N/A INSTRUCTIONS 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 will be used to plot a graph for each reporting month.
Note that when maximum dependable capacity is used for-the net electrical 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.
