Electricity Transmission Infrastructure Market Analysis 2030

Industry Overview

The global Electricity Transmission Infrastructure Market size was valued at USD 389.28 billion in 2024, and is anticipated to reach USD 408.08 billion in 2025 and is predicted to reach USD 408.08 billion by 2030 with a CAGR of 4.83% from 2025-2030. 

The market is experiencing robust growth, driven by rising energy consumption, surging electricity demand and the accelerating adoption of renewable energy sources that necessitate network expansion. Massive investments in grid capacity and modernization initiatives backed by supportive government policies and public private partnerships are reinforcing the need for stronger, more resilient transmission systems. 

Technological advancements in digital twins, dynamic line rating and advanced conductors are enhancing grid efficiency, reliability and scalability, while smart grid integration and real time monitoring solutions open significant future growth opportunities. 

However, complex regulatory frameworks and escalating compliance costs continue to challenge project timelines and increase capital expenditure. Despite these hurdles, ongoing innovation in grid modernization and the transition to a cleaner energy mix promise to unlock long term value and global deployment prospects.

Rising Demand for Energy Consumption Propels the Growth of the Market

The rising energy demand is major driver of the market, driven by ongoing population growth resulting in higher energy consumption across residential, commercial and industrial purposes. As per the report published by International Energy Agency (IEA) in July 2024, predicts that global electricity consumption will grow rapidly over the 2024-2025 period, with a 4% increase expected in 2024. This surge in demand necessitates the expansion and upgrading of transmission infrastructure to effectively supply power to growing urban areas and developing regions.

Increasing Adoption of Renewable Energy Sources Drives the Demand for Expansion

Increasing adoption of renewable energy sources such as wind, solar and hydro is a significant driver of electricity transmission market. The integration of these sources requires expansion and enhancement of transmission networks for connecting them to main grid. 

For instance, in December 2023, Adani Energy Solutions (AESL) undertook a major project to evacuate 7GW of renewable energy from the Khavda Renewable Energy (RE) park in Gujarat involving construction of 301 km transmission line. This initiative represents a broader effort to integrate renewable energy into the grid, highlighting the role of robust transmission infrastructure in supporting sustainable energy transitions.

Surging Electricity Demand Further Fuels Network Expansion

Growing electricity transmission infrastructures worldwide for efficiently distributing power from generation plants to end users is driving market growth by increasing demand for equipment and services, attracting investments and encouraging technological advancements. 

For example, in January 2024, Mauritania received USD 289 from African Development Bank for the development of solar power plants and improve its energy system. Such expansions enhance energy distribution, facilitates renewable energy integration, and promotes economic growth by providing reliable power to expanding industrial, commercial, and residential areas, thereby driving the electricity transmission infrastructure market growth.

Regulatory Challenges and Compliance Costs Hinders Market Expansion

High capital costs pose a significant barrier to new projects in the market because building and upgrading high voltage lines and substations demands substantial upfront investment that many developers and utilities find difficult to secure. Exorbitant equipment and construction expenses coupled with extended lead times for specialized components can stretch procurement schedules and inflate overall budgets. As a result, project timelines are often delayed or scope reduced, hampering the pace of grid expansion even as demand for reliable, modern transmission networks continues to rise.

Technological Advancements in Grid Modernization Creates Future Growth Opportunities

On the contrary, the growing advancements in grid modernization is contributing to the market growth as it involves upgrading outdated systems with advanced technologies such as smart grids and high-voltage direct current (HVDC). For example, in April 2024, Tantalus Systems planned to modernize electrical grid     in three U.S. states for upgrading their technology using new system called Tantalus Grid Modernization Platform. These enhances efficiency, reliability and capacity to manage higher energy loads.
