FISCAL IMPACT No fiscal impact. 5. RECOMMENDATION There is no recommendation. Michael D. Holley, General Manager 6 Analysis Methodology The analysis methodology used in this Plan is that provided by KEMA Inc. through its contract with NCPA. The objective of that project was to provide the Northern California Power Agency (NCPA), the Southern California Public Power Authority (SCPPA) and all of their combined members with a consistent set of values for estimating energy and peak load reduction as a result of Public Benefits programs. KEMA was directed to capitalize on existing information and summarize it in a way that would be more accessible to NCPA/SCPPA members. Because many of the existing documents are complex and highly detailed, the project team significantly condensed the available detail into concise and more accessible measure summaries. The study team created measure summaries for all of the measures on the project list. The primary resources were the Database for Energy Efficient Resources (DEER) database and PG&E's workpapers. A goal of this report was to leverage existing results and summarize them in a simplified manner that was more accessible to NCPA and SCPPA members. The DEER database is a tool that was jointly developed by the California Public Utilities Commission (CPUC) and the California Energy Commission with support and input from the Investor- Owned Utilities and other interested stakeholders. The DEER database includes detailed information on a select group of energy efficiency measures. The results include the gross impacts, incremental cost, and the equipment's useful life. The calculations that are behind the DEER results include engineering calculations, building simulations, measurement studies and surveys, econometric regressions, or a combination of the approaches depending on the specific measure. The objectives and focus of the DEER data is to serve as a centralized source of information for planning and forecasting issues for the energy efficiency programs that are provided to customers across the state. The DEER database takes the form of an interactive web site where users can query the data for specific measure information. The database is located on the CPUC website and is available at: http://eega.cpuc.ca.gov/deer/. The PG&E workpapers are the documents that PG&E has prepared to document all of their measure savings calculations related to all of their existing programs. The workpapers for PG&E alone are a substantive set of measure details that PG&E uses to defend energy savings assumptions. The papers are filed on a regular basis with the CPUC. This NCPA/SCPPA measure summary product used the 2005 version of the PG&E workpapers. The workpapers typically include measures not in the DEER database or that are new to their programs. Given that such a great amount of effort had been expended in the development of an authoritative resource that would produce results that would be on a consistent analytical basis with nearly all other utilities in California, the Committee opted to use this methodology to analyze potential efficiency measures in the TDPUD service territory. The KEMA report including the PG&E workpapers are available as Appendix B to this report. 7 TDPUD's Unique Load Profile Electricity The hourly overall use of power in any jurisdiction can give important clues about the use of power by end users, and can help reveal what usage patterns may lead to the loads faced by the utility. The hourly loads can also provide insight into patterns of use that cause costs to be incurred by the utility to serve those loads. By examining closely the load profile in the District, the Committee was able to discern the usage patterns and amounts of electricity use that are prevalent at various points in time. The Committee used this information to evaluate some of the various potential strategies for reducing energy use (e.g. since there is little variation in summer loads, indicating that there are very few residential air conditioners, most residential air conditioning measures were dropped from consideration). Historical records of energy use were examined for insights into energy use and its timing. Mr. Steven Hollabaugh, TDPUD's Assistant General Manager for Electricity Supply, made a presentation to the Committee on August 16, 2007, showing the nuances of the District's load profile. He also provided hourly loads for the district from 2006 for the Committee to analyze. Mr. Hollabaugh also presented information about the District's power supply contracts. Since the District does not own generation, but rather is a wholesale customer of a variety of generators, these power supply contracts will reveal what the cost of power is at any given point in time. Power contracts may charge for energy (MWh), capacity (MW), fixed charges, or have other charge mechanisms. Of importance to the work of the Committee is to use the power cost information to determine what the savings would be for a given strategy or set of strategies. For example, if capacity cost is determined by the highest level of demand during the year, then an energy conservation measure that reduces power consumption during the peak would have capacity cost savings throughout the year, in addition to its energy savings. Conversely, another energy efficiency measure may have significant savings for a certain device, but if that device is not typically in use during the peak, or if it doesn't account for many kilowatt-hours of energy consumption throughout the year, then it won't have much effect on the District's load profile or power cost. The structure of the contracts will have a great effect on the measures that ultimately will be recommended. TDPUD Annual Loads Truckee's load profile is driven for the most part by the recreational and tourism aspects of the community. High daily peaks are driven for the most part by increased occupancy of second homes, vacation rentals and lodging. The TDPUD system is a winter peaking utility with the winter peak being about 37 MW. The system peak occurs between Christmas and New Years due to the influx of people into the community. The summer peak of about 23 MW is centered around the July 4th holiday period and is also tied to increased town occupancy. Daily peaks (shown in Figure 7-1) are higher from Thanksgiving through the end of the ski season than they are during the rest of the year. The annual system peak occurs on the Saturday between Christmas and New Years with a great degree of regularity. This peak is followed closely by the President's Day holiday weekend. Peaks on other winter weekends are also noticeably higher than winter weekdays. The daily peaks taper off from the end of the ski season to Memorial Day. There is then an increase through the July 4th summer peak and then the load levels out through Labor Day.

