PSAST Expansion Plan Approved


ColumbiaGrid’s Puget Sound Area Study Team has produced its first 10-year Transmission Expansion Plan for the Puget Sound Area. This plan identifies six transmission projects that, when completed, will provide economical and reliable service to Puget Sound Area load while minimizing the risk of curtailing power transfers between the Northwest and Canada.  For a variety of system conditions, multiple generation and temperature scenarios were studied to evaluate alternative reinforcements and develop the final plan. The plan is available on the CG website at http://www.columbiagrid.org/PSAST-overview.cfm.

"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."
