Super Grid Market Report 2026

The super grid market size has grown rapidly in recent years. It will grow from $21.84 billion in 2025 to $24.45 billion in 2026 at a compound annual growth rate (CAGR) of 11.9%. The growth in the historic period can be attributed to rising electricity demand growth, government renewable energy mandates, aging transmission infrastructure upgrades, cross-border energy trade agreements, industrialization and urbanization expansion.

The super grid market size is expected to see rapid growth in the next few years. It will grow to $38.68 billion in 2030 at a compound annual growth rate (CAGR) of 12.2%. The growth in the forecast period can be attributed to large-scale offshore wind investments, green hydrogen production expansion, energy transition and decarbonization targets, smart grid and automation funding, regional energy security initiatives. Major trends in the forecast period include cross-border grid interconnection expansion, ultra high voltage transmission deployment, renewable energy corridor development, advanced grid stability and power flow control systems, integration of large-scale energy storage solutions.

The rising demand for cross-border electricity transmission is expected to propel the growth of the super grid market going forward. Cross-border electricity transmission refers to the movement of electrical power across national borders through interconnected transmission systems to facilitate electricity trade, grid balancing, and reliable energy supply between neighboring countries. The growing demand for cross-border electricity transmission is largely driven by the rapid expansion of renewable energy generation across multiple regions, which introduces supply variability and increases dependence on cross-border energy exchanges for grid stability, along with broader initiatives to strengthen energy security and integrate regional electricity markets. Super grids support this rising demand by enabling high-capacity, long-distance, HVDC-based, and digitally managed transmission infrastructure that allows efficient power flow between national grids. For instance, in October 2024, according to Ember Energy, a UK-based climate and energy think tank, Europe’s power sector is rapidly transitioning toward renewable sources, with the REPowerEU plan targeting 72% of electricity generation by 2030, up from 44% in 2023, driven by wind and solar power, whose combined share is projected to increase from 27% in 2023 to 55% by 2030. This fast expansion of variable renewable energy is intensifying grid balancing needs and interconnector usage across European power markets, reinforcing the necessity for enhanced cross-border transmission capacity and super grid infrastructure. Therefore, the increasing demand for cross-border electricity transmission is driving the growth of the super grid market.

Leading companies in the super grid market are concentrating on developing innovative products such as high-voltage direct current (HVDC) transmission systems that enable efficient long-distance and multinational power transfer. High-voltage direct current (HVDC) transmission systems are advanced electrical transmission technologies that allow large amounts of electricity to be transmitted over long distances with lower losses and improved controllability compared with traditional alternating current (AC) systems, making them ideal for cross-border interconnections. For example, in June 2023, Hitachi Energy, a Switzerland-based energy technology company, secured an order to supply HVDC converter stations for the France-Spain Biscay Gulf interconnection, a subsea link capable of transmitting 2,000 MW of electricity over approximately 400 km, featuring compact converter technology, low electrical losses, and enhanced grid stability and power quality.

In January 2024, Hitachi Energy, a Switzerland-based company specializing in HVDC systems, power grid infrastructure, grid integration technologies, and power electronics, acquired COET for an undisclosed value. Through this acquisition, Hitachi Energy sought to enhance its technical expertise and manufacturing capacity in high-power electronics, supporting the growth of grid-edge solutions and scalable electrification aligned with next-generation super grid and electric mobility infrastructure. COET is an Italy-based company providing high-power converters, rail traction DC systems, electric mobility power equipment, and AC/DC solutions for industrial and grid-edge use.

Tariffs have created mixed effects on the super grid market by increasing the cost of high voltage cables, transformers, converters, and control equipment, thereby raising project capital expenditure and slowing deployment timelines in cost-sensitive regions. Asia-Pacific and parts of Europe are most affected due to their heavy dependence on imported electrical components and cross-border supply chains, particularly within ultra high voltage and energy storage segments. However, tariffs are also encouraging domestic manufacturing, regional supplier diversification, and localized production of grid equipment, which is gradually strengthening supply chain resilience and fostering technological innovation in national power infrastructure projects.

A super grid is a large-scale electricity transmission network designed to interconnect multiple regional or national power grids over long distances. It enables the efficient transfer of large amounts of electricity, especially from renewable energy sources, across wide geographic areas. It helps to improve grid reliability, energy security, and large-scale renewable energy integration.

The primary components of super grids include converters, transformers, high-voltage cables, energy storage, and other components. Converters refer to equipment that converts electrical power from one form to another, enabling efficient transmission and integration across the grid. The different types involved include high voltage grid, extra high voltage grid, ultra high voltage grid, and other grid types, with voltage levels classified into high voltage, extra high voltage, and ultra high voltage. The various applications involved include renewable energy integration, grid interconnection, offshore wind power, and other applications. The end users of super grids include utilities, industrial, commercial, and other end users.

The super grid market consists of sales of high voltage transmission lines, substations, transformers, power control systems, grid management software, and monitoring and protection equipment. Values in this market are ‘factory gate’ values, that is, the value of goods sold by the manufacturers or creators of the goods, whether to other entities (including downstream manufacturers, wholesalers, distributors, and retailers) or directly to end customers. The value of goods in this market includes related services sold by the creators of the goods.

The market value is defined as the revenues that enterprises gain from the sale of goods and/or services within the specified market and geography through sales, grants, or donations in terms of the currency (in USD unless otherwise specified).

The revenues for a specified geography are consumption values that are revenues generated by organizations in the specified geography within the market, irrespective of where they are produced. It does not include revenues from resales along the supply chain, either further along the supply chain or as part of other products.
