Dear Dr. Feld:
As requested during our telephone conversation of July 22, 1980, enclosed is a copy of the latest compilation of the projected loads, capacities, and re-serves for the Duke system. This tabulation reflects the long-term forecast for 1983 through 1991.
It was approved in June 1980.
I t also reflects re-vised, expected operational dates for the McGuire and Catawba units.
Please note that two types of reserve margin have been calculated.
Interrup-tible loads have been added to the total production capability to give a total reserve margin called " reserve resources."
Duke's reserve criteria may be summarized as follows:
Total Capacity required equals the sum of:
. Projected peak load,
. Addi tional load expected during extreme weather,
. Capacity of largest unit on the system, Miscellaneous capacity reductions, 5% of thermal capacity on line Capac1ty of nuclear unit (s) 1ikely to be in refueling.
The result of this calculation produces reserve levels in the 17 to 25 percent range.
A one-day-in-ten year LOLP is normally associated with a region or pool.
Duke does not have the necessary multi-area reliability assessment program to calcu-late the reliability of interconnected systems. However, we have used a single-area reliability assessment program to estimate the contribution of intercon-nections to our system reliability.
This study indicated a reserve of 38 per-cent'would be necessary to maintain an average LOLP of one day in ten years for the next ten years.
Sool As requested, we a'so offer the following information:
