DOE Picks 31 Reconductoring Projects in 26 States and Puts $1.9 Billion Against 23 GW of Capacity

The U.S. Department of Energy said on September 24, 2026 that it intends to fund 31 grid-improvement projects across 26 states. DOE puts $1.9 billion of federal money behind them. Recipients add $3.35 billion of cost share, for $5.25 billion in total. The Office of Electricity runs the award under an initiative it calls SPARK, for Speed to Power through Accelerated Reconductoring and other Key Advanced Transmission Technology Upgrades.

The work is deliberately unglamorous. Recipients will reconductor or rebuild more than 1,500 miles of existing transmission line. They will deploy grid-enhancing technologies across nearly 21,000 miles more. DOE puts the combined result at more than 23 gigawatts of additional capacity, on rights-of-way that already exist, serving roughly 100 million Americans.

Reconductoring instead of greenfield

Reconductoring swaps an existing conductor for a higher-capacity one on the same towers. It avoids the siting fight and the land acquisition that stretch a new corridor across a decade or more. DOE frames SPARK around that timeline gap. The department says the approach bypasses the multi-decade schedules that new corridors require, and delivers upgrades in what it calls record time.

Catherine Jereza, assistant secretary for the Office of Electricity, said the selected projects maximize the capacity of existing lines and unlock more than 20 gigawatts of additional grid capacity. Energy Secretary Chris Wright tied the awards to the administration’s electricity-cost agenda. SPARK draws its money from the Grid Resilience and Innovation Partnerships program, so this is a reallocation inside an existing pot rather than new appropriation.

Why It Matters

If the interconnection queue is the bottleneck everyone argues about, the conductor is the bottleneck nobody photographs. More than 23 gigawatts is real capacity, and it lands on corridors that already hold easements, access roads and permits. For a load developer holding a queue position, an upgrade on an existing line is the capacity most likely to arrive on a data-center schedule rather than a transmission schedule.

The number to watch is not the $1.9 billion of federal money. It is the $3.35 billion of recipient cost share, the larger of the two halves of the $5.25 billion total. Utilities are funding most of this program themselves, and most utility capital returns through rates. Ratepayers across those 26 states will carry that spending before any of the bill savings DOE advertises show up.

What one award looks like

PPL Electric Utilities gave the clearest picture of a single selection. The Pennsylvania utility said it was picked for up to $71.5 million toward its Montour Grid Resilience and Advanced Reconductoring Project. The project rebuilds about 29.3 miles of an existing 230-kilovolt corridor serving the Susquehanna Valley, the Lehigh Valley and northeast Pennsylvania. PPL announced it alongside Secretary Wright in Allentown on September 24.

Two phrases in those announcements do a lot of work. DOE announced an intention to fund. PPL was selected to receive up to $71.5 million. Neither wording is a signed award, and federal grid programs have slipped between selection and obligation before. DOE has not published a schedule for converting the 31 selections into executed agreements.

Critical Perspective

The 23 gigawatt figure deserves a harder look than it will get. Roughly 1,500 miles of that program is physical reconductoring, where new conductor on the same towers does add firm capacity. The other 21,000 miles is grid-enhancing technologies, which mostly means dynamic line ratings and power-flow control. Those release headroom that already exists on a cool, windy day. They do not add a conductor. Rating a line higher when conditions allow is not the same asset as a rebuilt line, and DOE published one combined gigawatt number for both.

SPARK also reallocates money that GRIP already held rather than adding appropriation. That is a reasonable use of an existing pot, but it means the 31 selections compete with whatever GRIP would otherwise have funded, and DOE has not said what moved aside. Ask for three things before treating this as capacity: the per-project split between reconductoring and grid-enhancing technologies, the schedule for turning intentions into obligated agreements, and which of the 26 states carry the cost share in rate base rather than shareholder equity.
