Eric P. Youlrl Executive Oirpc+nr FROM: ~1ylPs C. Yerkes Director of Sv5tems & Planning Operations StaLe of Alaska DATE: FILE NO: TELEPHONE NO: SUBJECT: Marketino of Proiect " .... Power Under the EnProv Program for Alaska. - In discussino revisions to Power Sales Agreements required by ~ouse Pill #9 w'ith concerned utilities, ma.ior problems \'lith the Energy Progral'fl for Alaska surfaced. The Al a.ska Power Authority must consider modifica- tions to this program or othP.r actions necessary to secure power sales agreements with related utilities. Problems primarily relate to the inability of the current proqram to establish a reasonable and predictable ener~y rate for power customers under the program. Utilities voiced concern with current-program language which allows the debt service for a particular project t~ be increased bv thP Leoislature or the Power Authority without control by the utility. ·Utilities are understandably resistive to signing such ltTake or Pay 11 agreements since the ecor.omic impact to rel~ted communities could be devastating. The first major concern is the estimated initial cost of project power. Projected wholesale power rates by the financial group indicate Tyee at 18rt per kilowatt hour in the initial years of operation with a very slow tapering foll~winq that period. Since existinq utilities in the area (Wrang~11 and Petersburg) are currently generating power from diesel plants at a cost of approximately 10~ per kilowatt hour, it is difficult, if not impossibl~, to market the project energy at this rate. This problem is not exclusive to the Tyee project, but will in all probability arise for most projects in the program. Program debt service must bP. reduced to in turn reduce the initial wholesale power rate. Since the Power Authority has no means to generate such revenue, it appears that our only option is to request the State of Alaska to appropriate additional funds to pro(]re~.m construction to reduce future debt sP.rvice. Unless debt servicP. is reduced to allow marketing of project power at or slightly above the present cost of utility diesel gen~ration, I sincerely doubt utilities will complete or abide by the terms o~ existing or proposed power ~ales agreements. The second major concern is the inabi1itv of utilities to nredict future wholesale power rates due try cur·rent program language which allows debt service to be increased bv the Legislature through approval of additional projects tc the program or implementati~n of the "Susitna Rlackmai1 Clausen. "Take or pav 11 wholesale power agreement<.; with utilities are required to secure revenue bond financing o~ project costs above that appropriated by the State. For utilities to assume such a f'inancial responsibility, they must see a oredicable and reasonable wholesale power rate throughout the life of the contract. rurr~nt l~ois~atinn ~""~ nnt mP~ thi~ critnri~ ~inc~ costs r~n b~ un11at~rallv i!'lCrP:;c;Pd t0 th.::o ut Htirc-, hy th(l P'11riP.r 1\ut.hnritv fl0;:~rri 'lr the L~qisl~tur~ without concid~r~tin~ o' al'~rn~tivp~ to th~ utflitv.

This program, l1ke many other energy programs elsewhere, now needs to be reviewed in the light of the currently prevailing circumstances under which some of the projects are expected to be· substantially debt financed and may come on stream at a period when there has been a significant weakening in thermal energy prices. This poses a number o-f problems which need to be addressed in the context of the HB 9 legislation which effectively interlocks the power rates of a 11 projects in the system. The paper first describes the essentials of the HB 9 legislation and then considers the present status of the first four authorized projects (Swan Lake, Tyee Lake, Solomon Gulch and Terror Lake) in the light of this legislation. lt then outs forward a number of possible solutions to the problems posed by this legislation for consideration by the Board before further development proposals are presented to the legislature. This presentation focuses on the rate setting formula and presents four alternatives to attain a wholesale power rate comparable to the projected thermal rates. This approach may inadvertantly create the impression that HB 9 is itself a problem. However, the Power Authority does not in any way take issue with the legislation and believes that HB 9 is an equitable and workable rate setting mechanism. 2 -DESCRIPTION OF HOUSE BILL 9 2.1 -Historv During the last session of the Legislature, HB 9 (subsequently enacted as Chapter 233, SLA 1982) was adopted to amend the Energy Program for Alaska. The major and most detailed change introduced by HB 9 was to establish a system related but project-specific wholesale power rate rather than a single system-wide wholesale power rate. Under the previous legisla- tion, the single wholesale power rate was calculated by totaling the opera.tion and maintenance costs, inspection fees, and debt service .costs for all projects in the system, then dividing by total sales to arrive at a cents-per-kilowatt hour rate, which would be applied to all project sa 1 es. The new and somewhat comp 1 ex power rate system is outlined below. 2.2 -Wholesale Power Rates Under HB 9 Under the new HB 9 legislation a project's power rate vlill be based on the followina three components: (1) it's own operation and maintenance costs, (2) ft•s own inspection fees, and (3) a portion of the total system debt service. 2 The 0/M and inspection fee portion of the power rate is simply the actually incurred costs divided by project sales. The debt service portion of any individual project's power rate is the most significant aspect of the legislation and is most easily described by the following formula. The debt service component is where ~) ( X -y ) Z ( y - p ) x = the state's total investment in the particular project y = the state's total investment in all projects within the energy program for,Alaska z = total debt service including coverage for all projects for the year in question p = the amount of principal repaid as at the date of the calculation This formula, however for our present purposes, simplifies to: X t' Y 1mes z Thus total system debt service z is allocated to individual projects on the basis of the project's share (x/y) in the total investment by the state. This formula holds, regardless of whether a project itself has incurred any debt service. In essence, this formula therefore allocates debt service so that each project pays the same amount of debt service relative to project cost as all other projects. Thus the benefits of state grants, directed towards specific projects, will be shared by all. This methodology is complicated by subsection {c) (h) of the legislation which places a "cap" on the level to which the debt service component of the wholesale rate can increase in any one year. The 11 Cap 11 rate each year is eoual to the average system debt service rate (total system debt service divided by total sales) times a factor which increases by four percent per annum from one in 1983. If any projects have the debt service portion of their rates capped then the other projects, whose rates are still less than the cap rate, will have their rates adjusted upwards {to a maximum of the cap rate) so that sufficient revenues are collected to meet debt service obligations of the entire system. This allocation of the remaining debt service is again based on project cost. This "cap 11 provision applies only to Swan, Tyee, Terror and Solomon Gulch. In consequence, any new projects will have to carry a corre- spondingly higher burden of debt service. The final wholesale power rate then is the sum of the operating cost rate and the debt service rate. Further details of the methodology for power rate calculations is contained in Appendix C. 3 ...

