The global transmission line market size was USD 81.39 billion in 2020. The market is expected to grow from USD 86.88 billion in 2021 to USD 138.99 billion in 2028 at a growth rate of 6.9% in the 2021-2028 period. The global COVID-19 impact has been unprecedented and staggering, with transmission line witnessing a negative demand shock across all regions amid the pandemic. Based on our analysis, the global market exhibited a decline of -9.3% in 2020 as compared to the average year-on-year growth during 2017-2019. The rise in CAGR is attributable to this market’s demand and growth returning to pre-pandemic levels once the pandemic is over.

A transmission line can be defined as an electricity transferring system that is widely used for the transmission of electrical energy from generating substations to the distribution networks. These lines are made up of four components, including inductance, resistance, capacitance, and shunt conductance. These lines can also be defined as the interconnected lines, which enable the electricity movement across the infrastructure of such systems from the generation site to the source of distribution.   

COVID-19 Pandemic to Affect Power Projects Across the World

The COVID-19 pandemic has spread in most of the countries across the world. This pandemic has impacted various business sectors, including oil & gas, logistics, hospitality transportation, aviation, and others. Governments in many countries had to keep the nations into lockdown to restrict the further spread of the virus; however, the measures impacted economies of nations severely across the globe. The outbreak of the pandemic has also disrupted supply chains as governments across several countries announced lockdowns and imposed travel bans. This leads to delay in many projects and created a shortage of labor. Many industries were not operational during the lockdown and this reduced the electricity demand from the industrial sector across the world.

Various new such projects were put on hold in various countries. The renewable sector is highly dependent on imports from other countries, mainly from China. However, the closing down of international borders led to delay in various renewable electricity generation projects.

Increasing Energy Demand to Augmentn Market Growth

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

As many countries across the world are witnessing rapid increase in electricity demand, so 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 toward the renewable sector is increasing, particularly toward such line generation. These factors drive the growth of the market over 2021-2028.


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

Smart grids are expanding across the world as the investment in smart grids 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 smart grid, the micro-grid network is also expanding immensely across the world. The increasing power consumption surges the demand for network infrastructure for electricity across the world. 

Rising Retrofit and Refurbishment of Existing Infrastructure Augmented Market Growth

Several developing countries across the world have initiated the refurbishment or replacement work in 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 in increasing efficiency along with extending the life of infrastructure. This refurbishment and retrofit of existing infrastructure drive the growth of the market.  


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 costing of such equipment. The fluctuations in steel prices also affect the market negatively. 


By Type Analysis

Underground Segment Held Dominant Market Share in 2020

By type, the market share is broken down 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. Majority of developed regions have underground installation. The underground installation of such lines does not disturb by weather conditions and it causes fewer outages than overhead. The underground lines have better appearance and also high efficiency as the chances of faults are very less. There are several developing regions working to convert their overhead lines into the underground.

The submarine segment is expected to register growth at a significant CAGR over 2021-2028. The demand for such types of such lines is increasing in the market as the installation of offshore farms is increasing across the world. According to 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 2020

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 register significant growth over 2021-2028. Urbanization is increasing along with the number of data centers across the world. This increases the demand for the high voltage segment over 2021-2028.
