parity with CFLs in the near future. As a result, the program will shift its residential lighting focus from CFL to LED lighting products in the 2016-2017 biennium. CRM will explore opportunities to acquire energy savings by participating in BPA’s Simple Steps program for appliances, thermostats and possibly smart power strips. CRM currently participates in this program and claims allocated energy savings for lighting sales in non-CRM retail locations. The program may expand to offer incentives directly to retailers for the sale of appliances and electronics at top efficiency tiers. Energy savings will be allocated to utilities using BPA’s Retail Sales Allocation Methodology. CRM’s participation is contingent on a program design that meets our needs and passes Tacoma Power’s standard cost effective tests.

Tacoma Power also offers qualifying customers zero interest seven-year loans to help cover the cost of installation and make major investments in home energy conservation more affordable. New challenges for 2016-2017 Tacoma Power’s Weatherization Program will be significantly revised for 2016-2017 due to energy saving reductions made by the Regional Technical Forum (RTF) and adopted by BPA. The reduction made several popular weatherization measures no longer cost effective, requiring the removal of attic R19-R49 insulation and double-pane windows from our program. Additionally, heat pump heated homes will no longer be eligible. Tacoma Power plans to keep participation similar to historic levels through increased incentives and direct marketing. 22 TACOMA POWER 2016/17 Conservation Plan Residential program Distribution $202,000 planned Capital and O&M expenditures >1% $45 / MWh planned levelized costs 1.0 TRC B/C ratio Percentage of planned 2016-17 portfolio energy savings 0.06 aMW energy savings Program overview The distribution program provides low-cost energy saving products to customers at no charge.

Transmission and Distribution Energy Savings The following activities are not budgeted within CRM, nor are Tacoma Power’s Transmission and Distribution (T&D) staff have energy savings included in the conservation plan. been cooperating with BPA’s Energy Smart Utility Efficiency (ESUE) program since 2011. Efforts have centered on the study Momentum Savings Momentum Savings quantifies energy efficiency that occurs outside of utility and NEEA programs. These savings occur because utility energy efficiency programs have reshaped the marketplace. Over time, this momentum of change leads to energy savings that are much broader than what utilities originally providing incentives for. BPA is currently championing Momentum Savings. It is unclear if regulators will accept Momentum Savings towards EIA targets without third-party verification. As a result, Tacoma Power is not relying on Momentum Savings to meet EIA targets in the 2016-2017 Conservation Plan. However, if these energy savings prove reliable, meet Tacoma Power’s cost effective tests and benefit our customers, CRM intends to report Momentum Savings as part of our EIA accomplishments. 28 TACOMA POWER 2016/17 Conservation Plan and implementation of distribution system improvements and Voltage Optimization (VO). VO saves energy by more tightly regulating voltage to the most efficient operating point for end use consumption devices. VO improvements can include changes such as voltage regulators, phase rebalancing or capacitors. During 2016-2017 T&D plans to implement VO at 4-6 additional substations with an anticipated energy savings of 0.20-0.40 aMW. While not budgeted or managed within CRM, CRM will report these energy savings as part of our EIA accomplishments. COMMUNITY SOLAR and Net Metering Net Metering The Renewable Energy System Cost Recovery Act expires on June Through the Renewable Energy System Cost Recovery Act (RCW 30, 2020. Total compensation for participants is $1.12 kWh through 82.16.12 / WAC 458-20-273), Tacoma Power offers customers with the end of the Act. At this time, Tacoma Power will estimate solar qualifying distributed generation (DG) systems retail credit for production for years 2021-2036 and pay participating customers a electricity generated and delivered to the grid and access to lump sum buyout for the value of solar energy produced. Washington State’s renewable energy production incentives for electricity generated through these systems. Tacoma Power recoups renewable production incentive payments made to customers through reduced utility taxes. Current incentives are: • Avoided retail purchase: $0.07/kWh • Renewable production credit: $0.12/kWh – $0.54/kWh Total compensation ranges between $0.19/kWh and $0.61/kWh. Community Solar Similar to Net Metering, Washington State pays an incentive for each kilowatt hour generated by community solar projects. To meet customer expressed interest and to give our customers access to these incentives, Tacoma Interested customers will be served on a first come, first served basis. The number of solar units will be limited per household to allow as many customers as possible to participate. Community Solar and Net Metering Challenges The state legislature has been evaluating the Renewable Energy System Cost Recovery Act and entertaining potential changes to the Act during the past several sessions. Most of these potential changes would alter incentive amounts beyond 2020. However, while most of these bills grandfather current Community Solar and Net Metering participation, there is a risk the legislature could change incentive levels between now and 2020.