" 3 -WHOLESALE ·POWER RATE FORECASTS FOR; SWAN LAKE, TYEE LAKE, SOLOMON GULCH AND TERROR LAKE In this section the effect of the HB 9 legislation on wholesale power rates for the Swan Lake, Tyee Lake, Sol oman Gulch, and Terror Lake projects are examined to the year 2001. Power rate calculations und!r HB 9 depend not only on the usual parameters such as project cost , sales and financing, and economic variables such as inflation and interest rates, but also on which pro.iects are included in the calcu- lations. For example, Solomon Gulch, with a current wholesale rate of 3~/kwh, would see its rate increase substantially when the Swan Lake and Tyee Lake projects are brought on-line and into the calculations in FY 1985. 3.1 -Forecast Assumptions The forecasts presented are based on the assumptions detailed in Appen- dix B. A detailed description of the forecast methodoloqy and model are provided in Appendix C. 3.2 -Wholesale Power Rates Table 1 gives the wholesale power rates for each of the four authorized projects under the existing HB 9 legislation. The table is essentially for record and does not compare the results with the cost of therma 1 power. This is considered in the fuller context of the analysis of Section 4.

This in outline provides (with some limitations} for 95· percent of the cost of power in excess of 15 cents per kwh in 1985 to be covered by State grants to the utility. T~is reference level of 15 cents in 1985, however, increases by one (1) cent each year. The effect of this in mitigating the early year cost of the hydro projects is shown in Table 2 in the context of the retail power rates to which the Power Cost Assistance Program provisions apply. It is seen from this that after the power assistance grants, the average net retail cost (after the Power Cost Assistance is applied) of the hydro power to consumers is competitive with that of thermal for all projects in 1985. The effect of Terror Lake coming on in 1986 is to introduce a jump in the cost of power for the whole system. This occurs as a result of the debt/eouity ratio for Terror Lake which is substantially below the system average. This, as also shown in Table 2, results in Tyee Lake having a cost of power nine percent higher than thermal.

See Appendix A for project descriptions 5 . . It is possible that these temporary differentials, in net cost, will be lower and that they will be acceptable to the local utilities as a small price for the major long term benefits conferred by having large re- sources of low cost hydro power indefinitely. The .Power Authority planning must, however, prepare for the contingency that this is not the case since, short term, it depends both on the unpredictable short term cost of fue 1 oi 1 and on the continuance of the Power Cost Assistance Program. It is also possible that the utilities will wish to negotiate the power rate, while ignoring the Power Cost Assistance Program. The following section, therefore, reviews the HB 9 legislation and the competitive position of the hydro development at the wholesale power rate level excluding the mitigation effect of the Assistance Program. 4-THE EARLY YEAR POWER COST, SYSTEM INCREMENT AND UNIFORM RATE PROBLEMS UNDER HB 9 4.1 -The Problems The wholesale power rates as they stem from existing legislation (and as shown in Table 1) need to be considered in the context of the estimated cost of thermal power generation from existing capacity in the areas served. Here the economics of the Swan, Tyee and Terror Lake projects are each seen to be materially affected by three interrelated problems arising from their basic economics and the impact of the HB 9 legis- lation. The problems are: The Early Year Power Cost Problem This is the problem of .the recent weakening of oil prices which may result in making the early year cost of power from the hydro projects being higher than the early year cost of the diesel operation which they displace. The Svstem Increment Problem This is the problem of all power rates on the system being increased through the HB 9 mechanism when a new project is introduced to the system and the project has a higher proportion of debt finance than the average of the existing system as a whole. The Terror Lake project is more heavily debt financed than the existing projects (5R percent compared with 26 percent). When this project comes on stream in FY 1986 the effect of HB 9 is to share this increased cost of debt service among all four projects and so further increase the cost of power for Swan Lake, Tyee Lake and Solomon Gulch . The Uniform Rate Problem The HB 9 legislation requires that a single-power rate be established for each project. As noted in Section 5, this creates underutilization and consequently higher unit costs by precluding the Power Authority ~ . .; f:"'> I' ,., The effect of the early year power cost problem alone is shown in Table 3 on the assumption that diesel oil costs increase by only the rate of inflation between the end of 1983 and the first year of service (FY 1985). On this assumption, in 1985 all projects show power rates less than local thermal generation cost. · However, a problem occurs when Terror Lake is brought into the calculations in 1986. This is the System Increment problem -the effect of HB 9 when a higher r;:._ than system average debt financed project is added to the system. When this occurs it is seen from Table 3 to have the effect of: (i) increasing the cost of power of Swan and Tyee over their 1985 level by 32 percent and 31 percent, respectively (even with the 11 Cap 11 in place); (ii) making the cost of power of Tyee Lake 15.8 ¢/kwh compared with 13.4 ~/kwh for diesel generation. Terror Lake itself, with its higher debt service, would come in at approximately the same cost as thermal. On the inflationary assump.tions given, it would take four years to close the net cost gap between thermal and hydro for Tyee Lake. 7 ,..,, .... ,, ·-"~ r·..,.. ; ~ ..... . ... . ..

