Funding from the government due to the Bipartisan Infrastructure Law and similar foreign grid modernization initiatives is also contributing to this growth in baseline reconductoring capability.

Restraints: High Composite Core Material Costs and Installation Complexity

While the relatively higher initial cost of composite core and carbon fiber conductor systems in comparison to traditional ACSR conductors remains a true limitation for accelerated growth in the market since most utilities facing capital limitations tend to opt for the cheaper alternative despite its obvious long-term advantages, the implementation of the most sophisticated reconductoring solutions has taken place predominantly in case of financially solid transmission utilities.

Meanwhile, the complex nature of installation remains another hurdle that must be overcome in order to facilitate further reconductoring, since reconductoring of existing towers with increased capacity conductors is likely to involve evaluation of structure, live line operations, and specific rigging, thus making the process take much longer than mere replacement of existing conductors. The solution lies in adequate EPC workforce and proven structural load models, which is a lengthy process.

Opportunities: Data Center-Driven Demand and Regional Transmission Planning Reform

The fast-growing energy requirements for data centers and electricity generated by the electrification process presents an opportunity for vendors whose products can be used for reconstruction to get ahead of the situation since utilities are increasingly using reconductoring to alleviate interconnection queue backlog at a faster rate compared to when they construct new lines. Manufacturers that have the ability to provide field-tested composite conductor products, such as CTC Global's ACCC Conductor are likely to dominate in this opportunity.

A second significant opportunity exists in the implementation of FERC Order 1920 and similar changes in regional transmission planning which explicitly support reconductoring in order to offer a faster solution than the construction of new lines. Suppliers who can perform feasibility studies and reconductoring on a turnkey basis like Grid Strategies LLC which is involved in advocating for CTC Global are expected to benefit disproportionately from this opportunity.
