Mission and Vision
ColumbiaGrid’s mission is to improve the reliability and efficient use of the Northwest’s transmission grid. ColumbiaGrid performs grid expansion planning, and develops and implements solutions related to the expansion, operation, reliability, and use of the interconnected Northwest transmission system. In carrying out its mission, ColumbiaGrid endeavors to provide sustainable benefits for its members and the region, while considering environmental concerns, regional interests, and cost-effectiveness. ColumbiaGrid Work Plan

Planning and Expansion
ColumbiaGrid provides grid expansion planning based on a single-utility concept for the combined transmission grids of its planning parties. The goal of grid expansion planning is to determine reasonable solutions, or mitigations, of transmission grid issues pertaining to serving load and complying with reliability standards. In doing so, ColumbiaGrid helps to determine what should be built, where it should be built, and when it should be built. The participants in the Planning and Expansion program look to ColumbiaGrid’s grid expansion planning to coordinate and support committing multi-party transmission projects in the ColumbiaGrid region.

Other Services

Often, these grid services are implemented via separate functional agreements.
