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 naximum 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.  ;
