In general, the power plants in all these communities are in fair condition and well maintained. The power plants are equipped with Caterpillar, John Deere, or Cummins generators as follows: 1. Chignik Bay, Egegik and Pilot Point power plants are equipped with Caterpillar oo The generators range in size from 55 kW (Cat 3304) to 220 kW (Cat 3406). 2. Chignik Lake, Ivanoff Bay, and Perryville power plants are ey with John Deere generators. The generators range in size from 50 kW to 175 units. 3. Port Heiden power plant is equipped with a 120 kW (Cummins unit) and 75 kW Horse power limited (Cummings) unit. The generator control panel consists of a manual paralleling system with sync check permissive relays. The property the power plant in Egegik is located on is not owned by the utility. The land owner refuses to allow the utility to do any further construction on the land. The utility is in process of procuring a new for the site power plant. The power plant in Egegik has power factor of .94 while the power plants in the rest of the communities do not have power factor meters in their switchgear. The reported system line losses for the communities vary from 7.3 to 18% which is based on monthly kWH generated and sold. We were unable to compute line losses for all communities due to the incomplete monthly PCE Reports for some of the communities. Theses losses are high and will not comply with new PCE regulations which will calculate the PCE subsidy based on a maximum system line loss of 10% (including the station service). ased on the site visits, it appears that the great majority of reported line losses are due to ae od readings, meters that are not working properly, unmetered street lights, etc. e Alaska Energy Authority should provide technical assistance to perform an investigation of the line losses in each community and recommend corrections to the systems to reduce the line losses to a reasonable level and to increase generation efficiency. 45KVA-480/208V STEP-DOWN TRANSFORMER TOTALIZING KWH DEMAND THE SUBSTATION CONSISTS OF METER.

GENERATOR SWITCHGEAR IS MADE BY CONTROLLED POWER, INC., 95TH ST., REDMOND, WA. 98052. 14798 N.E. 1s CHIGNIK BAY RECOMMENDATIONS: Community loads are higher on Phase C than Phase A and B. The calculated load imbalance is about 33%. Rebalance community loads by shifting some Phase C loads to Phase A and B. According to the monthly PCE report, the annual system line loss for the years of 1987, 1988 and 1989 are: 0.4%, 0%, and 1.1%, respectively. At the time of the inspection, the total calculated demand load was 80 kW. According to the monthly PCE report the peak loads for these years are 57.9 kW, 41.6 kW and 53.3 kW, respectively. There is a 38% to 92% difference in the demand load calculation and these readings. Therefore, the annual system line losses for these years are unrealistic. is might be an indication of power house kWH meter malfunction. There are 13 each 150 watt unmetered mercury vapor street lights in the community. It is estimated that the total monthly unmetered street light load is 712 kWH. This is a portion of the unmetered system losses, and is an eligible community facility cost for PCE subsidy. Totalizing kW demand meter is not working properly. Repair or replace it with a new one (See item 2 above). Demand load calculations indicate a demand of 80 kW. The master control panel read 149A at 481V or 99 kW. There is a 24% difference in demand load calculations and the bus amp meter’s reading. Recalibrate the bus Amp meter to +2% during the line loss investigation. Train the operator on how to most efficiently operate the power plant and in the use of plant logs to enhance preventative maintenance, tracking parts cost, and fuel and oil consumption. Using the right size generator to serve the community loads can increase generation efficiency. Generators are older but well maintained, clean and neat. Operator appears to be doing a good job. Current production efficiency show 9 kWH per gallon. When metering problem is solved, the kWH per gallon should improve (i.e. all KWH will be measured accurately). CHIGNIK BAY Summary: Present generation efficiency is estimated at 9.0 kWH/gallon. The totalizing kWH demand meter needs to be replaced or repaired and the bus Amp meter needs to be recalibrated. When metering problem is solved, the kWH/gallon should improve. % of Generation Prorated Efficiency Construction kWH/Gallon Priority # Item # Description Improvement Cost increase 1 4 Replace totalizing kWH meter to provide 0.0% $ 4,466.00 0.0 accurate readings 2 5 Recalibrate the LED bus Amp meter 0.0% 3,061.00 0.0 to provide accurate readings 3 6 Train the operator to improve the 0.0% 8,285.00 0.0 monthly PCE report with accurate readings 4 1 Rebalance phase loads 0.0% 7,188.00 0.0 TOTAL 0.0% $23,000.00 0.0 ALASKA ENERGY AUTHORITY PAGE: of, PCE IMPROVEMENT PROGRAM DATE: 05-Jul-90 LOCATION: CHIGNIK BAY , ALASKA PREPARED FOR RSA ENGINEERING FILE: CHIGNIK By Clark-Graves, Inc.

