- On this form, list the average daily unit power level in MWe-net for each day in the reporting month. l Compute to the nearest whole megawatt.

These figures will be used to plot a graph for each reporting month. Note that by usinf, maximum dependable capacity for the net electrical rating of the unit. there may be occasions when the daily average power level exceeds the 1007o line (or the restricted power lesel line). In such cases, the i average daily unit power output sheet shocid be footnoted to explain the apparent anomaly.
