Seven States Power Corporation, headquartered in Chattanooga, Tenn., announced in September a partnership with MLGW that would deliver a significant infrastructure investment to modernize the electric grid in partnership with Memphis Light, Gas and Water (MLGW) a municipal public utility based in Memphis, TN. Since that time, the project has expanded beyond its original scope.


Originally envisioned as a combined solar-and-storage project, the initiative will now deploy battery storage as a standalone resource designed to support peak demand, improve grid resiliency, and provide MLGW with greater operational flexibility. The project remains backed by Seven States’ award of a landmark $439 million zero-interest loan and grant from the U.S. Department of Agriculture’s Rural Utilities Service (USDA RUS).


The revised approach reflects a strategic decision to prioritize dispatchable energy assets that can respond immediately to system needs. By focusing solely on battery storage, Seven States and MLGW aim to enhance reliability, allowing the utility to better manage demand fluctuations and unexpected outages while maintaining some of the lowest electric rates in the country.


“We are thrilled to build new electric infrastructure to support growing demand and meet the region’s energy needs,” said Betsey Kirk McCall, President and CEO of Seven States Power Corporation. “Battery storage provides a powerful, flexible, and innovative tool that aligns with national priorities around energy dominance, affordability, and reliability.”


Led by Seven States Power Corporation, the project will consist of 100 megawatts of battery storage capacity interconnected with MLGW’s electric distribution system. The batteries will be capable of storing energy from the existing grid and deploying it during periods of peak demand or system stress, helping stabilize the grid while reducing exposure to high-cost power purchases.


“This scalable battery solution allows us to modernize our grid and improve reliability for our customers,” said Doug McGowen, president and CEO of MLGW. “It gives us greater control during peak demand periods to support power supply to our customers across Memphis and Shelby County.”

The battery installations will be constructed at several MLGW substations throughout Memphis and Shelby County. Construction is expected to begin in 2027, with the project targeted for completion by December 2028.


Once operational, the initiative is expected to support the electric needs of approximately 12,000 homes and businesses across Shelby County and create jobs during construction.


Seven States will utilize the award from USDA to build 220MW of battery storage with its electric utility partners in west, middle and east Tennessee. The initiative is among the first of its kind in the Tennessee Valley, demonstrating how federal financing, local ownership, and collaborative partnerships can accelerate deployment of advanced grid technologies. Seven States and MLGW view the project as a model for future battery-focused investments across the Southeast.

Source: Chattanooga Times Free Press | 1 August 2026 | BY DANIEL DASSOW Nearly 20 years ago, the Tennessee Valley Authority and its main customers -- local electric utilities -- formed a new power company with a specific and unprecedented goal. Seven States Power Corp. , a cooperative owned by the region's local utilities, like EPB in Chattanooga , would co-own power plants with TVA. The cooperative would put ownership of power plants in local hands rather than with the U.S. government, which owns TVA and its assets. Seven States would help the federal agency stay below its $30 billion legal debt limit. From 2008 to 2013, Chattanooga-based Seven States owned a 90% stake in TVA's Southaven gas plant in Mississippi. After TVA lowered its debt and bought Seven States out of the plant, the cooperative pivoted to being a development partner for local utilities as they installed solar panels, electric vehicle charging stations and grid-level batteries. Now, Seven States leadership and members say the group is ready to return to its full founding mission of owning a stake in TVA power plants as the federal utility faces many of the same challenges from two decades ago. (READ MORE: Trump budget does not propose privatizing TVA as utility's debt rises) In a video interview, several managers of utilities in the region said Seven States had an opportunity to help TVA stay under its debt limit and meet higher power demand while keeping assets in local hands. "That original intent has never gone away," said Jeff Dykes, CEO of Johnson City-based utility BrightRidge and chair of the Seven States board. "Even though not a lot of action has happened over the years, it's always come back to that hope and desire and intent. We want TVA to be successful at the end of the day. We need TVA to be successful." Seven States is a generation and transmission cooperative , a model in which utilities band together to form a group that can own power plants. While the model is common in other parts of the U.S., TVA's central authority over its seven-state domain is its own model. "TVA is unique in that it owns the generation, it owns the transmission, it's self-regulating and it regulates its own customers," Wes Kelley, CEO at Huntsville Utilities, said in a video interview. "There's nothing else in the country that fits that paradigm." TVA customers have benefited from the model for more than 90 years, Kelley said, though there is room to integrate best practices from other parts of the country. TVA's debt is expected to rise from $23.8 billion at the beginning of 2026 to $27.3 billion by the end of 2027, according to a recent White House budget. The utility has found ways to offload some of the debt, including by entering lease-purchase agreements. The deals allow TVA to receive payment from a third party in exchange for a master lease on a power plant. TVA continues to own the plant while making payments back to the third party, similar to a mortgage. TVA entered a $2 billion lease agreement in May for its Cumberland gas plant in Middle Tennessee, scheduled for completion by the end of the year. The value of the deals is even greater if Seven States is the third party, said Doug McGowen, CEO of Memphis Light, Gas and Water, TVA's largest customer. Because Seven States is owned by the end customers of the product, its interest in maintaining low power costs is the same as residents of the region. "If Seven States was to take ownership of some of the assets through alternative financing, now you have the customers of TVA who are de facto owners of the assets that are generating the electricity that they are ultimately buying," McGowen said. "For us, that means there is a built-in hedge of protection or inherent checks and balances." Seven States is prepared to finance deals on the magnitude of the Cumberland deal, said Betsey Kirk McCall, CEO of the cooperative. The U.S. Department of Agriculture awarded Seven States $439 million in loans and grants last year, which the cooperative is using to build battery systems for its members. The award made Seven States eligible for greater financing, potentially up to the billions of dollars needed to take stake in a major gas plant, McCall said. Funding agencies include the USDA and the U.S. Department of Energy, she said. "None of them have shied away from numbers and volume of plants that we've put in front of the organizations we've been interacting with," McCall said. Seven States is a "force multiplier" for TVA that acts as an extension of its local power customers for the purpose of increasing power supply, McCall said in a later email. She told the TVA board of directors in May that Seven States had completed 222 projects with 80 utilities and received $475 million in state and federal funds since its founding. At its founding in 2007, the cooperative was designed to issue bonds backed by long-term contracts to purchase power. TVA was building gas plants at the time to meet power demand. The TVA board of directors, the members of which are nominated by the president and confirmed by the Senate, approved negotiations with Seven States in 2008. The move was meant to provide stability in ownership if TVA assets were ever sold by the U.S. government.

