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 .weasions when the daily average power level exceeds the 100To line (or the restricted power lesel line). In such c.ises. the average daily unit power output sheet should be footnoted to explain the apparent anomaly.
