The definition of control center was expanded in version 4, seemingly to ensure that more control center’s that provide functions to different entities within each utility are required to meet the NERC CIP Standards. Essentially the standard is more specific in the definition of what types of control centers should fall within the scope of NERC CIP vs. using a more general statement as it relates to control centers. This new approach should result in the identification of potentially some new control center’s that were not previously in the scope of NERC CIP. More specifically the addition of 1.15 states that if the control center performs AGC at any generation facility, that it will be in the scope of NERC CIP.
These are some of the changes that were made
1.14 Controls center’s which are used to perform functional obligations of the Reliability Coordinator.
1.15 Controls center’s which are used to control generation at multiple plants, for any generation facility (AGC)
1.16 Controls center’s which are used to perform the functional obligations of the Transmission Operator
1.17 Controls center’s which are used to perform the functional obligations of the Balancing Authority
1.17 Controls center’s which are used to perform the functional obligations of the Balancing Authority for generation equal to or greater than an aggregate of 1500 MW in a single interconnection.
