Holzmeister General Manager Truckee Donner Public Utility District P.O. Box 309 Truckee, California 96160-0309 Dear Mr. Holzmeister: Subject: Electric System Master Plan - Load Projections On October 22, 1991, the District engaged R. W. Beck to perform an Electric System Master Plan covering the next 30 years(1991-2020). Pursuant to our proposal,we have completed our first task of projecting District loads for the study period. The load projections are broken down into neighborhoods in order to understand the impacts on District substations. The load projections are coordinated with economic development scenarios postulated by others. As we know, one truth about projections are they are always wrong More importantly is the question. what is the impact of being wrong? To err on the high side would be conservative, since the District can always delay its program to conform to reality. To err on the low side would be risky, since the District would have to accelerate its program — a difficult accomplishment. I invite you to review the projections and present any comments you or your staff may have. Very truly yours, R. W. BECK AND ASSOCIATES Dean H. Park Principal Engineer DHP:jm (1415-06.DHP) Enclosure iottr X�I* ,A��,sG•(Eaha ti[n'E1n�e;,i'i'Imi "N ... ...................._. DRAFT ELECTRIC SYSTEM MASTER PLAN PROJECTED LOADS I. INTRODUCTION A. Authority On October 22, 1991, the Truckee Donner Public Utility District (District) engaged R. W. Beck and Associates to prepare an Electric System Master Plan (Plan). The purpose of this Plan is to provide the District with a plan of improvements to the electric system while meeting the requirements of AB 1600. The first step of the Plan is to project District loads. Loads are projected at five year intervals, except for 1991 to 1995, beginning in 1991 (base year) and ending in 2020. B. Methodological Approach The District's service area was divided into two parts: developable areas and excluded areas. Excluded areas are those areas held in the public domain; e.g., national and state forest lands, state parks and other public ownerships. The developable areas are those areas that are currently zoned in the Nevada County General Plan. The developable areas were further divided into nine neighborhoods: Downtown Gateway Olympic Heights/Martis Valley Estates (OH/MVE) Sierra Meadows/Ponderosa Palisades/Martiswood Estates (SM/PP/MWE) Prosser Areas/Coachland/Forest Service (Prosser) Donner Lake (DL) Tahoe Donner (TD) Airport, including the tentative Gooseneck Ranch Glenshire _1_ Glenshire was excluded from further consideration, since only a small portion of Glenshire is within the District's sphere of influence, and the current proposal would detach that area from the District. Sierra Pacific Power Company already serves the area. However, adjacent portions of Placer County, I.e., Martiswood Estates and Gooseneck Ranch, which are now outside the District's sphere of influence,were included because the current proposal would annex these areas into the District. The attached map, Figure , shows the boundaries of these neighborhoods. For each neighborhood, a 1991 baseline customer count and electricity sales per customer was established. Using the development scenarios contained in relevant planning reports, projections were made as to the number of customers to be added at five-year intervals. The electricity sales in those same intervals was then calculated. Both the District-wide annual energy usage per average commercial account and the annual energy usage per residential account were calculated from District data. These values were multiplied by the number of average commercial and residential accounts in each of the eight neighborhoods at each five-year interval to determine the annual electricity sales for that neighborhood. Recorded actual data for the five largest commercial customers were excluded from the overall District-wide average of commercial customers and dealt with separately. Finally, District-wide and neighborhood peak demand were calculated using estimated annual load factors. C. Data Sources Data for projecting District loads were obtained from several sources. District records were used to establish the commercial and residential customer counts and energy(kWh) sales for 1991. District personnel determined the number of commercial and residential accounts by neighborhoods based on meter routes. The Nevada County Planning Department-sponsored report entitled Land Use Proiections for the Truckee Community, John W. Cone, June 1989, (Cone Report) was used to estimate growth patterns for much of the commercial sector. The District-sponsored Truckee- Donner Public Utility Water System Masterplan, Sauers Engineering, Inc., December 1990, (Sauers Report) provided buildout information for much of the residential sector. Where these -2- reports did not have appropriate or adequate information, we made assumptions based on discussions with personnel at the Nevada and Placer County Planning Departments. ll. TRUCKEE COMMUNITY DEVELOPMENT In performing the analysis for this report, projections relied on the two long-range planning reports: the Cone Report and the Sauers Report. The Cone Report states that Nevada County is one of the most rapidly growing counties in the State with a 51% countywide increase in population between 1980 and 