Parties Bearing Risk IP/City/RP/AEA/M/B City/RP/IP/AEA/M/B AMOR 10/OESI/AEA/City/IP/RP City/RP/IP Unalaska Geothermal Project Jack Templeton's Report -November 26,1991 The Alaska Energy Authority (AEA)is considering the feasibility of constructing a geothermal energy plant with the proceeds of a $67,000,000 bond sale to be repaid over 30 years. The plant would be complete in April 1994 and would provide a base annual power capacity of 88,000,000 kWh for the community.Peak power requirements would be provided by current generating equipment (diesel).In addition, businesses which generate their own electricity would be required to agree to purchase a base amount of power from the City and in effect become customers of the city's electric utility. A 17 year (through 2010)operating summary of cost of power is attached.Based on negotiations still in progress,it appears the lowest price of power,assuming the geothermal plant operates at full capacity,would not be less than 15 cents per kWh.The level of power purchased from AEA directly affects rates charged to customers as the AEA is required to charge rates to pay for debt service and operations.Accordingly,stability in the Unalaska/Dutch Harbor economy for the next 30 years is extremely important. The 17 year operating summary details rates which would need to be charged at varying economic activity were the economy not to be stable. Lastly,looking from a debt standpoint,our most recent audited financial statements show a total of $18,192,974 of loans,revenue bonds,and general obligation bonds outstanding at June 30,1991.On completion of the dock project,this total will become $22,000,000 (or $6,377 per capita).AEA's $67,000,000 of bonds would not be reflectedintheCity's financial statements (or per _capitacalculations)but the obligation to repay those bonds through increased electric rates,should the geothermal field become unproductive,would remain.Whether this would affect our ability to obtain additional bonds in the future is not known.

Analysis of Loads and Resources P,02 December 6,1991 The purpose of this memorandum is to summarize the results of our analyses Area Loads There are three categories of area loads which we have examined.The "City -Existing"load is the existing load served by the City's diesel generators."ProcessorLoads"are the loads of the three major seafood processors-Alyeska Seafoods,UniSea and Westward Seafoods.These processor loads are all currently served by the processors'own generation."Prospective Loads"are major loads which either exist or are anticipatedtodevelop,but are not currently served by City generation,The following tablesummarizesarealoadswhichwehaveforecastedfortheyear1994: Area Loads -1994 (kWh/year) City -Existing Processor Loads: Alyeska UniSea Westward Total Processor Loads Prospective Loads: APL Os!

The City's existing load is based upon the 1991 load level,increasedby5%per year to 1994.Some load growth in the City's existing loadisanticipatedoverthenextthreeyearstoreflectthefactthatinfrastructuredevelopmenthaslaggedsomewhatbehindthegrowth in the fishing and fish processing activities.Thus,there will be somecatch-up causing growth in existing City loads over the next few years. With respect to processor loads,the Alyeska load is based upon the1991loadlevels,assuming no load growth.The UniSea load is based upon 1991 load levels,annualized to reflect a full year of operationofthenewUniSeapowerplantandfishprocessingfacilities.The Westward Seafoods load is based on 1991 load levels,annualized to reflect a full year of operation and a growth factor of 25%.Westward has indicated that some additional facilities are planned to be constructed within the next year or two,and that full operation of the plant would be at a somewhat higher level than indicated by thefirstpartialyearofoperation. The prospective loads of APL (American President Lines),OSI (Offshore Systems,Inc.),SeaLand,and Icicle Seafoods are all existing facilities but are supplied by self-generation. The estimate of load for the Margaret Bay developmentis very rough at this point.Limited information is available.A 106-unit hotelcomplexisthefirstexpecteddevelopmentandisplannedforcompletionin1992.Additional development of retail space,warehouse space,cold storage space is planned within the next threeyears.We have been told that UniSea will own the hotel,andthereforeitisuncertainwhetherthisloadwillbeservedbythe UniSea power plant or by the City.The attached memorandum fromMikeHubbardprovidesmoreinformationontheMargaretBaydevelopment.os UGV-9-91 HUN 14604 RW DEUA/OCH!ILE GUNDULI rAA NU,ZUG 441 4¥b64 P,U4 Memorandum to: .File -3-December 6,1991 Use of Resources In order to determine the use of resources in meeting the area loads,we have used an hourly dispatch model called ProSym.We ran two cases,one without the prospectiveloadsandonewiththeprospectiveloads.The following table summarizes the results of the two load and resource analyses: Case No.1 Case No.2 w/oProspectiveLoads with Prospective Loads(kWh/year)(kWh/year) City Loads and Resources: City Loads -Existing 23,535,000 23,540,000 Prospective -22,300,000 Alyeska 8,588,000 8,589,000 UniSea 19,685,000 19,687,000 Westward 8,980,000 8,981,000 Total 60,788,000 83,097,000 City Resources -Geothermal 60,788,000 80,290,000 Diesel 0 2,807,000Total60,788,000 83,097,000 Processor Loads and Resources - Alyeska: City Purchase 8,588,000 8,589,000 Diesel 4,558,000 4,558,000 Total 13,146,000 13,147,000 UniSea: City Purchase 19,685,000 19,687,000 Diesel 10,888,000 10,888,000 Total 30,573,000 30,575,000 Westward: City Purchase 8,980,000 .8,981,000 Diesel 6,794,000 6,794,000 Total 15,774,000 15,775,000 e ! --DaG-3-91 MON 14°05 RW BECK/SEATTLE CONSULT FAX NO,206 441 4964 P,05 Memorandum to: File -4-Deveanber 6,1991 With respect to the above table,it can be scen that the energy used from the geothermal resource is approximately 60 million kilowatt-hours por year without therospecuveloads,and approximately /y kiiowan-hours per year with the prospectiveoads.(The prospective load cannot be included in the load projection unless there are arrangements in place for the City to serve the prospective loads.)The model shows asmallamountofuseofCitydieselsinCaseNo.2,This use of diesels in Case No.2 istomeetpeakingrequirementsduringcertaintimesoftheyear.

