There are some small corrections, however, that should be made before multiple copies are made. 1. Correct the date on the front cover. 2. Since there is a map on the front cover, put a small star on the map in the location of the village being studied. 3. Delete the Average Outage Rate from the numbers presented at the bottom of page I of the Executive Summary. 4. On future reports the photos should be in color. To avoid astronomical reproduction costs the photos should be on a limited number of pages with photos only rather than scattered within the text. On this report only the photographs may be left where they are and reproduced in black and white. 5. In the Concept Design Drawings show the primary piping in red, the arctic piping loop in orange or purple, and the user building connections in blue. 6. Correct the figure numbers for figures V-4 and V-5. 7. The 0.2 on the last line of the third paragraph on page 24 should either be followed by a percent (%) sign or it should be changed to 0.002 to make the calculation correct. 8. Delete the bottom half of Table IX-A on page 45. It currently makes it look as if the heat lost from the distribution piping is being counted as used rather than lost. 9. Delete the words "Pipe Loss" from the legend of Figure IX-1 on page 46, and correct the figure if this is in fact what it depicts. Piping losses should be reflected by a decrease in available waste heat rather than an increase in heat demand. 10. Add the word "heat" between "waste" and "off" in the first line of the Project Summary on page 47. 11. We require 15 copies of the report as well as an unbound master copy. Please make this number of copies on this and future final reports only if it is possible without exceeding the remaining allowable expenses for the work order. If this many copies cannot be made with the remaining allowable expenses then let me know and submit just the 6 copies originally agreed upon. 12.

The bound report goes into more detail on how the failure rates were determined than is required for the waste heat reports while the submitted Koyuk section is too general. Present the Failure Analysis section in the following format in each of the waste heat reports: I. FAILURE ANALYSIS A. General (Put section introduction here) B. Identification of Major Components (One paragraph descriptions of each major component) C. Failure Mode and Impact (Provide subsections for each major component as follows) Component Failure Mode: (Describe ways in which component is likely to fail) Generator Operational Impact: (Describe effect of component failure on power plant) Waste Heat System Operational Impact: (Describe effect of failure on waste heat system) Environmental Impact: (Effect on environment) Required Immediate Actions: (Describe actions to be taken by operator to prevent further damage until repair crew arrives) D. Failure Frequency and Cost (List assumptions made regarding the repair and then provide subsections for each major component as follows) Component Most common failure: (One line description of most likely means of failure) Frequency of Occurrence: (Occurrences per year) Repair Cost: (Cost per Occurrence) Estimate of Down Time: (Number of days) Effects of System Life on Frequency: (One line description of wearing effects) E. Design Decisions (Indicate conclusions drawn from failure analysis) The major components listed should include circulating pumps, jacket water heat exchanger, radiators, control valves, arctic piping, interior piping/valves, and any other key pieces equipment. Do not make editorial comments about the village politics in Noatak or anywhere else. polarconsult alaska, it 1503 West 33rd Avenue e Suite 310 ANCHORAGE, ALASKA 99503 (907) 258-2420 om eee WE ARE SENDING YOU C) Shop drawings J Copy of letter FAX (907) 258-2419 [) Attached LETT OF TRANSMITTAL 3-20 7 u.lle ye > _totn Br thous RECEIVED buns © YU 1990 t ALASKA ENERGY AUTHORITY, {J Under separate cover via_____.____the following items: © Prints C] Plans O Samples C Specifications {) Change order ae as 1 | Mavely Failure Aunalysss — Repo? . / Faslre Anelyse& Sooo Koyuk THESE ARE TRANSMITTED as checked below: CL For approval (J For your use (J As requested C) For review and comment (] FOR BIDS DUE REMARKS Zs fs m hin - Wil have Fine Drott- jo mlonyors koyuk — next day doth Kiveling -.

