These figures will be used to plot a graph for each reporting month. Note that when maximum dependable capacity is used for the net electrical rating of l

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 averngs daily unit power output sheet should be footnoted to explain the

apparent anomaly.
