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.