Korn, VI. Failure Analysis A. Operation and Maintenance The following assumptions have been made with regard to operations and maintenance: 1. The on-site operator will act as a caretaker only. 2. All repairs will be made by skilled mechanics from Anchorage or Fairbanks. It is assumed that the mechanic will travel by jet to Nome and hence on a charter to Koyuk. This would take one day during the summer and up to two days during the winter, assuming bad weather conditions. 3. A skilled crew will visit the site three times per year to perform preventive maintenance. Operation of the system will primarily be under control of thermostats mounted on the return distribution line. Return water temperature will control the pumping Tate to keep the temperature within a set range. An alarm system will be connected to the distribution pipe to indicate the presence of moisture inside the jacket. The alarm system can also be used to determine the location of the failure. In addition to reading the alarm system for a specific incident, the roving maintenance crew will read the system during normal visits three times per year. As the on-site operator is to act as a caretaker only, that person's function will be to shut down the affected portion of the system and close valves if a failure occurs. He or she will also notify maintenance personnel. Depending on skill, on- site maintenance personnel may be authorized to replace a circulation pump, tighten bolts on a heat exchanger, and replace valve packings, as well as recharge the system if there is a slow leak of fluid. B. Failures A district heating system can be reliable if properl: igned and constructed. Piping systems are among the most reliable ways ‘to_of-transporting a material. To prevent internal corrosion of the steel carrier pipe, district heating systems will use inhibited glycols and water. The level of inhibition will be checked. Corrosion coupons may be placed in the pipe which will indicate whether the pipe is corroding. The outside of the steel pipe is protected by a very tough non- corrosive external jacket. With an operational alarm system, failure of the external jacket at any location will be known, allowing actions to be taken to repair the problem before serious corrosion of the metal carrier pipe occurs. Teecsiaion Possible modes of failure include: - Dig-ins - Pipe or valve failure in power plant. As the district heating system is separated from the generation system by the heat exchanger, failures of the plant piping will be localized. - Pipe failure due to corrosion. - Power outage, loss of heat. - Heat exchanger failure, plate type and exhaust heat recovery type. - Distribution pump failure (including spare). Eff cal wa ot : The district heating system will connect to the existing cooling system off the engines. Interconnection between the remote radiators is included, as is a building and engine heating system. Failures that would require the shutdown of the generation system would include loss of fluid due to pipe or valve failures in the power plant. Frequency of occurrences The fourth edition of the "District Heating Handbook," published by the International District Heating Association (IDHA), states that piping failures of hot water heating systems range from 0.048 to 0.32 per mile per year. Research provided by I.C. Moller, a district heating piping manufacturer, indicates that the failure rate for their type of installed pipe is less than one per circuit mile year. 25 The reliability analysis conducted for this project assumed a conservative rate of one failure per circuit mile year. Description and estimate of effort and material to return to full service (tasks/v1 Repair of the jacket, valves or heat exchangers is estimated to take an average of less than 8 hours once the repair person is on site. The buried district heating pipe would require from 8 hours or less to several days to repair. The longer period would apply if extensive ground thawing were required. For a difficult repair, tasks would include locating the leak with leak detectors, digging up the pipe, cutting out the damaged section, cutting a replacement piece, welding it in place, and replacing the jacket. In other cases a leak could be fixed by simply welding the defect, or using a repair sleeve, and reestablishing the jacket. For these analyses it was assumed that the time from notification to mobilization would be 24 hours, that there would be an average of a 24-hour weather delay, and that the average time for fixing a defect would be 24 hours, for a total of 72 hours. This was the value used in the analysis for the Mean Time To Repair (MTTR) a defect. Esti fd : A failure rate of 0.4 occurrences per year was calculated. An estimate of the cost of each incident, involving outside crew, would be about $400 for materials and tools, $1,000 for labor, and $600 for transportation and per diem, using commercial transportation. This adds to an total of $2,000 per incident. Since there would be only one incident per 4.3 years in this analysis, the yearly average cost approximate $800 per year. It would not be economical to rush to maintain the smaller district heating systems if a chartered aircraft were required. If the typical system displaces from $100 to $200 worth of fuel per day, chartering an expensive aircraft to save a day or two would not be warranted. Effects of system life on frequency of occurrence The system life will not be affected if the repair