The Sunstone Solar Project (formerly Echo Solar Project) is a proposed 1,200-megawatt solar photovoltaic power generation facility. In addition to the proposed solar photovoltaic arrays, the facility would include:

- Up to 7,200 MW hours of battery storage capacity
- An interconnection substation
- Up to six collector substations
- Up to four operations and maintenance buildings
- Up to 9.5 miles of 230-kilovolt (kV) overhead transmission lines
- Other structures including roads, perimeter fencing and gates.

If approved, the facility would occupy approximately 9,442 acres (14.75 sq. miles) of private land zoned for Exclusive Farm Use within an approximately 10,960-acre (17-sq. mile) site in Morrow County, Oregon.

Proposed. The Department received the preliminary Application for Site Certificate (pASC) on June 30, 2023, and conducted its review of the pASC in coordination with state agencies, and Tribal and local governments. The applicant filed a complete ASC on May 15, 2024. Under OAR 345-015-0190(5), an ASC is complete when the Department finds that an applicant has submitted information adequate for the Council to make findings or impose conditions on all applicable Council standards.

The Department will hold an in-person and remote public information meeting with the applicant to provide information about the proposed facility and the Energy Facility Siting Council (EFSC) siting process; participation details are provided below. The public information meeting is not a public hearing and will not include public testimony or on the record public comments. Opportunity for written or oral testimony will be provided at a later date – during the draft proposed order (DPO) public comment period and public hearing – following issuance of the DPO as described below. This meeting will be recorded and posted on the Department's project webpage after the meeting.