The System Increment problem, however, is of considerably great seriousness first, because it com- pounds the Early Year Power Cost problem by increasing the cost of power whenever heavily-debt financed projects are added to the system. Second, and of more importance, it places the utilities in a position of appreciable uncertainty as to the future burden of power costs which ·they might be obliged to assume through the HB 9 mechanism. It is true that the HB 9 mechanism does provide a "cap" for the existing four projects on the rate of increase of individual project power rates resulting from new increments to the system. But this does .not rectify the basic fact that over the long term, utilities coming into the system are exposed to what might appear an open-ended liability to meet their share of whatever the debt service cost is of additional increments to the system. This was not a material issue while expectations were that the hydro power, even in the early years, would be less expensive than the highly escalating cost of the thermal option and there was the general expectation that the hydro additions would, in very large measure, be financed by equity contributions from the State~ With the weakening of both these expectations, a concern on the part of utilities joining the system as to the extent of escalation in future hydro power costs is understandable. It is also possible that this combined with the Early Year Cost of Power problem {which it exacerbates) will result in.difficulties in negotiating contracts with the local utilities. This problem has no easy solution. A range of possible solutions have been considered and are as outlined below. 4.2.1 -Stand Alone Leg~slation The first option to be considered is that of amending HB 9 such that future projects had a calculated cost of power which was on a stand- alone basis, that is, the "new 11 projects were exempt from the HB 9 debt service sharing provision. This would indeed shelter the existing projects from any high debt service component of new projects, but would have the obvious serious disadvantage of 1 eaving these new projects disadvantaged relative to the projects which preceded them under the HB 9 legislation. At a practical level it would also appear to be unacceptable since, for example, in the case of Terror Lake it would imply a wholesale cost of power in the first year {1986) of 15.4 cents and 25 percent higher than under HB 9. Rather than meet this cost of power. {estimated to be some 25 percent higher than that of the thermal option) the local utilities might feel obliged to forego the very substantial long-term advantage which would be conferred by the fact that the cost of the hydro power would be virtually fixed in money terms. 9 In summary, the 11 Stand-alone 11 solution would involve the probability of foreQoing the long-term falling real cost of power which the present hydroelectric program is designed to achieve. 4.2.2 -Higher State Equity Contributions Higher State Equity Contributions than those which form the basis of the forecast power rate of Table 1 would have the overall effect of reducing power rates and so helping to resolve the Early Power Cost and System Increment problems. The major difficulty with this solution, however, is that the HB 9 legislation effectively shares the benefits of any larger state equity in any particular project between all the projects in the system thus reducing all power rates. In consequence, higher State Equity contributions to reduce the cost of power, in the case of Lake Tyee for example, would have the ·effect of reducing not only the Lake Tyee power rate, but a 1 so the power rates of Swan Lake, Terror Lake, and Solomon Gulch, although the last would already have a power rate 50 percent less than the cost of thermal under the existing proposed financing. Moreover, this sharing of the benefits of greater state equity of necessity, means that much larger state equity is required to reduce the power rate of any given project. The numerical effect of this is shown in Tab1e 4. TABLE 4 WHOLESALE POWER RATES RESULTING FROM ADDITIONAL STATE EQUITY CONTRIBUTIONS Swan Solomon Gulch Thermal Rate 1985 1986 1987 HB 9 Rate Under Base Financing Assumption 1 1985 1986 1987 HB 9 Rate After Additional State Grants of $40 million 1985 1986 1987 14.1 15.2 16.3 11.4 15.0 15.1 11.4 12.5 12.7 12.5 13.4 14.4 12.1 15.8 16.1 12.1 13.4 13.7 18.1 19.5 20.9 9.7 10.1 10.1 9.7 8.6 8.8 Terror N/A 13.0 14.0 N/A 12.3 11.7 N/A 9.9 9.6 1 See Appendix B Tota 1 state contributions assumed to be $281 million (approximately 60% of total financing) : ,;_ l This estimates the total additional equity contribution which will be required to ensure that all the power rates from the authorized projects are below the cost of thebest thermal option. As seen from Table 4, Lake Tyee presents the most serious problem with a cost of power 2.4 cents higher than the thermal cost in 1986. Consequently, the equity contribution would be determined by whatever was required to achieve this objective. It would, however, require $40 million of equity. As can be seen from the table, this makes Lake Tyee equal in power rate to the cost of therma 1 by reducing the cost by 2. 4 cents. But it a 1 so reduces the cost of power for Swan, So 1 oman Gulch, and Terror Lak~ by 2.5, 1.5, and 2.4 cents . respectively in 1986, thus bringing their cost well below the cost of thermal power in their areas. This is again beca~se the high equity contribution to Lake Tyee has the effect, through the operation of HB 9, of reducing all other power rates. It is because HB 9, effectively makes it necessary to reduce all power rates in order to reduce any one of them by greater equity! that the magnitude of the equity contribution at $40 million is so large. 4.2.3 -Low Interest Rate Loans The Early Year Power Cost and System Increment problems could also be reduced by the state providing financing in the form of low interest rate 1 oans. The 1 arger the amount of such 1 oans and the 1 ower the interest rate, the lower the burden of debt service which HB 9 would require to be shared among all the projects on the system. This solution, however, has much the same disadvantages as the higher state equity proposal considered above. Again the whole of the benefit of this low cost form of financing would be shared among all projects on the system irrespective of their power. rate so that the problem of sharing applies here as in the equity financing case. Moreover, in terms of the total level of appropriations required, this proposal would require very much higher appropriations than in the greater state equity case. This is because it would require $2.4 million of (say) five percent interest rate money to reduce power cost by as much as Sl million of state equity since the latter involves no burden of interest or repayment. Hence the low interest loans will have all the adverse affects of greater state equity and the addition \vould require appropriations 140 percent higher to achieve the same impact on the power rates. 