2010 System Assessment Published

The final ColumbiaGrid 2010 System Assessment report has been posted.  The report analyzes the reliability of the transmission system over the next ten years and identifies areas where there may be reliability issues. Study Teams are formed to address reliability issues when they affect more than one ColumbiaGrid planning participant. As a result of this year's assessment, ColumbiaGrid is proposing three new areas of study; Olympic Peninsula, Eastern Washington/Northern Idaho and Okanogan. Other study needs could be incorporated in existing Puget Sound area West of Cascades and Northern Mid-C Study Teams.

"Chelan PUD is a strong supporter of ColumbiaGrid and the work that’s accomplished through the transmission Planning and Expansion Functional Agreement (PEFA). As a result of that process, the mid-C utilities (Chelan, Grant and Douglas PUDs) and Bonneville Power Administration were able to reach an agreement that defined the need for a new transmission line, as well as determine who will construct, own and pay for the facility. Those difficult decisions were made successful through the expert and independent expertise of the ColumbiaGrid staff."
