Current Programs

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.

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.

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.

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.

Energy Imbalance Market (EIM)
ColumbiaGrid is facilitating a collaborative effort among its Members and other willing regional parties to analyze and understand the benefits and costs analyses, performed through WECC, for a proposed voluntary energy imbalance market (EIM) being discussed in the Western Interconnection. Future efforts may be expanded, based on the interests of ColumbiaGrid’s Members, to further explore energy imbalance and capacity markets.

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