The Summit Ridge Wind Farm is an approved wind energy generation facility that would consist of up to 72 wind turbines with a peak generating capacity of 194.4 megawatts, located within a site boundary of approximately 11,000 acres.
Under Review/Approved: The facility has not been built. On January 16, 2019, the Department received a complete Request for Amendment 4 (RFA4) of the Summit Ridge Wind Farm site certificate. RFA4 seeks Council approval to extend the construction commencement and completion deadlines for the facility, as established in the site certificate, by two years. The certificate holder requests that it be allowed until August 19, 2020 to begin construction and until August 19, 2023 to complete construction. The Department re-issued a Draft Proposed Order on Request for Amendment 4 on February 2, 2019 and conducted a public hearing on February 22, 2019 at The Discovery Center in The Dalles, Oregon. On April 2, 2019, the Department issued a Proposed Order on Request for Amendment 4.

On July 3, 2019, the Department issued an amended Proposed Order based on direction from the Energy Facility Siting Council. Issuance of the amended Proposed Order opens an opportunity for those persons who commented on the record of the Draft Proposed Order and the certificate holder to request a contested case proceeding, limited to issues related to the amendment to the Proposed Order. Those persons who are eligible to request a contested case proceeding will receive a separate notice from the Department informing them of this opportunity. The amended Proposed Order is available below.