Winter load profiles peak in the evening due to the incidence of electric heating and extra holiday lighting loads. Weekend afternoon and evening loads are higher than weekday loads because of increased occupancy of second homes and area lodging facilities. Winter weekday and weekend loads are shown in Figure 7-2.

Weekday loads are constant at about 20 MW from about 11 am to 6 pm with a slight dip in the early evening and an increase later in the day. The increase in late evening loads could be caused by the operation of some of the major summer loads on the TDPUD system operating in the late evening (waste water treatment, water system pumping, etc). Summer weekend loads are slightly lower in the day but the late evening peaks are similar to weekday loads. Figure 7-3 presents summer weekday and weekend load profiles.

CaISO operates the power grid for about 80 percent of California. SPP serves Reno and the northern Nevada region and NCPA is the total of municipal loads for cities in the NCPA interconnected power pooling agreement. Recent legislation regarding conservation programs and GHG reductions assume that all utilities in California have similar loads. That is to say there is an assumption that the daily peaks of utilities follow the same pattern as the CaISO. For TDPUD this is not the case. For most if not all other utilities in California the peak is in the summer months when it is hot and not in the winter as in TDPUD. For comparison purposes Figure 7-4 shows a comparison of daily peaks as a percentage of annual peak for both TDPUD and the California ISO. Percentages were used eliminate the difference in size of each entity. While the TDPUD peak is about 36 MW the peak for the ISO is over 50,000 MW. It is easy to see that the ISO peaks are more variable in the summer (caused by air conditioning loads) while the TDPUD peaks are relatively constant and the TDPUD loads vary more in the winter when the ISO loads are relatively constant. It can also be seen that in contrast to the TDPUD daily peaks which are higher during weekend and holiday periods that the CaISO daily peaks are significantly lower on weekends and holidays.

While the majority of Sierra Pacific load is centered in the Reno and northern Nevada area and not subject to California regulations, it is interesting to look at because it is the closest utility region to TDPUD. Unlike the CaISO the SPP region shows an increase in loads from Thanksgiving through the end of the ski season caused by a fraction of the service area which serves the Lake Tahoe Basin. There is smaller variation in weekend and holiday differences because the Tahoe Basin is a small fraction of the overall SPP control area. Summer loads for SPP are driven by temperature related air conditioning loads of Reno and the surrounding areas.

What is notable in this comparison other than the similar summer pattern is that the NCPA peaks appear to greatly decrease during weekend periods while the TDPUD peaks increase during the weekend periods in the winter (especially in winter and holiday periods) and are relatively constant in the summer with the exception of increases in holiday periods.

The TDPUD loads exhibit higher loads in the early morning and late in the evening caused by the incidence of electric heat in the TDPUD area. The CaISO loads have smaller increases in these time periods caused by a lower incidence of electric heat.

This is where there is a marked difference in daily shape between TDPUD and other utilities. The summer TDPUD loads are relatively flat throughout the daylight hours while the CaISO loads show an increase over the afternoon caused by air conditioning load.

The consequence of this unique load profile and the TDPUD's power contract structure is that the most economically efficient programs in Truckee are those that reduce kilowatt hours overall not those that shave the highest peaks. The Committee therefore focused its attention on conservation or efficiency measures that produce the most kWh savings, regardless of the time of day or time of year they are used. The Committee also avoided measures that are primarily aimed at air conditioning efficiency improvement. Water Figure 7-9 depicts the water use by month for the most recent 3 years. The baseload between November and April represents the indoor uses, such as personal hygiene, cooking, and washing, which would not be expected to change based on weather or time of year. The large midyear increase peaking in July and August can be attributed to landscape watering. The amount of water used in this peak period has grown to about 2/3 as much as all other uses combined. Also, the load has grown dramatically in the spring months, showing a 66% increase during May and June over the 2-year period.

