About Membership

The rights and obligations of the ColumbiaGrid members are defined in the bylaws of the corporation.  New members can be added via an amendment to the bylaws, and the existing members must consider adding new members at least yearly.  Interested entities are encouraged to apply, although it is not necessary to become a member to participate in the programs operated by ColumbiaGrid.

All of the current members of ColumbiaGrid operate control areas and act as balancing authorities, and they actively participate in regional forums concerning power planning and operations.  A list and brief description of current members can be found under ColumbiaGrid Members.

ColumbiaGrid’s members funded the 2006 start-up of the organization under The Second Funding Agreement . Funding is allocated among the members through a three-part formula. One part of the formula provides for an equal sharing of 30 percent of the total funding; a second part consists of sharing 40 percent of costs pro-rata to current transmission investment; and the third part is a sharing of 30 percent of costs pro-rata to load service. There is an adjustment made to ensure that no one member has an overall allocated share above 49.90 percent since voting rights are based upon share percentages.  Current share percentages can be downloaded here.

The members have also agreed in principle to continue to fund corporate expenses separately through a new Third Funding Agreement.  This agreement is expected extend into the latter part of 2010, provide a level of funding similar to the Second Funding Agreement, and additionally establish a permanent working capital account of $1 million.

For further information about membership, contact Patrick Damiano, ColumbiaGrid's CEO.

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."
