Alignment of Ontario enforcement dates for existing and newly identified BES elements
January 21, 2016
NERC Critical Infrastructure Protection Reliability Standards Version 5 (CIP V5) introduces a new concept not included in previous versions – a BES Cyber System. A BES Cyber System consists of one or more BES Cyber Assets logically grouped to perform one or more reliability tasks for a functional entity.
The IESO will align the enforcement date(s) for existing BES elements and the enforcement date(s) for newly identified BES elements into a single, unified enforcement date for the CIP V5 standards. This will allow market participants that own or operate existing and newly identified BES elements to create the logical groupings by considering all their BES elements at the same time.
The Ontario enforcement dates for CIP V5 Reliability Standards are posted on the IESO's Reliability Standards Compliance webpage.
