Counsel for NRC Staff g U.S. Nuclear Regulatory Commission - @ N I o' Office of the Execurive Legal Director Washington, D. C. 20555 In the Matter of Puget Sound Power & Light Company, et al. (Skagit Nuclear Power Project, Units 1 and 2) Docket Nos. 5 0-5 22 cind 50-5 2 3 Gentlemen: For the information of the Licensing Board, the Regulatory Staff and the parties pursuant to the McGuire rule, we are enc-losing copies of the 1979 West Group Forecast (WGF). denceIton will March be recalled1, that the 1977 WGF was received in evi-1977 during the joint need for power hearing as Skagit Exhibit 87 and Pebble Springs Exhibit 26 (Tr. NFP 1760). Subsequently, the 1978 WGF was distributed to the Board, the Regulatory Staff and the parties under cover of our letter of March 4, 1978. Forecasts, To facilitate comparison of the 1977, 1978 and 1979 West Group we are also enclosing a graph on which we have plotted the energy deficits projected in each of these forecasts. (The values plotted are from line 10 of the estimated loads and resourcer tables, copies of which are attached to the graph.) The graph also shows the probable energy dates (projected on-line dates) for Skagit Unit 1 (S1) and Skagit Unit 2 (S2) used i. the 1977 WGF as well as those used in the 1979 WGF. 2'82 001 7 906 :2 0 /R2
Valentine B. Deale, Chairman Richard L. Black, Esq. May 4, 1979 Page Two As can be seen from the graph, the projected energy deficits facing the region during the mid-1980's have become progressively more alarming with each new forecast. The reason is apparent from the tables, which show that, although estimated loads have been reduced, this has been more than offset by delays in the addition of new resources. With specific reference to the WGF projected need for the Skagit Units, the following table compares the projected energy deficit for the year of initial operation of each unit as shown in the 1977 WGF with that shown in the 1979 WGF, Skagit 1 Skagit 2 1977 WGF 84-85 (1108) 86-87 (290) 1979 WGF 86-87 (1159) 88-89 (1033) As can be seen, the projected need for Unit 1 -- the energy deficit facing the region with the unit on-line -- during the first year of its scheduled operation remains about the same under the 1979 fore-cast as it was under the 1977 forecast. The projected need for Unit 2 during its first year has become more pronounced. Very truly yours, PERKINS, COIE, STONE, OLSEN & WILLIAMS

Mr. Howard C. Elmore March 30, 1979 Page 2 Tailwater constraints have been imposed on operations at Grand Coulee which reduce the peaking capability for years 1980 through 1983. In order to reflect this condition an adjustment of 1,543 mw has been deducted in this year's report in the first four (4) years. Again this year, a range of projected loads was made from the econometric model developed for PNUCC by National Economic Research Associates. This model produces a spectrum of possible loads, providing one (but not the only) comparison for checking the reasonableness of the actual load forecast which is contained in the West Group Forecast.