4.2.4-Equalization Grants as an HB 9 Over-ride It is clear from the options considered above that any state assistance in meeting the Early Power Cost and System Increment problems through state fi nanci no assistance is made very costly by the effect of HB 9 sharing the benefits among all the projects on the syst.em, irrespect~ve of their existing power rates. Economical and effect1Ve state ass1s- tance therefore, needs to be in a form which was not treated in this way by the HB 9 division and so could be directed at the particular projects which have the Early Year Cost of Power and System Increment prob 1 ems. 11 This could be achieved by a system of annual "Equalization Grants 11 directed towards making the cost of power from the hydro station equa 1 to that of thermal alternative, until such time as the increase in fuel costs on the thermal alternative brought its costs up to that of hydro and thus made further Equalization Grants unnecessary. To ensure that such grants were not swept up by the HB 9 legislation and the benefits shared among all projects irrespective of need, it will be necessary to legislate that the Equalization Grants were not to be taken into account in the application of HB 9. Specifically, the legislation might take the following form. It would apply to areas where the cost of power from the hydro source was higher than the existing thermal power option. The program would then under- take for, say, a five to six year period, a special "Equalization Grant". This grant would meet the whole of the estimated· difference between the cost of the hydro power and the cost of the thermal power as estimated each year based upon the price of diesel oil. In the case of Tyee Lake, where the early year cost problem has been seen to be most material under HB 9, the cost of this (on the assumption of diesel oil prices increasing at the rate of inflation from 1984) would be approximately $1.8 million in then current dollars (approxi- mately $1.4 million in 1983 dollars). The year-by-year costs of the Equalization Grant are shown in Table 5 in then current dollars. On the inflation assumptions assumed, the Tyee Lake power rate would be competitive with that of thermal at the end of four years so that the Equalization Grant could be terminated. Thereafter, as already noted, the cost of the hydro power would be falling progressively in terms of constant dollars as inflation progresses.

The total cost in the latter case, however, is likely to be relatively small given that with this solution to the systerrt increment cost pro- blem, their cost of power would become competitive with thermal within a very ·short period. The Equalization Grant provisions could be written into the power contracts of the utilities with the Power Authority, thus giving the assurance of their continuation over the appropriate period. 4.2.5-Equalization Loans An alternative to the Equalization Grants would be Equalization Loans. These would be simply the grants made repayable at a date when the hydro power was competitive with the thermal alternative. Under this proposal the grants would be carried .as an unsecured loan for a given period - for example, eight years from the commencement of the grant. By this date, the hydro power should be strongly competitive with the therma 1 option. In consequence, by this time it should be possible for the utility to accept an increase in the power rate, which would be suffi- cient to support long-term commercial borrowing with the proceeds of the borrowing going to repay the outstanding 1 oan accounted for by the Equalization Grant. This proposal would involve some technical problems in the debt fi- nancing. It would, for example, be necessary to secure the prior consent of the existing bond holders for this additional subsequent borrowing, and the terms on which the borrowing would take place would need to be precisely and legally specified if the existing bond holder interests were to be protected. These problems, however, would have to be overcome without undue difficulty if this particular proposal won the consent and cooperation of the utilities concerned. There might remain the problem for the uti 1 ities that they would be subject to uncertainty as to whether or not the Equalization Grant would apply to later increments to the system or whether, after their own Equalization Grants had run out, they were to be subject to the effect of the System Increment problem as other projects with relatively high debt service were added to the system and were not in receipt of Equalization Grants. This potential exposure, however, might be acceptable to the utilities given they had the shelter provided by the Equalization Grants over the first five years and the then highly competitive economics of their own sources of hydro. Turning to the economics of the Equalization Grant system from the stand point of the State of Alaska, it is seen from Table 5 to involve only $1.8 million in total ($1.4 million in 1983 dollars). Against this must be set the major long term economic advantages of reduced future costs from the hydro program. 13 4.2.6 -Standardized State Financing Until System Maturity It has been seen that the System Increment addition problem essentially arises where the increment to the system has higher debt service costs than the then existing units in the system. This particularly arises with Terror Lake where it is 58 percent financed by debt compared with 26 percent for the system as a whole. A means of substantially eliminating the System Increment problem would therefore be to ensure that for an interim period at least {for, say seven years) additions to the system were financed with the same proportion of debt as the existing system -that is only 26 percent with the balance being funded from state equity. This would be needed for only an interim period until the system was established and like other "mature" power systems, begin to reap the benefits of decreasing cost of power in constant dollars from the substantial amount of capacity acquired in the past. This measure would realistically address the fundamental problem which all newly estab- 1 i shed power systems pose, namely that they have no backlog of cheap capacity acquired at