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 ratin; of the unit. there may be ..t easions when the daily average power level exceeds the 100'6 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.
