According to the TechSci Research report, “EHV Transmission Market – Global Industry Size, Share, Trends, Competition Forecast & Opportunities, 2020-2030F”, the global Extra High Voltage (EHV) Transmission Market was valued at USD 2.23 billion in 2024 and is expected to reach USD 3.17 billion by 2030, growing at a CAGR of 5.87% during the forecast period. The market’s growth reflects rising investments in grid resilience, renewable energy integration, and long-distance power transfer infrastructure.
Grid Resilience and Reliability: A Primary Market Driver
One of the most critical drivers of the EHV Transmission Market is the growing global emphasis on grid resilience and reliability. As power networks face increasing stress from extreme weather events, cyberattacks, and equipment failures, utilities and governments are investing in infrastructure capable of maintaining uninterrupted electricity supply.
EHV transmission systems are designed to transport large amounts of power efficiently over long distances while withstanding operational disruptions. Their ability to handle high fault currents and provide system redundancy makes them indispensable for reducing cascading failures and maintaining supply continuity.
The growing number of critical infrastructure facilities such as data centers, hospitals, and industrial hubs, which require round-the-clock electricity, is further pushing demand for robust EHV solutions. Governments are also enacting stricter regulatory frameworks to ensure resilience, compelling utilities to modernize their grids and adopt advanced EHV technologies.
Rising Threats and Economic Impact of Power Outages
The frequency and severity of power outages underscore the importance of high-performance EHV networks. In 2023, global power outages caused economic losses amounting to USD 180 billion, according to the U.S. Department of Energy. To mitigate such risks, EHV transmission projects accounted for USD 110 billion of investments in 2024, contributing to more than 70% of global grid resilience initiatives.
These investments added over 5,000 kilometers of high-capacity transmission lines worldwide, reinforcing reliability and enabling better integration of renewable energy into national grids. The scale of these projects demonstrates the economic necessity of transitioning toward more resilient and efficient power transmission systems.
Technological Complexities in Deployment
While the market outlook is positive, technological complexity remains a key challenge in the deployment of EHV systems. Modern EHV transmission must often be integrated with aging legacy grids that were not designed for such high-capacity or bi-directional energy flows.
This integration challenge can lead to:
Compatibility issues between old and new grid infrastructure.
Voltage imbalance and reactive power management difficulties.
Increased system losses if not carefully managed.
To address these challenges, utilities are upgrading substations, deploying real-time control systems, and enhancing supervisory control and data acquisition (SCADA) platforms to synchronize operations. Collaboration among utilities, regulators, and equipment manufacturers is critical for achieving seamless integration.
Furthermore, the growing role of renewable energy and electric vehicles (EVs) introduces variability and higher demand peaks. EHV systems must therefore be not only scalable but also flexible and intelligent, capable of adapting to dynamic energy flows. Advanced solutions such as High Voltage Direct Current (HVDC) within EHV frameworks are becoming essential for ensuring efficiency and stability.
End-Use Analysis: Utilities Segment Leads the Market
Dominance of Utilities
By end-use industry, the utilities segment dominates the global EHV Transmission Market and is expected to maintain its leadership through 2030. Utilities are at the core of power transmission, responsible for developing, operating, and maintaining the infrastructure that transports electricity from generation plants to end-users.
Key Drivers for Utilities
The utilities segment’s dominance is underpinned by several factors:
Rising electricity demand in urban and industrial zones.
Large-scale investments in transmission corridors and interconnectors.
The need to integrate renewable energy sources such as wind, solar, and hydropower into national grids.
Strong government mandates on energy security and sustainability.
Utilities also enjoy greater access to financing and regulatory approvals compared to industrial or commercial end-users, allowing them to execute large projects on shorter timelines. Examples include cross-border interconnections, ultra-high voltage transmission projects in China and India, and smart grid modernization initiatives in Europe.
In addition, utilities are spearheading digital substations and smart grid deployments to increase grid efficiency, predictive maintenance, and real-time visibility, further reinforcing their investment in EHV infrastructure.
