WECC develops and implements Regional Reliability Standards and WECC Regional Criteria for the Western Interconnection. Regional Entities are permitted to draft documents that are only applicable to that region using subject-matter-experts acquainted with the physical or operational differences of the local high-voltage grid. WECC also participates in the NERC Reliability Standards Development processes.
NERC Reliability Standards define the reliability requirements for planning and operating the North American Bulk-Electric System (BES) and are developed using a results-based approach that focuses on performance, risk management, and entity capabilities. The Reliability Functional Model defines the functions that need to be performed to ensure the BES operates reliably and is the foundation upon which the Reliability Standards are based.
The Alberta Electric System Operator (AESO) has been leading an initiative to adopt North American Electric Reliability Corporation (NERC) reliability standards as Alberta Reliability Standards. This important work contributes to the reliable operation of the Alberta electric system. The development of a more consistent set of standards is also essential in maintaining and improving the reliability of the North American electric grid.