I . DEFINITIONS For the purpose of assisting in interpreting the enclosed figures, the following terms are explained: Critical Period: The multimonth period during which the least amount of firm energy load can be served from firm resources. With the scheduled development of additional storage facilities, both U.S. and Canadian, the critical period has extended to a multiple-year sequence of historical water years. For the load years included in this report, the length of the critical period based on 1928-32 water years is 42 months (August 16 through February 29) for the first eight years of the report and 43 months (September 1 through March 31) for the last three years. The hydro peak capabilities are the January peaking capa-bilities based on 1936-37 s treamflos conditions. The 1936-37 water year represents the most severe conditions that would cccur in a single season with reservoirs full at the beginning of the storage drawdown period. Adverse Water Years: Historical water years during which the critical period occurred. Firm Resources: (Firm Power and Energy Capability) - Peak and energy resources of all systems, plants and reservoirs when operated as an integrated unit and when related to the characteristics of the Area firm load and as limited by the regulated streamflow of the critical period of the adverse water years. Milestone: A significant event in the critical path from conception of a thermal project to the time it is placed in commercial operation. Once construction is started, the Milestones are represented by a continuous curve relating percentage of com-pletion to the date of commercial operation. Probable Enerav Date: The later of the scheduled date for commercial operation as submitted by the plant sponsor or the date deter-mined by application of Milestones. Secondary Resources: Resources in excess of firm resources. Total Load: The peak and energy load that the West Group Area plans to provide resources to serve. The Area load consists of two components which are: (1) Firm load or the load which a utility or agency is committed to supply. (2) Interruptible load or the load which by agreement can be cur-tailed due to adverse water or shortage of machine capacity. 2282 013

WEST GROUP FORECAST Discussion of Detailed Report Ob jectives The West Group Forecast is an area report prepared annually by the loads and Resources Subcommittee of the Pacific Northwest Utilities Conf erence Committee. Its objective is to show the estimated peak and energy loads and the peak and energy capabilities of existing and planned resources to meet these requirements. The basic criteria employed in the preparation of the report are described in the following text. Details of estimated loads and resources for the period July 1979 through June 1990 are tabulated in the report. Comparisons of total peak and energy loads with peak and energy resources indicate when deficiencies or surpluses may be expected in the area under adverse streamflow conditions. The probabilities of failing to meet area energy loads are determined for each year. The critical-period hydro energy capabilities have been predicated on coordinated operation of all West Group resources, including the operation of Canadian Storage, as required by the Pacific Northwest Coordination Agreement. In preparing the analy-sis, an attempt was made to shape any surplus or deficiency as uniformly as possible during the critical period. Tabulations " Summary of Resources" include the energy capabil-ity and January peak capability for each of the contract years (July through June) of the report period. Summary tabulations by months for 40 years of water record showing the surpluses over the firm energy load carrying capability are also included. A more detailed analysis of individual plant January peak capabilities and critical-period energy capabilities is tabulated in Section V, " Peak and Energy Capab ility". Operating Area Covered The report area includes the entire state of Washington, the panhandle of Idaho, Oregon except for the southeastern part of the state, a portion of northern California, the Bonneville Power Administration and Pacific Power & Light Company service areas in Montana, and the BPA loads and USBR resources in southern Idaho. It does not include' the service areas of Idaho Power Company, Utah Power & Light Company, The >bntana Power Company, California-Pacific Utilities Company, B.C. Hydro and Power Authority or West Kootenay Powe r and Light Company , Limited . Firm contractual arrangements of utilities operating in the Wes t Group Area with utilities outside this area have been included in sumnary tabulations. 2282 018
Planning Es timates The West Group Area loads used for planning purposes are the sum of the system peak loads and the system energy loads estimated by each of the utilities operating in the area. The resulting total average annual rate of load growth for the area for the 10-year period is approximately 4.1% peak and 3.9% energy. The estimates include an increase in total'BPA industrial load, due to technological changes, of approximately 40 megawatts per year. Despite the reduced load estimate appearing in this year's West Group Forecast, energy deficiencies occur in every year through 1939-90. The total West Group peak and energy loads by months are found in Section VII of the report. Section VII also includes a bu akdown of loads by major utilities. The utilities are keenly aware of the need for accurate load forecasts in the planning and scheduling of resources to meet the projected power requirements. The costs and difficulties of acquiring capital are at historic peaks, and the utility industry is very capital intensive. Therefore, scheduling of resources in advance of need could result in an adverse financial impact on utilities and their cus tomers. Conversely, there would be severe adverse economic