Advances have been recently made in landscape watering control technology, such as systems that communicate with irrigation controllers to indicate the expected plant evapotranspiration rate for the day, and controllers that regulate the frequency and duration of watering cycles to maximize soil absorption and all but eliminate runoff. Efficiency improvements for the indoor uses are also well established and effective, so the Committee examined those technologies as well. Water and Power Conservation Plan 9 Conservation Measures Considered Electricity The DEER database presents a comprehensive list of some 5,500 efficiency measures that could potentially be used by any utility district in the development of its conservation/efficiency programs. Committee members combed through the list and eliminated measures related to residential air conditioning, because with such a small number of homes with a/c, the measure simply would not work in Truckee. Similarly measures that would affect commercial equipment that is not present were eliminated. The following lists give the set of measures finally selected by the Committee for recommendation. Table 9-1 lists the measures that apply to residential facilities, and Table 9-2 lists the measures for the Commercial Sector.

The TDPUD watershed is protected by federal law and isolated morphologically. The only way to lose water from this system is through runoff into the river, or through evaporation. The aquifer appears to be sufficient to provide for the needs of the District for the foreseeable future. Delivery of this water to the District's customer-owners is another matter. The costs of pumping the water over the significant elevations present in the service territory amount to 8% of the District's electrical load, the largest single electricity customer. The infrastructure to deliver the water presents a large fixed cost. The energy used in pumping creates a significant "carbon footprint" due to the predominance of coal-fired power plants in the District's supply portfolio. All of these issues offer good reasons to conserve water, even though the commodity itself is plentiful. Table 9-3 shows the water conservation measures presented by the staff, and recommended by the Committee, for adoption.

