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.

"In ColumbiaGrid, we now have the ability to resolve the three fundamental transmission questions: What transmission facilities should be built? Who should build them? Who should pay for them? With ColumbiaGrid's independent staff and process to resolve disputes, we can answer these questions effectively and in a timely fashion to facilitate our region's new resource development needs."
~~ Jeff Schlect, Manager, Transmission Services, Avista
