ATL.ANTA. GEC RGIA 3C3C 3 4o4,sazasa4 arronNns AT L&W August 2, 1979 Mr. Harold R. Denton Director, Of fice of Nuclear Reactor Regulation United States Nuclear Regulatory Commission Phillips Building Room T 202A Washington, D. C. 20555 Re: Docket Nos. 50-424 & 50-425

Dear Mr. Denton:

In connection with the current Georgia Power Company (GPC) application for a rate increase, additional information centinues to become available that is rele vant to the Nuclear Regulatory Commission (NRC) consideration of whether to re-voke the construction permit for Vogtle 1 and 2. GPC has provided a more recent projection of the capacity of the GPC system. The projection indicates somewhat greater capacity than the GPC December, 19 78 submission to the NRC. A copy of this projection is attached as Exhibit "1."

I have enclosed a copy of the recent testimony of Dr. Keewhan Choi as Exhibit "2." Dr. Choi was hired by the Georgia Public Service Commission to evaluate the method of the GPC to fore-case peak demand. Historically, Dr. Choi's forecast of future energy needs has been c loser to the mark than the Company's.

Dr. Choi estimates the growth of the annual peak demand for the next fourteen years to be approximately 3.7%. In contrast, the projection submitted to the NRC shows an average annual growth of 4.6%. By the mid-1980's, the difference in the GPC forecast and Dr. Choi's forecast is greater than the entire capacity of the two Vogtle plan'-3. For example, t- ~'C forecast of peak demand for 19 84 exceeds Dr. Choi's fore ast by 2208 MW, and the increase widens thereafter. More significantly, by Dr. Choi's fo re cas t , the Company will have a 1989 peak demand of 14,208 MN.

If the Company continues its constructicn program as planned in Exhibit "1" attached hereto , bat does not construct Vogtle 1& 2, i t w ill h ave re se rve s o f 18 ,62 7 "N o r more th an 30% reserve capacity without Vogtle. If GPC does not sell a share of Sche rer plants this reserve capacity will be even greater. Th)s 522 3n5 c'

Mr. Haroid R. Denton Page Two August 2, 1979 calculation does not include a'lowance for conservation or alternative energy systems as oatlined in the GAFE Petition of May 1, 1979.

The Company appare: ;1y recogni.zes this over-abundaI ce of generating capacity which will result from construe: tion of Vogtle. Recently disclosed letters indicate that in May, 1978, GPC sought to further reduce its share of Vogtle through sales to companies ir North Carolina, South Carolina, Kentucky and Florida. Obvi asly, GPC does not believe it need; the full output of "egtle for its customers. Copies of these letters are also attached hereto as Exhibit "3." Moreover, R. W.

Scherer, Pre sident o f the Comp any , recently testified that in 1976, Georgia Power sought to sell 90' of the output of the Vugtle plants. A transcript of this part of Mr. Scherer's testimony is not yet available.

I urge the NRC to reconsider its Apt .1 13, 1979 analysis of the GPC need for power based on the - re recent data supplied by GANE. The NRC staf f should recompute its April 13 analysis in light of Dr. Choi's forecast of peak demand and the more recent projections of capacity of the system. I believe that the conclusien of such a study will demonstrate that both Vogtle 1 or 2 are unnecessary to supply the GPC service area with adequate electricity.

Very truly yours ,

Gary Flack, Attorney for GANE GF/1 Encls.

DIRECT TESTIMO.7 OF KEEWHAN CHOI Q. Please state your name, address, and occupation. ,

A. My name is Keewi.an Choi and my address is 1122 Springdale Road N.E.,

Atlanta, CA 30306. I am a Professor of Mathematics at the Georgia State bniversity, currently on leave of absence.

Q. Please describe your educational background.

A. I received my Bachelor's degree (1953) in Mathematics from the Case Western Reserve University and both my M.A. (1960) and Ph.D. (1963) in Statistics from the Harvard University.