frequency is higher or lower. It will be affected if the repair frequency is an indicator of poor design, poor materials, or poor workmanship. It is important to the life of any system that maintenance procedures be established and adhered to. Preventive maintenance, including checking alarm systems, repairing leaks in the summer, replacing 26 gaskets, keeping records of replacements so replacement periods can be derived, is of considerable importance in assuring the long-term economic life of the project. — i inimize fail Li Some of the design decisions that will be made to assure long life and reliability are the selection of corrosion resistant materials, the use of duplex pumps, and the use of isolation valves so a failure on one leg will not necessarily shut down the entire project. Where possible, flanges will be used for valves and all the interior plant pipe will be welded to improve system reliability. Items which the reliability analysis shows are of critical importance will be duplicated if economically feasible. All connections to the district heating system are separated from the power plant by isolation valves and a heat exchanger to minimize the consequences of a failure. User building heat will not be interrupted by a failure of the main district heating system, or by the failure of another user's system. The design includes the use of "arctic" pipe which includes a steel carrier pipe with from 1 to 2 inches of insulation covered with a non-corrosive jacket. Two tin-plated copper wires are carried in the insulation to indicate the presence of moisture as an alarm. These alarm wires are read by a $1,500 alarm device which can connect to as many as four individual pipe loops. These devices allow for failures to be detected before they have time to become a major problem. They also minimize the time required to locate the failure and reduce excavation costs. This pipe will have a steel carrier pipe which will be butt-welded together. At this time we know of no failures of this piping system in Alaska. 27 Stote of Aicska om Steve Cowper @overner Alaska Energy Authority A Public Corperction TELECOPY (ANCHORAGE Telecopy Phone No. (907) 561-8584) (JUNEAU Telecopy Phone No. (907) 465-3767) TELECOPY SENT TO: re a a NAME OF COMPANY: ro <> rt COMPANY ADDRESS: Pre eta BAe TELECOPY PHONE NUMBER: ees SENDER: a ee eee a eee TELEPHONE NUMBER: 261-7 ee) CHARGE CODE: Srezesos NUMBER OF PAGES SENT: Zs INCLUDING ‘THIS COVER PAGE DATE SENT: —_8__ 145. 22. _ IF YOU DO NOT RECEIVE ALL OF THIS TELECOPY PLEASE CALL: (907) _ 262-7240-Anchorage (907) 465-3575-Juneau SPECIAL INSTRUCTIONS: = PO.

On this first report, however, it would be best to submit a copy of the final report for review before making multiple copies. Since another iteration of the draft report has been submitted, I have given it a brief review and have the following comments: 1. Put your explanation of comment 4 (re: engine heat to coolant) in the narrative portion of Appendix A. 2. Show the sizes calculated for comment 7 in the report. Put the pipe sizes on the drawings and the equipment sizes in the specs. 3. The piping arrangement of the heat exchanger, radiators, and AMOT in Figure VI-3 is unacceptable. This arrangement would reduce the heat available to about half of that calculated in Appendix A. Radiator warming may be accomplished by a one inch AMOT bypass if required. 4. Put your explanation of comment 11 in the report. polarconsult alaska, inc. ENGINEERS e SURVEYORS e ENERGY CONSULTANTS . BECEIVED Alaska Energy Authority March 6, 1990 P.O. Box 190869 MAR 7 1930 Anchorage, Alaska 99519 45 4 AUTHORITY Re: Contract AEA 2800098, Work Order 10, Koyuk Waste Heat. Dear Mr. Bulkow: Your comments of 28 Feb on the Koyuk Waste Heat Report are much appreciated and have been incorporated into the reports. Please see the following for explanation of action taken on review comments. Attached is a copy of the final Koyuk Interim Report. 2. The 13,806 gallons (heat available) listed in Appendix A is equivalent to the heat output from the boilers. This takes efficiency into account. The heat displaced listed in Appendix A is equivalent to the heat input into the boilers. The heat available (gallons of oil) has been corrected to be consistent with the heat displaced, or (14,764 / .73) = 20,225 gallons (Change from 90% to 95% heat output, See #4 below). The amount of heat lost in the distribution piping has been subtracted from this value so it will change depending on the amount of distribution piping connected to the system. 3. The Monthly Power Production figures listed are the official values submitted by AVEC to AEA for power cost equalization payment. 4. The amount of heat available off the engines listed in Table IV-B is from the engine manufacturers engine specs. The amount of heat available off the engines used in Appendix A comes from the engine manufacturers test data which they indicated was good to +/,5%. We used 95% of their test data values for use in Appendix A as the heat available off the engines. 5. Caption on figure IV-4 changed. 6. An explanation of the method of distributing the annual fuel usage is included in Appendix A, Sample calculation of washeteria fuel distribution added in the Appendix and explanation added prior to fuel distribution table on page 18. The domestic hot water is heated off the boilers. 1503 WEST 33RD STREET e SUITE 310 e ANCHORAGE, ALASKA 99503 PHONE (907) 258-2420 e TELEFAX (907) 258-2419 polarconsult 7.

