Flexibility: Better Together
July 17, 2020

More than two years ago, the Seven States Power board of directors charted a new course, one where our energy services company would help members meet demand for renewable solutions. Now, as local power companies usher in a new era of distribution-level power supply flexibility through TVA’s Long-Term Partnership Agreement, we are uniquely positioned to help them achieve their goals.

“Time and again, the old adage that “when we work together everyone achieves more,” has proven true for the 154 local power companies in the Valley. said Seven States Power EVP Betsey Kirk McCall. “At Seven States Power we are leveraging the combined experiences and best practices of our member-owners and pulling from a deep well of technical knowledge and economies of scale to help them build for their future. Best of all, our efficient, creative and cost-effective services are keeping the resources, investment and expertise within the Valley.”  Structured as a generation & transmission cooperative, Seven States is member-owned by the local power companies (LPCs) in the Valley, so the experience and revenue gained from each project extends to the benefit of the members.

When TVA distributed a revised Power Supply Flexibility Agreement in late June, our staff had already begun working with members to install renewable technologies. While some LPCs are just beginning to explore carbon-free or carbon-neutral technologies, others have been working with us for months in preparation for a summer project launch.

Several of our members are planning installation or expansion of solar coupled with large scale battery storage to maximize the operation and value of the solar array. Combined heat and power projects are in the early stages of development in Tennessee and Mississippi, one for an industrial customer and the other for a wastewater treatment facility.

“We are excited to see Seven States growing because we can complement each other as we get things going,” said Doug Perry, TVA’s senior vice president of commercial energy solutions. “We need to see more distribution-scale solar, and the Seven States team has the ability to work with LPCs to bring information, lessons learned, and support that will help them make the best decisions for the customers of the Valley.”

Perry noted that Seven State Power’s expertise in disciplines like commercial engineering, grid connection, contracts, project management and maximizing economies of scale can help LPCs that partner with the energy service company. He lauded the formation of Seven States Energy, LLC, to leverage tax incentives, own assets, and to complete member projects effectively and efficiently. According to Perry, about a dozen LPCs throughout the Valley have distribution-scale generation projects underway.

When recently asked about Seven States Power’s role as a vehicle for LPCs pursuing distribution-level flexibility projects, Appalachian Electric Cooperative General Manager Greg Williams said, “When I think of the words innovative technology and flexibility, Seven States comes to mind because those two things come together in the new world we live in. A few weeks ago, we didn’t have this capability or the opportunity to go out and generate our own electricity. We do today, and what better vehicle to do that than through turnkey projects with our own company, Seven States? It’s a better solution for the Valley.”

Energy Express: Advancing Tennessee's Electric Future

By Jessica Bradshaw • July 1, 2026
The second quarter of 2026 has been a productive period for the Seven States team, with much of the spring and early summer dedicated to engaging utility leaders, elected officials, community stakeholders, and the public to share the vision, progress, and benefits of the Energy Express Project. Members of the Seven States team had the privilege of speaking with leaders from BrightRidge, Memphis Light, Gas and Water (MLGW), and the Nashville Electric Service (NES). These publicly held meetings served as important forums to answer questions, share project milestones, and demonstrate how the Energy Express Project will modernize and strengthen the Valley’s electric infrastructure for decades to come. Led by Seven States, the project will deliver 220MW of battery storage capacity across multiple site locations in partnership with BrightRidge (20MW), MLGW (100MW), and NES (100MW). The project is 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). A primary objective of the project will be creating a stronger, more flexible electric grid capable of meeting increasing energy demands related to the state's industrial, commercial, and residential sectors. The battery assets will charge during off peak hours and discharge during peak hours to help peak shave, reducing costs and grid strain while providing utilities with greater operational flexibility. Originally envisioned as a utility scale solar project, the initiative will now deploy battery storage as a standalone resource on the distribution system and the assets will be owned and operated by Seven States. The project's outreach efforts have been featured by local media outlets (highlighted below), and a dedicated website has been launched to provide project updates while offering the public an opportunity to submit comments and questions. As we continue advancing the project, we remain grateful for the opportunity to engage with partners across Tennessee and share our progress with the Seven States audience. We look forward to continuing these conversations with utilities, local governments, community organizations, and rate payers as the Energy Express Project moves forward. Together, we are building and energizing the grid of the future. POWERING UP: Chattanooga-based Seven States to build grid batteries with $439M in federal funds BrightRidge, Seven State Power Corporation partnership to bring battery storage to the Tennessee Valley MLGW and Seven States Power form partnership for battery storage MLGW, Seven States make deal to deploy battery storage Energy Express Project to Bring Battery Storage to Greater Nashville Nashville's power grid is about to get a boost. Here's how.

Seven States Power Corporation Announces Large-Scale Battery Storage in Partnership with NES

By Jessica Bradshaw • June 25, 2026
June 25, 2026 Seven States Power Corporation, headquartered in Chattanooga, Tenn., is pleased to announce that it will deliver a significant infrastructure investment to modernize the electric grid in partnership with Nashville Electric Service (NES), a municipal public utility based in Nashville, TN. The initiative, named the Energy Express Project, will deploy battery storage as a standalone resource designed to support peak demand, improve grid resiliency, and provide NES with greater operational flexibility. The project is 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). This announcement follows similar recent announcements related to additional project locations across the state in partnership with Memphis Light, Gas and Water in Memphis, TN and BrightRidge in Johnson City, TN. The 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 its partners aim to enhance reliability, allowing the utilities to better manage demand fluctuations and unexpected outages while maintaining some of the lowest electric rates in the country. “The Energy Express Project demonstrates how federal financing, local ownership, and collaborative partnerships can accelerate deployment of advanced grid technologies to help manage growing demand to meet the region’s energy needs,” said Betsey Kirk McCall, President and CEO of Seven States Power Corporation. “Battery storage provides an innovative tool that aligns with national priorities around energy dominance, affordability, and reliability.” Led by Seven States, the project will consist of 100 megawatts of battery storage capacity interconnected with NES’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. “Our partnership with the team of experts at Seven States will allow us to deliver a battery solution that will modernize our grid, improve operations, and provide reliability for our customers,” said Teresa Broyles-Aplin, president and CEO of NES. “It gives us greater control during peak demand periods and supports our ongoing effort toward reliable energy distribution.” The battery installations will be constructed at several NES substations throughout Greater Nashville. 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 the Greater Nashville area 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 and represents a significant investment in grid reliability and local energy infrastructure. Seven States and NES view the project as a model for future battery-focused investments across the Southeast.
