      The unavailabilities planning of a production unit is EDF’s best estimate at the time of publication and it is based on an estimate of the duration reasonably required for the planned works or events liable to affect the asset. In case of overlapping outages, whether forced or planned, the practice is to use the lowest available power for each overlapping period.
