Agua Fria Solar, Storage and Gen-Tie Project

Longroad Energy is developing the proposed Agua Fria Solar, Storage and Gen-Tie Project, which includes an approximately 1.8 mile 500 kV transmission line gen-tie that will connect the Agua Fria Solar and Storage Project to the regional grid at the existing Dugas Substation.

The Project will transmit renewable energy from the proposed Agua Fria Solar and Storage Project to the regional transmission grid. The storage component will also provide ancillary grid services which will support system reliability.

Longroad Energy has initiated the permitting process and hosted in-person and virtual open houses in December 2024 and January 2025 to invite the public to learn and provide input on the Project.

Arizona CEC Gen-Tie Permitting Process

On Thursday, February 6, 2025, the Certificate of Environmental Compatibility (CEC) was filed with the Arizona Corporation Commission (ACC). A link to the CEC application is in the Supplemental Project Materials tab. On Tuesday, March 18, 2025, the Arizona Power Plant and Transmission Line Siting Committee voted unanimously to approve the Certificate of Environmental Compatibility (CEC) for the Agua Fria Gen-Tie Project.

The ACC will hold a public Open Meeting where a written decision on the CEC application is made. The ACC Open Meeting date has not been set. The website will be updated with information on the meeting once a date is set.

Yavapai County Process

The Project will consider public feedback and prepare a full application based on the Solar Ordinance which became effective in December 2024. The Project expects to submit this application in early 2025. The County Board of Supervisors will have final authority to approve the project as a permitted land use. The County permitting process is expected to take 6-9 months.
