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 elcctrital 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 apparei1t anomaly..
