DOE Kicks Off a Huge Investment into America’s Electric Grid

The U.S. Department of Energy’s Office of Electricity announced on September 24, 2026, that it intends to help fund 31 grid-improvement projects across 26 states under the Speed to Power through Accelerated Reconductoring and other Key Advanced Transmission Technology Upgrades (SPARK) initiative. The package totals $5.25 billion—$1.9 billion in federal funding and $3.35 billion in recipient cost-share—to expand usable transmission capacity, cut congestion, and lower electricity costs for roughly 100 million Americans.

These are selections, not yet final awards. Formal financial-assistance agreements are expected between October 2026 and January 2027, and individual project details remain subject to negotiation. SPARK is funded through the Infrastructure Investment and Jobs Act’s Grid Resilience and Innovation Partnerships (GRIP) program and reflects the Trump administration’s “Speed to Power” push to meet rising demand from data centers, industry, and electrification without waiting decades for new greenfield transmission corridors.

What SPARK Funds and Why It Matters

SPARK prioritizes two complementary approaches: physical upgrades that increase the thermal and electrical capacity of existing lines, and Advanced Transmission Technologies (ATTs) plus Grid-Enhancing Technologies (GETs) that extract more usable capacity from the same assets in real time.

Selected projects are expected to reconductor or rebuild more than 1,500 miles of transmission lines and deploy GETs across nearly 21,000 miles. Together, they are projected to make more than 23 gigawatts of additional electricity capacity available. Reconductoring typically replaces older aluminum-conductor steel-reinforced (ACSR) wire with higher-capacity advanced conductors that can carry more power on the same towers and rights-of-way. GETs include dynamic line ratings (which adjust capacity based on weather and loading), advanced power-flow controllers, topology optimization software, sensors, and devices such as STATCOMs that stabilize voltage and flows.

By staying inside existing rights-of-way, the projects avoid the siting, permitting, and construction delays that have stretched new long-distance lines into multi-decade efforts. DOE and project sponsors argue this approach also reduces congestion costs that ultimately appear on customer bills and improves resilience against wildfires, severe weather, and blackouts.

Energy Secretary Chris Wright said the announcement “reinforces the Trump Administration’s commitment to commonsense energy addition policies that lower electricity prices and strengthen our grid.” Office of Electricity Assistant Secretary Catherine Jereza added that the projects “put advanced transmission technologies to work, modernizing critical infrastructure, maximizing the capacity of existing lines, and unlocking more than 20 gigawatts of additional grid capacity.”

Flagship Interregional and Large-Load Projects

Two of the largest selections target the historically constrained East-West interconnections and major regional seams:

• The Colorado Energy Office is the prime recipient for the CO2TX project (total value about $1.2 billion, $250 million federal). Partners include Xcel Energy Services, Public Service Company of Colorado, Southwestern Public Service, and Southwest Power Pool. The work relocates and upgrades a Western-to-Eastern interconnection tie, lifting transfer capability from 210 MW toward 700 MW with a path to 2,000 MW.
• Oklahoma’s Office of Management and Enterprise Services leads the Three Corners Connection, an approximately 290–300-mile high-voltage link (up to 525 kV) running from the WECC near Pueblo County, Colorado, to the SPP Optima substation near Guymon, Oklahoma. Total project value is listed at about $832 million.

Indiana’s Office of Energy Development (or partnered entities) received roughly $175 million federal toward a $349 million effort to expand transfer capability across the PJM–MISO seam using advanced conductors, dynamic line ratings, power-flow controllers, and topology optimization. Officials project 2,000–4,000 MW of additional transfer capacity and $50–150 million in annual congestion-cost savings for ratepayers.

These interregional upgrades are intended to let surplus generation in one region serve load in another, improving resource adequacy and reducing the need to run expensive local peaking units.

Utility, Cooperative, and Public-Power Selections

A wide mix of investor-owned utilities, cooperatives, and public-power entities were selected. Examples include:

• Alabama Power’s Northeast Alabama Smart Grid Deployment ($50 million federal, ~$184 million total) to unlock capacity for data centers, manufacturers, and commercial load.
• Entergy Mississippi’s multi-state ATT deployment across Arkansas, Louisiana, and Mississippi, aimed at supporting data-center and industrial growth.
• Duke Energy Carolinas’ UNLOCK Carolinas project ($50 million federal) combining line upgrades and ATTs in areas affected by Hurricane Helene.
• PPL Electric Utilities’ Montour Advanced Reconductoring Project in Pennsylvania (~$71.5 million federal) rebuilding about 29 miles of 230 kV corridor.
• Rocky Mountain Power’s UNLOCK project serving Utah, Idaho, and Wyoming with upgrades and advanced line-rating technology.
• Eversource Energy’s Dynamic Rating Enhancement work in New England and New England Power Company’s sensor-and-modeling system for real-time ratings.

Additional named recipients include American Electric Power, CenterPoint Energy Houston Electric, Tennessee Valley Authority, Puget Sound Energy, New York Power Authority (Marcy STATCOM PowerBoost), Orlando Utilities Commission, Kit Carson Electric Cooperative (New Mexico), Arizona Electric Power Cooperative, Farmers’ Electric Cooperative of New Mexico, Four County Electric Membership Corporation (North Carolina), Basin Electric Power Cooperative (multi-state rural corridors), 1803 Electric Cooperative (Louisiana), Guam Power Authority, and others.

Smaller cooperatives received awards under a dedicated small-utility track with lower cost-share requirements. The official selected-applications document lists 31 projects; details are derived from applications and can change.

How This Benefits Grid Stability and U.S. Consumers

The U.S. grid faces simultaneous pressure from load growth (especially AI data centers), generation retirements, and limited new transmission. SPARK’s design addresses several failure modes at once:

• Capacity without new corridors. Reconductoring and GETs increase transfer capability on lines that already exist, reducing the “we can’t interconnect because the line is full” problem that delays generation and large loads.
• Congestion relief and cost reduction. Bottlenecks force operators to dispatch more expensive generation or curtail cheaper resources. Relieving those constraints lowers wholesale prices that flow through to retail bills.
• Operational flexibility and real-time ratings. Dynamic line ratings and power-flow control let operators use more of a line’s physical capability when weather and loading allow, instead of conservative static ratings.
• Resilience. Steel structures replacing wood, better monitoring, and devices that manage voltage and flows help the system ride through wildfires, storms, and equipment failures.
• Speed. Projects are expected to deliver results on a 48-month or shorter timeline rather than the 10–20-year cycle typical of new interstate lines.
• Resource adequacy and large-load interconnection. Extra transfer capability between regions and within high-growth pockets (Alabama, the Mid-South, Indiana, the West) supports both firm generation and the data-center boom without immediately requiring massive new generation plus new transmission.

DOE has emphasized that the program is intended to stabilize and optimize the existing system so America can add power faster while keeping prices in check. Whether the projected 23 GW materializes on schedule will depend on final negotiations, supply chains for advanced conductors, and execution by the utilities and state agencies that won selections.The official project list and press materials are the primary sources for award amounts and scopes; readers should treat early figures as estimates until cooperative agreements are signed.
