The Department of Energy opens 1.9 billion dollars in money to upgrade power lines that already exist, not build new ones

Money to upgrade power lines that already exist

On March 12, 2026, the Department of Energy opened SPARK, Speed to Power through Accelerated Reconductoring and other Key Advanced Transmission Technology Upgrades, a 1.9 billion dollar funding opportunity for money to upgrade power lines that already exist rather than build new ones. Reconductoring means replacing the wire strung inside an existing transmission line, the high voltage line that carries power over long distances, with a wire that can carry more current on the very same towers, skipping the years of siting and permitting a brand new line would need. The opportunity splits into 3 categories. Up to 427 million dollars funds grid resilience projects, work that helps the grid keep running through storms and other disruptions. Up to 614 million dollars funds smart grid projects, the software and sensors that let a utility see and control the power flowing through its lines in real time. Up to 862 million dollars funds grid innovation projects, new equipment for moving more power through wires the grid already has. Eligible applicants include states, grid operators, tribes, local governments and utilities, and full applications are due May 20, 2026, with the Department anticipating project selections in August 2026.

What this kind of upgrade already delivers

What reconductoring and similar upgrades can actually do is already on the ground in western Pennsylvania. A 19.7 million dollar grant from an earlier round of the same program let Duquesne Light Company add sensors that measure, in real time, how much power a line can safely carry, a technique called dynamic line rating, and the utility says the deployments showed a potential 25% increase in transmission line capacity on wires that were already standing. WIRES Executive Director Larry Gasteiger summed up why utilities keep applying.

Which office actually runs the money

SPARK is administered by the Department of Energy Office of Electricity, not the Grid Deployment Office the program page still points toward. The wider Grid Resilience and Innovation Partnerships program that SPARK belongs to still carries the old Grid Deployment Office name in its own web address, but the Department states a 2025 reorganization moved most of that office into the Office of Electricity. Office of Electricity Assistant Secretary Katie Jereza tied the funding to a broader goal.

The third and smallest round of a bigger program

SPARK is the third round of the 10.5 billion dollar Grid Resilience and Innovation Partnerships program, after rounds that made up to 3.46 billion dollars available in 2023 and about 4.2 billion dollars available in 2024. Adding all 3 rounds as the Department itself states them, 3.46 billion, 4.2 billion and 1.9 billion, comes to 9.56 billion dollars announced so far, a MAOWCE calculation, leaving roughly 940 million dollars of the total program still unannounced. No SPARK projects have been selected yet. The Department describes selections as anticipated for August 2026, not delivered.
