Line voltage: 235 kV
Distance: Approx. 0.25 mile
Owner & Developer:
Ørsted Onshore 
Operations: Estimated 2024

About the project

Located in Pinal County, Arizona, a 0.25 mile transmission line will connect the Eleven Mile Solar Center to the Pinal Central Substation. Through this 235 kV electrical line, electricity generated by solar energy will be transmitted onto the Arizona grid. An estimated 900,000 MWh of energy will be generated annually, or enough to power 63,800 Arizona homes each year. The Eleven Mile Solar Center will help meet the energy needs of the state by providing clean, flexible, solar-powered electricity

Eleven Mile Solar Center LLC received a Certificate of Environmental Compatibility (CEC) from the Arizona Corporation Commission (ACC) for the proposed transmission line (also referred to as a gen-tie line), which will be constructed within a new dedicated utility ROW. The project area is currently heavily developed with transmission lines, and portions of the 0.25-mile-long gen-tie line may consist of both underground and above ground segments.

We want to hear from you

Community feedback is important during design and development. We want to discuss the project with you. 

Project planning

In 2020, Eleven Mile Solar Center LLC, engaged AECOM Technical Services, Inc. (AECOM), an environmental consulting firm, to provide background environmental studies for the Eleven Mile Solar Center. In 2022, AECOM was also retained to prepare the CEC application for the gen-tie line, which includes baseline information on land use and visual, biological, cultural, and recreational resources in the area surrounding the CEC study area. Eleven Mile Solar Center LLC has been actively communicating with the public and agencies about the associated solar project for several years, and has secured the necessary zoning to construct and operate the facility.
