Please see the post-outage recommissioning planned profile below (please scroll to the bottom of the post).  Availability is reduced from 425MW to the planned profile. It must be noted that the planned profile will not change throughout the day of testing, but will be subject to variability, with an increased likelihood of a trip event.  However, significant deviations to the Day 2 recommissioning, which is expected to run between 26/10/2015 06:00 and 26/10/2015 13:00, will be commented on.
