AEA Village Power System Survey 1990
ECO 061 Alaska Energy Authority DS - ALASKA ENERGY AUTHORITY VILLAGE POWER SYSTEM SURVEY ATQASUK \ POINT LAY KAKTOVIK POINT HOPE NUIQSUT @ ANAKTUVUK PASS @ SA Engineering, Inc. MECHANICAL AND ELECTRICAL CONSULTING ENGINEERS 2522 Arctic Boulevord, Suite 200 Anchorage, AK 99503-2516 Prone (907) 276-0521 Fax (907) 276-1751 FORWARD On October 30, 1989 and November 3, 1989 a site visit was made to review the power generation and distribution facilities in Anaktuvuk Pass, Atqasuk, Kaktovik, Nuiqsut, Point Hope, Point Lay and Wainwright, Alaska to determine the system deficiencies that will be required to be corrected to comply with the new Power Cost Equalization (PCE) requirements. In general, the power plants in all these villages are fairly new, very clean, and of very similar design. All the power plants are equipped with Caterpillar generators and modern switchgear. The generators range in size from 90 kW (Cat 3304 units) to 625 kW (Cat 3512 units) and the switchgear runs the range from manual aralleling systems with Sync Check permissive relays to fully automatic paralleling acilities. All the power plants utilize engine jacket water waste heat recovery to provide heat for the generator building and nearby public facilities. All the plants are well maintained, manned twenty four hours a day and equipped with Dranetz data loggers. All plant operators have been trained in operating generators in parallel and maintain daily plant logs. A new power plant was just recently completed and commissioned in Wainwright to replace the plant that was destroyed by fire in 1987. The power plant in Kaktovik in currently being remodeled to increase its generation capacity, the power plant in Point Lay is scheduled to be remodeled to increase its capacity in the spring of 1990, and the power plant in Anaktuvuk Pass is scheduled to be remodeled in 1991 although this facility is still in the project analysis phase. The power plants in Point Hope, Point Lay and Wainwright have power factors ranging from .7 to .85 while the plants in the rest of the communities have power factors in the .96 to .98 range. The systems in Point Hope, Point Lay and Wainwright need to be investigated to determine why the power factors are so low in comparison to the other communities. The reported system line losses for all communities vary from 9.2% to 34.7% with only one community having losses reported under 20%. These losses are excessively high and will not comply with the new PCE regulations which will calculate the PCE subsidy based on a maximum system line loss of 10% (including the station service). Based on the site visits, it appears that the great majority of reported line losses are due to a lack of metering for the station service, a large number of street lights and in some cases, services to schools, washeterias, community centers, etc. The Alaska Energy Authority should provide technical assistance to perform an investigation of the line losses in each community and to recommend corrections to the systems to reduce the line losses to a reasonable level.

THE POWER FACTOR WAS 98%. | | | ANAKTUVUK PASS Recommendations: Le The station service kWH meter is not working properly. Repair or replace it with a new one to accurately measure the power consumption of the power plant. The station service ammeter was reading 25.3A @ 480V at the time of the inspection. This gives a calculated demand load of 20.6 kW @ 98% power factor. The totalizing kW demand meter read 0.84 X 480 = 403 kW, the bus kW meter read 280 kW and a demand load calculation gave 281 kW. It appears that the totalizing kW demand meter has not been reset. Reset totalizing kWH demand meter monthly. There are 60 each 150 Watt high pressure sodium street lights in the village that are not metered. It is estimated that the total monthly unmetered street light load is approximately 3,285 kWH. This is a portion of the unmetered system losses, and is an eligible community facility cost for PCE subsidy. According to the monthly PCE reports, the system line losses for the years of 1987, 1988 and 1989 were: 45.8%, 33.9%, and 27.3%, respectively. The new PCE rules will calculate rates based on a 10% maximum total system loss, including station service. The Alaska Energy Authority will provide technical assistance to perform an investigation of the power system line losses. In compliance with AS 44.83.162(c)(1), and consistent with the administrative practices of the PCE program, a eal participating in the program is entitled to receive power cost equalization for sales of power to local community facilities, for actual consumption of not more than 70 kWH per month for each resident of the community. If the utility provides electric power at no cost to the local community facilities or to any of i its customers, that donated power is not eligible for PCE credits. North Slope Borough Utilities must collect all electrical billings to receive PCE credits. Black iron pipe must be used for fuel supply and return lines for fire safety. ANAKTUVUK PASS Summary: The generation efficiency is estimated at 13.3 kWH/gallon for the year 1988. All recommendations for this project relate to safety and code requirements, therefore, the generation efficiency will not be increased by performing this work. % of Generation Prorated Efficiency Construction kWH/Gallon Priority # lttem # Description Improvement __Cost__ _increase 1 1 Replace station service kWH meter 0.0% $2,774.00 0.0 2 4 Conduct power distribution system 0.0% 34,842.00 0.0 I line loss study 3 a Install a kWH meter to measure the power 0.0% 3,165.00 0.0 consumption of the street lights Subtotal 0.0% $40,781.00 0.0 Safety/Health/Code: 6 Replace fuel supply/return lines 0.0% 12,219.00 0.0 with black iron pipes TOTAL 0.0% $53,000.00 0.0 RURAL UTILITY POWERHOUSE INVENTORY Community: ANAKTUVUK PASS Utility: NORTH SLOPE BOROUGH Ywnership: NORTH SLOPE BOROUGH UTILITIE Contact: RILEY MORRY/ROOSEVELT PANEAK Date: 11/03/89 Phone: 661-3511 G-1 G-2 G-3 Operational?