The AMOT in your suggested location would be a diverter valve. In its present pm a location it serves the same function but as a mixing valve. This is per AVEC's typical arrangement. AVEC's preferred operation is to keep flow through the radiator to prevent cold shocking. Heat exchanger symbol deleted from legend. Pump used. Note 3 deleted. Piping description added in Section 02700. Title of Figure X-2 changed. The school uses all of the heat available during the winter months. The amount of heat lost from additional distribution pipes then decreases the amount of heat available. This makes the washeteria a loss to the system, if included, as the distribution line remains heated but provides no heat to the washeteria during the winter. Three sets of calculations included, one for each concept. Engine data coordinated, See comment 4. Only one copy of draft reports will be submitted in the future. Sincerely Yours Str (Jone Earle V.

Pages 1 & 39 and Appendix A also indicate that 14156 gal/yr would be saved if just the school was connected and that 15794 gal/yr would be saved if both buildings were connected. Obviously we can’t save more than is available. If these are the numbers that the program turned out then there is an error in the program. 3. As mentioned in the previous review comments, it would be better to obtain Monthly Power Production figures directly from AVEC rather than AEA. Going through AEA simply adds one more level at which errors could creep into the data. 4. Coordinate the Heat Avail. figures in Table IV-B with numbers that appear in Appendix A. 5. Change the caption of Figure IV-4 on page 12 to read: Back wall, Proposed Location of Primary Side District Heat Piping. 6. As mentioned in comment 16 of the last set of comments, clarify how the monthly Distribution of Fuel Oil Use in Table V-B was derived. Show Heating Degree Days and amount assumed to be used in heating domestic hot water. 7. Assume a 20 degree F temperature drop and the maximum BTU/HR delivered (based on the program output) to calculate preliminary sizes of the main piping, heat exchangers, and pumps so that an accurate cost estimate may be done. 8. Make the following corrections to Figure VI-3 on page 23: a. Add check valves to the engine outlets. b. Connect engine #2. c. Show isolation valves on the secondary side of the heat exchanger. d. Delete the second bypass line on the primary side of the heat exchanger. e. Using a valve to force flow through the unit heater just increases the pressure drop that the engine pumps have to pump against. Connecting the unit heater between the engine supply and return headers should provide sufficient flow through the unit heater. f. Relocate the AMOT valve so that the normal flow is from the engine through the heat exchanger to the AMOT and then either back to the engine or through the radiators depending on the amount of cooling required. The radiators loose a lot of heat even when the fans are not running and the configuration shown forces flow through the heat exchanger to pass through the radiators as well. g. If the pump and heat exchanger symbols are not used in this drawing then they should be deleted from the legend. h. Delete ‘AND UNIT HEATERS’ from note 3. 9. Describe the "Arctic" pipe in paragraph B of SECTION 02700 on page 30. (ie. steel carrier pipe with polyurethane insulation and HDPE jacket) 10. Change the title of Figure X-2 on page 40 to read: Gallons of Heating Oil Displaced. 11. Correct the problem in the program used in Appendix A that is made evident by Figure xX-2. It is improbable that the school alone would recover more heat than both buildings together as is indicated for the months of January, February, March, and December. 12. Rather than combining the three computer runs please provide three sets of calculations in Appendix A: one for the school alone, one for the washeteria alone, and one for both facilities being connected. 13. Coordinate the generator data in Appendix A with Table IV-A. Table IV-A indicates that the Cummins LTA 10 only rejects 1937 (BTU/HR)/(KWH) to the coolant at full load and is only rated at 175 kw so it should never see loads as high as 187 kw. 14.

This should be a concise synopsis of the report. Currently it is disjoint and filled with grammatical errors. (Grammatically, the rest of the report is mostly OK. It’s the one page that everyone will read that is in such poor shape.) 2. Present the results in the Executive Summary in the same manner as the sample provided earlier. Indicate the estimated project cost of the most economical alternative, the annual fuel savings for that alternative, and the equivalent dollar value of the fuel savings. 3. We will not be charging AVEC to heat their building with their own waste heat. The energy used to heat the powerhouse should appear as a system loss in the calculations and nowhere else in the report. 4. Exhaust stack boilers are high maintenance items and should not be used in any of these smaller sites. You may wish to mention them in passing in the Failure Analysis section but delete all other references to them in the report. 5. Combine all the concept drawings (pages 5, 7, 13, 14, etc.) into a single section rather than having them scattered throughout the report. 6. On page 5, label the two different piping runs as concept 1 and concept 2. 7. On page 7, identify the equipment shown and show roughly how the heat exchangers are connected to the power plant cooling piping and the end use building heating piping. 8. On page 7, locate the circulating pump for the arctic piping loop in the end use building rather than the district heat module. 9. Provide borders on all concept drawings. 10. It would be better to obtain Monthly Power Production figures directly from AVEC rather than AEA. Going through AEA simply adds one more level at which errors could creep into the data. 11. Provide unit heaters for the powerhouse rather than just taps for unit heaters to be connected. 12. Some of the power plant waste heat recovery equipment appears on page 13 and some appears on page 14. It would be best to show only the assumed configuration of the power plant before adding the waste heat system on page 13 and the entire new configuration on page 14. 13. On page 13, relocate the circulating pump for the arctic piping as indicated in comment #8. 14. Simplify the piping on page 14. Use a single AMOT valve and show check valves on the engine outlets, flex connections to the engines, unit heater for building, and connection to engine #2. 15. Provide the information shown on page 16 in the form of two graphs in the conclusions section of the report as per the samples provided earlier. 16. Indicate how the distributions of the monthly fuel oil use figures were derived on pages 20 & 25. If they are based on local heating degree days then show the heating degree days for each month in the tables and mention this method in the text. 17. Clarify what is meant by ’Remote Buildings’ in Table VI- A-3-2. Does this include the high school domestic hot water and the gym forced air furnace? 18. Restrict the references to the amount of fuel oil saved to the conclusions and the summary. Delete the references to fuel oil displaced on pages 20 & 25. 19. Indicate where the yearly fuel consumption figure for the washeteria (on page 25) came from. 20. On page 29, indicate the publication dates of the codes that apply and state that they were followed in preparing this report. 21. Provide a narrative description of how the calculations were performed in Appendix A. 22. Provide three sets of calculations in Appendix A: one for the school alone, one for the washeteria alone, and one for both facilities being connected. 23. As mentioned in comment #3, move the power plant heating to the System Loss side of the calculations in Appendix A. 24. Indicate which engine the Generator Data heat rate figures are based on in Appendix A. The numbers shown do not seem to match up with any of the figures provided on page 8. 25. Include a list of contacts and their phone numbers in Appendix B. 26. Do not include Appendix C in this report. If you already have write-ups of the AVEC system plans for each site then compile them into a for-information-only booklet. 27. The above comments do not address many of the instances of poor wording and extraneous comments within the report. Please send someone by to pick up a marked up copy of the report that shows most of these. polarconsult alaska, LETTE OF TRANSMITTAL 1503 West 33rd Avenue e Suite 310 ANCHORAGE, ALASKA 99503 (907) 258-2420 FAX (907) 258-2419 a= DATE Z-\4-90 ATTENTION to Atnsun Enezay AvtHoeite toms Bure wt Detect Hear Spies, 7 Vinayes WE ARE SENDING YOU eAttached (] Under separate cover via___________the following items: 1) Shop drawings C Prints [) Plans 1 Samples OC Specifications 7 Copy of letter 1 Change order YK Kegon _ copies | _ DATE ] NO DESCRIPTION _ Bm Z-\W\-% INTE REepeeT , Korue Drotucr tear Concept Vesian THESE ARE TRANSMITTED as checked below: CI For approval (J Approved as submitted LC) Resubmit copies for approval For your use C Approved as noted C Submit copies for distribution As requested (] Returned for corrections ( Return corrected prints C) For review and comment [1] EE) ORR BUDS WE as (] PRINTS RETURNED AFTER LOAN TO US REMARKS THe, KevoeyT Rermaces athe Zeenes sueriqep 2-\-90.

