Reliability-based Control (Project 2007-18)

Registered Ballot Body | Related Files | Reliability Standards Home Page | Drafting Team Rosters

Status
The Standards Committee authorized moving the Reliability-based Control SAR forward to standard drafting.

Purpose/Industry Need 
This project includes expanding on the work already done in developing the draft BAL-007 through BAL-011 by adding requirements to address the following concerns:

• To support corrective action by the BA when excessive Area Control Error (as determined by this standard) may be contributing to or causing action to be taken to correct an SOL/IROL problem

• To prevent Interconnection frequency excursions of short duration attributed to the ramping of on and off-peak Interchange Transactions

• To support timely transmission congestion relief by requiring corrective load/generation management by the Balancing Authority(ies) within a defined timeframe when participating in transmission loading relief procedures.

• To address the directives of FERC Order 693.

• To ensure that when finalized the standards associated with this project conform to the latest versions of NERC’s Reliability Standards Development Procedure, the Sanction Guidelines of the North American Electric Reliability Corporation, and the ERO Rules of Procedure.

 Additionally, the frequency model used to establish the frequency-based limits will be reviewed to see if additional enhancements are necessary.
