Memphis Utility Proposes Massive Battery Storage Across Shelby County

Memphis Light, Gas & Water is gearing up for a massive battery play that could reshape how Shelby County keeps the lights on and the bills in check. Utility leaders say a new countywide battery storage network could cut pricey wholesale power purchases and help keep electric rates steady well into the next decade.


The idea is simple enough, even if the hardware is anything but. MLGW wants large-scale batteries stationed at key substations around the county, ready to kick in when demand spikes and wholesale prices jump.


What’s Being Proposed


MLGW outlined a plan to install 125 megawatts of battery storage spread across nine substations in Shelby County. The systems would quietly charge up overnight when power is cheaper, then discharge during peak hours to reduce what the utility has to buy from the Tennessee Valley Authority at premium prices.


Locations floated by officials include Cordova, Collierville, Whitehaven and North Memphis, according to Action News 5. It is a far cry from a backup battery in your hallway closet.


Project Partners And Funding


Regional developer Seven States Power, which is leading the broader Energy Express initiative, is lining up the pieces behind the scenes. The MLGW portion is expected to account for roughly 100 megawatts of a 220-megawatt rollout across Tennessee, supported by about $439 million in zero-interest loans and grants from USDA’s Rural Utilities Service.


Seven States Power says construction is scheduled to start in 2027, with a goal of having the full system up and running by December 2028.


What City Leaders Were Told


Speaking to the Memphis City Council, MLGW President Doug McGowen framed the storage push as a direct play to keep customer bills from climbing.


He said the strategy is “designed to push rates downward, down, not up,” and MLGW told council members it does not expect an electric rate increase until after 2030, according to Action News 5.


How This Fits With MLGW’s Earlier Plans


This battery push did not come out of nowhere. In March 2025, MLGW issued a request for proposals seeking roughly 100 megawatts of solar generation paired with about 80 megawatts of utility-scale battery storage, along with smaller distribution-level projects.


According to MLGW, that RFP let vendors pitch either utility-owned projects or third-party power purchase deals as the utility began testing the waters on local generation and storage.


Benefits And Outstanding Questions


Seven States estimates the combined battery installations would support power needs for roughly 12,000 homes and create construction jobs along the way. The setup is also expected to limit MLGW’s exposure to the most expensive peak market purchases.


But some big pieces still have to fall into place. Siting, permitting and contract details have not been finalized, and the partners say they plan public outreach and technical reviews before any shovels hit the ground, as outlined by Seven States Power.


Next steps include more detailed technical studies, regulatory sign-offs, and public briefings before contracts are locked in and crews mobilize in 2027. If the schedule holds, the batteries would be online by December 2028, giving MLGW a new tool to shave peak costs and put continued downward pressure on rates across Shelby County.

GUNTERSVILLE, AL — October 2, 2026 — Electric Board of Guntersville and the City of Guntersville, in partnership with Seven States Power Corporation, today celebrated the ribbon cutting and official unveiling of a new battery energy storage system (BESS) and two electric vehicle (EV) charging ports at the Guntersville Senior Center. The project represents an investment in reliability, emergency preparedness and modern energy infrastructure for the Guntersville community. The battery system is designed to provide backup power to the Senior Center during outages, helping the facility continue serving residents when reliable electricity is needed most. The addition of battery storage will also enable the Senior Center to meet critical emergency preparedness requirements for designation as a FEMA shelter, strengthening its ability to serve residents during severe weather and other emergency events. “This project is about putting innovative technology to work in a way that directly benefits the people we serve,” said Jason Kirkland, General Manager of Electric Board of Guntersville. “By adding battery storage and EV charging at the Senior Center, we are investing in infrastructure that supports reliability today while preparing our community for the needs of tomorrow.” The City of Guntersville partnered with Electric Board of Guntersville and Seven States to bring a 261kWh battery energy storage system (BESS) to the Senior Center, supporting an investment that strengthens the facility’s role as a vital community resource and enhances its ability to serve residents during emergencies. The battery unit will store energy during off-peak hours and be used as necessary to supply power to the facility during an outage or to deploy power for up to 2 hours back onto the Guntersville electric grid. The two new EV charging ports complement the battery installation by expanding access to charging infrastructure for residents and visitors. Together, the technologies demonstrate how community-scale energy projects can provide practical benefits while helping local power companies modernize infrastructure. “What makes this project special is its purpose. This battery is more than a piece of energy infrastructure, it provides another tool to help Guntersville care for its residents and keep an important community facility powered when it matters most,” said Guntersville Mayor Leigh Dollar. “Seven States was created to help local power companies turn opportunities like this into projects that deliver meaningful benefits in their communities,” said Betsey Kirk McCall, President & CEO of Seven States Power Corporation. The Guntersville project is part of Seven States’ broader work with local power companies across the Tennessee Valley to develop and finance energy infrastructure tailored to local needs.

CHATTANOOGA, Tenn. — September 02, 2026 — Seven States Power Corporation has issued a Request for Proposals (RFP) seeking a qualified provider to supply battery energy storage systems and a 20-year long-term service agreement for the Energy Express Project, a 220-megawatt battery storage initiative being developed in partnership with Memphis Light, Gas and Water (MLGW), Nashville Electric Service (NES), and BrightRidge. The competitive procurement represents another major milestone as Seven States advances one of the Tennessee Valley’s most significant investments in distribution-connected battery storage. The Energy Express Project will deploy battery energy storage across multiple locations in west, middle, and east Tennessee, including 100MW in partnership with MLGW, 100MW with NES, and 20MW with BrightRidge. Seven States will own and operate the assets, which will be interconnected with the local utilities’ distribution systems and designed to charge during lower-demand periods and discharge when demand is highest. The systems will provide the utility partners with greater operational flexibility while helping manage peak demand, strengthen reliability, and make more efficient use of existing grid infrastructure. “Moving into procurement marks an important step toward delivering these assets for our local power company partners and the communities they serve,” said Betsey Kirk McCall, President and CEO of Seven States Power Corporation. “Through Energy Express, we are combining federal financing, local partnerships and innovative energy technology to make a long-term investment in the Tennessee Valley’s electric infrastructure. This RFP will help us identify a partner capable not only of delivering the technology, but of supporting its performance and reliability throughout the life of the project.” The Energy Express Project is backed by Seven States’ $439 million award through the U.S. Department of Agriculture’s Rural Utilities Service New Empowering Rural America (New ERA) program. Construction is expected to begin in 2027, with the battery assets targeted for commissioning in late 2028.