1989. The Truckee Community's permanent population is apparently growing at about the same rate. In the Electric System Master Plan, we have not reevaluated the conclusions of the two reports regarding growth. The projected growth patterns will significantly affect the capabilities of the District's electric distribution system. It should be noted, though, that planning over a 30-year time period has many inherent assumptions. Changes in one or several of these assumptions or other circumstances can significantly alter the projections. Ill. COMMERCIAL ENERGY ESTIMATE In 1991, the number of commercial accounts ranged from 740 to 780 electrical accounts, depending on the month. The District personnel counted a total of 761 commercial accounts,which is the number that was used in this analysis. The District's billing data indicates that 42,721,842 kWh were purchased by the commercial sector during the year. However, because there are five customers(with seven accounts)that utilize approximately 33%of the total commercial electric purchases, an average annual kWh per account analysis including them was not appropriate. Instead, analyses were separated for the large and the average commercial customers. A. Large Commercial Customers The fivedarge customers utilized 14,037,420 kWh in 1991. These customers include the Tahoe Truckee Sanitation Agency, Telchert & Sons, Tahoe Forest Hospital, Safeway and Lucky. Historical account data is retained for only the two previous years; so it is not -3- possible to evaluate their usage over a longer period of time. For the purposes of this study, the annual loads of these five customers were assumed to remain constant. Three new large customers may potentially be added at different times during the 30-year planning period. These facilities include a shopping center, a mail, and a regional USFS/CDF11_ocal fire management facility. Proposed electrical loads attributed to these new customers was estimated to total approximately 5,075,280 kWh per year. Their usages were assumed to also remain constant once they were added. Table 4 summarizes the electrical usage for the large commercial customers in their respective neighborhoods. As can be seen, these customers are located within the Gateway, Prosser and Airport neighborhoods. B. Average Commercial Customers The remaining 754 commercial accounts used 28,684,422 kWh in 1991. Thus the average commercial account used 38,043 kWh per year. Based on the District count, the 754 accounts were distributed in one of the eight neighborhoods. Growth in the number of these accounts was determined by using the estimated increase in commercial acreage development as defined in the Cone Report. The report indicates that within the District, 132.45 acres of land were used for commercial purposes in 1989. Moreover, the report states that the estimated increase in acreage would be approximately 38 to 43 acres per five-year interval. The Cone Report makes projections to 2010. Since the Electric System Master Plan projections must extend to 2020, the anticipated increase is assumed to remain constant at 43 acres in each of the last two intervals between 2010 and 2020. The resulting commercial growth is estimated to increase as follows: -4- Acreage Percent Interval Increase Increase 1991/1995 38 23% 1995/2000 38 22% 2000/2005 42 20% 2005/2010 43 17% 2010/2015 43 15% 2015/2020 43 13% These percentages were applied on the number of average commercial accounts in each neighborhood to project the number of accounts at each of the five-year intervals. The number of accounts was then multiplied by 38,043 kWh per year to determine the annual estimated electrical usage. Table 3 summarizes both the number of average commercial accounts and the average commercial electrical usage by neighborhoods. C. Total Commerclal Usage • t� For each neighborhood and for each five-year time interval, the estimated large commercial account usage was added to the average commercial account usage to become the total commercial electrical usage. Table 5 summarizes this information by neighborhoods. In 1991, the annual commercial electrical usage is 42,721,842 kWh,while in 2020, the annual commercial electrical usage is estimated to be 97,655,932 kWh. This increase corresponds to 2.9% increase per year, compounded annually. IV. RESIDENTIAL ENERGY ESTIMATE In 1991,.the number of residential electrical accounts ranged from 6,475 to 6,746 accounts, depending on the month. However, the District count indicated that there were 6,836 residential accounts. This variation is due to the fact that there are some District customers who _5_ receive water but not electricity; however, it is not a significant variation and, for the purposes of this report, the District count of 6,836 will be used. These accounts were distributed to each of the eight neighborhoods. Furthermore,the District records indicate that 47,407,660 kWh were used in 1991. Using 6,836 accounts, the average annual residential electrical usage is estimated to be 6,935 kWh per account. Growth in the number of accounts was determined by using both the Sauers Report and the Cone Report, The Sauers Report was used to define the number of residential units at buildout for the Gateway, OH/MVE, SMIPP/MWE and Prosser neighborhoods. Included in these buildout quantities are the estimated additional