ef fects on the people and commerce of this area and a difficult allocation er rationing problem for state govern-ments if there were insufficient resources to meet the power needs. Because of the vital importance of balancing the loads and resources, the load-resource analyses are reviewed at least annually. If experience shows that more than enough resources have been scheduled, the schedules can be corrected by delaying completion; but if too few resources have been scheduled, there may be no way to avoid the public injury from the resulting shortage. The BPA system load excludes Grand Coulee and Roza pumping loads and USBR local use at Grand Coulee, and compensation for these loads is accomplished by reducing Grand Coulee and Roza resources by equivalent amounts. The Forecast reflects plans to provide resources to serve both the peak and energy components of the total Bonneville Power Administration industrial loads, approximately 25% of which may be interrupted for any reason. The BPA interruptible load has been noted in Section VII on the sheet "Information on Loads", and is shown on line 11 in Section I on the summary sheet "Es t imated Loads and Re sources" . These loads operate under contracts which 1 Pending BPA's dev -lopment and adoption of an allocation formula, BPA has not determined that it will serve either the present or new loads of its existing industrial customers after their existing contracts expire. This statement applies to all places in this report that include or make reference to BPA's industrial loads. 2282 019
do not assure a firm power supply; therefore, it is to be expected that these loads might be curtailed if necessary curing an adverse water year. Peak load estimates are based on 60-minute clock-hcur averages. Within the hour, short-time loads vill be in excess of the hourly average. However, peak load diversities between systems result in an area peak lower than the sum of system peaks. The short-time peak loads in excess of the hourly average and the diversity in system peak loads are of the same general magnitude and tend to cancel each other. Energy loads on the summary sheets are shown as a July-June average. Econometric Model Es timates During the last three years the PNUCC has utilized an econo-metric load forecasting model to forecast West Group loads for the purpose of checking the reasonableness of the forecast of West Group Area loads prepared by the area utilities. The model was originally developed by a nationally recognized consulting firm and provided to the PNUCC in January 1976. Since that t ime , the Model Review Subcommittee of Task Force 6 of the PNUCC has continued to maintain a current data base and deselop the model to improve its forecasting capabilities. The PNUCC model, as with any econometric model, attempts to quantify relationships between electric energy demand and various causal factors. These relationships are developed through statis-tical analysis of historical data. The model handles each of the three major load classifications (namely, residential, commercial and industrial) separately. The residential sector is disaggregated to consider the saturation levels of various energy end uses. Within the industrial sector, ten industry types are separately forecast. The PNUCC econometric model is a valuable tool for analyzing Wes t Group Area loads for several reasons. Fi rs t is its ability to explicitly handle price and income ef fects. With the recent dramatic increases in energy prices and expected future increases, it is particularly important to quantify their impact on electric loads. Second is its ability to accept forecasts of demographic and economic factors, such as population and employment, thus providing some consistency between regional forecasts of these factors. Third, this is the only model availab1' which covers the entire Wes t Group Area. Finally, given a set of input values. the model will always produce the same results. This f acilitates testing the sensitivity of forecasted loads to changes in ir. guts or model structure without being influenced by prejudices of the person running the =odel. Howeve r , che model has limitations which must be considered when interpreting results. The model's results are dependent on _3 2282 020
forecasts of population; f amily income; employment; prices of oil, gas at.d electricity; and so on. Even if the model perfectly simulated the historical relationships between these f actors and electric loads, the projected loads could be no better than the forecasts of these factors. In an effort to improve the accuracy of these forecasts, the input values for this year's forecast were prepared during a two-day workshop. The intent of the workshop was to bring together individuals representing a broad range of backgrounds and interests who could provide their expectations concerning the economic and political factors affecting the input values. Half of the nearly 70 participants were nominated by the States of Idaho, Oregon and Wash.ngton and represented various state agencies, and environmental and consumer groups. The remaining participants were members of the PNUCC's Task Force 6. Inputs addressed in the workshop were oil prices, gas prices, conservation, per capita income, population and persons per house-hold, and solar energy savings. A separate session was held for each input during which two or more experts presented background information on the input and their views of the future input values. Time was provided for the participants to ask questions, discuss the presentations and present their own views. Following each session, each participant was asked to forecast values of the inputs. Fo r mo s t inputs three values were required: a most probable, a reasonable low, and a reasonable high. The reasonable low and reasonable high values were to represent a 90 percent confidence