"(TVA was) up against the same challenges we're up against today," said Edward Kemp, general manager of Starkville Utilities in Mississippi. "At that time, as well as today, all the local power companies really want to be a part of the solution. We want to help. We're not just depending upon TVA to do everything for us." In 2020, TVA granted its local power companies the ability to generate or buy up to 5% of their electricity. Seven States found a niche in helping local utilities develop their own generating sources, work it continues to do. But as TVA's power demand is rising again after a period in the 2010s marked by flat demand growth, Seven States sees a chance to go big again. The cooperative could once again become a major finance partner to TVA, said Chris Jones, president of the Middle Tennessee Electric Membership Corp. The move would only enhance the public power model that's characterized the region since Congress created TVA during the Great Depression. "It can be even better whenever local power companies are given more priority as a practical partner," Jones said. "I think we're seeing that day come, and Seven States is going to be part of it."

Source: Hoodline | 21 July 2026 | By Bob Norris 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.

Jason Reese, General Manager of Shelbyville Power, Water, and Sewer System, leads his LPC with a focus on the evolving technology that strengthens reliability, improves efficiency, and enhances service for his customers. He took a moment to highlight some of the innovation that is truly making a difference across his community. AMI technology has had the greatest impact on Shelbyville Power, Water, and Sewer Systems and our community. Our system converted to AMI meters nearly 14 years ago, and this technology has enabled us to streamline many manual utility processes and improve operational efficiency in our electric and water systems. AMI electric meters with remote disconnect capabilities have enabled us to remotely disconnect and reconnect customers on the collections list, reducing truck rolls, improving operational efficiency, and enhancing employee safety. AMI water meters allow us to identify water leaks much sooner than was previously possible, benefiting both our customers and our efforts to reduce water loss. Our team is also very proud of our recent pilot distribution automation project installed on three circuits, each served by a different substation, which provide power to Shelbyville's two main corridors. Implementing distribution automation on these circuits helps minimize the number of customers affected during outages or the loss of a power source, improving service reliability for the community. Building on its success, our long-term goal is to expand distribution automation across all eighteen circuits and all three substations to further enhance system reliability, resiliency, and service to our customers. As the Valley continues to evolve and change, Jason knows firsthand that Seven States is a trusted industry resource and a valuable partner in helping LPCs navigate the process of implementing new technology projects. In June 2026, we completed our first EV charger project as part of the TN Fast Charge Network, and I cannot say enough good things about how Seven States and Joe Knox helped guide us through that process. These chargers have already been a hit with our community and have also brought in travelers from out of town to our downtown square. Everything from start to finish went as smoothly as it possibly could, and that is due to Seven States.  While technology continues to transform the utility industry every day, Jason believes some aspects of the system will always depend on the knowledgeable workers who keep everything running behind the scenes. Hands-on infrastructure maintenance is one traditional utility practice that I believe will never completely disappear, regardless of how much technology advances. No matter how sophisticated our systems become, maintaining physical infrastructure will always require skilled workers to perform inspections, repairs, and upgrades in the field. Just as the utility industry is built on connections that span across communities, music has a way of bringing people together, even across generations. When asked which celebrity he would most like to meet for dinner, his choice was a musician who has stood the test of time. It would have to be Elvis Presley. As someone who has a love for all genres of music, to be able to sit down and talk with him about his career and experiences from gospel to rock-n-roll would be an absolute thrill!
