The SOTI provides a high-level look at reliability issues across the Western Interconnection over the recent past and near future. WECC examines the conditions on the Colorado River, as record-low water levels have prompted federal action and ominous projections for hydro generation at Glen Canyon and Hoover dams. Learn more in the 2026 Colorado River Hydro Update. WECC has a long history of assuring reliability in the West that began when it was originally formed in 1967 by 40 power systems, then known as the Western Systems Coordinating Council (WSCC). WECC promotes bulk power system reliability and security in the Western Interconnection. WECC is the Regional Entity responsible for compliance monitoring and enforcement and oversees. 9 ISEAS - Interchange Scheduling and Energy Accounting Subcommittee 10:00-11:00 am WSC - WECC Standards Committee 10:00-11:30 am 10 PCS - Protection and Control Subcommittee Protection System and Remedial Action Scheme Misoperation. Automatic Voltage Regulators. The Western Electricity Coordinating Council (WECC) coordinates a number of high voltage power links in western North America. [1][2][3] These links, known as WECC Intertie Paths, are not necessarily single transmission line, rather they are interties between various areas. Regional Entities have the unique ability to draft documents tailored to their region, leveraging subject matter experts who understand the physical and operational nuances of the local high-voltage grid. WECC also actively participates in the NERC Reliability Standards Development processes. The Western Electricity Coordinating Council (WECC) is a non-profit corporation that exists to ensure a reliable Bulk Electric System in the geographic area known as the Western Interconnection. Based on 2023 resource plans, entities in the Western Interconnection plan to build close to 172 GW of resources in the next 10 years. Solar, energy storage, and wind make up more than 85% of these new resources.