III.Gerald moves to accept the minutes as is, John seconds the motion and a vote is taken. Minutes pass with a voice vote. IV.No members of the public in attendance. Gerald discusses Truckee Day scheduled for June 7m Coordinator of the event, Beth Ingalls, has changed the name to Truckee Green and Clean Day to include more of a "green message". If a group like the TDPUD cleans up an area, then a booth area is assigned to that group to use during the luncheon. A booth was suggested to promote the agenda of the committee. The booth could be staffed by committee members that hand out and provide information on the conservation programs currently being offered by the TDPUD. Historically they have had a few booths, this year they are looking to increase the number of booths. No commerce is invited it is only open to educational and informative booths. Eric suggested that perhaps the TDPUD would be a better choice to have a booth to increase the outreach and community education of all the TDPUD programs. A conservation suggestion bucket was suggested with the best idea winning a prize. Suzie said she might be able to get some merchandise from Patagonia. The idea box includes the public in the process, this would increase the awareness for the need to recycle or conserve and perhaps generate some new fresh ideas. This is an opportunity to raise awareness with an already environmentally active group of Truckee residents. Announcing the contest and prizes at the sign in areas (where bags and T-shirts are handed out) might increase attendance at the picnic. Eric also brought up the need to include TV's in the appliance recycling program. People watch an average 7 hours of TV a day. Plasma and tube TVs consume way more energy than an LCD. Joanna suggested the event timing would be ideal for promoting low-water landscaping and other water conservation programs. V.Doug recapped the Board meeting held on February 20th. Pres. Taylor had requested to see the macro schedule of the Conservation Committee at the prior meeting, so that was provided. Doug handed out the draft outline of the Conservation Plan, and asked for comments. He also asked how the Board felt about the Committee possibly volunteering for the District in other roles outside of the Committee. Lastly, he asked the Board's opinions on a suggestion to release draft parts of the Committee's Water and Energy Conservation Plan in discreet pieces over a period of time, instead of all at once as a finished product. Possible volunteering options presented by the Board were working as docents on the Solar Energy Tour and working the TDPUD booth on Memorial Day weekend during the Home Show. It was stated that all volunteering should go through the GM. There were concerns that the volunteering would displace TDPUD workers, open the TDPUD to liability, and possibly create confusion within the District operations. Some Directors were approving of the outline as presented but the Board warned that the Committee needed to keep the document simple and short. With respect to the Committee releasing draft chapters as they are produced, the Board would like to see some chapters from the document in April, even if it is in rough draft form. Once the document is finished it will be open Conservation Committee: Minutes: March 4, 2008 1 for public comment. If the material is sent to any board member it is out and in public, so the Committee needs to be thoughtful about what is presented to the Board in April. The Board was also concerned that too much jargon would be used, and requested that the Committee keep in mind that it needed to be consumable and understood by the general public. For the next board meeting, it was requested that Doug connect the document outline with the 5 points with which the Committee was charged. A discussion followed on possibly trimming the scope of the document or breaking into more than one document. In reality, the Executive Summary will be the primary section that people will read, so it is crucial that the Executive Summary is as tight and concise as possible. Incorporating ideas generated from the public would also be beneficial, in the Board's point of view. Which portion of the document should be focused on and completed first? A discussion followed about breaking the document into `parts.' Material that is supportive should be pushed to the back. Our primary goal is to provide the information for the District to be able to move forward in a conservation-conscious manner with the information we have provided in the Plan. Michael called Doug before the board meeting, as a courtesy, to discuss the possibility of reframing "Alan's" job description prior to hiring for the vacant position. This was a heads up because the change might affect the committee in some ways because the new position would be Conservation and Information Officer for the District. This is a good move because it releases the position from duties outside the scope and elevates Conservation within the structure of the District. Michael gave the Committee the opportunity to add some decor and exhibits to the lobby of the TDPUD to promote conservation and renewable energy. This is an opportunity to get the conservation message out and set the tone as soon as you walk into the District offices. Tons of ideas were thrown around, creating a program for school kids to create the material used, a kiosk to calculate carbon output, exhibits of various energy saving equipment, etc. Possibly the Outreach subcommittee should spearhead the project? VI.The Committee members were directed to the section of the document that covers Recommendations. All of the recommendations were reviewed with changes made as necessary for clarity. The Board recently approved a voluntary green tag program for customers. Building green power generation is intimidating so this is a start. There is a lot of confusion with the difference between green tags, white tags, renewable energy credits (REC's) and the authenticity of the tags. The industry is moving towards more regulation and becoming more transparent. In the future, there needs to be a central organization like the stock exchange to regulate the industry. Until then, purchasing green tags is still an environmental good choice. Local renewable energy would be the best way to go in terms of the security for our power supply and public awareness. There is only one way energy comes into town, from the east, so building a local power supply would create energy security. It would also give people the ability to point at the source of their local clean power. Purchasing green tags does not send the renewable energy to the specific customer -- it creates an offset for the damage created from using non-renewable energy. There are 2 issues; the carbon footprint and public relations. Both could use some support in the local community. Solar panels on the roof of the TDPUD would be the equivalent of walking the conservation talk. Every town building should be a showcase of conservation. These enhancements cannot come out of the 2.85% Conservation budget based on the wording of the legislation. The outreach group created the bullet point for creating recommendations for other agencies in town, sanitary district, the airport and school district. The sewer district and sewer authority (T- Conservation Committee: Minutes: March 4, 2008 2 TSA and TSD) are creating a lot of natural gas; this could be collected and used to power the facilities for T-TSA and TSD. Currently, it is used to provide some heating and flared off. This could be cleaned up and used. The agencies would still need to supplement with natural gas. Joanna also wants to see the 2.85% collected separately on the bill, so it would have its own line item. The money would then be easy to track, increasing the transparency and accountability. It might motivate customers to recoup the -3%. You could include ideas on how to save 10% with the separation of the fee on the bills. This would remove all the questions on how much, where and what is happening with the conservation money. It might also paint a bull's eye on the fee. Questions followed about accounting questions within the District. No one seemed to know what kind of check and balances were in place. Is there an annual, monthly or quarterly financial audit? "TURN" is a watchdog group over investor-owned utilities to monitor utility activities. Should the committee suggest an "ombudsman"- similar to internal affairs? The cost and size of the District does not support. It is clear that to ensure the longevity of the programs recommended by the Committee, financial controls need to be in place to protect the conservation budget. Perhaps the Committee could meet annually to discuss the current state of affairs of the District, as a Citizen Accounting Committee. An annual accounting of conservation programs should be looked as a PR opportunity for the District to publicize all the money that was spent for public benefit. VII. "Conservation Measures Considered" and TDPUD's Unique Load Profile were suggested as the first chapters to review with the board. This connects very directly to the 5 points. VIII. Meeting was adjourned 9:10pm Conservation Committee: Minutes: March 4, 2008 3
