The U.S. Department of Energy will provide up to $50 million to upgrade electric transmission infrastructure in western Virginia, aiming to increase the amount of electricity existing power lines can carry as demand grows.
Energy Secretary Chris Wright announced the funding on October 16 at an Appalachian Power substation in Lynchburg, alongside Representative John McGuire and Appalachian Power President and Chief Operating Officer Brian Abraham. Appalachian Power plans to match the federal contribution, bringing the anticipated investment to at least $100 million.
Rather than building an entirely new transmission corridor, the project will combine upgrades to existing wires with technology that allows operators to make better use of available transmission capacity.
Rebuilding Lines to Carry More Power
The project will rebuild approximately 14 miles of transmission line in the Lynchburg area and install weather-monitoring sensors on four transmission lines in western Virginia.
The New London-Otter Transmission Line Rebuild Project will replace existing conductors along the route through Campbell and Bedford counties. Known as reconductoring, the process upgrades the wires within an existing transmission corridor, potentially increasing capacity without requiring a new route.
The project will also deploy dynamic line rating technology, which uses real-time information about weather conditions, including wind and temperature, to assess how much electricity transmission lines can safely carry.
Conventional line ratings typically rely on conservative assumptions about operating conditions. Dynamic ratings can allow operators to use additional capacity when conditions permit, although the available capacity varies with the weather.
Together, the two approaches are intended to increase the use of existing infrastructure while accelerating the delivery of additional transmission capacity.
290 MW of Additional Transmission Capacity
The Department of Energy estimates that the improvements will add approximately 290 megawatts (MW) of transmission capacity across Appalachian Power’s Virginia system. The department also said the approach could deliver the capacity one to four years sooner than conventional transmission upgrades.
The 290 MW figure is an estimated system-level benefit, not necessarily a fixed amount of additional capacity available at all times. Dynamic line ratings change with operating conditions, and the actual benefit will depend on how the upgraded lines perform.
The project will serve a region where Appalachian Power provides electricity to approximately 540,000 customers in western Virginia, including about 466,000 residential customers.
Increasing transmission capacity can help ease grid constraints and move more electricity through existing infrastructure. However, the upgrades alone do not guarantee lower electricity bills or eliminate the need for future grid investment.
Federal Funding Through a National Grid Initiative
The Department of Energy said the project was selected under its Speed to Power through Accelerated Reconductoring and other Key Advanced Transmission Technology Upgrades initiative, known as SPARK, which has $1.9 billion available for transmission improvements nationwide.
The department said the funding will be administered through the Defense Production Act, with Virginia Energy, Appalachian Power and other partners involved in delivering the project.
The federal government has framed grid improvements as both an energy and national security priority. The department said President Donald Trump has identified ageing and constrained electricity infrastructure as a growing concern for national defence.
The Virginia project reflects an approach that prioritizes upgrading existing transmission assets and deploying advanced technologies to increase capacity without relying exclusively on new transmission corridors.
Construction Expected to Run Through 2030
Appalachian Power expects construction on the line rebuild to begin in summer 2028 and finish by summer 2030. The final project cost has not yet been determined.
The utility’s planned matching contribution would bring the expected investment to at least $100 million if the full $50 million federal award is provided and matched as planned.
Wright said the upgrades would strengthen the electricity grid, expand available supply and help make the region more attractive to businesses.
“It’s taking existing infrastructure to deliver more electricity, allowing the creation of more jobs and lower prices,” Wright said.
Abraham said Appalachian Power aims to support regional growth while protecting affordability.
The project’s immediate objective is to increase transmission capacity through existing power corridors. Its broader impact will depend on how much additional capacity the upgrades deliver, how the system operates under changing conditions and whether the improvements help accommodate future electricity demand.
The push to expand U.S. electricity infrastructure also extends to new generation projects designed to meet rising power demand. In Indiana, Amazon, American Electric Power (AEP) and X-energy are advancing a plan for a 960 MW nuclear power plant at a former coal site, highlighting how utilities and technology companies are exploring different ways to secure reliable electricity for growing energy needs.
