ColumbiaGrid is a non-profit membership corporation formed in 2006 to improve the operational efficiency, reliability, and planned expansion of the Pacific Northwest transmission grid. The corporation itself does not own transmission, but its members and the parties to its agreements own and operate an extensive network of transmission facilities.
ColumbiaGrid has substantive responsibilities for transmission planning, reliability, Open-Access Same-Time Information System (OASIS), and other development services. These tasks are defined and funded through a series of “Functional Agreements” with members and other participants. Development of these agreements is carried out in a public process with broad participation.
Materials related to all aspects of development and corporate business are posted on this website. This includes a link near the end of the Documents section to activities early in ColumbiaGrid's history. To view our Annual Report, that is published every January, click here.