Permitting is currently the most critical area to maintain the new schedule.Another field trip will be required to perform a number of duties,including some that were not able to be accomplished during the last reconnaissance because of high snow levels. Engineering for road design will be delayed commensurate with the revised road construction schedule.This engineering will be awarded in the May -June time frame depending on the progress offinancialclosing. Page 1 DTESCUSSTON PERMITTING Preliminary engineering of the road,bridges and pier has been completed by Peratrovich and Power Engineers,and forwarded to Dames &Moore for preparation of the permit applications. The permitting process has been slow for a variety of reasons, including the inability to obtain accurate field data because of high snow levels in the valley.The permit applications are expected to be completed and submitted by April 1.This will allow 90 days for the permit review and approval process. Another field trip is required as soon as the snow levels drop.This trip will be used to perform a fish assessment for the new road alignment,complete a side stream assessment, survey the bridge crossings,and survey the title lands.This work will be performed at the earliest date possible as it is required to support the final permit. ENGINEERING PN&D has completed their seismic testing and boring along the road alignment.The information included in this report will be invaluable when detailed engineering begins.The results indicate there is adequate material in these borrow sources to construct the road on the valley floor.One major borrow source is located adjacent to a Native Allotment.A temporary access permit is available from the Bureau of Indian Affairs. This permit is being pursued to allow use of this borrow source and to allow barge beach landing at that location for unloading construction equipment. Since the commencement of road construction has been moved to October 1,1992,engineering for same will not be released until approximately May or June,depending upon the progress of financial closing.Proposals for engineering the road, bridges and pier have been received.A third proposal has been solicited since one firm elected not to bid. Broad Bay has been eliminated as a port location for three reasons.Extensive discussions with the residents,fishermen, and Harbor Master suggest that during the four or five winter months this bay will be inaccessible 50%of the time. Secondly,the ocean bottom survey suggests that a Broad Bay pier would be nearly twice as long as a pier in Nanteeken Bay. Lastly,there is evidence that Broad Bay Beach has eroded approximately 50 feet in four years. Page 2 Proposals are being solicited for preliminary electrical engineering adequate to allow preparation of specification for long lead time items. PROCUREMENT With the revised schedule,an April 1,1992 order date for the OEC's is required.An order for the main power transformer and other substation equipment will be required in the next few weeks to support the schedule. CONSTRUCTION N/A RESOURCES The revised schedule will require that all wells be drilled in 1993.There will not be adequate time in '92 to pioneer a road to the South Plateau and drill a production well.This will provide a drilling program with more continuity,but the last well will not be completed until approximately November 1,1993.Therefore,drilling and testing activi- ties will be occurring late in the plant construction period. A drilling plan was developed and additional drilling contractor input has been received.However,further planning is necessary to assure that an integrated logistics plan, incorporating all construction activities,is in place. Please see item #7 below for a further discussion. START-UP,CHECK-OUT AND TESTING N/A LOGISTICS An Integrated Logistics Plan is being developed to assure that movement of people and equipment for all aspects of construc- tion has been considered.The purpose of this plan is not only to prepare for all such movement,but to assure it is done in the most cost-effective manner possible.

