Facilities

Biglow Canyon Wind Farm is an operational wind energy facility located within a site boundary comprised of approximately 25,000 acres (39 square miles). The facility consists of 217 wind turbines, with a maximum blade tip height of 445 feet, and a peak generating capacity of 450 megawatts (MW).

Operating/Under Review. On December 10, 2025, the Department received the certificate holder's Request for Amendment 4 of the Site Certificate. In the Request, the certificate holder seeks approval to construct a solar photovoltaic power generation facility with up to 125 MW of generating capacity, a battery energy storage systems with up to 500 MW hours of storage capacity, and other related or supporting facilities within a 1,924-acre (3 square-mile) solar micrositing area within the approved site boundary. 

On December 16, 2025, the Department issued a Proposed Order on RFA4. The Proposed Order recommends that EFSC approve RFA4, subject to existing and recommended new and amended conditions. On the same date, the Department issued Public Notice of the Complete RFA4 and Proposed Order on RFA4. The Public Notice included notice of a 45-day comment period ending on January 30, 2026, and a public hearing in Grass Valley, Oregon on January 15, 2026.

All comments received on the Proposed Order can be accessed via the Department's Siting Docket. Additionally, the Department has created a OneDrive Folder for the Amendment Comment Review Process, where participants, including the certificate holder, can upload and download documents for the Comment Review Process or transmit documents via email.

Individuals who commented on the Proposed Order will receive responses from the certificate holder and Department by February 13, 2026. Additional information on how to participate in the Comment Review Process will be provided to those individuals by email.

Sherman County, approximately 4.8 miles northeast of Wasco.
