The totalizing meter in the power plant has lost its accuracy and is reading 5 to 10% less than the actual. The associated instrument transformers are also not accurate for revenue metering. 2. Some of the meters are running backward due to incorrect wiring. 3. Some of the meters, for example at School, clinic and USDW panel D etc. are old pointer type and the meter reader has difficulty reading them. So a element of guess work gets into the systen. 4. The power plant does not have a station service meter. 5. Street lights and Laundry, which contribute a large load, are not metered. 6. There are about 19 houses that are either not metered or the meter reading do not appear in the PCE report. 5. Some of the commercial loads, owned by NSB are not reported for billing and not included in PCE report. 6. The Generators are operated in a uneconomical manner. Most of the time two generators are operated in parallel where as one generator would be sufficient to meet the load. 7. There are some over sized transformers contributing iron losses in the systen. Amit Sinha March 22, 1991 KAKTOVIK TABLE OF CONTENTS Introduction Executive Summary Field Trip Procedures Kaktovik Field Trip Report and Recommendations Appendix A - Records Collected Appendix B - Kaktovik Distribution System Line Loss Analysis INTRODUCTION On September 20, 1990 Raj Bhargava Associates (RBA) was issued a contract by the Alaska Energy Authority, Contract No. 2800286, Work Order No AEA-RAB-001, to perform a Line Loss Analysis in the North Slope Borough communities of Nuiqsut, Kaktovik, and Anatuvik Pass. AEA’s impetus behind this contract was to determine the causes of power losses which were reflected in the monthly reports filed by the North Slope Borough Public Utilities Department (NSBPUD) as part of the State of Alaska’s Power Cost Equalization (PCE) subsidy program, to recommend solutions to the problems discovered, and provide cost estimates of repairs. RBA was given the following specific directives: 4: Data Collection A) Collect PCE data and discuss known problems B) Coordinate with the North Slope Borough and each community 2, Field Trips A) Spot check consumer meters for accuracy B) Check for unmetered loads C) Check diesel powerhouse metering D) Check meter readers ability to read meters accurately E) Visual inspection of distribution system 3. Report A) Letter quality report in six copies with photographs, cost estimates, ACAD drawings and catalog cuts as appropriate. On October 11, 1990 this contract was amended to include an in- depth, computer-aided study of Kaktovik’s distribution system analyzing load flows, losses, voltages, and fault currents. During the weeks of November 14th and 21st, field trips were made by Thomas D. Humphrey, P.E. (RBA) to the North Slope Borough communities of Nuiqsut, Kaktovik, and Anatuvik Pass. Mr. Humphrey was accompanied by Mr. Frank Foote NSBPUD during all of the investigations. This document is RBA’s final report. The in-depth study of Kaktovik is attached as a separately bound appendix to this report. LOAD ANALYSIS REPORT JOB NO. AP-05 , Page 2 EXECUTIVE SUMMARY All of the line losses in these communities are identifiable and can be attributed to the following causes: 1. Unmetered loads The most significant unmetered loads were the NSB powerhouse station power, the NSB laundry/washateria, and the NSB street lights. 2. Unrecorded meters This category included NSB owned and operated facilities e.g. runway lights in one case. Often where buildings had been vacated and later reoccupied, the meter reading sheets had not been caught up with the current occupancy status. 3. Faulty meter wiring. Faulty wiring was suspected at locations which utilized current and/or potential transformers. All of these locations were checked. Problems encountered included reversed polarities, wiring for the wrong form, incorrect application of multiplying factor, and missing circuit closing contacts. For the most part all faulty meter wiring was corrected in the field during our investigations. 4. Normal system losses. In several instances transformers are considerably oversized. Reduction and/or elimination would result in savings. Long and/or undersized secondary runs also contribute to the overall systems losses. Fuel efficiency could be improved by utilizing a more precise schedule for maintaining units on line. Operator logs reveal that many times two units are kept on line when one unit would suffice.

