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.

Douglas County PUD participates in ColumbiaGrid in the status of a qualified non-member participant.  Douglas has 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.

Chelan County PUD

"Chelan PUD is a strong supporter of ColumbiaGrid and the work that’s accomplished through the transmission Planning and Expansion Functional Agreement (PEFA). As a result of that process, the mid-C utilities (Chelan, Grant and Douglas PUDs) and Bonneville Power Administration were able to reach an agreement that defined the need for a new transmission line, as well as determine who will construct, own and pay for the facility. Those difficult decisions were made successful through the expert and independent expertise of the ColumbiaGrid staff."
