Montague Wind Power Facility

The Montague Wind Power Facility is a 201 MW wind facility consisting of 56 wind turbines within an approximately 29,607 acre site boundary.

Operating: Commercial operation of the facility commenced in October 2019. On December 9, 2024, the certificate holder submitted an Amendment Determination Request (ADR) pursuant to OAR 345-027-0357 requesting a written determination from the Oregon Department of Energy on whether a proposed change necessitates review through the site certificate amendment process. The ADR evaluates a proposed change to install a concrete pad and 18 x 36 foot shed, adjacent to a shared Operations and Maintenance Building within the Leaning Juniper IIB site boundary. Following review of the ADR, the Department will issue a written determination, to be provided on the project webpage below, and announced at a subsequent Council meeting.