Current incentives are: • State Production Credit – $1.08 kWh • Value of Solar Energy – $0.04 kWh TACOMA POWER 2016/17 Conservation Plan 29 MEASUREMENT AND VERIFICATION The following Measurement and Verification Plan was submitted • Energy Savings = final, verified annual kWh savings and approved by BPA on November 10, 2015. • Baseline Energy Use = annual kWh consumption for the existing condition, typically based on trend data or Purpose and Objectives This Measurement and Verification Plan (M&V Plan) defines project-specific measurement and verification methods for determining energy savings resulting from Tacoma Power’s commercial and industrial conservation incentive projects. M&V activities help ensure that conservation projects achieve their estimated savings and also maintain their savings over time. The M&V Plan provides direction in verifying and documenting energy savings that will be claimed under Initiative 937. An M&V Plan for individual projects is required by the Bonneville Power Administration (BPA) for participation in BPA programs. Specific M&V activities that require metering are identified in calculations • Post-Installation Energy Use = verified, annual kWh energy consumption for the proposed condition, after ECMs are installed and M&V activities are completed Adjustments may be made to properly account for any differences in conditions between the Baseline Energy Use and the PostInstallation Energy Use. M&V Plans will be written for all ECM projects or programs. The above equation may be modified to reflect specific situations. For example, the equation may be modified to depict more accurate energy savings from extrapolation of monitoring data to annual savings values. the BPA M&V Protocol Selection Guide. In general, direct energy metering applies to projects with annual energy savings of tacoma Power Conservation Programs 200,000 kWh or greater. For energy savings projects that meet set Energy Conservation Measures (ECMs) and conservation incentive criteria, BPA’s M&V protocols allow engineering calculations with projects for commercial and industrial customers are categorized verification without specific energy metering activities. under specific Tacoma Power conservation programs. The Tacoma Power projects that have annual savings of 200,000 kWh or more (designated as “Large Projects”) will generally have metering performed to verify energy savings. Tacoma Power projects that have annual savings of less than 200,000 kWh (designated as “Small Projects”) will generally have detailed savings calculations without metering. However, when exact current programs being offered (not including the BPA-designed programs) are: 1. Bright Rebates Lighting Program 2. New Construction Program 3. Custom Retrofit Program energy savings for these projects is less certain, Tacoma Power 4. Strategic Energy Management may supplement energy calculations with metering. 5. EnergySmart Grocer Program For the purposes of this M&V Plan, “energy savings” are defined 6. Equipment Rebate Program by the following equation: 7. Multifamily Retrofit Program Energy Savings = (Baseline Energy Use) – (Post-Installation Energy Use) ± Adjustments 30 TACOMA POWER 2016/17 Conservation Plan Large conservation projects with savings of 200,000 kWh or more will generally occur only under the first three programs (Bright Rebates Lighting, New Construction and Custom Retrofit). These guidelines may be modified as needed for specific projects. • Constant load, constant operating hours Guidelines for additional ECMs will also be developed as needed. • Constant load, variable operating hours Tacoma Power may develop additional commercial and industrial programs. These programs will produce conservation projects that will require M&V activities; requirements for these projects will be developed when the programs are nearing roll-out. o Variable hours with a fixed pattern o Variable hours without a fixed pattern (e.g., weather dependent) • Variable load, variable operating hours M&V Methods A recognized industry standard for M&V is the International Performance Measurement and Verification Protocol (IPMVP) publication (Volume 1 – Concepts and Options for Determining o Variable hours or load with a fixed pattern o Variable hours or load without a fixed pattern (e.g., weather-dependent) Energy and Water Savings) prepared by the Efficiency Valuation Organization. The IPMVP has four options for consideration: • Option A – Retrofit Isolation: Key Parameter Measurement • Option B – Retrofit Isolation: All Parameter Measurement • Option C – Whole Facility • Option D – Calibrated Simulation Tacoma Power will also consider the M&V