ColumbiaGrid has completed the 2020 System Assessment

Dear Planning Participants and Interested Persons;

ColumbiaGrid's final 2020 System Assessment report has been posted on ColumbiaGrid's website. This report analyzes the reliability of the transmission system over the next ten years as well as identifies potential areas where additional system reinforcements may be needed. In addition, the contents in this report, along with the 2019 System Assessment Report, will be used as a basis for the development of ColumbiaGrid's 2020 Biennial Transmission Expansion Plan (BTEP) that will be issued in October 2020.

An electronic copy of the 2020 System Assessment report is available below. Hard copies are available upon request.

"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."
