Washington, D.C. – Congresswoman Julie Fedorchak’s (R-ND) High-Capacity Grid Act (H.R. 6633) today passed the U.S. House of Representatives unanimously. The legislation will modernize America’s transmission system by requiring the use of best-available transmission conductors for new and rebuilt interstate transmission lines. The House Energy and Commerce Committee advanced the bill unanimously in July 2026 by a 49-0 vote.

"America's electricity demand is growing at the fastest pace in decades. To meet this demand, we must optimize our existing transmission infrastructure," Fedorchak said. "The High-Capacity Grid Act is a commonsense solution that will help us move more electricity over existing rights-of-way, improve grid reliability, and—most importantly—does so at the lowest possible costs."

The High-Capacity Grid Act directs the Federal Energy Regulatory Commission (FERC) to establish a best-available transmission conductor standard for interstate transmission projects.

The legislation will:

• Promote the use of the highest-capacity, most efficient conductors available for new interstate transmission projects and rebuilds.
   
• Increase transmission capacity within existing rights-of-way to connect and carry more electricity, reducing the need for additional corridors and new transmission lines.
   
• Improve grid reliability at the lowest possible costs for consumers.
   
• Promote cost-effective utility investments through the deployment of proven, high-performance transmission technologies.
