Medium Voltage Cable and Accessories Market Analysis

The rising need for electricity supply is driving the medium voltage cable and accessories market growth. The demand for more electricity is increasing due to the surging population and industrialization in developing economies. The rising urban population has also resulted in increased construction activities in commercial, residential, industrial, infrastructure, and other sectors. In Q2 of 2023, the construction of an electric vehicle battery manufacturing plant started in Michigan, which is expected to be completed by Q4 of 2025. Such construction activities directly increase the need for electricity generation and distribution, which is surging the demand for medium voltage cables and accessories. The rising focus on power generation through renewable energy sources has further resulted in the development of new power grids and distribution lines.

Medium Voltage Cable and Accessories Market Overview

A medium voltage cable distributes electricity from power substations to transformer stations. It has a minimum power rating of 1kV and goes up to 69kV. Medium voltage cables and accessories are used for electricity supply to commercial and residential buildings as well as industrial distribution circuits. They have indoor use in power supply stations and outdoor use in cable ducts, underground, and cable trays for industrial buildings, switchboards, and power stations. They are also used in pulp and paper mills, steel mills, textile mills, petrochemical plants, water and sewage treatment facilities, railroads, mines, and electrical utility generating plants. Medium voltage cable accessories such as cable terminations, cable joints, and connectors are designed to connect, protect, and support medium voltage cables for single-core or three-core.

Medium Voltage Cable and Accessories Market Drivers and Opportunities

Increasing Need to Upgrade Antiquated Power Distribution Networks

According to the National Oceanic and Atmospheric Administration report, the US has witnessed weather and climate disasters worth billions of dollars in 2023. In just the first four months of 2023, the total cost of these disasters surpassed US$19 billion, with US$ 3.5 billion attributed to flooding in California. Maui firestorm, extreme flooding in California and New England, Hurricane Idalia's category four winds battering the Gulf Coast, and devastating hailstorms and tornados throughout the central US are among the tragic events. In 2024, deadly floods and storms in Europe affected more than 400,000 people. Such major challenges that occurred due to the changing climate increase the reliability of the electricity grid. However, electric grids were built in the 1960s and 1970s, particularly in the US. Automation and emerging technologies, such as the adoption of AI and ML in smart grids, have enhanced the system. The deteriorating infrastructure is struggling to meet modern electricity needs, such as renewable energy resources and growing building and transportation electrification. For instance, 70% of transmission lines are over 25 years old and are approaching the end of their typical 50–80-year lifespan. According to data from the US Energy Information Administration, US electricity customers were without power for slightly longer than seven hours on average in 2021. Such aging infrastructure results in frequent failures, inefficiencies, and safety risks.

Medium voltage cables transmit electricity from substations to consumers, particularly in urban and industrial areas, and are integral in maintaining grid stability. Replacing outdated cables with modern, more efficient medium voltage cables is essential to ensure that power is transmitted securely and without interruption. Medium voltage cables with improved insulation, durability, and thermal resistance are being developed, enabling utilities to replace aging cables with higher-performing solutions. Thus, the increasing need to upgrade outdated power distribution networks drives the market growth.

Rising Investments in Renewable Energy

According to the Renewables 2024 Global Status Report Collection, investment in renewables in the US jumped 60% in 2023 to reach US$ 92.9 billion. Wind power experienced much higher growth (up 174.3% to US$ 37.1 billion in 2023). In October 2024, Canada’s Minister of Energy and Natural Resources announced an investment of CAD$ 500 million (US$ 363.5 million) in the Smart Renewables and Electrification Pathways program Utility Support Stream. This funding was planned to be awarded to projects that upgrade existing assets, increase grid reliability, add new renewable energy resources, and help accommodate soaring power demand. In Europe, investment in renewable energy projects increased by 42.9% in 2023 to US$ 134.4 billion. In the UK, renewable energy investment surged more than sixfold to US$ 23.2 billion, the highest level in the area. The majority of this gain was in wind energy, which received a boost this year when the government announced a 66% increase in maximum pricing for offshore wind auctions. Germany ranked second in investment (up 35% to US$ 20.4 billion), followed by Spain (up 14.4% to US$ 18.5 billion). The Czech Republic (up 246%), Denmark (up 172%), and Bulgaria (up 145%) had the fastest growth rates in renewable energy investment in Europe, although starting at lower levels.

The governments of nations are investing in wind and solar power plant construction. Among the major renewable energy projects carried out worldwide are:

• Kitty Hawk Offshore Wind Farm: A 122,405-acre offshore wind farm is being planned for an area 39 nautical kilometers off the coast of Kitty Hawk, North Carolina. The area is ideal for such a farm, with wind speeds averaging 32kmph, ~80m above the ocean's surface. The project is in the planning stages, but it is expected to begin selling power to the nearby states by 2030.
• Texas Mariah Onshore Wind Farm: It is a 10,000 MW wind farm project that is planned to be constructed across the Parmer, Sherman, and Dallam counties. Started in 2022, the project is still under development.
