Current Programs

Multi-System Open Season Scoping Process
ColumbiaGrid is facilitating an Open Season Scoping Process through which regional transmission providers, transmission customers and interested persons are examining alternative transmission service business practices. One goal of this effort is to address a service request that might span more than one transmission owner’s system and to deal with that request in a comprehensive manner. Other goals are to investigate cost allocation issues and to encourage the construction of needed new transmission across multiple systems.

Joint Initiative with NTTG & WestConnect
ColumbiaGrid has joined with NTTG and WestConnect to pursue several projects of mutual interest. ColumbiaGrid has offered the use of this website for posting activities of the Joint Initiative.

Planning and Expansion
ColumbiaGrid is an independent entity, and its transmission planning process and involvement in other planning activities in the region assures projects will be thoroughly studied and alternatives considered. ColumbiaGrid also provides mechanisms to address cost allocation issues and get needed projects built.

OASIS & Trans. Svcs.
ColumbiaGrid’s long-term OASIS and Transmission Services Program includes establishing and administering a common OASIS portal, determining methodologies for a common ATC, and working toward common queue methods for both transmission service and interconnection requests.

Reliability Services (under development)
The long-term Reliability Services Program will be an outgrowth of analyses performed under DSRFA. It will provide participants with services designed to improve operations of the transmission grid. The technical development work group in this area is known as the Reliability Small Group.

Corporate Development
This program includes activities focused on ColumbiaGrid as a corporation.
