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 seven members of ColumbiaGrid: Avista Corporation, Bonneville Power Administration, Chelan County PUD, Grant County PUD, Puget Sound Energy, Seattle City Light, and Tacoma Power. The members elect a board of directors, are responsible for the bylaws, and authorize ColumbiaGrid to enter into Functional Agreements.
Snohomish County PUD has signed both the Planning and Expansion Functional Agreement and the Developmental and Staffing Reliability Functional Agreement as a qualified non-member participant, and Cowlitz County PUD has similarly signed onto the planning agreement in January 2008.
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.
