McCarthy Completes Tennessee’s Largest Solar Facility

Silicon Ranch

More than 300 people constructed the 53 MWAC solar plant, resulting from a unique public-private partnership

McCarthy Building Companies’ Renewable Energy and Storage group celebrated the completion of construction and commissioning of the 53 megawatt (MWAC) solar facility in Millington, Tennessee, the largest solar farm in the state, at Naval Support Activity (NSA) Mid-South in Millington. The project required more than 300 workers to construct the facility, which has more than 525,000 solar panels, that will provide reliable, resilient power to the NSA Mid-South and Tennessee Valley Authority (TVA) at cost-competitive rates for the next twenty years.

The innovative project is the result of a unique public-private partnership that brought together the City of Millington, the U.S. Navy, Memphis, Light, Gas and Water (MLGW), TVA and Silicon Ranch Corporation with a shared vision to support the local community and the naval base. As part of the unique partnership, Nashville-based Silicon Ranch, the U.S. solar platform for Shell and one of America's largest independent solar power producers, signed a long-term lease with the U.S. Navy for 72 acres of base land and purchased an adjacent 348 acres from the Millington Industrial Development Board (MIDB) for the solar project. McCarthy’s Renewable Energy and Storage Group served as Engineer, Procure, Construct (EPC) contractor for the project.

While the majority of the solar array is located on the adjacent private land, the naval installation received a brand new alternative electrical feed that will increase energy security and resilience at NSA Mid-South. This feature enables the installation's more than 6,500 personnel to focus on their mission at the Navy's Human Resources Center of Excellence. The project also illustrates the value of divesting Navy land that is not crucial to an installation's mission and could be redeveloped through partnerships to benefit the Navy and the surrounding community.  

Underscoring the significance of the landmark project, Tennessee Governor Bill Lee said, "Partnerships fuel innovation, and we are proud of the work by community leaders, the U.S. Navy, and Silicon Ranch to expand solar technology in West Tennessee. We look forward to a continued partnership as we strengthen rural Tennessee, modernize our infrastructure, and prepare for the jobs of the future."

Silicon Ranch Co-Founder and CEO Matt Kisber, who previously served eight (8) years as Tennessee Commissioner of Economic and Community Development, said, "This innovative energy project is the result of a truly collaborative effort, and Silicon Ranch thanks our partners at the U.S. Navy, TVA, MLGW, and the MIDB for making this investment possible. We are especially honored to commission the largest solar facility in our home state of Tennessee and to support the mission of both NSA Mid-South and TVA."

Following the “flip-the-switch” commissioning event, students from the Millington Middle School STEM Robotics team received a special tour of the solar facility.
