Transmission Line Construction: Market Size & Forecast 2026

The global transmission line construction market sits at approximately USD 6.3 billion in 2025, projected to reach USD 8.7 billion by 2032, growing at a 4.7% CAGR. The market is characterized by a structural imbalance between the urgent need for transmission expansion, driven by renewable integration, electrification, and aging infrastructure, and chronic permitting delays, supply chain bottlenecks, and skilled labor shortages. While global demand points to 5,000+ miles of new high-voltage transmission annually through 2040, actual construction has lagged significantly, with only 888 miles completed in 2024. > **Analyst Take.** the consensus 4.7% CAGR for transmission construction significantly understates the actual acceleration potential. FERC Order 1920, combined with the CHIPS Act infrastructure requirements, will trigger a 12-18 month surge in project awards starting Q3 2026. Buyers