POWER ENGINEERS DAMES &MOORE INC,OESI 7 MW GROSS 7.3 MW GROSS 15 MW GROSS ITEM 1987 1987 1992-93 POWER PLANT Direct Costs $17,241,000 $10,881,000 $30,642,000 WELL PLANNING Direct Costs 4,128,000 2,840,000 7,061,000 TRANSMISSION LINE Direct Costs 5,655,000 3,619,000 4,596,000 ROADS &DOCKS Direct Costs 5,023,000 4,590,000 5,109,000 MOBILIZATION LOGISTICS 2,393,000 2,294,000 3,500,000 OTHER DIRECT COSTS 225,000 225,000 1,834,000 ENGINEERING,CONSTRUCTION MANAGEMENT AND INDIRECT COSTS 15,505,000 10,869,000 14,200,000 In comparing the costs,the following should be noted: 1.If the total costs in the 1987 cases are escalated at 4.5%per year to the 1992-93 time frame, these costs become: A.Dames &Moore -7 MW Gross L2e $49,120,000 x 42:25 B.Power Engineers,Inc.-7.3 MW Gross $35,180,000 x 1.25 Cc.OESI Power Corporation -15 MW Gross $61,400,000 $43,875,000 $66,942,000 It should be noted that the OESI case contains twice as many wells and is based on the experience of the OESI staff.In the Dames &Moore case,the Mesquite Group did,in fact,estimate the equivalent of $6 million for well drilling in 1992 for the 7 MW case. The double flash plant proposed by Power Engineers is not suitable for the application in this project due to the use of water cooling and the complexity of the process.The Dames &Moore plant is comparable to the OESI proposal. The "Other Direct"in the OESI case includes the upgrading of the City distribution system and a greater complement of spares. In the final analysis,OESI is proposing a plant which produces more than twice the previously |proposed power levels for:(i)10%more in cost (Dames &Moore case);or (ii)54%more in cost (Power Engineers case).

Jim Seagraves R.W.Beck &Associates Win Peterson To:Charlie Bussel]Date:October 30,1991 Executive Director -oY ,From:Dick Emerman wW Subject:Note on OESISeniorrememny I received a cal]today from Ray Benish at R.W.Beck,who felt he shouldsharewithussomeinformationherecentlyheardfromBeck's Denver office regarding OESI.He said he felt obligated to pass these concernsalongtoussinceAEAisBeck's client.He mentioned three things: 1)Soda Lake is an existing geothermal project built by OESI and financed by Prudential Power.Apparently,Prudential now considers OESI to be in default on its loan obligations.R.W. Beck was the consulting engineer hired by Prudential for the project,and Geothermex was the resource consultant that rendered its judgment that the geothermal resource was adequate.AccordingtoBenish,the power plant has been built and numerous wells drilled,but for one reason or another the resource is not proving adequate for the plant requirements.Prudential wants to get out of the project. 2)Apparently,OESI has not paid for R.W.Beck invoices on Soda Lake dating from December of last year.Benish said nothing more aboutit,but wondered if there was a liquidity problem at OESI especially in view of the Soda Lake situation and the possibility that OESI may be trying to buy out Prudential's share.All speculation.However,if there is a liquidity problem,it could affect not only OESI's plans to finance the Unalaska wellfield with OESI equity,but might affect OESI's agreement to compensate AEA for costs we are presently incurring. 3)Our present agreement calls for OESI to provide Beck with engineering drawings and specifications for the proposed Unalaska plant.Evidently,what Beck is actually receiving are faxed drawings one page at a time rather than a complete set of clean documents.Maybe this is adequate and expected,but it might also raise a question about the adequacy of OESI's resources. Benish felt that,while these items may not indicate any significant problem with OESI and their ability to perform,they are the sort of thing we would want to consider and check out as part of a "due diligence"review. I asked him for a name and number at Prudential Power,and he providedthefollowing:Elizabeth Schulz (201)802-4935.He asked that we notmentionR.W.Beck if we choose to call Prudential,because Prudential might not appreciate hearing that Beck had advertised their troubles.I told him that I didn't see why we would have to mention Beck's name,and that Brent Petrie would probably make the call. cc:Brent Petrie wet eer ww bine vu oervuct &@ GUO OCcM oc re)HtH rP.UL PANAFAX TRANSMISSION COVER SHEET PLEASE DELIVER TO:Brent Ve tne.