approach based on these categories. Uncertainty or Risk of Achieved Savings An ECM with which the facility staff is familiar may require less M&V rigor than ECMs that are less well known. However, an ECM BPA has also published specific M&V protocols for its programs, with higher risks or level of savings uncertainty may require more including protocols for equipment and end-use metering, M&V rigor. modeling and new construction. Some of these publications are written more for general guidance. Tacoma Power will follow the general guidance provided in the latest IPMVP and in the BPA M&V documents whenever possible and practical. The selection of a specific M&V approach will be based primarily on the following: 1. ECM project savings and incentive amounts 2. ECM or ECM project complexity 3. Uncertainty or risk of achieved ECM savings ECM Project Incentive Amounts As a general guideline, the M&V effort will be scaled to the value of the project (in terms of annual kWh savings and incentive amount) so that the value of the information provided by the M&V activity is appropriate to the value of the project itself. An approximate guideline for M&V costs is 1% - 3% of the project’s conservation incentive amount. ECM or ECM project Complexity The complexity of isolating the savings is a critical factor in General Energy Analysis Procedures Tacoma Power has operated commercial and industrial energy conservation programs for more than 20 years and has substantial experience in analyzing ECMs. Tacoma Power uses (or requires) standard and industry-accepted engineering calculations and analysis procedures for estimating ECM energy savings. All savings assumptions are well-documented. A basic outline of the steps used in analyzing ECM projects and their energy savings is presented below: STEP 1: DEFINE ECM BASELINE CONDITIONS Baseline conditions shall be well documented. A detailed energy assessment of existing conditions is required. In general, baselines will be derived using from one to two years of documented energy consumption history. For baseline conditions that do not exist physically (such as in new construction projects or when existing energy-using equipment is non-functional or at the end of its useful life), the most current Washington State Energy Code and standard industry shall be used to determine baseline conditions. deciding on an M&V method. Projects can be put in the following Metering for M&V will be conducted as required to further categories (in order of increasing complexity): document the baseline conditions. In general, a baseline annual energy consumption value will be stated in the M&V Plan. TACOMA POWER 2016/17 Conservation Plan 31 STEP 2: PERFORM ENERGY ANALYSIS OF ECMS in the customer incentive contract. Depending on the ECM, An energy analysis of each measure will be performed using specific operational and maintenance requirements are standard engineering calculations and procedures. This analysis included. For large retrofit and new construction projects, formal produces both Baseline Energy Use and Post-Installation Energy commissioning may be included as a requirement of funding. At Use quantities (in annual kWh) that are used to determine annual a minimum, the Washington State Energy Code’s commissioning energy savings. For Bright Rebate projects, Tacoma Power uses requirements will be part of the ECM installation requirements. the BPA Lighting Calculator to analyze energy savings. For Custom Retrofit and New Construction projects, spreadsheet calculator tools or whole building energy simulation models may be used depending on project complexity. In order to provide the customer with complete ECM economic information (as well as to examine ECMs for cost-effectiveness), the analysis will also include estimates of kW demand savings and operational savings. Extrapolation to annual savings values Metering Equipment and Protocols Metering Equipment Tacoma Power maintains a variety of metering tools that will be used for M&V activities. The following is a partial list of equipment. will be used. Annual hours of use from which extrapolation is 1. Foot-candle light meters based will be documented in each specific project M&V Plan. 2. Lighting occupancy sensor/loggers 3. Motor data loggers STEP 3: IMPLEMENT PROJECT The ECMs are installed and M&V procedures are completed. STEP 4: PERFORM POST-INSTALLATION ECM INSPECTION An inspection of the completed project is conducted. The M&V results are reviewed and the ECM installation is examined to ensure that ECMs are functioning as specified and that energy savings are being realized. 