• These figures will be used to plot a graph for each reporting mon.th. Note that by using maximum dependable capacity for the net electdcal rating of the unit, there. may be* occasions when the daily average power level exceeds the 100% line (or the restricted power level line). In such cases, the.

average daily unit power output sheet should be footnoted to explain the apparent anomaly.