the lower prices prevailing in earlier years. In consequence they have an inherent problem introducing into the system new units of capacity, the current costs which, in an inflationary world, inevitably involve higher costs than units purchased at the substantially lower prices prevailing in earlier years. If this problem is not addressed and resolved it would result in the system being permanently locked into whatever types of capacity have the lowest early year costs irrespective of the long term economics. The Standardized Financing Option would be a solution which, within existing legislation, would create a "mature" system such that the power rates resulting from this option would all rapidly become competitive with the existing thermal option so that within a few years other units could be introduced into the system without causing excessively large increases in power rates. The evident major problem with this option is that it would involve additional equity of approximately $60 million to be appropriated in FY 1984 and 1985 and as such may be deemed unacceptable. 5 -MARKETING AND DEVELOPMENT SOLUTIONS The preceding sections have addressed the immediate problems in a legislative context since these need detailed and lengthy consideration prior to legislation. The Power Authority is, however, actively pur- suing the marketing and development activities which will help improve the economic comoetitiveness of the projects under construction or authorization. This includes: (1) Transmission interconnections to serve adjacent communities or interties; (2) Securing home heating markets and (3) New industrial and commercial loads. 14 f Very substantial potential increases in sales of power (and consequent reduction in unit costs) are possible given that the three projects have substantial underutilized in the early years and, in the case of Swan Lake, only about 40 percent. The uniform rate imposed by HB 9 for all power from a given project is a serious obstacle to the greater utilization of capacity by securing home heating and industrial and commercial loads. These loads can only be secured on the basis of a price of power·significantly lower than the· single wholesale rates of Table 1. On these grounds, it is recommended that HB 9 be modified to permit multiple tariffs whenever this is shown as likely to improve utilization and reduce unit costs overall. 6 -SUMMARY AND CONCLUSIONS 1. The report reviews the key elements in the Power Authority's hydroelectric program in the light of the issues posed by the recent weakening of alternative energy prices, the present stage of development of the projects, and the impact of the HB 9 legislation. 2. The HB 9 legislation is designed to share the debt service cost of all projects on the system between all projects, irrespective of the actual level of debt service which they have incurred indi- vidually. The allocation of the system debt service between individual projects is in proportion to the percentage which the state investment for each project represent of the tota 1 state investment for all projects. If, for example, the inve~tment in a particular project represented 20 percent of all such investment it would have to carry 20 percent of all the debt service on the system. This means that the power rates of individual projects are not fixed but wi 11 increase if new projects with heavy debt fi- nancing are added to the system. This is referred to below as the System Increment problem. 3. This legislation and the weakening in diesel oil prices has created. three separate but inter-related problems. These are: The Eqrly Year Power Cost Problem -the problem that a weak- ening in the cost of diesel oil can make a new and substan- tially· debt financed hydro project uncompetitive with the thermal alternative it displaces in the early years. The Sfstem Increment Problem-the phenomenon of additional, large y debt financed project increasing the power rates on all the existing projects. The Uniform Rate Problem -the problem that HB 9 calls for each project to have single uniform wholesale power rate. 15 . ' •---· 4. These three problems represent significant difficulties in the marketing of hydro-electric power and the realization of the long term economic benefits of this renewable power source. Utilities may be reluctant to take the hydro-electric power where it involves higher early year power costs and may also be reluctant to enter into long term contracts given that the System Increment problem presents them with an indeterminate future cost of power. The Uniform Rate problem also makes it difficult to resolve the prob- lems by securing greater sale since it precludes offering lower tariffs to secure "low cost 11 loads such as those offered by indus- trial demand and the home heating market. 5. These problems are illustrated by an analysis of the Terror Lake, Swan Lake, Tyee Lake and Solomon Gulch project. 0 0 Prior to the tntroduction into the system of Terror Lake, Swan Lake, Tyee Lake, and Solomon Gulch are all com- petitive with the cost of the thermal power which they displaced. Adding Terror Lake (with its 58 percent debt financing) to the system in 1985 highlights the increments to system problem. Through the HB 9 mechanism this increment to a system has the effect of increasing the power rates of all the projects on the system and in particular making Tyee Lake 2.4 cents more costly than the cost of thermal power. 6. While these problems· are inherent in the HB 9 legislation their numerical magnitude results from the small size and recent estab- 1 i shment of the system. This means that any new project can be relatively large compared with the rest of the system, and because the system is relatively new it does not have a large base of old assets acquired at the much ·lower prices obtained years earlier into which to easily assimilate any new high cost source of power. 7. A wide range of possible solutions to these problems were con- sidered in Section 4 including greater state equity contributions, lower interest rate loans, etc. The problem, however, is to find a solution to these problems that is economical in terms of the magnitude of the state contribution required. ThP HB 9 legislation makes the additional state equity solution very costly since this leaislation would share the benefits of such contributions between ali projects in the system thus reducing all power rates irrespec- tive of the extent of which they were already competitive with therma 1. 16 .. . . 