ColumbiaGrid is not a transmission provider. Eligible Transmission Customers seeking transmission service must continue to access individual Transmission Provider OASIS sites. Avista, BPA, and Puget Sound Energy are Transmission Providers and have their own OASIS sites on WesTTrans which can be accessed through the Select Provider box in the upper left corner of this home page.

BACKGROUND
ColumbiaGrid is a non-profit membership corporation formed to improve the operational efficiency, reliability, and planned expansion of the Northwest transmission grid. As part of our goal to improve efficiency, signatories to the OASIS functional agreement have agreed to establish a presence on OASIS. ColumbiaGrid and its OASIS parties will post relevant information on this home page from time to time. ColumbiaGrid will continue to develop a tool whereby transmission customers can access individual transmission providers through a common portal. This tool is under development. Further information about ColumbiaGrid and its OASIS &Transmission Services program can be found at www.columbiagrid.org.
