The demand for transmission lines is rising due to the continuously growing population, urbanization, and industrialization worldwide. These lines are vital in connecting the remote renewable energy farms to the urban centers, ensuring a reliable and steady electricity supply. Moreover, transmission lines are responsible for the electrical grid's stability and minimizing energy losses, making them essential for power supply in developing nations.

Asia-Pacific is the most prominent region in the market due to the presence of countries such as China and India. These countries are regarded as powerhouses of electricity and are strongly focused on improving electricity transmission infrastructure in underdeveloped areas. Moreover, governments in the region are taking the initiative for the improvement of power transmission infrastructure, which fosters the demand for transmission lines in the market.

For instance, in February 2024, the Power Construction Company of China successfully completed the construction of the 220kV transmission line section (L61/64) and six new substations in the Lualaba and Upper Katanga Provinces of the Democratic Republic of Congo. The project includes two 220kV double-circuit transmission lines, L41 and L61, spanning over a distance of 190 kilometers. This development aims to alleviate electricity shortages in mining areas and improve Congo’s residents' access to power, thereby enhancing livelihoods and promoting economic development, aiding the market growth significantly.

Huge Investments in Transmission Line Setup is Amplifying Market Growth

A continuous rise in the need for electricity supply has led to a steep increase in expenditure by the government and private sectors for setting up transmission lines. Transmission lines assure a reliable supply of power, connection of renewable energy sources to the grid, and increase grid strength, thereby preventing blackouts. These lines enhance the efficiency of electricity transmission over long distances by minimizing power losses. Furthermore, well-built transmission lines aid the economic growth of a country by ensuring that the industrial areas and households have a steady power supply. This, in turn, supports the efforts aimed at achieving a safer energy environment, thereby augmenting market growth.

For instance, in July 2024, the European Union (EU) invested around USD 92.21 million in the Eastern Backbone Transmission Line Project to ensure a reliable supply of electricity in Malawi (East Africa). The funding is aligned with the Malawi 2063 objectives and EU Global Gateway Strategy. The project involves the construction of a new 132 kV line on a steel frame tower by replacing the deteriorating 42-year-old wooden pole-mounted lines. The investment will benefit domestic and agro-based industries, mining projects, and rural growth centers by increasing the reliability of power and reducing transmission losses, thereby proliferating the market expedition rate to a great extent.    

Requirement of Transmission Lines in Renewable Energy Infrastructure Is Fueling Market Growth

Transmission lines are crucial in creating a renewable energy infrastructure since they enable effective electricity transmission from generation sites to consumption centers. Countries across the globe need reliable transmission systems, which could enhance the efficacy of their grid infrastructure. Moreover, government investment in the construction of High-voltage direct current (HVDC) and AC transmission lines is necessary for the proper management to address power fluctuations. Furthermore, a proper renewable energy infrastructure reduces the reliance on fossil fuel to a great extent, allowing sustainable energy transmission worldwide, which, in turn, fuels market growth.

In June 2024, the planning approval of Central-West Orana Renewable Energy Zone (REZ) Transmission project by the Australian government marked the achievement of a huge milestone for the state of New South Wales (NSW) in renewable energy. It became the first REZ transmission project in Australia spanning over a distance of 240 km, aimed at strengthening the renewable energy infrastructure of the country. The project will facilitate the development of central transmission infrastructure to connect big-scale solar, wind, and energy storage projects, which will involve an overall investment worth USD 20 billion. Moreover, REZ has the capacity to transmit at least 4.5 gigawatts (GW) of electricity to power 1.8 million homes, thus promoting a clean energy transition.

Government Initiatives to Act as a Market Growth Catalyst

Government initiatives play a major role in the growth of the market by enhancing grid resilience, reducing transmission losses, and stimulating economic growth through attracting investments. Additionally, supportive government policies drive innovation and technological advancements, thereby ensuring transmission systems to meet the requirements of future energy demands. Governments can pave the way for a greener energy future that benefits the economy and the environment by prioritizing sustainability and efficiency.

In October 2024, the U.S. Department of Energy (DOE) announced a hefty investment of nearly USD 1.5 billion to extend its support to 4 large-scale power grid projects, namely the Smart Grid Investment Grant Program, Pacific Northwest Smart Grid Demonstration Project, Grid Modernization Initiative, and Energy Storage Demonstration Project. The main goal of the funding is to facilitate the electricity transmission infrastructure of the United States by ensuring proper renewable energy supply and improving grid reliability. Moreover, the initiative aims to strengthen the American power supply chain, ultimately leading to a more sustainable energy future.

Rise in Demand for Overhead Transmission Lines is Fostering Market Growth

Overhead lines are a cost-effective means of constructing a power transmission network which could extend over long distances. The overhead lines allow power utilities to interconnect far-flung renewable resources such as wind and solar energy farms to urban areas. Additionally, rapid technological advancements with time have enhanced the effectiveness and dependability of overhead transmission systems. Furthermore, the rise in need for enhanced grid resilience aids to the increasing preferences for overhead transmission infrastructure in modern power networks, thereby amplifying the market growth.

For instance, in June 2024, Northern Nevada (NV) Energy Inc., submitted a request to the Reno City Council to approve the construction of a new 11.9-mile long, 120 kV overhead transmission line located between Bordertown (Cold Springs Area) and California substations (Verdi area). The main aim of NV Energy’s request was to add redundancy to the existing 120 kV system that supplies bulk power to the West Reno/Vardy area to meet the government regulatory standards.

Asia-Pacific to Dominate the Global Transmission Line Market Share

Asia Pacific emerged as a key region in the transmission line market due to the presence of countries such as China, India, Japan, Vietnam, and South Korea. The countries are involved in rapid urbanization, fulfilling the rising energy demand, and investing in major infrastructure, which drives the demand for transmission lines in the region. Moreover, the governments of the aforesaid countries are prioritizing the construction of power transmission networks to boost economic growth and increase energy availability. Furthermore, efforts to integrate renewable energy and modernize old grids for proper electricity distribution are driving market expansion, which, in turn, ensures Asia-Pacific’s position as a market leader in the transmission line market.

For instance, in August 2024, Vietnam Electricity Corporation introduced the 500kV circuit-3 power transmission line, which links Quang Trach in the central province of Quang Binh and Pho Noi in the northern province of Hung Yen of Vietnam. These are crucial and urgent power transmission projects that are pivotal in increasing the power transmission capacity. The project will play a major role in improving the stability of the Vietnamese power system, enhancing the electricity supply, and decreasing the risk of overload and congestion in existing 500 kV lines, thereby ensuring national energy security.