Specific meter wiring problems Kaktovik has thirty-four commercial class consumers. Seven non-self contained instrument class meters are installed on the largest consumers. All seven were checked. A. The main bus totalizing meter reads from 5% to 11% low. This meter should be tested and recalibrated. It would be a good idea to replace the instrument transformers at the same time as the burden on the existing set may also be affecting the accuracy of this meter. B. The meter for NSB HVMF was wired correctly and tested correctly for Kwh but had the wrong multiplier being used (10)- it should be (1). The KW register did not test correctly. The available historical meter reading data for this meter is erratic. The meter should be replaced with a new KWH and KW cyclometer dial type meter. C. The meter for NSB USDW Panel B had some reversed wiring that we corrected. It will probably show more consumption now that wiring has been fixed. Of the remaining commercial meters, two of twenty-one, not counting unmetered sites, appear to be running backwards. D. KIC Fuel Stall meter 67880023 appears to run backward and should be replaced and sealed. May be because of pointer type dial being misread. E: Sim’s Office meter SN#32308962 was reportedly running backwards and should also be replaced and sealed. 2 Meter reading problems In trying to reconcile the meter readings we took during the inspection trip it became apparent that meters with pointer type dials are consistently being misread. It may also be that the meter reader occasionally estimates a reading for some reason. Estimated readings should be indicated somehow on the form perhaps by marking a capital "E" next to them and then verified as soon a practical. KAKTOVIK REPORT PAGE 5 Meters that are being misread include: A. NSB Health Clinic B. School GC; USDW Panel D The only sure way | know to correct this problem is to replace all of the pointer type meters with cyclometer or electronic type. 3. Unmetered loads The following loads do not have meters. Steps should be taken to install these meters as soon as possible. A. NSB Powerplant station power B. NSB Laundry C. NSB street lights. There are now 48 street lights. A meter should be installed for at least one of them and then used to estimate the total consumption. A typical street light is 150 HPS photo cell controlled. 4. Metered loads not being billed or accounted for properly In addition to the actual unmetered loads, there appears to be quite a discrepancy between the total number of metered loads and the number of loads that appear on PCE reports. New services, moves, and disconnects that have not travelled through the accounting system may account for some of these problems. There are 82 residential meters 19 of which | cannot account for from the records. A. All meters on all houses should be read each month and included on all meter reader reports regardless of whether the house is occupied or not. According to NSB PUD’s tariff there should be a minimum monthly billing of $15.00 generated for each meter until the homeowner requests a disconnect. If disconnected the meter should be pulled and the socket blanked off. B. Of the commercial loads the NSB itself is the biggest offender of non reported meters. Seven metered facilities are not being accounted for, i.e. not making it as far as PCE reports, as follows: NSB H.V.M.F. Heavy Vehicle Maintenance Facility NSB USDW Panel A NSB USDW Panel B NSB USDW Panel C NSB USDW Panel D KAKTOVIK REPORT PAGE 6 NSB Bulk Fuel Facility - Bulk fuel facility out at the edge of town halfway to airport appears to have 3 lights and some electric heat run all the time. KIC Fuel Station (Not to be confused with KIC Fuel Storage) 5! Electrical code problems Three minor problems were observed: A. Fire dept needs outside building disconnect switch While not specifically stated in NEC Article 230-70(a) it is common practice to require an outside of the building service disconnect switch. The service disconnect switch for this building is inside a inaccessible room. B. Drain pipe over F&W meter There appears to be some type of drain pipe immediately above the service equipment which | feel is in violation of NEC Article 230-54(g). C. Housekeeping in the Power Plant/Washateria Laundry panel needs filing cabinet moved from in front of it. NEC Article 110-34 requires 3 feet of working space in front of this panel. 