Transmission Line Market Size, Share, and Industry Analysis, By Type (Overhead, Underground, and Submarine), By Voltage (130kV-220kV, 221kV-660kV, and Above 660kV), By Application (Industrial and Utility), and Regional Forecast, 2024-2032

The global transmission line market size was valued at USD 99.14 billion in 2023. The market is projected to grow from USD 105.98 billion in 2024 to reach USD 158.62 billion by 2032, exhibiting a CAGR of 5.2% during the forecast period.

A transmission line can be defined as an electricity transferring system widely used to transmit electrical energy from generating substations to the distribution networks. These lines comprise four components: inductance, resistance, capacitance, and shunt conductance. These lines can also be defined as interconnected lines, enabling electricity movement across the infrastructure of such systems from the generation site to the distribution source.   

The global COVID-19 impact has been unprecedented and staggering, with transmission lines witnessing a negative demand shock across all regions amid the pandemic. The outbreak of the pandemic has also disrupted supply chains as governments across several countries announced lockdowns and imposed travel bans. This led to delays in many projects and created a shortage of labor. Many industries were not operational during the lockdown, reducing the electricity demand from the industrial sector worldwide.

Transmission Line Market Trends

Increasing Energy Demand to Augment Market Growth

Energy consumption in Asia Pacific, Europe, and other regions has been increasing widely. The main reasons behind the strong increment in power consumption are the growth of the manufacturing sector, economic development, increasing population, and increasing data centers. Developing regions, in particular, are experiencing high electricity demand owing to the expansion and development of infrastructure. Industrialization, urbanization, and rising living standards increase the demand for electricity generation.

As many countries worldwide are witnessing a rapid increase in electricity demand, to fulfill such demand, these countries are increasing their power generating capacity either by expanding the generating capacity of existing ones or by installing new plants. In addition, pollution is also widely increasing, for which governments in many countries imposed stringent carbon emission norms. Therefore, the focus on the renewable sector is increasing, particularly toward such line generation. These factors drive the growth of the market over 2024-2032.

Transmission Line Market Growth Factors

Expansion of Smart Grids and Micro-grids Network Propel Growth in the Market

Smart grids are expanding worldwide as the investment in smart grid networks is widely increasing. Governments are also focusing on smart grid expansion in several countries. The investment in cross-border grid networks is also increasing across the world. Along with the smart grid, the micro-grid network is expanding immensely worldwide. The increasing power consumption surges the demand for network infrastructure for electricity worldwide. 

According to the International Energy Association, the European Commission presented the EU action plan for the digitalization of the energy system at the end of 2022. The Commission expects about USD 633 billion of investments in the European electricity grid by the end of 2030. USD 184 billion will be used for digitalization, including automated grid management, digital technologies for metering, and smart meters. Similarly, Asian countries are investing in smart grid power distribution. For instance, in 2022, India launched a USD 38 billion scheme to support the power distribution players and improve distribution infrastructure in the country. 

Rising Retrofit and Refurbishment of Existing Infrastructure Augmented Market Growth

Several developing countries worldwide have initiated refurbishment or replacement work on the existing transmission infrastructure. This increases the demand in the market as the existing infrastructure is aging, and it somehow does not provide maximum efficiency. The refurbishment or retrofit of the existing infrastructure helps increase efficiency and extend the life of the infrastructure. This refurbishment and retrofit of existing infrastructure drive the growth of the market.  

As per the International Energy Agency, in 2022, the U.S. announced the Grid Resilience Innovative Partnership (GRIP) Program, along with a funding opportunity of USD 10.5 billion to support the upgradation and expansion of U.S. electric grids, which involved the digitalization of power system using smart grid and other advanced technologies. Countries such as China, India, and Japan focus on upgrading their power systems in the Asia Pacific. For instance, China plans to modernize and expand its power grid system with USD 442 billion in investments by 2025. Similarly, in 2022, Japan announced a funding program of USD 155 billion to promote revamping the existing power infrastructure and investments in smart power grids. 

RESTRAINING FACTORS

Higher Dependency on Import May Hinder Market Growth

The transmission lines and towers involve the high use of raw materials such as cables, steel, and alloys. Many countries across the world are majorly dependent on the import of such raw materials from other countries. This restricts the growth of the market as the import and export regulations fluctuate, which impacts the overall cost of such equipment. The fluctuations in steel prices also affect the market negatively.  

Transmission Line Market Segmentation Analysis

By Type Analysis

Underground Segment Held Dominant Market Share in 2023

The market share is broken down by type into underground, overhead, and submarine. The underground segment is expected to dominate the market share across the world. The developed regions such as North America and Europe have maximum such lines under the ground. The majority of developed regions have underground installations. The underground installation of such lines is not disturbed by weather conditions, and it causes fewer outages than overhead. The underground lines have a better appearance and high efficiency as the chances of faults are very low. Several developing regions are working to convert their overhead lines into the underground.

The submarine segment is expected to grow significantly over 2024-2032. The demand for such lines is increasing in the market as offshore farm installation is increasing worldwide. According to the Global Wind Energy Council, offshore wind energy has registered a new installation of 35 GW in 2020. The increasing installation of offshore wind energy increases the demand for the submarine segment.  

By Voltage Analysis

220kV – 660kV Segment Led the Global Market Share during 20203

Based on installation, the market is split into 130kV – 220kV, 221kV – 660kV, and above 600kV. The 221kV – 660kV segment has dominated the market in 2020. The demand for transmission networks is increasing due to increasing demand for electricity in the market. The higher transmission line voltages reduce the transmission line losses.

The above 660kV segment is expected to grow significantly over 2024-2032. Urbanization is increasing along with the number of data centers across the world. This increases the demand for the high voltage segment over 2024-2032.
