Developers may need to obtain a Site Certification and a Certificate of Public Convenience and Necessity.

Site Certification

Developers seeking to site transmission lines and facilities in Oregon must follow the transmission siting process to obtain a Site Certification from the Oregon Department of Energy (ODE). The siting process is regulated under O.A.R. 345 and O.R.S. 469. The process only applies to siting of high voltage transmission lines of more than 10 miles in length with a capacity of 230kV or more to be constructed in more than one city or county. The process does not apply to siting of facilities within 500 feet of an existing corridor occupied by high voltage transmission lines with a capacity of 230kV or more, or lines of 57kV or more that are rebuilt and upgraded to 230kV along the same right of way. Developers are required to submit an NOI and Site Certificate Application. The review process involves agency consultation, public notice, public hearing, and is subject to approval by ODE. Site Certifications may be subject to challenge by effected parties and judicial review.

The CPCN process is regulated under ORS 758.015 and OAR 860-025-0030. CPCN’s grant authority to the certificate holder to condemn land.
