Dear Mr. Denton:

This letter provides additional antitrust information for the Byron Generating Station.

Enclosed is one memorandum which was inadvertently omitted in the referenge (b) responses to the reference (a)

NRC questions.

Exhibit 5 of reference (b) contained copies of recent correspon-dence relating to the possible sale of electricity to other utilities.

A meeting on May 10, 1983 with representatives of Wisconsin Public Power Inc. is discussed in those documents but the meeting summary is not included.

The enclosed May 12, 1983 memorandum by Mr. Robert Beckwith was inadvertently omitted from Exhibit 5.

Please address further questions to this office.

Very truly yours,

CECO D. W. Penn R. L. Bolger E. Mullins R. Beckwith R. Philley (Atty.)

R. L. Kraatz R. G. Ferguson (IL4B) i The two parties met to discuss possible sales of power and energy ar 2

discussed in W. B. Behnke's letter of March 18, 1983 and Mr. Penn's letter et April 15, 1983.

Following is a summary of the discussion.

1.

CECO made two Eeneral proposals that might satisfy WPPI's needs:

(a) A 50 MW participation in Byron Station through 1996 at about

$20/kW-month (firm cost to be confirmed by additional study).

WPPI would receive energy at Byron cost including fuel and pro rata O&M. Any back fitting requirements would also be shared pro rata.

g/

(b) A 50 firm sale with a beginning capacity charge of about

$5/ '-month (firm charge to be confirmed by additional study) and energy charges off system margin. A summary of Edison's expected marginal costs was provided.

(c) In the above, or any other transactions, power and energy would be delivered at one of CECO's interconnection points. Any third party transmission would be arranged by WPPI.

2.

WPPI is not interested in participating in the Byron or Braidwood plants, but would consider LaSalle (See Item 5 following.)

3.

WPPI prefers a fixed capacity charge for any transaction that may be agreed upon.

4.

WPPI would be willing to consider a one-time, up-front capacity charge for any long term transaction.

5.

WPPI requested firm proposals for the following:

(a) A long-term firm sale with energy of f the system margin. In addition, the capacity charge was to be stated in terms of a one-time, up-front payment rather than as a periodic amount.

(b) A 50 MW ownership in Powerton Station allocated evenly across both units. All normal ownership obligations and benefits would accrue to WPPI.
