Compute to the nearest whole megawatt.

These figures will be used to plot a graph for each reporting month. Note that by usmg maximum dependable capacity for the net electrical rating of the unit. there may be occasions when the daily l

average power level exceeds the 1007o line (or the re.tricted power lesel linel. In such cases, the average daily unit power output sheet should be footnoted to explain the apparent anomaly. l l
