As you men- tioned during the visit, the fuel economy of the power plant seemed to be lower than expected and the newly installed totalizing meter seemed to indicate that excessive line losses were to blame. However, aS outlined in the following, line losses may be only part of the problem; unmetered loads and meter problems may be the real prob- lem. We identified the following unmetered loads:, 1. The Shop: - ~ The 23 incandescent lights in the shop are each rated at 150 watts and © the 4 fluorescent fixtures in the snowmachine shop each consume approxi- mately 95 watts. With the estimated average burn time of 16 hours per day, this corresponds to an average monthly consumption of 1,864 kwh. 2. The Street Lights: It is estimated that your 21 street lights are operated an average of 12 hours per day and that they each consume 205 watts. That corresponds to an average monthly consumption of 3,143 kwh. 3. The Station Service Power: If we assume that the 1,500 watt block heater on the Caterpillar is operated 80% of the time, this gives an average monthly consumption for this component alone of 876 kwh. If we assume that the 4 light fixtures in the power plant are operated continuously, this adds another 277 kwh per month. If we assume that one exhaust fan and one radiator/unit heater fan is operating continuously, this adds another 329 kwh per month for a total power plant consumption of 1,482 kwh per month. A review of your billing records indicated that the high school was using an average of approximately 1,000 kwh per month. This is quite low for a high school and a subsequent inspection of the meter Q_ PO.

According to your records, the school district had supplied a meter multiplier of 10, where the current transformers in the meter carry a rating of 400:5, which gives a meter multiplier of 80. In other words, all billings based on the multiplier of 10 have been grossly in error and have covered only 12.5% of the actual consumption. As an average, it appears that this meter error accounts for approximately 7,000 kwh per month. ; , \ ' ' i ' Reviewing these identified non-metered (or' inaccurately metered) loads, | it appears that a total.of 13,489 kwh per month can be accounted for this way. Out of this figure everything except the station service loads should have. been billed to the City or the school district. In order to illustrate the significance of these loads, I tried to add these loads to the sales reported for the fiscal year of 1988. This increased the number of kilowatthours sold during fiscal year 1988 to 391,467 kwh from the 247,383 kwh reported to the PCE program. This would have increased the number of kilowatthours sold per gallon consumed to 9.43. from the reported 5.96. Please note that this is based on a number of estimates and assumptions and that actual figures may be significantly different. However, it does indeed show that your : + --___--—- generation/distribution_system.may_not_be_nearly as_bad-as_feared_and_—______ you may-not have any difficulties meeting the new standards for fuel efficiency as proposed by the Public Utilities Commission. In order to determine the actual line losses and thus the real need for a distribution system upgrade, I suggest that that following steps are taken:> 7 : 1, The Shop and Power Plant: Install a separate meter for the shop including the snowmachine shop and invoice the City each month in accordance with the meter reading. Also, install a separate meter, which will measure the power usage in the power plant (including the stand-by module). I am aware of your efforts in connection with the installation of a separate transformer for the generator room, which is incorporated into the shop area. Please be aware that unless the entire building is supplied with power through this transformer, there is a potential for a code violation in this installation. The National Electric Safety Code restricts the number of "service drops" on a building for safety reasons, and unless certain conditions are met, only one drop is allowed. If the entire building is supplied through one transformer, this should not be a problem; two meters should then be installed "downstream" from. the transformer with one meter being for the generator room only and the other meter being for the shop. 4621/923/2 Mite VNULN LoeWwI>d December 22, 19°° Page 3 2. Street Lights: Install a meter on one street light and invoice the City for the total consumption, which is calculated by multiplying the number of street lights with the metered consumption for one light. 3. The high school Immediately notify the Bering Straits School District of our findings concerning the correct meter multiplier and on all future billings utilize the:correct multiplier of 80. I would also recommend that you } notify the Alaska Power Authority's Power Cost Equalization Program of the findings so that they can re-calculate your PCE- reimbursement immediately. Your PCE- rate is likely to be decreased slightly, since your sales will increase without any r Anctehtas in operating costs. In order to avoid a. future rate-shock and possible repayments to the PCE program, I believe that it will be in your interest to take care of this issue immediately. Needless to say, the increased sales to the school district will more than compensate for the reduced PCE-rate. At this point I do not have enough information about the potential for recapturing the lost revenue from the school district to be able to offer any advice .on this subject. However, I would notify the school district that you. reserve the right to recapture your lost revenue with interest back to the date, on which the school's meter was installed. — If you have any questions or if there is anything else, I can do for you, please do not hesitate to contact me.

