Maps of the Western Interconnection

WECC has four maps available:

  • The WECC Planned Facilities Map illustrates future projects through the defined period. This map represents the kV, ownership, approximate location, and expected in-service date of tentative and committed projects through the defined period.
  • The WECC Map of Principal Transmission Lines denotes existing transmission lines and other electrical devices through the defined period. This map represents the kV, ownership, and approximate location of existing projects and projects to be in-service through the defined period.
  • The WECC Map of Balancing Authorities (BA) represents the locations of the BAs in the Western Interconnection. Two versions are provided:
    • The full detail WECC BA map
    • The general WECC BA map is the same as the full detail map but it omits the table of full labels for each BA
