On this form list the average daily unit power level in MWe-Net for each day in the reporting month. Compute'to the nearest whole megawatt. These figures I will be used to plot a graph for each reporting month. Note that when maximum- I dependable capacity is used for the net electrical rating of the unit there may j 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.