8. In the light of this· analysis it is concluded that the most econom- ical and effective means of resolving the problems indicated in paragraph 4.2.4 would be that of "Equalization Grants 11 • These would be special state grants designed to reduce the cost of the hydro power in the early years into equality with the cost of the thermal power which it displaces. On present forecasts, grants would only be required for Tyee Lake for a period of four years. The total cost (in 1983 dollars) would be $1.4 million compared with approximately $37 million· in the case of the additional state equity. 9. It is expected that the Equalization Grants might be necessary for a number of projects unti 1 the system achieves the 11 maturi ty 11 and competitiveness inherent in the 1 ow esc a 1 at ion rate of hydro and thus becomes able to absorb new high cost additions to the system without unacceptably high increases in power rates. 10. Turning to the Uniform Rate problem, it is concluded that this is a material obstacle to greater utilization of the hydro projects and prevents the system obtaining lower unit costs by supplying the industrial and heating markets. It is recommended, therefore, that consideration be given to changing the legislation to permit the Power Authority to establish multi-rate tariffs wherever this appears likely to secure larger markets and hence lower unit costs. Given such legislation the Power Authority would expect to be able to significantly improve the competitiveness of the hydro power projects. 11. In summary, the HB 9 legislation as it now stands poses significant problems for the hydro-.e l ectri c deve 1 opment program at its current relatively immature stage of development and in the context of the weakening in thermal fuel prices. Legislation along the lines indicated in paragraph eight and paragraph ten of this section wou 1 d, however, reso 1 ve these prob 1 ems and enab 1 e the program to realize its ultimate objective of long term low cost power for most Alaskans . 17 r ~. ~-· APPENDIX A A.1 I. SWAN LAKE HYDROELECTRIC PROJECT HISTORY AND DESCRIPTION The City of Ketchikan, having made the decision to discontinue its reliance on the use of diesel electric generation to meet rising energy demands, authorized the engineering firm of R. W. Beck in September of 1977 to investigate the feasibility of developing, as a major hydroelectric generating resource, the Swan Lake Project which is located approximately 22 miles northeast of Ketchikan near the northern end of Carroll Inlet in the central portion of Revillagigedo Island. In June of 1978, R. W. Beck issued a feasibility report indicating that a hydroelectric project which would demonstrate a benefit/cost ratio of 1.25 could be conitructed at Swan Lake at a total investment cost of $80,924,000. Subsequently, the City of Ketchikan, Ketchikan Public Utilities {KPU) au-· thorized R. W. Beck to proceed with preparation of final design of the project. The 1980 Legislature through joint resolution authorized the Alaska Power Authority to issue bonds up to the maximum amount of $120,000,000 for financing the construction of the Swan Lake Project. Construction was initiated by KPU in November of 1980. Funding for project design and initial construction was secured primarily through the proceeds of loans from the Power Authority's Power Project Revolving Loan Fund. · On May 28, 1981, the Power Authority 1 oaned KPU $35 ,000,000 for con- struction from funds which had been raised through the sale of General Obligation Bonds. On May 21, 1982, the Power Authority and KPU executed an acquisition agreement under which, in return for providing funds to complete project construction, the Power Authority will receive title to the project and as operation of the project will provide sufficient power for the City of Ketchikan•s needs via a Power Sales Agreement. The Swan Lake Project consists of a dam, a power tunnel and a powerhouse situated at tidewater on Carroll Inlet, plus approximately 30 miles of transmission line from the site to Ketchikan. The dam, which is essentially completed, is a double curvature concrete arch structure 1 ocated about 0. 75 mi 1 e downstream from the outlet of the existing Swan Lake. The dam has a maximum height of 174 feet above the base of the foundation excavation. The dam crest of e 1 evati on 344 above mean lower law water (MLLW) is 428.5 feet long. The dam has a crest thickness of 6 feet and has a base thickness of 16.5 feet. A 100-foot wide ungated agee service spillway section with the crest at elevation 330 is located in the central portion of the dam. Spillway . ' f. discharges will be flipped downstream from the toe of the dam to a plunge pool excavated in rock in the existing stream channel. The spillway is designed to pass a Probable Maximum Flood which is.estimated to have a peak inflow of 37,150 cfs and a volume of 38,700 acre-feet. i i . . A.2 I. TYEE LAKE HYDROELECTRIC PROJECT HISTORY AND DESCRIPTION On December 19, 1979, the Alaska Power Authority submitted an application to the Federal Energy REgulatory Commission (FERC) for the construction of the Tyee Hydroelectric Project in the vicinity of Wrangell and Petersburg, Alaska. Our engineers, R. W. Retherford Associ- ates/International Engineering Company (IECO), estimated the cost of the project at that time at $53,333,000.00, including an allowance for inflation at the rate of seven percent per year during the construction period. Procurement of long-lead-time turbines began in July 1981, in anticipa- tion of a FERC license. FERC issued a license August 5, 1981, and the award of severa 1 addi ti ana 1 procurement and one construction contract fa 11 owed almost immediately thereafter. The power-on-1 i ne date is schedu 1 ed for January 1984. The current estimate of the total project cost is $124,000,000.00. Available funds include $82,000,000.00 in State grants and $50,000,000.00 in interim financ- ing. The powerhouse is located in the Tongass National Forest, approximately 40 miles eastsoutheast of Wrangell, Alaska. The project is designed to develop the energy potential of Tyee Lake--a natural lake at Elevat"ion 1396---convert it to electricity, and transmit the energy to the communities of Wrangell and Petersburg for distribution. The project includes the following principal features: 1. A tunnel system between Tyee Lake and a powerhouse, which is located at sea level on the south side of the Bradfield River valley. The tunnels consist of approximately 4,770 feet of 10-foot diameter tunnel, 1,880 feet of 13-foot diameter tunnel, and 1,380 feet of 10-foot diameter vertical shaft, all nominally unlined. The tunnel will contain a rock-trap, tunnel plug, access gate, steel penstock, and manifold. The tunnels wi 11 be connected to Tyee Lake by the 11 Lake-Tap 11 method at a water depth of approximately 140 feet. A dam is not required. 