Q. Please describe your professional experience .

A. I taught Statistics at the Coraell Universiev (1962-1966), and at the University of Missouri (1966-1963). Since ?972, I have been teaching Statistics at the Georgia State University. I was a Research Associate in Statistics at the Atocic Bomb Casualty Commission (o'f the U. S. Acade=y of Sciences and the Japanese Depart =ent of Public Health) from 1968 to 1972. In additica to my full-ti=e teaching activities , I have served as a consultant on Statistical Methods to the Health Systems Reccarch Group at Georgia Institute of Technology, National Cancer Insri-tute and Of fice of the Secretary, Department of Health, Education, and Welfare.

Q. Have you testified in previous rate proceedings?} }io A. Yes. I testified be:are che Georgia Public Service Cct,ission in 1977 (Dackee Nc. 2002-U), under a contrac t with the Ccorgia Public

Serv ice Ccmmis sion. My testimony covered the following three areas:

1. Evaluation of the Georgia Power Ccmpany's Allocated Cost of Service Study.

2 Evaluation of the Company's forecasting method for the integrated system peak demand.

3. Evaluation of the Cocpany's revenue projection by customer class for 1977 and 1978.

Q. Picase describe the purpose of your testimony. A. My testimony das prepared under a contract with the Georgia Public Service Co= mis sion. My testimon) covers the following area:

1. Evaluation of the Georgia Power Company's forecasting =ethod for the integrated system peak demand.

Q. Picase give your evaluation of the Company's forecasting method

   \

for the integrated s, stem peak demand. A. The Company's forecasts of the annual system peak demand for years ~ 1978-1992 are not re1{able for the following 5easons:

1. Very small amount o' data (only 14 past peak demands to forecast 16 future manual peak de= ands) were used for
                             ~   '~ ~

forecasting.

2. The Company's so-callid '"we ather-normalization" process is.,
                                                                            }

logically inconsist5nt.

3. The Cocpany's econometric model for forecasting the peak demand is very unstable because of the collinearity.

Q. Please explain'the three reasons which made the Company's forecasting

                               "      ~
                                        ~

method unreliable.

                                                                                       ~

_3 A. 1. Small amount of data.

  • The Company'used only 14 pa s t (annual) peak demands to for eca s t 16 future (annual) peak demands. The decreasing certainty of the exogenous variables in the econometric codel with the increasing length of the forecasting horizon and the small a=ount of historical data compounds the fotecasting error of.the Co=pany's method. -

There is a distinct 12-month cycle of monthly peak demands, which should be utilized to obtain more accurate forecasts.

2. "'n'es ther-nor=aliza t ion" pro c e s s .

The Company's so-called " weather-norcalization" proces; to modify actual (past) peak de=cnd ia logically inconsistent. A detailed discussion of the logical inconsistency was given in N. my direct testimony before the Public Service Cocaission in 1977 (Docket No. 3002-U).1 t

3. The collinearity problem for the Co=pany's econometric codel.

The cost serious defect in the Ccapany's method of forecasting the peak de=and is in its use of two econo.uic indicators, gross state product and total personal income (which was lagged one year), to forecast the peak demand. Thos two ind ica tor s are almost perfectly correlated. The correlation coef ficient between the two indicators (which was co=puted from the 1950 to 1978 data) is .996. It is a nell-known (se istical) fact that a cultiple regression equation (which is the Company's econcmetric model) based er highly correlated 1 See Appendix 1 for a copy of the discussica. 522 ?I2

  • independent variables (two economic indicators) is very unstable.

