Global EHV Transmission Market Size Study & Forecast, by Range (800 kV – 1500 kV, 1500 kV – 3000 kV, and Above 3000 kV), Application (Subsea Transmission, Underground Transmission, Overhead Transmission), and Regional Forecasts 2025–2035

The Global Extra High Voltage (EHV) Transmission Market is valued at approximately USD 17.87 billion in 2024 and is poised to grow at a CAGR of more than 5.00% during the forecast period of 2025 to 2035. As the global demand for efficient long-distance power transmission intensifies, the need for EHV infrastructure has become pivotal to modernizing power grids. EHV transmission systems, capable of transferring electricity over vast distances with minimal losses, are instrumental in ensuring energy reliability and sustainability. With the exponential rise in power generation from both conventional and renewable sources, particularly in remote areas, utilities and governments worldwide are increasingly shifting their focus towards robust EHV networks to bridge the gap between energy production and consumption centers.

In recent years, rising integration of renewable energy assets—especially offshore wind and solar farms—into national grids has underscored the significance of advanced EHV technologies. These high-capacity transmission lines are crucial to curbing transmission losses and accommodating bulk power flows over extended distances. Moreover, the surge in subsea and underground transmission initiatives across continents like Europe and Asia Pacific is accelerating the adoption of EHV systems. Technological advancements, such as high-temperature superconductors and real-time digital monitoring, are further enhancing transmission stability, efficiency, and responsiveness—opening new avenues for market expansion. Additionally, the global push toward energy decarbonization, coupled with investments in smart grid development, is reinforcing the need for reliable, scalable, and high-voltage transmission infrastructure.

Regionally, North America commanded a substantial market share in 2024, fueled by strategic infrastructure upgrades, interconnection projects, and decarbonization mandates spearheaded by both federal and state governments. The United States continues to lead with initiatives aimed at reinforcing grid resilience against climate-induced disruptions while enabling smoother integration of renewables into its national transmission backbone. Meanwhile, the Asia Pacific region is projected to grow at the fastest pace over the forecast timeline, driven by energy access programs, rapid industrialization, and large-scale investments in grid modernization in countries such as China, India, and Japan. Europe also plays a vital role in the global landscape, with its cross-border energy transmission goals and transition toward a pan-European supergrid that can efficiently channel renewable energy across member states.