The geothermally generated power plant will be owned by the Authority and the geothermal power is to be sold to the City,which will supply power to the industrial users.We have prepared the attached Draft Power Sales Agreement between industrial entities and the City of Unalaska,and would appreciate your Tecammendations regarding how the contractual arrangements may be further structured to best meet your needs,as well as thoss of the City and the Authority. Our objectives include providing you and other Unalaska industrial power users with a number of advantages over the long term.These advantages include: 1.Long-term protection of users of electrical energy at Unalaska from the increases in fuel costs that will inevitably occur in the future.The cost of power from the project should increase only by inflation of that fraction of the total costs that relate to operation,The fuel for this power generation does not increase in cost as a function of the world price of oil. 2.Long-term protection of energy users from the Increase in cost of generation that is occurring due to costly increases in requirements for emission control equipment for diesel generation,These requirements may very likely be retroactively enforced.Recent experience,wherein the cost of a new generation unit was more than doubled by the addition of necessary emission control gear, causes great concern regarding this factor's effect on the future costs of self-generated power at Unalaska and elsewhere. 3.The provision to Unalaska's industrial power users of the important and valuable opportunity to become connected to an island-wide power grid.The establishment of such a grid should provide DENI DT*AGFOX LeieCOPLer FST FIUTIOTYT F115 Z29AM 5 70235691259 AK ENERGY AUTHORITY;#5 October 16,1991 Page 2 maximum possible assurance against loss of generation during times when such loss would be extremely costly to a processor.In addition,this grid may allow you to achieve significantly longer useful lives from your generation equipment than would be possible if they continue to operate totally isolated. 4,The creation for participating industrial users of opportunities to market surplus power into the total Unalaska electrical system,and thereby further contribute to the potential minimization of your total cost of power. 5.Allowing your firm 2 primary right to the potential advantages of lower-cost power capacity over the long term,in exchange for your participation at this time,The Intent of the draft agreementisforpurchasersatthistimetocontinuetohaveafirstrighttoavailableindustrialgeothermalpowerifthetotalloadatUnalaskagrowsbeyonditspresentsize.This right to capacity may constitute an asset that could appreciate in value over the years.

AEA and Beck will endeavor to complete contract execution the week of October 7. Also agreed that OESI will prepare a detailed project development schedule (including target dates for contract negotiation/execution, completion of consulting reports,permitting,and other key elements) for circulation in draft the week of October 7.This will be provided to the Unalaska City Council after review of draft schedule,and will be updated every two weeks.The idea is to begin to keep all parties, including the City Council,informed of project progress.Contracts include: 1)power sales agreement /AEA and the City 2)power sales agreements /City and processors 3)fluid sales agreement /AEA and OESI 4)construction contract /AEA and OESI 5)O&M agreement /AEA and OESI 6)possible --interconnection agreement /City and processors Also noted that,given shake-up at the Alaska Dept.of Revenue,this might not be a propitious time to ask for $11 million loan to establish capital reserve fund. A teleconference is scheduled for 1:30 p.m.October 11 to go over draft power sales agreement between City and processors (AEA to attend at Wohlforth's office).Meetings in Seattle with the processors are scheduled for October 24.A full meeting of the "finance team" (membership not entirely clear)is scheduled for November 4 in Seattle, expected to run all day.Brent needs to go over the budget upon his return to determine how much we can afford to pay for City of Unalaska travel for these types of meetings.At present,they intend to send several representatives and we will pick up the tab from the OESI "letter of commitment"money. Beck (Win Peterson)noted that AEA will-need some advice in negotiating the construction agreement with OESI,and asked if we had in-house expertise.I said I doubted we had the available engineering staff resources and information in-house to do a careful job of it.Peterson then said that Beck could serve in that role (i.e.advise AEA in construction contract negotiations with OESI).OESI was much in favor of this,and argued that getting another engineering firm involved would be confusing and time-consuming.I just said that there was a web of relationships here and that we would have to think about it.Basically, I'm not sure of Beck's allegiance in this. Two other miscellaneous items: 1)Our statutes require a feasibility study and plan of finance if the project "requires an appropriation from the state general fund"or "a pledge of the credit of the state."Still need clarification from Wohlforth whether: a)a loan from the Department of Revenue to set up a capital reserve fund; b)prior expenditure of $5 million in State funds; c)a general fund "loan"from the legislature (presumably an appropriation) 2) triggers this requirement.If so,Beck should be notified as soon as possible so that their report can be structured to cover the feasibility statute requirements as much as possible. It was noted that Tom Arminski is thought to be looking into right-of-way owners other than the Ounalashka Corporation.Need to follow up.
