Wagon Trail Solar Project

​​​​​

The Wagon Trail Solar Project is an approved 500 megawatt (MW) solar photovoltaic (pv) energy generation facility. The facility is approved to be located within an approximately 7,450-acre (11.64 sq. miles) site boundary. Other components include a battery energy storage system (lithium-ion batteries); power collection system; up to two substations; operation and maintenance building; Generator Step Up (GSU) transformer; 0.6 mile overhead 230 kV transmission line; perimeter fencing, access roads and staging areas.

Approved. On September 20, 2024, the Energy facility Siting Council (EFSC or Council) approved the Application for Site Certificate (ASC) for the facility. The ASC, Final Order on ASC, and the site certificate are available in the Timeline below. The certificate holder Wagon Trail Energy Center, LLC, a wholly owned subsidiary of NextEra Energy Resources, LLC, has until September 20, 2027 to comply with applicable preconstruction conditions and begin construction on the facility.

On October 30, 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 in the technology of the approved battery energy storage system (BESS), where a portion of the BESS (up to 15 MWs) would be designed with zinc bromide electrolyte rather than lithium-ion. Zinc-bromide/electrolyte-based BESS technology is fully recyclable within the existing system and does not require heating, ventilation or air conditioning, reducing auxiliary load and operational noise. On November 22, 2024, the Department issued a written determination confirming that, based on review of the “three coulds" under OAR 345-027-0350(4), the changes proposed would not require review through the site certificate amendment process.​
