Incorrect wiring of meters at several places. 2. Meters with incorrect voltage ratings at few places. 3. Some of the loads, such as power plant load, street lighting etc. are not metered. 4. Some of loads are not accounted for in the billing of NSB, for example, Sewer heat traces. 5. There are two Generators of 210 Kw rating and are run in parallel most of the time. The average load of the community is about 250 Kw. Consequently the generators run at about 59 % rating, causing uneconomical operation. 6. There are some unused transformers connected in the system, introducing iron loss. 7. There is no Totalizing meter in the power plant. 8. The panel in the store does not have a cover and pose safety hazard. 9. There are unpredictable voltage spikes in the School feeder. This might be due to a cable fault and needs investigation. Amit Sinha March 22, 1991 ANATUVIK PASS TABLE OF CONTENTS Introduction Executive Summary Field Trip Procedures Anatuvik Pass Field Trip Report and Recommendations Appendix A - Records Collected 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: 1. 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. LOAD ANALYSIS REPORT JOB NO. AP-05 Page 3 FIELD TRIP PROCEDURES: in Talk to the meter reader. A. Review record keeping and collect representative data B. Determine meter reading abilities C. Use records to indicate other loads that may have been missed and test if instrument class. D. Analyze records to find meters running backwards or misread. Check the wiring and test the meters at each of the following facilities: A. Powerhouse - Bus totalizing Station Laundry Water/ sewage & misc. or other powerhouse load B. School CG USDW (Combined School! District Warehouse) 4 meters D USDW - Warm Storage/Equipment Shop E Other Commercial Customers without self contained meters. Meter test procedure (3 phase loads) A. Record the meter CT & PT nameplates. B. Verify the wiring for specific Form of meter being used. -Check for unmetered loads C. Measure the voltage and current. -Measurements were taken using a Fluke 8060 RMS meter and Fluke 80:400 AC Coupler. D. Time a specific multiple of disk revolutions in seconds. = Compute the expected Kwh based on measured voltage & current, and compare against Kwh based on disk revolution times. F. Sketch one-line and note any code violations. Spot check all other commercial loads, street lights, verify residential loads, unrecorded loads, and meters which appear from the records to be working wrong. Inspect fuel meter and collect meter reading data. Visually inspect all of the outside plant and update the system as-builts. LOAD ANALYSIS REPORT JOB NO.

ANATUVIK PASS Page 3 SUMMARY OF FIELD TRIP FINDINGS Specific meter wiring problems A. Several 240V single phase meters are on 120/208 volt services at 3 phase banks (e.g. HVMF.) (7) B. At HVMF facility primary side wiring of CT's were backwards. We rewired secondaries to correspond. Meter appeared to run much faster afterward and did test correctly. It would be interesting to see if this meter starts recording a lot higher. Maybe even 4-5x higher. GC; NSB washeteria also has CT’s installed backwards. Meter on facility does correspond to meter in powerhouse on feeder. But tests we did were erratic, These CT’s should be rewired and new calibrated meter installed. D. Powerhouse village feeder totaling meter had both primary and secondary C phase PT wiring reversed. Meter reading problems A. Nunanamuit Corp. #1 (camp) meter has pointer’s which are hard to read. This would be a good meter to change out with a new calibrated meter. Unmetered loads A. Powerplant itself is not metered. B; Street lights are not metered. C. School meter should be on.lineside of transformer. Metered loads not being billed or accounted for properly A. NSB: allocation of sewer (heat trace) Poles 2,3,4 & 5, not being recorded. B. Meter SN 3415892 "Landis & Gyr." has multiple of 1 not 10 and affects sewer pole #4. Electrical code problems A. Fire department should have an outside main disconnect installed. B. Install cover on panel in store (Ref SN 64724806) ANATUVIK PASS Page 4 C. Fix broken ring on meter (Ref. SN45428943) store storage building 6. Other problems or suggestions A. Unpredictable spike (surge) on C¢school feeder may be indicative of underground cable failure. B. Village feeder appears to have 10-15% line losses. Some of this could be accounted for by unused transformer losses. These transformers should be disconnected. E.g. (3) 15 Kva transformers on new subdivision 19 line just running street lights. Cc Install bus totalizing meter and complete in telling of washeteria meter in powerplant. D. Start using and recording Dranetz readings on a regular basis. ANATUVIK PASS Page 5 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 a 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 ANATUVIK PASS 44,954 Kwhrs 0 121,877 29,488 196,319 9816 206,135 Kwhrs Page 6 on = 11/19 COMPARISON TO OTHER OPERATING DATA DRANETZ - This instrument appears to be working good but is not being used.

Fuel consumption will also_serve as a check against the kilowatt hour consumption data. Fuel Meter Readings 10/15 8am 20,147.2 11/19 8am 39.374.9 19,227.7 Based on dranetz total of 209.43 Kwhrs Fuel efficiency is 209,430/19,227.7 = 10.9 Kwhr/Gal Cat 3406 Generator are rated 210 Kw. Most of the time two generators are run in parallel. Average Kw for the test period is 249.3 Kw for an average load on these generators of 59%. (See Figure 4 in Kaktovik report for specifications) Cat 3406 fuel efficiency at 59% is 10.3 gal/hr + or - 5%. Even allowing for 5% these engines are performing about 10% less efficient than should be expected.
