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 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.

INSTRUCTIONS 1 On this form list the average daily unit power level in MWe-Net for each day in the reporting month. Compute to the nearest whole megawatt. 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 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 enomaly. l (0625M/0062M-11) i N:
