The Boardman to Hemingway Transmission Line is a proposed transmission line – primarily 500-kilovolt – that would extend approximately 300 miles from the proposed Longhorn Substation in Boardman, Oregon to the existing Hemingway Substation in southwestern Idaho.
Proposed. On September 28, 2018, the
Oregon Department of Energy received the complete Application for Site
Certificate (ASC) for the proposed facility. On May 22, 2019 the Department
issued the Draft Proposed Order (DPO), recommending EFSC approval of the
proposed facility (see below). The issuance of the DPO initiates a public
comment period that ends on August 22, 2019 at 5 p.m. (extended by EFSC in response to a public request at the June 26 public hearing in Pendleton). The Department and EFSC held a series of public hearings on the DPO in June 2019. Read transcripts from the hearings in Ontario, Baker City, La Grande, Pendleton and Boardman.
Written comments may
be submitted prior to the close of the public comment period by mail, email,
hand‐delivery or fax to the
hearing officer, in care of:
Senior Siting Analyst

Idaho Power Company (applicant) may request EFSC approval of any combination of route segments for the proposed facility. All route segments must meet all applicable EFSC standards, rules, and ordinances. These route segments may or may not align with the route segments identified in the Record of Decision (ROD) issued by the BLM from the NEPA review. On non-federal land in Oregon, the proposed facility requires EFSC approval. On federal land, the proposed facility requires approval of both the responsible federal agency and EFSC.
