On thla form list the average daily unit power level in MWe-Net'for ecch day in.the reporting month. Compute to the nearest whole megawatt. These figares will be uned to plot a graph for each reporting month. Note that when maximum dependable capacity is used for the not electrical-rating of the unit.there may be occasions when the daily average power level exceeds the 100%.11ne-(or the rest r icted power level l'ne. ). In such cases the average daily unit power-output sheet should be footnoted to explain the apparent anomaly.