Waste Heat 9 Villages Atm: Mr. Gary Smith Project Manager Dear Mr. Smith: This proposal is made in response the scope of work you provided us for doing Concept Level Designs on nine western Alaska AVEC villages. This proposal contains a Lotus spread sheet which shows the work items and their associated fees and expenses. Included is a proposed fee for HMS's estimating work. This proposal is based on supplying a concept level design in accordance with the work items as listed in the general work tasks and the individual designs. Travel is based on a site trip to each village by local carrier then by charter back to a central location, which will be Kotzebue, Nome or Bethel in the afternoon. If this charter can be avoided, the local mail carrier will be used. As you can see by the enclosed sheets from Quality Travel this may be possible in some situations. We will use this potential cost savings in travel for our weather allowance. We will amempt to work if we are held up by weather, If we can use our time productively there will be no standby. We have planned on two people traveling to all of the villages with the exception of the first two kick off locations. These personne! will be the future designers who will provide the asbuilt information and get the data necessary for design. We will attempt to acquire information on land status so we can locate the pipelines in the most advantageous position, avoiding existing utilities and reducing to the extent feasible, problems with land acquisition. It is important to note: that we will get what records we can within the time available. We can not guarantee thar the land records will be complete or accurate. Only a detailed more time consuming analysis with title searches by Tom Arminsky will accomplish this. 1503 WEST 33RD STREET # SUITE 310 ¢ ANCHORAGE, ALASKA 99503 PHONE (907) 258-2420 « TELEFAX (907) 258-2419 DEC @6 '89 15:14 FSOLARCONSULT 2s7 Fad WASTE HEAT CONCEPT DESIGN PROPOSAL DATA YEAR 1990 dite loerim Final Fee = Expenses Report Repon. 1.

Box 15 Koyuk, Alaska 99753 Re: Waste heat availability. Dear Fred: In answer to your question regarding the use of waste heat for your church, I would like to relate the following information. The Alaska Energy Authority has provided management services either directly or through consultants for the development of waste heat recovery systems involving AVEC Power Plants at Kiana, Ambler, Shungnak, Savoonga, Elim, Kaltag, Grayling, Goodnews Bay, Togiak and New Stuyahok. With the exception of the Togiak and New Stuyahok systems, funding for the projects was obtained through the state in the form of grant funds. In the case of the Togiak and New Stuyahok systems, funding came from the Southwest Regional School District. The City of Shaktoolik and the City of Emmonak, both used state grand funds to hire a consultant and install a waste heat recovery system in their communities. In St. Michael, the Public Health Service hired a consultant to manage the installation of the system. All of the systems installed in AVEC Villages with the exception of the Emmonak, Shaktoolik and St. Michael systems provide heat to the schools. Some of these systems also provide heat to the water plants. The systems at Emmonak, Shaktoolik and St. Michael provide heat only to the water systems. The cost of installing the systems vary depending upon such factors “as the distance between the power plant and the end user and the configuration at the power plant such as whether the plant is already equipped with remote radiators or whether each engine still utilizes their skid mounted radiator. In your situation funding will undoubtedly be the most difficult problem to overcome in order to provide waste heat to your church. It is doubtful whether the heat load of the church would justify the expense of a full scale system to serve only the church. However, one approach might be to propose a system that would distribute heat to both the school and the church. Another approach might be to install a very small scale loop to the church only, similar to the system installed at St. Michael. However, even a project of this small scale would have a cost likely exceeding $10,000. Funding would be required to cover the cost of the initial design and then the actual materials and installation. Since AVEC does not have funding available for this type of project, I would recommend that a formal request be made to the Alaska Energy Authority to assess the feasiblity of capturing and transferring heat to the church and to develop a rough budget for completing the installation. If the AEA does not have funding available to complete the project then the budgetary information could be used to request grant funds. The only other alternative would be to hire a consultant directly, however, I would recommend that you contact the Alaska Energy Authority first, since they may be very willing to provide this service to your community. ye ¢ Me Mark Teitzel Assistant General Manager cco:;, Steven Stassel, AEA State of Alaska Steve Cowper, Governor Alaska Energy Authority A Public Corporation November 6, 1990 The Honorable Frank Kavairlook, Sr. City of Koyuk P.O.

