Reconductoring: The Path of Least Resistance to Fixing the U.S. Energy Grid

The report advocates for reconductoring as a primary solution to the U.S. energy grid's capacity crisis, which currently stalls 2,500 GW of clean energy projects. By replacing traditional steel-core cables with advanced composite conductors, the grid can double its transfer capacity at less than half the cost of building new lines, with installation times of 18-36 months compared to 10-15 years for new construction. The document highlights the potential for $180 billion in system savings by 2050 and a 3-4% reduction in wholesale electricity costs. It details technical improvements, such as trapezoidal wires and carbon-fiber cores, and cites successful implementations in Texas, Nevada, California, and Minnesota, as well as international adoption in Europe and Asia. The report concludes by urging policymakers to support legislation like the High-Capacity Grid Act and the REWIRE Act to incentivize the adoption of these technologies.

• The U.S. energy grid faces a severe capacity shortage, with approximately 2,500 GW of clean energy projects stalled due to lack of connectivity, while demand rises from electric vehicles, data centers, and industrial electrification.
• Reconductoring is significantly faster and cheaper than building new transmission lines; advanced conductors can be installed in 18-36 months, whereas new lines take 10-15 years, and reconductoring costs less than half as much because it avoids the need for new structures.
• Advanced conductors, such as the ACCC® conductor, improve efficiency by reducing power line losses by up to 40%, which has prevented 23 million metric tons of carbon dioxide emissions and reduced thermal power plant water consumption by 124 billion gallons.
• Implementing reconductoring could provide substantial economic benefits, including system savings of $85 billion by 2035 and $180 billion by 2050, and a 3-4% reduction in wholesale electricity costs.
• To achieve net-zero emissions by 2035, the U.S. may require up to 47,300 GW-miles of additional transmission capacity; reconductoring could provide over 60,000 GW-miles of capacity at only a 20% higher cost compared to current growth rates.