level. These values were entered into the model's data base for use in forecasting electric sales. The scenario results of the most probable, reasonable low, and reasonable high votes will be included in the documentation. An advantage of selecting input values with this procedure is that it incorporates the judgement of a large number of individuals including minority opinions. The workshop also was useful in bringing together individuals f rom various groups involved in energy forecasting to share views on important input values. A computer program was used to randomly draw one value for each of the most probable inputs with each participant's choice having an equal probability of being drawn. The model was then solved using these values and the results recorded as one possible future. The process was repeated 500 times to produce a distribu-tion of future electric loads resulting from the randomly selected input values. The average of the 500 forecasted annual energy growth rates during the period July 1979 through June 1900 is 3.9 percent. The 90-percent confidence band of the f orecasted annual growth rates provides a range from a low of 3.0 percent to a high of 4.3 percent. This large range of growth rates produced by the econometric model indicates the uncertainty in forecasting electric loads. __ ?282 021
The fact that both the West Group Forecast and the average of the 500 econo tetric model runs resulted in an annual growth rate of 3.9 percent cannot be construed as indicating precision in forecast-ing. If any of the input values to the econometric model were changed, the average of the 500 runs could have been different, but would likely have f allen within the 3.0 to 4.8 percent range. Further, econometric models assume that responses to economic conditions will be the same in the future as they have been in the past and that no changes in technology, governmental regulation or international politics will occur * ; upset the validity of the model. For these reasons, an econometric model provides a valuable tool for analyses but cannot be expected to provide a precise forecast of future growth or even predict a narrow band of possible growth projections with a high degree of confidence. A complete description of the model and the model results are contained in a report prepared by the Model Review Subcommittee. New Resources New hydro projects included in the determination of the January peak and firm energy capabilities in the report are those considered to be assured. All federal projects included are authorized projects which are under construction or have been funded for construction or preconstruction planning. Nonfederal hydro projects include additional capability at High Ros s . A license application has been issued by the Federal Energy Regulatory Commission (now pending before the U.S. Circuit Court of Appeals) to raise the height of Ross Dam to a new lake elevation of 1725 feet over the present lake elevation of 1602.5 feet. The energy resources include the generation in the United States resulting from the storage regulation of the three Canadian reservoirs (Duncan, Arrow, and Mica) in ccordination with the Libby reservoir and other power facilities in the West Group Area. No adjustments were made in downstream project power capabilities for the return of Canadian Entitlement to Canada inasmuch as the power has been purchased on a long-term basis by utilities in the Pacific Northwes t. This year's report assumes Libby generation will be reduced in 1984 due to water being diverted f rom the Kootenay River to the Columbia River at Canal Flats in Canada. The new projects scheduled as part of the area's resources plan for meeting loads through 1989-90 are listed in Section II, and a chronological tabulation of the expected cumulative hydro nameplate ratings is given in Section IV. Section II also includes an enumeration of the various hydro projects which are under consideration in this area but were no t included in the calculations. 2282 022 New thermal plants included in this year's report are those for which siting certificate applications have been made and the Pacific Northwest Utilities Conference Committee considers essential if the area's load requirements are to be met through the year 1989-90. The new thermal projects include some f rom which only part is scheduled as a West Group resource in meeting load require-ments. These include 60 percent of Colstrip Units #3 and #4 and 90 percent of Boardman. Pacific Power & Light Company's (PP&L) 66-2/3 percent share of Jim Bridger plant continues to be available to serve West Group loads for a number of years; however, because of the delay in the receipt of all permits necessary to construct the Midpoint-Malin 500-kv transmission line providing additional transmission capacity between Wyoming and the West Group, the amount of power and energy available from Wyoming has been reduced by the amount bo ttlenecked in Wyoming. This is reflected in the imports from Eas t Group u;i' 4 rtes along with PP&L's surplus Wyoming system generation after meeting Wyoming's firm loads. The ."ddpoint-Malin line is assumed operational in September 1981. The energy capabilities of large new thermal resources (500 megawatts or larger), are computed on an annual plant factor increasing from 60% for the first full year of operation to 75% for all years thereaf ter. The plant factors include allowance for scheduled maintenance outages. PNUCC Task Forces are continuing evaluation of appropriate plant f actors for planning. The scheduled dates of new thermal resources as shown in Section II are as submitted by the project sponsors; however, the peak and energy capabilities from such plants are based on the
" Probable Energy Date" as later described in the text. The " Summary of Resources" tables in Section III show zeros in the intervening periods.