One 268 KW 1800 RPM Generator may not be needed as it has been recommended that the AC 685I engine at Savoonga be relocated to a village where an existing AC 685I is due for an overhaul. One 268 KW 1800 RPM Generator became available following the decision to convert the Old Harbor module unit to 1200 RPM. It is still recommended that a spare 268 KW three phase 1800 RPM generator be kept in stock as a backup unit for Ambler, Elim, Goodnews Bay, Grayling, Holy Cross, Huslia, Kaltag, Kivalina, Koyuk, Marshall, Mekoryuk, Minto, New Stuyahok, Noatak, Old Harbor, Pilot Station, Quinhagak, Russian Mission, Scammon Bay, Shaktoolik, Shungnak, St. Michael, Stebbins, Toksook Bay, and Tununak. 5. We currently do not have a spare KTA 1150 engine in stock to back up the existing KTA 1150s at Alakanuk, Gambell, Nulato, Pilot Station, Quinhagak, Savoonga, Shishmaref, and the future units at Ambler, Noatak, and Toksook Bay. -. “Secember 7, 1988 88-M-363 Page 3 i Final Summary Recommended for Purchase One Cummins KTA 38 1200 RPM Generator Set (850 H.P.)

Box 190869 Anchorage, Alaska 99519-0869 SUBJECT: AVEC Projects for System Efficiency Improvements Dear Brent: According to our recent telephone conversation, attached is a copy of the list recently sent to Senator Hensley on a variety of capital project which would be useful in AVEC villages. Many of these are related to energy effi- ciency improvement and are self-explanatory. As you can see, there are numerous places where we can use money for upgradings. We could compile some statistical information about what these improvements can do since we have similar installa- tions in other villages. If after reviewing this, you wish to have more details on any projects, we would be pleased to work with you in this regard. Best Regards, yd M. Hodson General Manager XC Dem Sit vere. CG.

Ib. be dee Vete~ EFFICIENCY, RELIABILITY, AND SAFETY IMPROVEMENTS TO THE VILLAGE ELECTRICAL POWER SYSTEMS OBJECTIVES: Each AVEC power plant would be equipped with waste heat recovery equipment capable of capturing a portion of the heat rejected to the engine coolant and transferring that heat to an end user such as the school, water plant, or city for use in decreasing oi] requirements for space heating. Each AVEC power plant providing peak loads in excess of 175 KW would be equipped with two all-steel, fireproof, long-life generator modules. Each AVEC power plant would be equipped with two of the latest design diesel electric sets featuring peak fuel efficiency. Each AVEC power plant providing peak loads up to 175 KW would be equipped with all-steel, fireproof, long-life generator modules. Each AVEC power plant would be equipped with an insulated, all-steel, fireproof, long-life control module for housing the control equipment in a protected weatherproof area. Each AVEC power plant would be equipped with three control panels capable of providing complete control and protection of each diesel engine and generator. Each AVEC power plant would be equipped with a waste oil blender which would filter waste lubricating oi] and blend it into the normal engine fuel supply to be burned off by the engine. Each AVEC fuel tank farm would be installed on top of an impermeable barrier which would prevent the escape of any leaked or spilled fuel. Each AVEC power plant would have a chain link fence installed around both the power plant and the fuel tank farm to keep children and unauthorized individuals away. Each AVEC distribution system would be converted to an overhead pole supported system having higher reliability and lower losses.