The substation consists of three 25 kVA, 120/208V, "Y" - 7.2/12.47 kV, "Y", 3-phase, 4-wire oil filled transformers cluster mounted on a pole. There are two 125 kW and one 50 kW generators. Generators and control panels are well maintained and owned by the School District. The monthly PCE reports for the year of 1989 are not complete because of poor record keeping by the Community Utility Manager. Therefore, the annual system line loss, generation efficiency, and peak and low loads can not be computed.

POWER PLANT HAS CONCRETE FLOOR W/WOOD CONSTRUCTURE BLDG. IT HAS AN EMERGENCY LIGHT & A FIRE EXTINGUISHER @ EXIT DOOR. THE POWER PLANT IS CLEAN & IN A FAIR CONDITION. THE PLANT OPERATOR DOES NOT USE PLANT LOGS. THE POWER PLANT IS OPERATED IN WINTER MONTHS DURING SCHOOL YEAR. 2. GENERATOR CONTROL PANEL WAS MADE BY PACIFIC DIESEL COMPANY. CHIGNIK LAKE (School) RECOMMENDATIONS: i Data is not available for 1987 and 1988 as the utility was not brought into operation until the spring of 1989. Community loads are higher on Phase A than Phase B and C. The calculated load imbalance is 61.5%. Rebalance community loads by shifting some Phase A loads to Phase B and C when school is on-line. School does not meter its own consumption which will affect kWH per gallon conversion. Install a totalizing kWH meter to measure all production of the power plant. It will be helpful to the operator to select the right size of generator to be on-line, and the information will be needed to determine true kWH per gallon efficiency. Install a station service kWH meter to measure the power consumption of the power plant to determine operating costs. Multiplier numbers are not indicated on community and school kW demand meters. Track down the as-built drawings and shop drawings to obtain the multiplier and indicate on meter face. There are 10 each 100 watt unmetered mercury vapor street lights in the community. It is estimated that the total monthly unmetered street light load is 365 kWH. This is a portion of the system losses, and is an eligible community facility cost for PCE subsidy. Five 8,500 gallon bulk storage tanks are presently setting on the ground without a diked containment. Relocate the five fuel storage tanks, and install a dike to contain possible spills. CHIGNIK LAKE (SCHOOL) Summary: Present generation efficiency is estimated at 7.7 kWH/gallon.

