Participation Overview

ColumbiaGrid’s bylaws identify both the role of members and “qualified non-member participants” in the organization. The members play a significant role in the mission and structure of ColumbiaGrid.  Members and non-member participants, with input from interested persons, develop, draft, and execute functional agreements that define ColumbiaGrid's programs.

There are currently eight members of ColumbiaGrid: Avista Corporation, Bonneville Power Administration, Chelan County PUD, Grant County PUD, Puget Sound Energy, Seattle City Light, Snohomish County PUD, and Tacoma Power. The members elect a board of directors, are responsible for the bylaws, and authorize ColumbiaGrid to enter into Functional Agreements.

Cowlitz PUD, Douglas County PUD and Enbridge participate in ColumbiaGrid in the status of a qualified non-member participant.  These companies have signed onto ColumbiaGrid's Planning and Expansion Functional Agreement (PEFA).

ColumbiaGrid encourages broad participation in its activities. An entity can become involved as a member, participant, interested person, or simply attend ColumbiaGrid’s public meetings as an interested observer.
