Longroad Energy is developing the proposed Sun Streams Expansion Gen-Tie Project (Project) which includes a new substation and an approximately 5-mile gen-tie that will connect the Sun Streams Expansion Solar and Storage Project to the regional grid at the existing Chukar Substation. The Project will transmit renewable energy from the proposed Sun Streams Expansion Solar and Storage Project to the regional transmission grid. The storage component will also provide ancillary grid services which will support system reliability.

Longroad is also preparing an application seeking a Certificate of Environmental Compatibility (CEC) to be filed with the Arizona Corporation Commission (ACC) in August 2022. The CEC process includes public hearings with the Arizona Power Plant and Transmission Line Siting Committee before seeking final approval from the ACC. Hearings before the Line Siting Committee will occur in September 2022. Information about the project, the CEC filing, and the hearings will be posted to the website as information becomes available.
