Dear Board Members:
This letter is to update certain projected load and capacity estimates which appear in the record of this proceeding, pursuant to Applicant's obligation to keep the Board appraised of such : natters under Duke Power Company (William B. McGuire Nuclear Station, Units 1 and 2), ALAB-143, 6 AEC 623 (1973).
This information is relevant to Intervenor's Contention 2(c) which challenges the need for continued opera-tion of Zion Station.
The Licensing Board's discussion of Contention 2 (c) appears at 11 NRC 245, 253-256.
The Licensing Board's findings on this issue have not been aopealed, but out of perhaps an excess of caution, we forwaro this informa-tion to you anyway so that the record will be complete.
In June, 1980, Commonwealth Edison announced delays in the construction of its LaSalle, Byron and Braidwood units.
(Attachment A)
In addition, projected demand has been reduced from a ten-year compound average rate of increase I'
l 800'7300
Atomic Safety and Licensing Appeal Board July 8, 1980 Page Two of 4.5% to a tea-year compound average rate of 4%, with even lower growth in demand fer electricity occuring in 1980 and 1981.
The net effect of these two changes is to increase the need for continued operation of Zion Station, which can be seen by comparing Attachment B with the peak load reserve levels which appear at 11 NRC 245, 255.

Commonwealth Edison Company submits for your information the following update of scheduled commercial service' dates for the subject units.
In addition, the purpose of this letter is to clearly define our present expectations relative to the licensing review schedule for these units and to document our scheduled' operating license (fuel load) dates.
The schedule commercial service dates set forth below reflect delays recently announced by the Company due to con-struction difficulties and to spread ~inancing requirements more evenly through the five jcar construction program in order to keep annual financing requirements within the Company's financial capabilities.
They also reflect delays announced last year as a result of changes in the Nuclear Regulatory Commission's licensing schedules recommended by the Office of Nuclear Reactor Regulation of the MRC as a result of transfers of staff resources from licensing to the investigation of the Three Mile Island incident.
The scheduled service' dates set forth for the LaSalle County units also reflect delays announced last year resulting from construction changes, including re-visions in the design of the containments.

'8 Fuel Load July '80 It is acknowledged that in the case of LaSalle County Unit 1 the scheduled fuel load date i6entified by the NRC Staff is two months later than that indicated by the applicant.
However, it is judged that these dates are so close that the difference is inconsequential for the purpose of seneduling both your resources as well as our own.
In addition, from the standpoint of efficient utilization of engineers at both Commonwealth Edison and the NRC it is important that the licensing process for both Byron and Braidwood proceed concurrently, as it
- has, You may expect our full cooperation and presentation of documents which should~ help you conduct the necessary reviews at LaSalle County, Byron and Braidwood Stations.
Should you have any questions please call or write this office.