Indicate on meter face. The monthly PCE reports of the years of 1987, and 1988 are not complete as the information was not required until 1989. Annual system line loss, generation efficiency, peak and low load cannot be computed due to the lack of information. Records for 1989 reflect inaccuracy in either kWH generated or sold. The line loss shows 17-18% in May and June 1989 while generation efficiency shows 12.1 kWH per gallon. These figures are inconsistant with common utility practice. The totalizing kW demand meter reads 0.28 x 800 = 224 kW. The demand load calculation gave 101.0 kW. It Pe that the totalizing kW demand meter has not been reset. Reset totalizing kW demand meter monthly. Existing outgoing main feeder is een laid on the ground and up the pole to 3-50 kVA cluster mounted oil filled transformers. This is an extremely dangerous installation to the public. Install the exposed outgoing main feeder in conduit ( — }) and up to the pole riser or through a weatherhead to the step up bank e existing wiring is in violation of NESC - 231. Two 8,500 gallon, one 8,000 gallon and one 3,600 gallon bulk storage tanks are pia setting on the "ground without a dike containment. Relocate the bulk el storage tanks, and install a dike to contain possible spills. The generator frame is not omic and an ym ground conductor is not installed at generator control panel #1 and 2. Provide and install system ground in accordance with NESC-9SA for plant safety. Inside Power Plant: Install all unprotected wires or cables in conduit to protect energized cables. Install diamond steel plate on the floor for a minimum of 12 inches around each oe in accordance with NFPA-37 to prevent oil from spilling through gravel oor (Typical of 2) Install a new fuel meter on the daytank to measure the fuel consumption. Remove unused generator control panels and abandoned conduit and wires. Install a cover plate for the switch located below the battery charger. Install a dike around the daytanks to contain fuel spills. Train the operator on how to most efficiently operate the power plant and in the use of plant logs to enhance preventative maintenance, tracking parts cost, and fuel and oil consumption, Using the right size generator to serve the community loads can reduce fuel consumption. 14. 15. 16. AT. There are 26 each 175 watt unmetered mercury vapor street lights in the ii It is estimated that the total monthly street light load is 1,661 kWH. is is a portion of the system losses, and is an eligible community facility cost for PCE subsidy. Install an emergency light in the power plant. The property the power pen is located on is not owned by the utility. The land owner refuses to al the utility to do any further pi set p on the land. The utility is in the process of procuring a new powerhouse site. At that time, a new plant will be constructed consisting of a pre-engineered metal building with a concrete floor. The power house is pad locked to keep unauthorized people from getting into the power plant. EGEGIK Summary: Present generation efficiency is estimated at 10.2 kWH/gallon. All requirements for this project relate to code, safety/health, and training 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 9 Install fuel meter on the day tank 0.0% $ 736.00 0.0 2 13.

Enroll Ivanoff Bay in the PCE program to benefit from technical assistance, training program, etc. Community loads are higher on Phase C than Phase A and B. The load imbalanced is about 83.3%. Rebalance community loads by shifting some Phase C loads to Phase A and B when school is on-line at time of reconstruction. Install an instantaneous kW meter. pn 3 lg cover plates to be installed as the operator’s duty to avoid wires or cables from being exposed. The power plant does not have a fire protection system. Provide a 10 pound fire extinguisher in the power plant at each exit door (total of 2). ye an emergency light inside the power plant at each exit door (total of 2). Install a dike around the daytank to contain fuel spills. Two 10,000 gallon bulk storage fuel tank are presently mounted on wood skids without a diked containment. Relocate the two fuel storage tanks, and install a dike to contain possible spills. At main 200A double pole, double throw manual transfer switch, replace the existing spliced ground conductor with a new unspliced conductor. Train the operator on how to most efficiently operate the power plant and in the use of plant logs to enhance preventative maintenance, tracking parts cost, and fuel and oil consumption. so, train the community utility manager to report accurate readings. IVANOFF BAY Summary: Present generation efficiency is unknown. All requirements for this project relate to code, safety/health, and training requirements, therefore, the generation efficiency will not be determined and will not be increased by performing this work. % of Generation Prorated Efficiency Construction kWH/Gallon Priority # Item # Description Improvement Cost increase ll 3 Install instantaneous kW meter 0.0% $ 1,838.00 0.0 2 10 Train the operator to record the monthly 0.0 6,647.00 0.0 PCe report with accurate readings Subtotal 0.0% $ 8,485.00 0.0 Safety/Health/Code: 9 Replace existing splicing ground conductor 0.0 1,944.00 0.0 @ main transfer switch 6 Install emergency lights 0.0 2570500 0.0 5 Install fire extinguishers 0.0 .00 0.0 7 Install a dike around the day tank 0.0 6,550.00 0.0 8 Install dike around bulk storage tanks 0.0 110,506.00 0.0 2 _Rebalance phase loads 0.0 5,801.00 0.0 TOTAL 0.0% $136,000.00 0.0 ALASKA ENERGY AUTHORITY PAGE: of.

