Announcement Letter for PRC-006-3 UFLS Quebec Variance Pre-Ballot and Ballot Period

Please find attached clean and redlined versions of the draft NERC continent-wide PRC-006-3 Automatic Underfrequency Load Shedding Standard which has been posted for a 30-day pre-ballot review and a subsequent 10-day ballot period through March 1, 2017.

The proposed changes reflect a revision to the existing PRC-006-2 Quebec Regional Variance.

Specifically, the “Section D. Regional Variance” and “Attachment 1A” which apply only to Quebec have been revised to reflect the unique nature of the Quebec interconnection.

Additionally, the revisions were developed in accordance with the NPCC Regional Standards Process Manual and have been endorsed by the NPCC Regional Standards Committee (RSC).