Beans President Alaska Village Electric Co-operative, Inc., Board of Directors 4831 Eagle Street Anchorage, AK 99503 Dear Mr. Beans: I have received your correspondence of January 31 regarding the capital project request by the Alaska Village Electric Co-operative. Thank you for informing me of your organiza- tion's support of the twelve programs to convert village electrical systems to overhead distribution. As you may be aware, I had proposed a Fiscal Year 1986 operating and capital budget for the State of Alaska total- ing $2.97 billion in general funds. With declining oil prices reducing our projected revenue, we will not know with certainty what amount will be available for the capital budget until we receive our March revenue forecast. We do know, however, that the total capital budget will be far less than it has been in recent years. Funding for the projects requests you have submitted has not been included in the proposed budget. In order for the projects to receive consideration throughout the budget process, it is important that the communities submit them as community priorities. I encourage those communities that rate the system conversion project as a top priority to work closely with their legislative delegation, as well as with the appropriate State agencies. You may be assured that all projects included in the final FY 86 budget presented to me by the Legislature will receive full consideration. I have referred a copy of your letter to the Office of Management and Budget, as well as to the Alaska Power Authority, for their information and review. XC’. Ed Moms Sandan Whe Mr. Vincent T.

ALASKA 99503 TELEPHONE: (907) 561-1818 January 31, 1985 Mr. Bill Sheffield, Governor Office of the Governor Pouch A Sie ams SAS EAE Eee ey Juneau, Alaska 99811 : Walaa Dear Governor Sheffield: Alaska Village Electric Cooperative serves 48 cities across Alaska with a total population in excess of 15,000. AVEC provides electric service to a majority of communities in Western Alaska with populations from 125 to 800 citizens. The Cooperative has in the past received the large majority of Cooperative money for construction of generation and distribution facilities from REA in the form of loans. This adds an element of interest cost to our KWH retail rates. In addition, the loan funds must be repaid. Many villages and cities have received numerous grants, sometimes ranging into the millions of dollars, for electrical facilities. AVEC originally constructed distribution systems with underground and later surface utilidor in some areas. While well intentioned at the time with funds available, both types of systems have proven to have reliability or maintainabil- ity limitations in the arctic environment. Damage due to ground cracks and frost heaving action causes safety problems to develop. Accordingly, AVEC has been subject to some criticism from regulatory agencies as a result of practical problems associated with providing service in remote village areas, necessitating accelerated conversion action to reduce future problems. Many consumer service entrances were also found to be substandard by investigators and subjects the village consumers served by regulated utilities to immediate disconnection under ene rigid interpretation of statutes/regulations by State agencies in small villages. The Cooperative has started a program to convert to overhead distribution to improve safety and reliability. The cost to complete this is estimated to be some $15,000,000 in current dollars. We therefore request that AVEC receive a grant to the Cooperative in the amount of $3,890,000 in the new state budget as a first installment on this project with similar annual increments each future year until this task is satisfactorily completed. Included in the list of conversion projects scheduled with the first installment are as follows: Mr. Bill Sheffield, Governor January 31, 1985 State of Alaska Page Two of Two Estimated City/Village Cost Shishmaref $454,000 Selawik 630,000 Scammon Bay 258,000 St. Mary's 2nd Phase, St. Mary's Airport Line, 506 ,000 Pitkas Point Intertie, Pitkas Point Stebbins 263,000 Holy Cross 2nd Phase 263,000 Alakanuk 2nd Phase 188 ,000 Marshal] 109,000 Noatak 300 ,000 Koyuk 245,000 Elim 264,000 St. Michael 410,000 Total $3,890,000 This project will provide long range benefits to the village people in many communities with more reliable and longer life electrical facilities. Accordingly, the Board of Directors of Alaska Village Electric Cooperative unanimously forward this request and encourage the strongest support of the Administration and our elected officials to ensure this receives high priority and adequate funding.
