. On this f 01m, 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 ior each reporting month. Note that by using rna:-:imnm dependable capacity 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 ievel iine). ln such cases, the average daily unit power output sheet should be footnoted to explain the apparer:.t anomaly ..