4. AC current loggers 5. Power loggers All metering equipment will be properly maintained and checked periodically to ensure accuracy. Light meters and other equipment will be regularly calibrated to known standards (such as the National Institute of Standards and Technology). Power meters will be tested periodically and compared to reference power analyzers by Tacoma Power’s Meter Shop. Tacoma Power’s standard power metered are the Dent ElitePro recorders. Tacoma Power meter shop personnel have tested these meters and found STEP 5: PERFORM ADJUSTMENTS them to meet suggested accuracy levels. If post-installation conditions are found to be different than baseline conditions, the baseline and/or the post-installation may need to be adjusted in order to accurately account for changes in energy savings. The final energy savings would be revised based on this adjustment. The following are common reasons for adjusting the energy savings in ECM projects: 1. Changes in weather or occupancy data 2. Changes in hours of operation or tenant improvements 3. Changes in the actual function of the facility or process 4. For industrial plants, changes in production levels Quality Assurance Procedures Tacoma Power ensures that all ECMs are installed properly and function as specified before projects are approved for conservation incentives. In addition to M&V procedures, completed projects must meet detailed specifications outlined 32 TACOMA POWER 2016/17 Conservation Plan Protocols The following are general protocols for metering: 1. Raw data: all raw metering data will be compiled into standard data formats compatible with various common spreadsheet formats. 2. Variables measured: variables selected for measurement shall be based on the guidelines presented in this M&V Plan. 3. Metering duration: the time period for both baseline and post-installation metering shall be selected based on the guidelines presented in this M&V Plan. In addition, the BPA M&V End Use Metering Protocol provides detailed guidance and examples of methods appropriate for various categories of equipment and end uses. For projects over 200,000 kWh, a minimum of fourteen continuous days will be required, unless supplemental metering data is Environmental Design accredited professional (LEED AP) and available. Building Energy Simulation Analyst (BESA). When needed, the 4. Sampling size: the number of metering points shall be based on the guidelines presented in this M&V Plan. The sampling size will also vary based on the individual project characteristics. Budget and Resource Requirements Meter Shop provides support for conducting detailed power logging. M&V activities may also be performed by outside consultants and engineers. In some instances, post-installation metering may be performed by the customer (an example is variable monitoring from the customer’s building energy management system). For activities performed by outside personnel, all Tacoma Power M&V requirements must be met. Budget Tacoma Power has allocated funds for M&V activities as part of the total approved funding for each conservation program. Depending on the program, some M&V costs may be covered by the conservation incentive paid to the customer. These costs will generally be for post-installation M&V metering activities. For example, a large compressed air project may incur costs for postinstallation metering using flow measurement devices or other specialized equipment. These metering costs can be included as part of the ECM installation costs as long as they meet the M&V requirements. Factors affecting M&V costs are: 1. Verification of baseline and post-installation details 2. Sample sizes (number of data points) used for metering representative equipment 3. Confidence and precision levels specified for energy savings analyses 4. Duration and accuracy of metering activities 5. Availability of existing data collection systems 6. Type of metering used 7. Dependency on site personnel to assist with M&V efforts As previously mentioned, Tacoma Power uses the guideline that M&V costs typically range between 1% - 3% of the project’s conservation incentive amount. resource Requirements M&V activities may be performed by Tacoma Power’s Conservation Resources Management field staff or Tacoma Power’s Meter Shop. Currently, our Conservation Resources Management staff includes lighting experts and engineers experienced in assessing and analyzing energy savings for a variety of commercial and industrial ECMs. Furthermore, our staff currently possess a variety of relevant credentials including Lighting Certified (LC) Professional, Professional Engineer (PE), Certified Energy Manager (CEM), Leadership in Energy & TACOMA POWER 2016/17 Conservation Plan 33