units that the report discusses in its Chapter 11, New Service Areas Within District Boundaries. Estimates of buildout in the Downtown, Donner Lake, and Airport regions were made following discussions with planners at both the Nevada and Placer County Planning Departments. For Tahoe Donner, the percentage increase from the Cone Report was used. It was assumed that Tahoe Donner would not reach total buildout for several reasons; some of the lots are unbuildable, some owners may buy lots for the amenities and never intend to build, and, lastly, as the area builds up, there may be resistance to additional building. Specific assumptions regarding each of the neighborhoods are as follows: Downtown This neighborhood currently has 482 accounts, which is assumed to be at 90% buildout. Furthermore, it is assumed that buildout, 536 accounts, will occur in 2020. An even growth distribution of nine accounts per interval is assumed to occur. Gateway This neighborhood currently has 514 accounts. In the Sauers Report, the neighborhood is estimated to have 861 residential units at buildout and an additional 272 residential units in the surrounding vicinity. The sum of these values indicates a total of 1,133 accounts, which is assumed to occur in 2020. An even growth distribution of 103 accounts per interval is assumed to Occur. -6- Olympic Heights/Martls Valley Estates This neighborhood currently has 240 accounts. The Nevada County Assessor's Parcel Maps indicate that there are 305 parcels available in these subdivisions, which would correspond to buildout. In the Sauers Report, an additional 200 residential units could be located in this vicinity. The resulting buildout value then becomes 505 accounts, which is assumed to occur in 2020, An even growth distribution of 44 accounts per interval is assumed to occur. Sierra Meadows/Ponderosa Palisades/Martiswood Estates This neighborhood currently has 654 accounts. Except for this initial value, the estimated number of accounts is taken directly from the Sauers Report. In that report, the buildout is estimated to be 1,993 accounts and to occur in 2015. Although Martiswood Estates does not now receive electric service from the District, it is within the proposed sphere of influence and is assumed to be served by the District. Prosser Areas/CoaclandfForest Service This neighborhood currently has 602 accounts. In the Sauers Report, the neighborhood is estimated to have 1,108 residential units at buildout and an additional 416 residential units in the surrounding vicinity. The sum of these values indicates a total of 1,524 accounts, which is assumed to occur in 2020. An even growth distribution of 154 accounts per interval is assumed to occur. Donner Lake This neighborhood currently has 1,269 accounts, which is assumed to be at 85% buildout. Furthermore, there are current approvals for an additional 200 parcels. Therefore, buildout is estimated to be 1,693 accounts and to occur in 2020. An even growth distribution of 71 accounts per interval is assumed to occur. Tahoe Donner This neighborhood currently has 3,075 accounts. The Sauers Report assumed that buildout would occur at 7,142 accounts and that it would occur in 2015. The Cone Report defines additional housing units for each interval;the resulting calculated percentage increases range -7- between 11% and 13% and result in a buildout of 5,982 accounts in 2020. For the purposes of this report, the Cone Report values were used. An even growth distribution of 485 accounts per interval is assumed to occur. * Airport This neighborhood currently has no residential electric accounts. However, the potential construction of Gooseneck Ranch is included in this analysis. Although Gooseneck Ranch is currently outside of the District's sphere of influence, there is a petition to include this area; therefore, it is included as if it were within the District's boundaries. It is also assumed that 100 of the residences will be constructed in 2000, another 150 in 2005, another 150 in 2010, another 100 in 2015, and the final 65 to buildout at 565 in 2020. Within each neighborhood area and for each five year time interval, the total residential electrical usage is estimated. Table 6 summarizes both the number of residential accounts and the residential electrical usage by neighborhoods. In 1991,the residential electrical usage is 47,407,660 kWh per year,while in 2020, the residential electrical usage is estimated to be 96,611,485 kWh per year. This increase corresponds to 2.5% increase per year, compounded annually. V. TOTAL ENERGY ESTIMATE AND SYSTEM PEAK Commercial electrical usage and residential electrical usage were added to obtain the total electrical usage in each of the eight neighborhoods. Table 1 summarizes this information. In 1991, the total electrical usage is 90,129,502 kWh per year, while in 2020, the total electrical usage is estimated to be 194,267,417 kWh per year. This increase corresponds to 2.7% increase per year, compounded annually. An analysis of the power purchased and the peak demand shows that the District's annual load factor is approximately 44%. Using annual load factor, the annual peak loads (kW) are calculated for each of the District's eight neighborhoods. Table 2 summarizes these results. As can be seen, these values increase from 23,384 kW in 1991 to 50,401 kW in 2020. -8- R.W.
