Western Electricity Coordinating Council (WECC)

The Western Electricity Coordinating Council (WECC) is the Regional Entity for the Western Interconnection. As the Regional Entity, WECC is charged with coordinating and promoting Bulk Electric System reliability. Additionally, WECC coordinates the operating and planning activities of its Western Interconnection members.

The Western Interconnection is uniquely structured in that it does not have organized markets (outside of the California ISO), but rather, is organized into 38 separate balancing authorities (BAs).


Each BA is responsible for balancing loads and resources within their respective boundaries. Such an organizational structure often presents challenges to reliability, particularly when integrating large amounts of variable generation.
