Pegasus Project 500 kV Transmission Line in Arizona, U.S. Enters Permitting Hearing

en.Wedoany.com Reported - On November 9, the environmental compatibility permitting hearing for the 500 kV transmission line of the Pegasus Interconnection Project in Arizona, U.S., commenced in Show Low, Navajo County. The project, applied for construction by Pegasus Generation LLC, proposes to build approximately 4.1 miles of new overhead transmission line to connect the Pegasus Energy Project with the regional 500 kV transmission network. The Arizona Power Plant and Transmission Line Siting Committee plans to review the permit application from November 9 to 12 and to hear public comments both in person and remotely, marking the project's entry into the formal permitting hearing stage.

The line is a generation interconnection facility for the Pegasus Energy Project and is proposed to connect to Salt River Project (SRP)'s existing Coronado–Silver King 500 kV transmission line via the planned Cygnus Substation. The project is located in an unincorporated area of Navajo County, with the route planned to cross private land and state trust land administered by the Arizona State Land Department, and will be built as an overhead line.

Pegasus Generation LLC submitted an application for an environmental compatibility certificate to Arizona regulators on September 28. The hearing addresses line siting, environmental compatibility, and construction permitting, under regulatory case number L-21422A-26-0416-00270. The Siting Committee is responsible for reviewing the application materials and related evidence and for handling project construction permitting matters in accordance with state regulatory procedures.

The hearing was held at 11 a.m. on November 9 in Show Low, with subsequent sessions scheduled to continue at 9 a.m. daily from November 10 to 12. A dedicated public comment session was also scheduled for 5:30 p.m. on November 9, allowing residents and stakeholders to participate in person, by phone, or via video conference. The project developer previously held a public open house on August 11 to introduce the proposed line and planning scheme to local residents.

The Pegasus Energy Project plans to build 330 MW of photovoltaic generation facilities approximately 15 miles northwest of Snowflake in Navajo County, covering about 2,645 acres. The developer plans to connect the power to the regional transmission network through new step-up and interconnection facilities, with the energy project expected to begin operations in 2028. This 500 kV line permit application is a separate regulatory proceeding for its supporting grid interconnection works.
