ColumbiaGrid serves as the Northwest Area Coordinator. Sub Area Coordinators submit data to the Area Coordinator. The Area Coordinator then prepares the Northwest powerflow model in accordance with the WECC Data Preparation Manual for inclusion in WECC base cases. Each Northwest Transmission Owner in the NERC registry can select to be a Sub Area Coordinator or have an existing Sub Area Coordinator provide the service. The Sub Area Coordinator list is posted on this page.
To access published WECC base cases, please go to the WECC TSS Base Case page.