IN GENERAL, THE POWER PLANT IS IN AN EXCELLENT CONDITION. 3. INSTALL STATION SERVICE KWH METER. 1, ATQASUK Recommendations: Install a station service kWH meter to measure the power consumption of the power plant. Totalizing kWH demand meter read 0.28 X 1,200 = 336 kW, the LED bus kW meter was reading 300 kW, the Dranetz unit was recording 260.7 kW and demand load calculations indicate 265 kW. It appears that the totalizing kWH demand meter has not been reset. Reset totalizing kWH demand meter monthly. There is about 13% difference in the demand load calculations and the LED bus kW meter’s reading. Recalibrate the LED bus kW meter to +2% during line loss investigation. There are 66 each 150 Watt HPS unmetered street lights in the village. It is estimated that the total monthly unmetered street light load is 3,614 KWH. This is a portion of the unmetered system losses, and is an eligible community facility cost for PCE subsidy. According to the monthly PCE reports, the system line losses for the years of 1988 and 1989 are: 53.5%, and 39.8%, respectively. The system line losses for these years are excessively high. The Alaska Energy Authority will provide technical assistance to perform an investigation of the power system line losses.

KAKTOVIK (Barter Island) Recommendations: 1, According to the monthly PCE reports, the system line losses for the years of 1988 and 1989 were: 40% and 53.2%, respectively. The new PCE rules will calculate rates based on a 10% maximum total system loss, including station service. The new PCE rules will calculate rates based on a 10% maximum total system loss, including station service. The Alaska Energy Authority will pode technical assistance to perform an investigation of the power system ine losses. There are 81 each 150 Watts HPS unmetered street lights in the village. It is estimated that the total monthly unmetered street light load is 4,435 kWH. This is a portion of the unmetered system losses, and is an eligible community facility cost for PCE subsidy. In compliance with AS 44.83.162(c)(1), and consistent with the administrative practices of the PCE program, a maliy participating in the program is entitled to receive power cost equalization for sales of power to local communi facilities, for actual consumption of not more than 70 kWH per month for eac resident of the community. If the utility provides electric power at no cost to the local community facilities or to any of its customers, that donated power is not eligible for PCE credits. North Slope Borough Utilities must collect all electrical billings to receive PCE credits. The powerhouse contractor will be installing buss kWH demand meter and station service meter as a part of the master control panel, included as a portion of the contractor. Black iron pipe must be used for fuel supply and return lines for fire safety.

NR NUIQSUT Recommendations: i According to the monthly PCE reports, the system line losses for the years of 1988 and 1989 are: 39.6%, and 33.9%, respectively. The new PCE rules will calculate rates based on a 10% maximum total system loss, including station service. The Alaska Energy Authority will provide technical assistance to perform an investigation of the power system line losses. Multiplier numbers are not indicated on the existing totalizing and station service kWH meters. Determine the proper multiplier for each KWH meter and note it on the face of the meter. There are 75 each 150 Watt HPS unmetered street lights in the village. It is estimated that the total monthly unmetered street light load is 4,106 kWH. This is a portion of the unmetered system losses, and is an eligible community facility cost for PCE subsidy. At the time of the inspection, the bus kW demand meter read 280 kW, the Dranetz unit read 284.6 kW and a on-site calculation indicated 303.8 kW. Verify that the bus kW demand meter, Dranetz unit and the bus ammeter are accurate. Recalibrate meters as necessary during line loss investigation. Sweat copper pipes are used for fuel pope and return lines instead of black iron. Replace sweat copper pipes with black iron pipe for fire safety. In compliance with AS 44.83.162(c)(1), and consistent with the administrative practices of the PCE program, a muy participating in the program is entitled to receive power cost equalization for sales of power to local community facilities, for actual consumption of not more than 70 kWH per month for each resident of the community. If the utility provides electric power at no cost to the local community facilities or to any of its customers, that donated power is not eligible for PCE credits. North Slope Borough Utilities must collect all electrical billings to receive PCE credits. NUIQSUT Summary: The generation efficiency is estimated at 11.3 kWH/gallon for the year 1988. All recommendations for this project relate to safety and code requirements, therefore, the generation efficiency will not be increased by performing this work. % of Generation Prorated Efficiency Construction kWH/Gallon Priority # Item Description Improvement Cost increase 1 1 Conduct power distribution system 0.0% $39,027.00 0.0 line loss study 2 3 Install a kWH meter to measure the power 0.0% 3,492.00 0.0 consumption of the street lights Subtotal ; 0.0% $42,519.00 0.0 Safety/Health/Code: 5 Replace fuel supply/return lines 0.0% 14,481.00 0.0 with black iron pipes TOTAL 0.0% $57,000.00 0.0 ALASKA ENERGY AUTHORITY PAGE: of PCE IMPROVEMENT PROGRAM DATE: 12-Jan-90 LOCATION: NUIQSUT , ALASKA PREPARED FOR RSA ENGINEERING FILE: NUIQSUT By Clark-Graves, Inc.

