WECC's online tools have been carefully designed to be efficient and easy to use. Participate in our activities or find and gather necessary information from our databases.
The BESnet application is the official means of notifications to Regional Entities of newly identified inclusions and exclusions as a result of application of the Bulk Electric System definition.
The EFT Server is a file upload tool for audits, spot checks and ad hoc requests. The main function is to exchange files between WECC and Registered Entities in conjunction with webCDMS.
Secure Workspace User Guide
WECC Registration identifies and registers bulk power system users, owners and operators who are responsible for performing specified reliability functions to which requirements of mandatory NERC Reliability Standards are applicable.
These web mapping applications provide the ability to view and access the environmental/cultural risk classification Data Layers developed by WECC stakeholders as part of the Regional Transmission Expansion Planning project funded through a grant from the US Department of Energy. The Data Layers available through this application are intended for use in regional transmission expansion planning; siting level analyses for specific transmission projects, while they may employ some of the same data sets used here, will require other, project level data sets and consideration.
Note: These tools require Chrome or Firefox web browsers
Information is presented that contains active entities and the functions for which they are currently registered. This data is refreshed on a monthly basis.
WECC Provides a number of maps to assist in visualizing interconnection paths and other data. You can find these maps here.
The ERO Enterprise Program Alignment Process is intended to enhance efforts to identify, prioritize, and resolve alignment issues across the ERO Enterprise. This is a repeatable, transparent process that registered entities (or other relevant industry stakeholders) may use to report any perceived inconsistency in the approach, methods, or practices implemented and executed by the Regional Entities.
The Standards Index is a filterable database inclusive of all NERC Standards, both current and retired.
Western Renewable Energy Generation Information System (WREGIS) account holders can login to the tracking system to manage their individual renewable energy certificate (REC) portfolios.
Many of our work products are developed in coordination with external subject matter experts and other interested parties. These stakeholders participate in our processes through committees focused on topics that impact reliability in the Western Interconnection. Many of these committees report to our Board of Directors.

Through our various reliability-related activities, we provide critical support to entities throughout the Western Interconnection in carrying out their reliability missions. Our strength and value lie in our ability to consistently leverage the Interconnection-wide perspective in our day-to-day activities, as well as our forward-thinking products and services.