The substation consists of a 100 kVA, 120/208V, "Y" pad-7.2/12.47 kV, Y 3-phase, 4-wire oil filled transformer on a poly pad. There is one 175 kW, one 170 kW, and one 50 kW generators. There is also one burned up generator of unknown size. Generators and switchgear are in fair condition. The monthly PCE Reports for the years of 1987, 1988 and 1989 are not complete because of poor bookkeeping by the community utility manager. Therefore, the annual system line loss, generation efficiency, and high and low average loads cannot be computed. FUEL METER IN A WOODEN 2-DAY TANKS ARE ON BOX A WOODEN PLATFORM.

GEN #4: LISTER #1613HR4A28, 1800 RPM, 50KW, 208V. S/N IS UNMARKED. CURRENT HR: 2.2. GEN #4 IS OPERATIONAL & USDE IN SUMMER MONTHS. PERRYVILLE RECOMMENDATIONS: 1. Install a station service - kWH meter to measure power consumption of the power plant. 2. Install a totalizing kW demand meter to measure all production of the power plant and determine true kWH per gallon. 3. Community data is incomplete in the monthly PCE reports for the years of 1987, 1988 and 1989. Therefore, the system line loss for these years can not be computed. Train the plant operator and/or community utility manager to most efficiently operate the power plant and in the use of plant logs to enhance preventive maintenance, tracking part costs, fuel & oil consumption. 4. Generator #3: A. Generator Control Panel (remoted mounted) o KW demand meter is not working properly and its multiplier number is incorrect. Replace with a new kW demand meter with the proper multiplier. o AMP meters read: 60A, 270A and 10A. A total demand load calculation gave 32.6 kW assuming an .8 power factor. B. nit mounter genset meter o AMP meter read: 20A, 140A and 20A, 240V. Total demand load calculation gave 20 kW at assuming an .8 power factor. There is 63% difference in generator control panel and unit meter genset’s value. Recalibrate the unit mount genset meter and the generator control panel to +2% during the line investigation. 5. Fence two exterior daytanks (1,000 gallon each). Install a 50 gallon day tank with fuel meter inside the bso plant. Install a chain link door with pad lock to prevent fuel pilferege, and pad lock valves on daytank and fence. 6. Remove the broken emergency light, and install a new one in its place. 7. Install a 10 pound fire extinguisher at power plant’s exit doors (total of 2). 8. Community loads are higher on Phase B than Phase A and C. The calculated load imbalance is about 600%. Rebalance community loads by shifting some Phase B loads to Phase A and C when the school is on line and after new housing project is completed. 9. One each 2,000 gallon, 4,000 gallon and 20,000 gallon bulk fuel storage tanks are presently setting on the ground without a diked containment. Relocate the bulk fuel storage tanks, and install a dike to contain possible spills and fence with lock for security. PERRYVILLE Summary: Present generation efficiency for the month of July, 1988 was 10.3 kWH/gallon. All requirements for this project relate to code, safety/health, and training 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 Install station service kWH meter 0.0% $ 1,770.00 0.0 2 2 Install totalizing kW demand meter 0.0 2,591.00 0.0 3 4 Recalibrate genset 0.0 7,222.00 0.0 4 8 Rebalance phase load 0.0 4,318.00 0.0 5 3.