6. Other suggestions A. Need to start program of utilizing Dranetz record at powerplant. Need supply of paper for it. B. Laundry creates a load problem when dryers come on too fast which could be solved by timers. This is a 105KW load. (5 dryers) C. DEW line should be planned to become a system load. DEW line generator runs runway lights as well as DEW line facility. D. Develop a program of systematically replacing meters with calibrated ones. Install meter seals and locks on all meters. [= Add readings in the powerhouse to the meter readers monthly recording duties. This will soon include bus totalizing meter, laundry, station power, and village feeder meters. The fuel meter should also be read to coincide with all the other meters as of the same day. KAKTOVIK REPORT PAGE 7 RECONCILIATION OF TOTAL KILOWATT-HOURS FOR A TEST PERIOD BASED ON ALL METERED LOADS AND ESTIMATES OF UNMETERED LOADS. The NSBPUD has a policy of reading meters on each Monday of the third week of each month. The most recent meter reading period is for the 35 day cycle 10/15/90 through 11/19/90. This reconciliation of total kilowatt-hours will use this period as the test period. Data is also available for the two preceding months and from first quarter PCE reports. As well as the inspections and tests performed this meter history was analyzed for all meters for accuracy and completeness. All loads were then classified into the following groups: Table 1 - Residential meters which operate correctly and are correctly read and accounted. Table 2 - Residential meters which are not correct for one or more reasons indicated. Estimates for the test period are included. Table 3 - Commercial meters which operate correctly and are correctly read and accounted. Table 4 - Commercial meters which are not correct for one or more reasons indicated. Estimates for the test period are prepared. This data is summarized as follows: Residential Loads - Table 1 Table 2 Commercial Loads - Table 3 Table 4 Sub Total Allowance for system losses of 5% Total KAKTOVIK REPORT 37,509 Kwhrs 5,500 32,893 100,340 176,242 8.812 185,054 Kwhrs PAGE 8 COMPARISON TO OPERATING DATA Fuel records for the same period: 11/19 1213881 10/15 1199892 14989 gallons Based on predicted fuel efficiency for this test period of 12.34 to 12.85 kwhrs per gal. Kwhrs produced range 184.9Mwhrs to 192.6Mwhrs. The bus totalizing meter for the same period: 11/19 915 10/15 772 143 x 1200(MF) = 171,600Kwhrs After adjustment for the 5% to 11% error in this meter this total would range 180.2 Mwhrs to 190.5 Mwhrs.

Fuel consumption will also serve as a check against the kilowatt hour consumption data. In order to cross check the kilowatt hour consumption data it is necessary to determine the expected fuel consumption. This | have computed for the test period 10/1/90 through 10/31/90. Hourly total kw generated was gathered from the meter readers daily logs. This plant was operated very efficiently with usually only one generator (#1 or #3 during the day) being run at a time and during the graveyard shift usually the smaller generator (#5) was run. Table 5 summarizes this total generation peak load per hour for the test period. Fig 1 illustrates daily load curves for typical weekday days and weekend days. Fig 2 illustrates typical load duration curves for this data. Tables 6 and 7 contain the data and calculations to determine the expected fuel efficiency for this particular combination of load duration and engine-generator fuel efficiency. Manufacturer’s performance data is illustrated in Figures 3 and 4. Figure 3, Cat 3406B corresponds to generator units #1 and #3. Figure 4, Cat 3406PCTA corresponds to unit #5) Since unit #5 is less efficient than units #1 & 3, Cat 3406B performance data was utilized for all the calculations. These calculations indicate that the expected fuel efficiency of these units operated as indicated for the month of October 1990 should be 12.85 Kwhrs / gallon. This is also based on the assumption that the fuel used was 19590 BTU/Lb and that any additional power required by the heat recovery system was negligible. | estimate error due to these factors at plus 0% to minus 4%. The October 1 fuel meter reading was 1206540. The October 31 fuel meter reading was 1194326. Fuel consumption for the thirty day period is 12214 gallons. Errors due to differences in timing of the daily filling of the day tank and recording of the readings seem negligible. However the accuracy of the fuel meter itself is also probably not better than plus or minus 2%. Expected Fuel Efficiency = 12.85 (12.85 - 12.34) kwhrs/gallon Fuel Consumption = 12214 (12458 - 11970) gallons Calculated Kwhrs produced = 156950 (147710 - 160085) Kwhrs KAKTOVIK REPORT PAGE 14 The powerplant’s bus totalizing meter indicated production of (835 - 718)* 1200 = 140400 kwhrs. Allowing for errors due to misreading the units digit of 1% and inherent accuracy of 2% would yield a range of (144612 - 136188). The highest kwhr metered reading range is still below the lowest fuel meter calculated range by 2% and is 11% low based on the predicted values. Recommendation and conclusion: In this particular case | tend to trust the fuel meter over the kwhr meter and feel that the kwhr meter is reading between 2 and 11 percent low and probably closer to the 11%. This conclusion is supported by the estimated total load and by ampacity tests taken on the CT’s secondary windings. is The existing Dranetz recorder should be regularly utilized to verify kilowatt-hour production. 2: The existing Kilowatt hour meter should be replaced with one that has been tested and calibrated. 3. The existing CT’s and PT’s should be tested and calibrated with a known reference standard. KAKTOVIK REPORT PAGE 15 TABLE 5 (KAKAVG.
