Posted for comment PRC-006-03 Automatic Underfrequency Load Shedding Regional Quebec Variance

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 45-day comment period through December 15, 2016.

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).

Also, attached are the PRC-006-3 Automatic UFLS Regional Quebec Variance Implementation Plan, HQT Letter to Waive CEAP and a comment form. Comments on the posted materials may be submitted through the NPCC Open Process Review, which may be accessed through:

Pending reconciliation of comments, the standard is scheduled to be posted for a 30-day pre-ballot review period with a subsequent ballot during the first quarter of 2017.