POWER PLANT HAS CONCRETE FLOOR W/WOOD FRAME WOOD BLDG. IT HAS AN EMERGENCY LIGHT AND A FIRE EXTINGUISHER AND EXIT DOOR. THE POWER PLANT IS CLEAN AND IN GOOD CONDITION. 2. THE PLANT OPERATOR DOES NOT USE PLANT LOGS. PILOT POINT RECOMMENDATIONS: a Community loads are higher on Phase A than Phase B and C. The calculated load imbalance is about 125%. Rebalance community loads by shifting some Phase A loads to Phase B and C when school is on-line. The monthly PCE reports for the years of 1987 and 1988 are not complete as the information was not required until 1989. Due to lack of data for these years, the annual system line loss, generation efficiency, peak and low load cannot be computed. Records for 1989 reflect inaccuracies in either fuel, kWH generated or sold. Generation efficiency is 6.4 KWH per gallon which is unacceptably low. There are 4 each 175 watt unmetered mercury vapor street lights in the community. It is estimated that the total monthly street light load is 255 kWH. This is a portion of the system losses, and is an eligible community facility cost for PCE subsidy. Train the operator on how to most efficiently operate the power plant and in the use of plant logs to enhance preventative maintenance, tracking parts cost, and fuel and oil consumption. Using the right size generator to serve the community loads can reduce Scum Demand load calculations indicate a demand of 34.6 kW. The totalizing kWH meter recorded 889.8 x 120 = 106,964 kWH. The 100 kW Cat generator was on-line at the time of the inspection because the 55 kW Cat generator was down for service. Rewire the dual ratio CT’s for the totalizing kWH meter from 600:5, to 300:5 to provide mid-scale indication. Multiplier will change from 120 to 60. One 20,000 gallon bulk fuel storage tank is on grade without a diked containment. Relocate the bulk fuel storage tank, and install a dike to contain possible spills. PILOT POINT Summary: Present generation efficiency is estimated at 6.4 kWH/gallon. All requirements for this project relate to code, safety/health, and training 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 5 Rewire dual ratio CT’s 0.0% $ 7,899.00 0.0 2 4 Train the operator to improve the 0.0 7,417.00 0.0 monthly PCE report with accurate readings Subtotal 0.0% $ 15,316.00 0.0 Safety/Health/Code: 1 Rebalance phase loads 0.0 6,435.00 0.0 6 Install dike for bulk storage tanks 0.0 108,249.00 0.0 TOTAL 0.0% $130,000.00 0.0 ALASKA ENERGY AUTHORITY PAGE: of PCE IMPROVEMENT PROGRAM DATE: 05-Jul-90 LOCATION: PILOT POINT, ALASKA PREPARED FOR RSA ENGINEERING FILE PILOT By Clark-Graves, Inc.

Using the right size generator to serve the community loads can reduce five] eomiettenistiegs There are 22 each 175 watt unmetered mercury vapor street lights in the community. It is estimated that the total monthly street light load is 1,405 kWH. This is a portion of the system losses, and is an eligible community facility cost for PCE subsidy. According to the plant operator, both generators are equipped with under sized fuel injectors. Replace with right size as the load profile dictates. One 7,500 gallon and one 2,000 gallon bulk fuel storage tanks are on wood skids without a diked containment. Relocate the two bulk fuel storage tanks, and install a dike to contain possible spills. Install a coverplate for junction box. PORT HEIDEN Summary: Present generation efficiency is estimated at 11.1 kKWH/gallon. All requirements for this project relate to code, safety/health, and training 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 3 & Recalibrate totalizing kW demand meter 0.0% $ 4,044.00 0.0 8 and miscellaneous 2 4 Train the operator to improve the 0.0 5,877.00 0.0 8 6 Replace fuel injectors 0.0 8,718.00 0.0 Subtotal 0.0% $ 18,639.00 0.0 Safety/Health/Code: 1‘ Rebalance phase loads 0.0 5,220.00 0.0 7 Install dike for bulk storage tanks 0.0 88,141.00 0.0 TOTAL 0.0% $112,000.00 0.0 ALASKA ENERGY AUTHORITY PAGE = of PCE IMPROVEMENT PROGRAM DATE: 09-Jul-90 LOCATION: PORT HEIDEN, ALASKA PREPARED FOR RSA ENGINEERING FILE HEIDEN By Clark-Graves, Inc.
