+ Item No. 5:
Design Electrical Rating (DER) NET MRe has been changed effective July 1, 1991.
This reduction is the result of the steam condenser tube replacement with stainless steel tubes, which cause a
high turbine exhaust pressure.
+ Item No. 7:
Maximum dependable capacity (MDC) NET MNe, effective July 1, 1991, will be 1000, during the period from May through October and 1020 during the period from November through April.
These NET ratings and capabilities reflect historical data on generating capability due to changes in lake water temperature.
