Compute to the nearest wriole megawatt.

These figures will be used to plot a graph for each reporting month. Note that by using maximum dependable capacity for the net electrie.11 rating of tne unit. there may be ..t easions when the daily average power level exceeds the 1002 line (or the restricted power lesel hne). In such cases, the average daily unit power output sheet should be footnoted to explain the apparent anomaly.
