Compute to the nearest whole megawatt.

These figures will be used to plot a graph for each reporting r th. Note I that.when maximum dependable capacity is used for the net elect. al 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.