2. A gate-shaft near the upstream end of the tunnel, consisting of approximately 420 feet of vertical, 12-foot diameter shaft, containing an intake gate, stoplog, and fine trashrack . 3. A powerhouse containing two, 10-MW hydro-generating units with provision for a future third unit. There will be an adjacent outdoor switchyard. 4. 5. A 1200-foot lana tailrace for discharging water from the powerhouse to an existing slough. A 138-kv transmission system, 81-miles long. Approximately 60 miles will be overhead line and 12 miles will be underwater in four separate crossing. r·· .. . ' A.3 I. SOLOMON GULCH HYDROELECTRIC PROJECT HISTORY AND DESCRIPTION The Solomon Gulch Project, located outside of Valdez, is a 12 MW hydro- electric project owned by the State of Alaska. Associated with the Project and also owned by the State are approximately 100 miles of 138 KV trans- mission line connecting the Project with Valdez and Glennallen, and three substations. The Project has been operation a 1 for a year and during that time has been operated for the State by the Copper Va 11 ey Electric Associ- ation (CVEA}. Under agreements between the Authority and CVEA, it is expected that CVEA will continue to operate the Project for the State and, as has been the case for the past year, CVEA will continue to be the sole purchaser of the output of the Project. The average annua 1 generation from the Project is expected to be 55,000 MWH, although at the present time, CVEA can use only approximately 40,000 MWH per year. CVEA is presently paying three cents per KWH for the project output. On June 21, 1978, the Federal Energy Regulatory Commission (FERC} granted CVEA a license to construct, own, and operate the Solomon Gulch Hydroe-lectric Project. The project· site faces the City of Valdez from the opposite shore of Port Valdez and is located approximately 3 miles east of the Trans-Alaska Pipeline Terminal. The site was originally licensed in 1932 for a 480 HP project construc- tion in 1907. This project was operational until 1945 when the license was surrendered to the Federal Power Commission (FPC}, forerunner to the FERC}. In 1952, the FPC issued a 1 i cense for a 225 HP project which was to be a partial restoration of the original project. This project was never con- structed, and at the time of the application in 1975 by CVEA for a license to construct the project as it presently exists, all that remained of the original project was the 100-surface-acre reservoir (Solomon Lake}, scattered remnants of the penstock and powerhouse machinery, and a deteriorating operator 1 s cabin. CVEA proposed to replace the existing dam at Solomon Lake, raising the normal elevation of the lake from 610 feet to 685 feet. Surface area of the reservoir waul d be increased from 100 to 660 acres, and storage capacity would be increased from 1,700 acre-feet to 31,500 acre-feet. The power plant was proposed to produce 12,000 kilowatts of capacity with an annual average energy output of approximately 55,596,000 kilowatthours. CVEA, an REA borrower serving Glennallen, Valdez, and an irregularly shaped service area in between the communities, has realized substantial growth in recent years, mostly due to the increased population and industria1 activity generated by construction of the pipeline. The Solomon Gulch Project was determined to be the most economical means of supplying the additional generating capacity needed by CVEA and of providing an intercon- nection between the Glennallen and Valdez distribution systems. Using REA and CFC loans for funding, CVEA began construction of the project. In 1981, prior to completion of the project the State of Alaska, directed the Alaska Power Authority, to approach CVEA about the idea of purchase of the project from CVEA. It. was felt that by us~ng funds appropriated by the State for the cap1tal costs of the proJect, the f . . . costs of the utility, and hence its customers, would ·be less. The State and CVEA signed an Acquisition Agreement in 1981 whereby the State assumed the project and all costs and debt associated with the project. Agreements were also signed specifying the conditions under which the project would be operated by CVEA for the State and under which the entire output of the project would be sold to CVEA. Construction of the project and the transmission line was completed in January, 1982, and commercial operation of the project began on March 31, 1982. The FERC license for the project was transferred to the Power Authority on May 28, 1982, and the Power Authority assumed full ownership of the project in July, 1982. Since that time, the project has been operated by CVEA for the Power Authority with sa 1 e being made to CVEA of the usab 1 e output of the project. . ' A.4 I. TERROR LAKE HYDROELECTRIC PROJECT HISTORY AND DESCRIPTION The Terror Lake Hydroelectric Project was initiated by the Kodiak Elec- tric Association (KEA) in the mid-1960's to provide lower cost electrical power to its customers. Tippetts, Abbett, McCarthy and Stratton and Robert W. Retherford and Associates were retained to prepare a feasibility study which indicated the the project was not economically feasible at that time. The rapid rise in the cost of diesel fuel in the mid-seventies ~resulted in KEA retaining Robert W. Retherford and Associates and Inter- national Engineering Company to upgrade the previous feasibility study, apply for a Federal Energy Regulatory License and to accomplish the project design. The application for a license was submitted to the Federal Energy Regulatory Commission (FERC) in December 1978, and their initial review indicated that more environmental data was required. The additional data was acquired during 1979 and was submitted to FERC in February, 1980. The Department of the Interior, the Alaska Department of Fish and Game, the Legal Defense Fund of the Sierra Club, the Audubon Society and the Northwest Wildlife Federation were granted interventions by FERC. By letter of July 28, 1981, KEA trans- mitted an Agreement between KEA and the interveners in which the interveners agreed to withdraw their objections in return for certain additional stipu- lations. The FERC License was issued to KEA on October 5, 1981, and transferred to the Alaska Power Authority on May 12, 1982. The Terror Lake Hydroelectric Project is located on Kodiak Island as shown in and is about twenty-five miles southwest of the City of Kodiak. The principal components of the project consist of the following: The natura 1 storage of Terror Lake wi 11 be increased by 108,000 acre-feet by building a