! In the Matter of Puget Sound Pcwer & Light Co,apany, et a l ._

(Skagit Nuclear Pcwer Project, Units 1 and 2)

Docket Nos. 50-_522 and 50-323 Gentlemen:

For the informatian of the Licensing Board, the Regulatory Staff and the parties pursuant to the McGuitj rule, we are enclosing copies of the load forecasts of the four co-owners of

, the Skagit Project as recently updated for use in preparing the 1979 West Group Forecast (WGF) .

)

To facilitate comparison of these load forecasts with those

! introduced in evidcnce at the joint need for power hearing in March 1977, they have been prepcred in the form of updated

- Tables A, B, C and D , which may be compared with Tables A, B, C j~ and D attached to the testimony of David H. Knight dated Feb-

. ruary 15, 1977 (follows Tr. NFP 3527, March 9, 1977). To be consistent with the prior tables, the updeted loads shown for Pacific Power & Light Company are its total loads and thus include its Wyoming loads, which are not part of the West Group.

We are also enclosing an updated Table E, the four-cccpany composite, which may be compared with Table E attached to Knight's testimony.

Additionally, we are cnclosing updated versions of Tables H, I, J and K attached to Knight's cited testimony, which show the actual loads of the four co-owners through the end of 1978. It should be noted that these are system leads not total loads.

~i .

The currently estimated resources of the four participants are also shoan en the enclosed Tables A, B, C and D, which separately list the estirated contributions of the two Skagit units and the two Pebble Springs units to the resources of the respective participants in those two projects based on the currently estimated " probable energy date" for each unit, i.e.,

the later of the WGF rilestone date or the scheduled completion date. The current probable energy dates, which vill be used in the 1979 WGF, are as follows:

1979 WGF l_977 WGF 5%agit Unit 1 November 1986 August 1984 Skagit Unit 2 Novecabe r 1988 August 1986

Pebble Springs Unit 1 March 1987 July 1985 Pebble Springs Unit 2 April 1989 July 1988 For comparison, we have also listed the probable energy dates ,

-'t were used in preparing the 1977 WGF and the tables that

+". presented at the March 1977 joint hearing on need for power. The current dates reflect the licensing delays that

> have ,ccurred since that time. In the case of the Skagit

! units, the current dates are based on the assumption that the LWA or construction permits will be issued by Septerber 1979.

In the case of the Pebble Springs units, the current dates are based on the assun.ption that both the state certification and the NRC construction permits will be issued by January 1930.

In response to Mr. Linenberger's request at the recent conference, and to facilitate comparison of the enclosed 1979 forecasts with the 1977 forecasts that were presented at the March 1977 joint session, we are enclosing updated versions of Figure . end Table 1. The initial versions of Figure 1 and Table 1 cons tituted pages 10 and 11 of Applicants' Answer of May 5, 1978 to last year's FOB /CFSP Motion for Reopened Need

i f a i'

i Valentine B. Deale Richard L. Black January 25, 1979 Page 3 for Power Evidentiary Record, which was denied by the Bcard's Order of May 18, 1978. To the initial version of Figure 1 we q have added the 1979 four-co:apany composite forecast from the enclosed Table E dated January 22, 1979. As can be seen, the curve for the 1979 forecast is essentially the same shape as the curve for the 1977 forecast--but it has shifted to the right and also shows a larger deficit. What this demonstrates is that the projected need for the Skagit units is now more pronounced than the existing evidentiary record--the 1977 forecast--would indicate. .

Table 1, to which we have added the 1979 forecast, shows in more detail that the currently projected need for the Skagit units is somewhat greater than that shown by the 1977 forecast. This can be seen by comparing the magnitudes of the projected deficiencies under the two forecasts, if either of the Skagit units were not to come on-line when scheduled.

(Col. C. vs. Col. F. ) Under the 1977 forecast, in which Unit 1 was scheduled to come on-line in 1984-S5 (Col . B for 1984-85, 708 MW), the projected deficiency for that year withou'c Unit I was 1407 K4 (Col. C for 1984-85). Under the 19'4 forecast, in which Unit 1 is scheduled to come on-line in 1986-87 (Col . E I for'1986-87, 515 MW), the projected deficiency for that year without Unit 1 is 1575 K3 (Col . F for 1986-87). With respect to Unit 2, tl.e cc:aparable projected deficiencies under the 1977 and 1979 forecasts are the same--615 MW--if Unit 2 were not to come on-line whcn scheduled.

Very truly yours, PE2 KINS, COIE, STONE, .
