Project Overview

Dumplin Valley Energy Storage (Dumplin Valley) is ideally located on 25 acres of land near New Market, Tennessee to be developed adjacent to TVA’s transmission grid. The facility’s location near high electricity demand, and flexibility to perform grid balancing services to support the reliability of TVA’s grid and Jefferson County.  Modernizing the grid to improve resilience in turn improves quality of life and regional economic development, enhancing prosperity for the community in Eastern Tennessee.

Situated directly adjacent to TVA’s existing Dumplin Valley 161kV Substation, the site will have no adverse environmental impacts. The Dumplin Valley facility site is an optimal location for new energy infrastructure as it will eliminate the need for long transmission lines to connect it to the existing power grid and is a conducive use to the surrounding infrastructure.