dam across the lake's natural outlet. This dam will raise the water surface level from the present elevation of 1,250 feet to a maximum elevation of 1,420 feet. The dam wi 11 be a compacted rockfi 11 structure with an upstream concrete face. It wi 11 have a maximum structura 1 height of 193 feet and an effective crest elevation of 1,420 feet. A sidechannel spillway will be excavated in the rock of the right abutment. It will be ungated and unlined, and it will have an inlet crest 625 feet long. A reinforced-concrete outlet conduit will pass through the base of the dam, and will be used to make controlled releases down the Terror River for maintenance of the fish spawning beds. A power tunnel will leave Terror Lake from an intake structure on the eastern shore and head northeast for 26,300 feet to an outlet portal on the slopes of the Kizhuyak Valley. It will have an 11-foot-diameter section, and will be unlined, with only nominal lengths of concrete lining and other supports as required. Runoff from the 15.1 square miles of the natural catchment area of Terror Lake will be supplemented by diversion from 8.6 square miles of adjacent catchment areas. These areas are Shotgun Creek, Falls Creek, Rolling Rock Creek, and Mount Glotoff Glacier. The diversions will be accomplished by small diversion dams, open . ,-. ' i. f . - channe.ls, and intake tunnels and shafts connecting into the main power tunne 1 • One of these shafts (of Ro 11 i ng Rock Creek) wi 11 also function as a surge shaft. Provisions have been made in the design for the future diverston of the runoff-from 4.0 square miles of the Upper Hidden Basin Creek catchment area and the 5.1 square miles of the Upper Uganik catchment area. A single, inclined, steel, penstock, 3,100 feet long, will extend from the tunnel outlet portal, down the side of the Kizhuyak Valley, to an above ground powerhouse located on the valley floor. The powerhouse will contain two vertical-axis, 18,336hp Pelton-type, 6 nozzle impulse turbines, each connected to a 10-MW electrical generator. Thus, the total initial installed capacity will be 20 MW. The turbines, which will be set at Elevation 103.5, will operate at an average net head of 1,207 feet. Provisions will be made for a future third generating unit in the powerhouse, and the power tunnel and penstock have been designed to accommodate the additional flow, without modification. Transmission of the electric power to Kodiak will be via a single circuit, 138-KV, 19 mile long transmission line, using a combination of steel and wooden pole structures and AACSR conductor .

A provision for working capital has been included in this analysis as well as a general reserve and contingency fund. Working capital is assumed to be met by short-term debt, with an annual interest rate of ten percent. The reserve and con- tingency fund earns interest at ten percent per annum, (on the previous year's ending balance}. 2. The annual provision for renewals and replacements (0.3 percent of project construction costs (excluding IDC) per annum} is assumed to be funded with bond coverage where possible. If this coverage proves to be insufficient, then revenues (and rates} are increased so that this shortfall is just met. ' . Methodology Used to Calculate Debt Service Portion of Wholesale Power Rates 1. Calculate Average System Debt Service Rate (R1) R1 = (Total System Debt Service + Coverage)/Total Sales for all Projects. Rl = (A+ B)/SUM(E). 2. Determine System Cap Rate (R2) {see Subsection 44.83.398(2)(h)). R2 = System Debt Service Average x (1 + .04 (year-1983)). R2 = Rl X (1 + .04 x C). 3. Calculate each project's·initial, proportionate share of total debt services and Without Cap Rate (R3). R3 = (Total System Debt System Service+ Coverage x (State's Investment in the Project/State's Investment in all Power Projects))/Project Sales. R3 = ((A+ B) X (D/SUM(D))/E 4. Determine whether the Without Cap Rate for each Project exceeds the Slstem Cap Rate and if it does, set that Project's Debt Service Rate R4) equal to the System Cap Rate. . 1 If R3 greater than.R2 then R4 = R2 5. If any projects are capped then using these rates would result in a shortfall of funds to meet debt service obligation. In order to correct this, the debt service share (and thus power rates) for projects whose debt service rates are still below the cap rate, are adjusted upwards (to a maximum of the System Cap Rate). This adjustment (RS) is again based on the State's Investment in the project. RS = (State's Investment in the Project/Total State Investment in all projects whose rates are less than the System Cap Rate) x Shortfall. If a project's rate should exceed the System Cap Rate under this reallocation of the shortfall, its rate is also capped and the above procedure is repeated for the remaining projects whose rates are still less than the System Cap Rate. 6. The final debt service portion of the power rate for each project . is equal to Project's share of Total System Debt Service Costs after application of limits/Project Sales. R4 = (R2 or (R3 x RS))/E ' . APPENDIX 11 011 EFFECT OF "BLACKMAIL" CLAUSE ON POWER RATES Section 44.83 383 {b) {2) states that if the general state fund does not stand at $5 billion by July 1, 1986, the power rate for each project wi11 be set at the greater of (a) the standard HB9 rate, (b) a rate which will return 10 percent annually on the amount invested in the project, including loans and grants made by the state. A comparison of power rates under standard HB9 calculations and those under the "Blackmai1 11 clause starting in FY 1987 is presented in Table F.1. These results are also summarized for 1987 and 1991 in Table F.2. These calculations assume bond coverage of 1.10. Results The 11 8lackmail" clause, if invoked in 1987, would result in power rates increasing by more than 75 percent for Swan Lake, Tyee Lake, and Terror. Lake. The rate for Solomon Gulch would increase by approximately 30 percent. ~hese levels of rate increases would generate additional re- venues in 1987 ranging from $1.2 million for Solomon Gulch to $9.0 million for Terror Lake. Total additional revenues for 1987 would be $21.2 million. These results are itemized in Table F2. The difference between the standard HB9 rate and the "Blackmai1 11 clause rate is seen to decline over time. Since the revenue generated under the 11 8lackmail 11 clause is fixed (at 10 percent of project cost) the 11 8lackmail" clause rates will decline as sales continue to increase. For the standard HB9 rates there is a decline in rates over time for most projects but this is much less since operating costs are increasing with inflation. Table F .2 ·.
