Yellow Rosebush Energy Center

Facilities

Yellow Rosebush Energy Center is a proposed 800 megawatt (MW) solar photovoltaic power generation facility with related or supporting facilities including battery storage system, transmission line (two alternatives) substation, O&M building, and new and improved roads.

If approved, the facility would be located within a site boundary of approximately 8,075 acres (12.6 sq. miles) of private land zoned for Exclusive Farm Use (EFU) in Wasco and Sherman counties (the transmission line alternative is the only facility component located in Sherman County).

Proposed/Under Review. The applicant filed a complete ASC on September 5, 2025. A copy of the complete ASC is available in the Project Timeline below.

On December 5, 2025, the Department issued its Proposed Order on the ASC. On the same date, the Department issued a Public Notice of the Proposed Order and Opportunity to Request to Participate in the Contested Case. In response to this Notice, two petitions for contested case were received. On February 9, 2026, Office of Administrative Hearing’s Administrative Law Judge (ALJ) Kate Triana issued an Order on Party Status and Issues, granting 1 petitioner party status on 1 issue.

ALJ Triana presided over the contested case proceeding and provided status updates to Council. ALJ Triana issued a Consolidated Ruling on June 12, 2026. A copy of that ruling is posted in the timeline below. The appeals deadline is July 10, 2026.

Council will have the opportunity to review the PCCO and Department's Proposed Order and will make a decision to approve, modify, or reject the PCCO and Proposed Order in a Final Order on the ASC at a future Council meeting.

The Department has developed and made publicly available the Administrative and Decision Record for the ASC, where the public and parties to the contested case, including the certificate holder, can access record documents associated with the project to date. The Administrative and Decision Record is also available in the Timeline below.
