" Item No.- 5:

Design Electrical Rating (DER) NET MWe has been changed effective July 1, 1991.

This reduction is the result of the steam condenser tube replacements with stainless steel tubes, which cause a higher turbine exhaust pressure.

" Item No. 7:

Maximum dependable capacity (MDC) NET MWe, effective July 1, 1991, will be 1060 during May through October and 1090 during November through April.

These NET ratings and capabilities reflect historical data on generating capability due to changes in lake water temperature.
