Facilities

​​​​​​​​​​​​​​​​

The Oregon Trail Solar Facility is an approved energy generation facility to include any combination of wind and solar facility components not to exceed 41 MW, including up to 16 wind turbines or up to 1,228 acres of solar photovoltaic energy generation equipment. Facility components would be located within an approved 13,866 acre site boundary.

Approved: Construction of the facility must commence on or before August 30, 2022. 

On August 19, 2022, the Department received preliminary Request for Amendment 1 for the Oregon Trail Solar Facility. pRFA1 seeking Council approval for a three year extension to the construction commencement deadline (identified in Condition 24), and a revision to condition 50(b) related to cultural resource monitoring. The construction commencement deadline extension would make the new deadline August 30, 2025.

Preliminary Request for Amendment 1 includes a Type B Review Amendment Determination Request (Type B Review ADR) seeking concurrence that the amendment request be processed under Type B review, which was evaluated by the Department.

The Department issued its Type B Review ADR determination to the certificate holder on November 10, 2022, disagreeing with the certificate holder's analysis and confirming that Type A review be maintained for the amendment request. 

Following review and completeness determination of pRFA1, the Department will issue a Draft Proposed Order and Notice of Draft Proposed Order, initiating a public comment period on both the amendment request and Draft Proposed Order. These materials will be posted to the project webpage below upon issuance.​
