The U.S. Department of Energy (DOE) has announced plans to invest approximately $581 million in 84 transmission and distribution projects across eight states in partnership with the Tennessee Valley Authority (TVA). The projects are expected to add approximately 2.5 gigawatts (GW) of grid capacity, improve electricity reliability, reduce outages and strengthen the resilience of the power system.
The funding award includes $250 million in federal support and approximately $331 million in cost-share funding from project applicants. The investments are expected to improve electricity access and reliability for around 2.58 million families and businesses while supporting approximately 800 jobs.
The initiative is being implemented under the Resilience Amplified: Multi-Market Grid Interconnection Initiative, part of the DOE’s Grid Resilience and Innovation Partnerships (GRIP) programme. The programme aims to strengthen electricity infrastructure, improve grid performance and ensure consumers have access to affordable, reliable and secure electricity.
According to the DOE, the projects will help reduce transmission congestion, improve operational efficiency and increase the capacity of existing electricity infrastructure. The investments are also intended to help utilities deliver electricity more effectively to areas experiencing growing demand, while reducing the risk of costly power disruptions.
U.S. Deputy Secretary of Energy James P. Danly said the investments would help address the need for stronger transmission infrastructure to support economic growth and rising electricity consumption. He highlighted the importance of expanding and improving transmission networks to make better use of existing infrastructure and deliver affordable and reliable power to consumers.
Office of Electricity Assistant Secretary Katie Jereza said the initiative would bring TVA and local utilities together to reduce outages and improve electricity delivery. She added that strengthening the grid would help households experience fewer disruptions and provide businesses with a more dependable electricity supply.
The latest award builds on the DOE’s earlier selection of TVA for the Speed to Power through Accelerated Reconductoring and other Key Advanced Transmission Technology Upgrades (SPARK) programme. The programme focuses on upgrading existing transmission infrastructure using advanced technologies to increase capacity and reduce congestion.
Together, the GRIP and SPARK projects represent nearly $741 million in planned grid investment for TVA. This includes approximately $329.8 million in federal funding, with the combined projects expected to add more than 4,300 megawatts (MW) of additional grid capacity.
Under SPARK, TVA plans to upgrade approximately 125 miles of existing transmission lines across Tennessee, Alabama and North Carolina. The $159.7 million project will use advanced conductors and grid-management technologies to increase transmission capacity by approximately 1,900 MW and reduce congestion across the network.
The projects form part of broader efforts to modernise electricity infrastructure and improve the ability of transmission networks to accommodate increasing power demand. Upgrading existing lines and improving grid management can help utilities transfer electricity more efficiently without relying entirely on the construction of new transmission corridors.
However, the final federal funding arrangements, project scope, implementation schedules and other award conditions remain subject to the execution of DOE agreements and applicable environmental, permitting, regulatory and Tribal reviews.