SUBJECT: Trip Report - Rural Systems Efficiency Program Golovin & Buckland DATE: December 15, 1988 On December 12 Peter Hansen and I traveled to Golovin to present information on the Rural Systems Efficiency Program to Mayor Tom Punguk and city council members. Energy audits were completed on three community buildings: the airport warm up building, the city office and the shop/equipment storage building. The City is also interested in a residential lighting program, so we discussed survey forms used in the Nikolai project. Peter worked with power plant operator Chuck Lewis on the City’s concerns with its current distribution system. The City believes voltage is inadequate for present load and the planned addition of a new housing subdivision this spring. The City noted they had sent the Power Authority a letter request- ing technical assistance on their distribution line problems. The same letter also was to note their interest in the Rural Systems Efficiency Program. To date, we have not seen a copy of this letter. I plan to evaluate information obtained from the energy audits and make recommendations as to specific projects in Golovin. The City has trained workers, and would like to do a grant agreement with the Power Authority, rather than having an outside party perform the work. After spending the day in Golovin, we traveled to Nome. Peter returned to Anchorage on December 13, and I continued on to Kotzebue and Buckland, arriving in the late afternoon of the 13th. Tuesday afternoon was spent discussing program specifics with City Administrator, Darlene Hadley. That evening I did an energy audit on the health clinic, and the next day energy audits on the city maintenance building, the snow machine repair shop and the old city clinic (currently used as a recreation facility). The city requested assistance on internal wiring problems in about 17 homes, and I told the City Administra- tor that our program did not really cover that, but I would "dis- cuss it with our staff." The City is interested in a residential lighting program, so I left a sample bulb and a handout on the Rural Systems Efficiency Program for Darlene to distribute at the upcoming council meeting on January 10. The City wishes to participate on this project through a grant agreement, although they would hire an energy service company to supervise the work. I returned to Anchorage on the evening of December 14. Our contract may be handled through an amendment to the current agreement, or a separate agreement specificially for work on this project. I plan to have something ready for the January council meeting to avoid a month-long delay in community approval. Energy audits on the community buildings in Buckland will be prepared separately to provide a basis for deciding on the types of improvements that should be accomplished.

The Golovin Power Utilities had thought over the years of operation that our operations were losing power through the system through line losses somewhere in the system but after analyzing the problem,the main problem was found to be unmetered usage by the city and incorrect metering to the M.L.OLSON high school complex. It was found that the metering system to the school was giving erroneous readings through the multiplier on the meter,as explained in the enclosed letter. Please review the letter and I hope we can come to a consencus of what must be done about any past due account due the Golovin Power " utilities. The Alaska Power Authority will be contacting us soon with recommendations on what we can do so that all accounts can be cleared up--with-the-district.—We-now-realize-that-the-problem-has—existed since the Golovin Power Utilities began supplying power to the school complex and the erroneous readings were no fault of the City and possibly was just an oversight that was not notice by the maintenance department of the school district. We are n@t trying to place blame on anyone: but wish to settle the matter with the best interest of both parties concerned and.the best interest of all customers served. The Golovin Power Utilities is a wholly owned and operated entity of the .City of Golovin and ask that this problem be resolved as soon as possible in the best interests of all its customers. The School Districts soonest consideration in this matter would greatly benefit all our customers as we feel that operating and maintenance costs should be borne by all customers according to their utilization of the services provided. : fe.