POWER PLANT HAS CONCRETE FLOOR W/METAL BUILDING. GENERATORS ARE ON SKIDS. 4. THE OPERATOR USES PLANT LOGS. 1. POINT HOPE Recommendations: According to the monthly PCE reports, the system line loss for the year of 1988 was: 14.7%. The system line loss for this year is excessively high. Also bad power factor. The new PCE rules will calculate rates based on a 10% maximum total system loss, including station service. The Alaska Energy Authority will Aaah technical assistance to perform an investigation of the power system ine loss. Install a station service kWH meter to measure the power consumption of the power plant. At the time of the inspection, the bus LED kW demand meter read 510 kW, the bus ammeter read 700A (570 kW @ 0.98 power factor), the Dranetz unit read 487.8 kW, and the totalizing kW demand meter read 0.76 x 960 = 729.6 kW. Reset totalizing kW demand meter monthly. Verify the accuracy of the bus ammeter and Dranetz unit and recalibrate as necessary during line loss investigation. There are 120 each 150 Watt HPS unmetered street lights in the village. It is estimated that the total monthly unmetered street light load is 7,560 KWH. This is a portion of the unmetered system losses, and is an eligible community facility cost for PCE subsidy. Sweat copper pipes are used for fuel supply and return lines instead of black iron. Replace sweat copper pipe with black iron pipe for fire safety. In compliance with AS 44.83.162(c)(1), and consistent with the administrative practices of the PCE program, a oe participating in the program is entitled to receive power cost equalization for sales of power to local communi facilities, for actual consumption of not more than 70 kWH per month for eac resident of the community. If the utility provides electric power at no cost to the local community facilities or to any of its customers, that donated power is not eligible for PCE credits. North Slope Borough Utilities must collect all electrical billings to receive PCE credits. POINT HOPE Summary: The generation efficiency is estimated at 9.4 kWH/gallon for the year 1988. All recommendations for this project relate to safety and code requirements, therefore, the generation efficiency will not be increased by performing this work. % of Generation Prorated Efficiency Construction kWH/Gallon Priority # Item # Description Improvement Cost increase 1 2 Install station service kHW meter 0.0% $3,081.00 2 1 Conduct power distribution system 0.0% 38,028.00 0.0 : line loss study 3 4 Install a kWH meter to measure the power 0.0 3,781.00 0.0 consumption of the street lights Subtotal 0.0% $44,890.00 0.0 Safety/Health/Code: 6 Replace fuel supply/return lines 0.0% 14,110.00 0.0 with black iron pipes TOTAL 0.0' $59,000.00 0.0 | | WOUWOUUWN NUNN N NNN a ome eo moe FUNVSSVSBSVRRRAVVSSBVRGRANSSwmnausuns 35 w oO 37 Rew =S0@e 42 UNUM PEPE h YRRRENLSSESRGRG ALASKA ENERGY AUTHORITY PAGE: of, PCE IMPROVEMENT PROGRAM DATE: 12-Jan-90 LOCATION: POINT HOPE , ALASKA PREPARED FOR RSA ENGINEERING FILE: PHOPE By Clark-Graves, Inc.

THE OPERATOR USES PLANT LOGS. 1 POINT LAY Recommendations: According to the monthly PCE reports, the system line losses for the years of 1988 and 1989 were: 27.6% and 31.9%, respectively. Also bad power factor. The new PCE rules will calculate rates based on a 10% maximum total system loss, including station service. The Alaska Energy Authority will provide technical assistance to perform an investigation of the power system line losses. There are 60 each 150 Watt HPS unmetered street lights in the village. It is estimated that the total monthly unmetered street light load is 3,285 kWH. This is a portion of the unmetered system losses, and is an eligible community facility cost for PCE subsidy. In compliance with AS 44.83.162(c)(1), and consistent with the administrative practices of the PCE program, a ae participating in the program is entitled to receive power cost equalization for sales of power to local community facilities, for actual consumption of not more than 70 kWH per month for each resident of the community. If the utility provides electric power at no cost to the local community facilities or to any of its customers, that donated power is not eligible for PCE credits. North Slope Borough Utilities must collect all electrical billings to receive PCE credit. The power house contractor will be installing buss KWH demand meter and station service meter as a part of the master control panel, included as a portion of the contractor. Black iron pipe must be used for fuel supply and return lines for fire safety. POINT LAY Summary: The generation efficiency is estimated at 10.5 kWH/gallon for the year 1988.