For new thermal plants under 500 megawatts, the energy capabili-ties used are those submitted by the plant construction agent. This year's report shows all thermal energy generation as a July-June average. The impact of the second Bacon siphon and tunnel for the Bureau of Reclamation's Columbia Basin Project is not reflected in this year's report. Negotiations with the water users have not reached a point where realistic estimates of increased pumping can be made. Any changes are expected to be gradual. Joint Area Planning The Pacific Northwest's publicly- and cooperatively-owned systems , investor-owned ut ilities , BPA and the Corps of Engineers have historically cooperated in informal, long-range planning with respect to future regional power requirements. BPA's participation in regional programs, together with other alternatives, has been considered in a "Draf t" Role Environmental Impac t Statement that is now being put in a final form. BPA is also developing a policy 2282 023
for allocating its power supply amongst its existing customers and competing bids from potential new customers. There is proposed legislation before the Congress that could have a substantial impact on regional power planning. The scheduled dates for commercial operation of the new thermal facilities are the dates determined by the sponsoring utility for each plant. Experience throughout the United States has conclusively demonstrated in the last few years that many more large thermal plants are delayed beyond their scheduled completion dates than are completed on time. The reasons are many and may be caused by delays at any point along the paths of their respective development programs. Which plants may be delayed and for what reason or for how long cannot be anticipated in advance. Yet, on the average they will be delayed; and if the area were relying on firm resources based on every project being completed on its scheduled commercial operation date, the area's planned capacity and energy would not be realized. It is important that the area's indicated resources realisti-cally reflect the energy and capacity which can be expected on the average, recognizing that some of the scheduled completion dates will not be met. The capacity and energy resources in this report are therefore based on a Probable Energy Date which is the later of the Scheduled Operation Date or the Milestone Date. Milestones Milestone dates are detennined from a standardized schedule reflecting anticipated average planning and construction times. The Milestones provide a means for utilizing a standardized schedule without upsetting the developmental program of each project planned by its sponsor. It is considered essential that each sponsor vigorously pursue his planned schedule in order that the area's planned levels of energy and capacity can be achieved despite the inevitable delays at some projects. The Milestones are designed to reflect possible plant delays in excese of those considered in the scheduled Commercial Operation Dates. The causes for these delays include many which are not under the control of the building agency or utility. These include litigation and ever-changing procedures affecting site approvals, cons truction permits , and licensing. It is not anticipated that they will occur at each plant, but rather that the delays will be greater at some and less at others, with the consequence that the region's energy and' capacity resources will be properly estimated by applying an average delay to each plant. Milestones are reviewed each year and modified whenever required by changed conditions. More lead-time is required for a thermal plant in Oregon than in the other states of the West Group Area because a 120-day notice of intent is required before the application for site certification is filed. The Oregon Facilities Siting Council is then allowed two years for a decision. 2282 024
A project sponsor may select a schedule of greater duration than that indicated by the Milestones, and it is assumed that where this is done the schedule of activities leading to the indicated date for commercial operation is such that the scheduled date is the most probable date. A tabulation is included which compares thermal plant schedules as submitted by project sponsors and the Probable Energy Date. Charts showing the Milestones for both coal-fired and nuclear plants are also included at the end of this sectinm Present Re sources Present resources include all generating resources presently available within the area. Small fossil-fuel plants and combustion turbines have been included as firm resources in the amounts submitted by each of the project owners. Where these plants are included as peaking resources and the firm energy included is the amount associated with such peaking operations, the remaining energy capability is considered available for energy reserves. However, these are petroleum-fueled plants utilizing high-cost fuels of questionable availability. The Hanford-NPR project has been included as a firm energy resource through June 1933. Due to its frequent refueling cycle, the project is not considered dependable as a peak resource, and is, therefore, not included as such. All existing thermal plants regardless of size have been included as firm resources in the amounts submitted by the plant operator. Interchanges With Systems Outside the Area The resources include firm arrangements for interchanges with systems outside the reporting area. These arrangements (excluding PP&L's