Current Programs

Mission and Vision
ColumbiaGrid’s mission is to improve reliability and efficient use of the transmission grid. We perform transmission planning, and develop and implement solutions related to the operation, use, and expansion of the interconnected Northwest transmission system. In carrying out its mission, ColumbiaGrid endeavors to provide sustainable benefits for its members and the region, and considers environmental concerns, regional interests, and cost-effectiveness.

Planning and Expansion
ColumbiaGrid provides single-utility based transmission planning for the combined network of its participating utilities. The goal of the program is to solve transmission issues regarding what should be built, who should build it, and who should pay for it. The participants in the Planning and Expansion program believe the ColumbiaGrid process provides the planning support and coordination needed to get multi-party transmission projects constructed in the region.
