ColumbiaGrid is a membership non-profit corporation providing regional grid planning in the Northwest portion of the Western Interconnection that strives for excellence and exists to:

  • improve reliability of the transmission grid via collaborative, cooperative, cost-effective, efficient and insightful long-term regional transmission (‘grid’) expansion planning consistent with planning and reliability standards (i.e. our Core services); and
  • analyze, develop, or facilitate solutions relating to the improved use or expansion of the transmission grid (i.e. our Non-Core services).
  • In carrying out its Mission and Vision, ColumbiaGrid utilizes an integrated single-system view of its Members’ and Qualified Non-Member Parties’ systems and endeavors to provide sustainable benefits for them (which could not be achieved individually or separately), their customers, and the region consistent with the public interest. ColumbiaGrid does not own any distribution, generation, or transmission facilities.

    ColumbiaGrid's planning processes are transparent and open to all interested persons. We value broad participation and interaction with stakeholders, including customers, transmission providers, states, and tribes, and we provide a non-discriminatory forum for interested persons to receive and bring forward pertinent information concerning the regional interconnected transmission system.

    ColumbiaGrid's planning and board meetings are open to parties outside of members and participants, and all notices, agendas, and meeting materials are posted on this website. Under the terms of the bylaws and planning agreements, we notify affected persons of our activities and encourage their participation.

    "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."