Wyoming transfers) are firm contracts with utilities to the Ea s t , Canada, assignment of Canadian Entitlement Exchange Powe r to the State of California, deliveries of power to the Central Valley Proj e ct , and capacity sales and exchanges with California utilitiet. Transfers to the Pacific Southwest are amounts delivered to the California-Oregon border. The incremental losses to the border associated with deliveries to Central Valley Project, Canadian Entitlement Assignment and peak / energy exchanges are shown on the "Scamary of Resources" sheets. These losses were deducted in determining the amount of peak and energy available to meet area requirements. Further breakdowns on interchanges with systems outside the area are tabulated in Section VI to permit users to more readily assess the effect of these transactions on area requirements. All energy transfers have been included as a July-June average. _s_ 2282 025
Reservoir Operation A comprehensive analysis of monthly secondary energy using historical flows of record was made for all load years. Through this type of studies it is possible to analyze area resources and study reservoir regulations that would occur for all water years including those with minimum runof f and those with ext remely high runoff. In making these analyses, procedures as developed undar the Pacific Northwest Coordination Agreement were followed. In computing the critical-period energy capability, all reservoirs in operation prior to the beginning of the operating year being studied were assumed to be full at the beginning of the storage control period and draf ted to their normal bottom elevation by the end of the critical period to produce maximum firm energy and establish critical rule curves. This maximum firm energy becomes the Firm Energy Load Carrying Capability (FELCC) of the system. The 40-year studies assumed that all reservoirs were full at the beginning of the first year of the 40-year pariod. Reservoirs were drafted to energy content curves except uhen draf ts below energy content curves were needed to carry FELCC. When draft below energy content curve was required, an attempt was made to draft all reservoirs a proportionate amount between energy content curves and critical rule curves. The energy content curves were adjusted in each month from January to April on the basis of subsequent runoff during that year to produce the maximum amount of secondary energy censistent with the requirements for refilling the reservoirs. In addition, flood control requirements developed by the U. S. Corps of Engineers for each of the major reservoirs were considered as a mandatory draf t whenever the energy content curve was above the flood control requirement. Where reservoirs h ve restrictions on their operation for power productic those restrictions were observed in setting up the draft scheduies in these analyses. Restriction o,n Usability of Resources The Uniform Regional Planning Assumptions adopted by the PNUCC state that each 'ystem will take into account the ability of hydro generation to achieve claimed capability. Under this crite-rion BPA last year submitted a 5 percent realization factor nn the January peak capability of the Federal system. This f actor was an adjustment representing the reduction in capacity which would result in actual operation from inability to maintain all pools at their optimum levels from environmental restrictions, etc. This year the Federal System realization f actor concept has been modified to re flect its inability to maintain generating capabilities equal to load requirements over the extended 6- to 10-hour heavy-load periods. An adjus tment amount has been deter-mined by which the total Federal 1-hour peak value has been reduced to obtain the to*al Federal sustained peak value for each January. In addition to the reduction for sustained peak, tailwater constraints have been imposed on operations at Grand Coulee which reduce the peaking capability for years 1980 through 1983. In order to re flect this condition, an adjus tment amount of 1,54 , megawatts has been deducted in this year's report in the first 4 years. Thus, this year a Federal peak adjus tment value (hydro realiza-tion factor) is shown which is the total of these two amounts and varies f rom 3,963 megawatts in January 1930 to 2,590 megawatte in January 1990. Consequently, the Total Peak Resources shown on the summary sheet in Section I have been reduced by these amounts. Hydro energy capabilities have not been reduced to reflect energy loss due to spill and discharge requirements f or downstream fish migration. Except for the bottleneck in transferring PPSL's Wyoming resources to the West Group, it has been assumed that there will be no restrictions on the utilization of all the availtble resources because of bot tlenecking transmission lines, trans formers, e tc. , or because of reactive loading of generating facilities. Scheduled .'bintenance In order to provide an indication of the maintenance normally undertaken in the Pool, we have included estimated amounts for scheduled maintenance in derivation of energy capabilities. These amounts are shown on tabulations " Summary of Resources". The acounts of maintenance for hydro and existing small theraal resources are based on a procedure developed by the Coordinating Group of the Northwest Power Pool and utilize a percentage of energy capabil-ities by months. The hydro maintenance used in the derivation of January peak capabilities is included as part of the reserves used in this report which were determined by the percentage method. Reserve Requirements In the derivation of January peak capabilities, reserves have L e. deducted from the tabulation of peak resources. The area peak reser/es used are the greater of (1) f orced-outage reserves as computed under the Pacific !brthwest Coordination Agreement plus one-half year's load growth for utility-type loads plus hyd ro maintenance or (ii) 12% reserve for the first year of the study, increasing 1% per year to 20% and ramaining at 20% thereafter. The reserve requirements are shown in Section I on the summary sheet "Es timated Loads and Re sources" . 2282 027 The percentage nethod has been the controlling f actor for the month of January oetween these two methods since they were initiated in 1974 and is used in this report. These reserves are used primarily for long-range planning and take into account forced-outage reserves, hydro maintenance, unanticipated load growth, project construction delays, and other contingency-type reserves. The percentage reserve method was a consensus of the representatives of PNUCC members to reflect peaking requirements, taking into account that new resource con-s truction may take up to ten to twelve years and that a project may be delayed much more easily than it can be accelerated. The area energy reserves shown in Section I on the summary sheet are one-half year's load growth for utility-type loads. Ene rgy Reserve Planning Model The Energy Reserve Planning Fbdel was developed to provide an improved method for analyzing the load-resource relationship in a hydro-based system increasingly dependent on thermal generating facilities. Our traditional techniques have combined an extremely comprehensive treatment of hydro energy capabilities with a single-
'alued estimate of thermal energy generation, and they have only partially reflected the responses of operating policies to system conditions. So long as the proportion of thermal energy generation in the system was quite small, these established methods were adequate.
In the future, however, the reliability of energy supply will be af fected not only by the vagaries of hydro runof f, but also by the uncertainties of thermal plant construction and availability once in service. These plants individually represent large portions of the total energy supply, and their lead-times, at best, are very long. A single plant's delay in construction or poor perfor-mance af ter completion might have a profound impact on system reliability, which cannot be measured in an analysis where the plant is represented as having a single probable installation date and a single average capacity factor. Along with the uncertainties of hydro and thermal energy capab ili tie s , the wide range of possible energy loads on the system in future years contributes to the doubts about the suffi-ciency of reliability evaluations based on single-point estimates. The >bdel is a probabilistic simulation program, designed to treat rigorously the four general components of the energy load-resource p icture--hyd ro, thermal plant construction, thermal plant availability, and load--combined with logic which operates the system model realistically in response to simulated conditions of these components. Ic is based on a modelling technique called Monte Ca rlo Simulation, in which statistical results are derived from a mass of repeated trials. Within each trial, the model 2282 023
system is operated into the future continuously, and the state of each variable in each time interval is determined by a random draw from an appropriate probability distribution. Each trial, therefore, represents a possible real outcome, but many trials are necessary before a statistically valid conclusion can be drawn about the future. The probabilities shown in this report are based on a study comprising 2,000 trials. At the beginning of each trial, storage contents are defined on the basis of the latest available forecast at the time of the study.
.The representation of energy load in the program presently has no probabilistic features; a list of load forecasts is input and used as fixed quantities. Work is continuing on logic which will treat the forecasted loads as a trend about which yearly deviations will be randomly generated.
As it stands, the Energy Reserve Planning Model is believed to be a significant advance in the state of the techniques available to analyze the energy load-resource situation. But it is not a finished product, nor will it ever be. Efforts to improve its structure and data will be continuous, and frequent program changes are expected. The probabilities of the resources being insufficient to meet the total energy loads during each year of the forecast period and cumulatively through the forecast period are shown on lines 13 and 14 of the preceding tabulation of loads and resources. The proba-bilities of an insufficiency increase to a maximum of 50.7 percent in the year 1983-84 and continue at a very high level throughout the forecast period. The cumulative probabilities of insufficiency show that there is a 92 percent probability of insufficiency prior to 1984-85 and a 98.9 percent probability that an insufficiency will occur during the forecast period. The corresponding figures for resources being insufficient to meet firm energy load are shown on lines :5 and 16. They reach a maximum of 27.8 percent in 1983-84 and incicate an 85 percent probability of insuf ficiency sometime during the forecast period.
