In addition to planned outages, this report reflects the repairs and maintenance being performed related to Force Majeure events.

Due to the nature of such events, the dates for the associated repairs and maintenance of those events are assumed to extend until the end of the month.

These repairs and maintenance, however, may extend beyond the end of the month including beyond the current year.

More information on these repairs and maintenance will be posted as a Critical Notice under the Notices section of the Informational Postings tab on the CIG Electronic Bulletin Board
