Compute to the nearest whole megawatt.
These figures will be used to plot a graph for each reporting month. Note that by using maximum dependable capacity 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.