Such a problem is called "collinearity" proLica. (See, for instance, Data Analysis and Regression by F. Mosteller and J. W. Tukey (1977) Addison Wesley). The Cenpany's peak demand forecast will change by a large amount when either one (or both) of the econcaic indicators is changed slightly. In other words, small changes in gross state prcduct or total personal income (which are forecasts the=selves) vill cause a large change in the forecasted peak de=and. The consequences of collinearity of two economic i'dicators is so severe that a si=pler cethod of forecasting the peak demand using only the gross state produce alone is core accurate than the Company's method of forecasting the peak demand using the two economic indicators A and "wcather-nor=alized" peak demand data and adjusting the forecasts for the effec.ts of air conditioner ownership, electric transportation Y and natural gas. In the following table, the actual peak de= ands for 1977 and 1978 are compared with the Cc=pany's forecasts (=ade in 1977) and the forecasts frce the simpler econometric model which uses only aros3 , , , Jdu jl) state product as an economic indicator. Actual Company The simpler Year p e a k (.'nJ ) Forecast forecast 1977 9,631 10,093 (over 4.8%) 9,297 (under 3.5*:) 1973 10,113 11,429 (o- a 13. 0~:) 10,373 (over 2.17) The simpler codel is of the same form as the Company's econemetric model, with one economic ind ic a to r . The data used for the simpler

model were the annual peak demands for the years 1950-1976. The value of R is .985 for the si=ple =cdel. Q. Has the Georgia Power Ccapany used the similar econometric model for the peak demand forecast in 1974? A. Yes, the Company used tb. similar model in 1974 to forecast annual peak demands for the years 1975 to 1983. Q. Please ccapare the Ccapany's forecasted peak demands with the actual peak demand for the years 1975 to 1978. A. The following table presents the actual peaks, the Company's 1974 forecasts (using the 1960-1974 data) and the Company's 1977 fore-asrs (using the 1963-1974 data).

In your testimony in 1977, you evaluated the Company's forecasting method and also presented your own peak 'emand forecast using the Box-Jenkin's method. How did your forecasts cocpare with the Company's forecasts? A. My forecast for the 1977 peak demand was under 2.6%, while the Company's furecast was over 4.8".. For 1978 my forecast was under 2.4%, while the Ccapany's forecast was over 13.0%. Q. What is your recommendation for forecasting the peak demand through 1992? A. I recommend that the Ccapany cake the forecasts by several dif ferent methods of forecasting, including econometcic method and Box-Jenkin's nethod, and the X-ll program by the U. S. Census Bureau. 522 314

Appendix I The following statements on the "seather normalized" load were included in my direct testimony before the Public Service Commission in 1977 (Docket No. 3002-U): l' There is a logical inconsistency in using so-called " weather-normalized" loads in the econotetric model to forecast annual peak loads. (i) For each year between 1960 and'1975, the so-called " weather-normalized" i load was obtained by adding the " residual" to a load which was obtained fro = a regression equation of the 'aily peak lead by substituting the nine year (1967-1975) average values of the four temperatures and Julian dates of the peak de=and days. Adding the " residual" to the fitted values frcs regression equ: tions invalidater the entire. theoretical basis for regression analysis. Using such " weather-normalized" loads as annual peak loads in the econometric model is devoid of any theoretical or  ; empirical justification. In the set- of regression equations, daily peak , i demand is assu=ed .to be a fu. ction o f f our te=peratures and Julian date. ' On the other hand, in the econocetric model, annual de=and is assumed to ' be a function of the Georgia State Froduct (GSP) and the Total Personal Incoce of the previous year (TPY). Absent in Exhibit 56 is any discussion o f the co=patability of the so-called " weather-normalized" loads (which vere obtained from the first set of regression equations) with r.he defini-tion of ar nual peak load in the econc=etric codel. (ii) Every one of the actual (annual) peak de= ands from 1960 to 1975 was modified to a so-called " weather-normalized" load. See Attachment 3 in Exhibit 56. This " weather ncrmalization" process i= plies that the weather conditions (temperatures / of the peak demand days hav2 been C ) ?- J c/. < .

always abnormal _ so that the peak demand for each year has to be

       =odified to obtain the " weather-nor=alized" peak demand which would have been the peak demand if the weather conditions had been normal.

In such a case, how does one estimate what would be a peak demand under nor=al weather conditions? 522 318
