Bulk Electric System Definition Initiative
March 2014
 
At a Glance
·         The revised Bulk Electric System definition becomes effective July 1, 2014.
·         The ERO developed enterprise-wide processes to provide a uniform, clear way of determining assets contained within the bulk electric system.
·         An ERO enterprise software tool was developed to provide single method for the ERO, Regions and registered entities to manage submittals of inclusions, exclusions and self-determinations.
·         Documents and training continue to be finalized and deployed to assist industry with the transition and can be found on the BES web page, including the BES notification review guidelines and the BES exception request evaluation guidelines. A BES definition reference document is being developed and will be posted upon completion.
·         The new BES definition, processes, and tools provide a consistent way to identify assets and manage workflow, which will ultimately provide clarity and certainty of the BES elements and enhance the reliability of the bulk electric system.
 
Background
In November 2010, the Federal Energy Regulatory Commission issued Order 773 directing NERC to revise the Bulk Electric System definition to encompass all elements and facilities necessary to the reliable operation and planning of the bulk electric system. To that end, the Electric Reliability Organization Enterprise (NERC and the Regions) developed corresponding processes to determine inclusion and exclusions to the definition, and an enterprise-wide application to support that process, called the BES Notifications and Exceptions tool (BESnet).
 
Benefit
The ERO developed processes and tool to provide a uniform, clear way of determining asset inclusions, exclusions and self-determinations under the revised BES definition, which becomes effective July 1, 2014. The ERO process and tool provide a consistent way to identify assets, manage workflow, which will ultimately enhance the reliability of the bulk power system.
 
More Information
Reference documents and training continue to be developed and updated to assist industry with the transition. These materials and schedules for training/webinars can be found on the BES web page. NERC and the Regions strongly encourage registered entities to use these resources and the training opportunities, as well as contact their respective Regional or NERC staff for further information.
