Meshed Offshore Grid Market Report 2026

The meshed offshore grid market size has grown rapidly in recent years. It will grow from $6.31 billion in 2025 to $7.29 billion in 2026 at a compound annual growth rate (CAGR) of 15.6%. The growth in the historic period can be attributed to growth in offshore wind farms, early hvdc projects, grid congestion challenges, renewable energy mandates, cross border power trading.

The meshed offshore grid market size is expected to see rapid growth in the next few years. It will grow to $13.15 billion in 2030 at a compound annual growth rate (CAGR) of 15.9%. The growth in the forecast period can be attributed to large scale offshore wind expansion, need for grid flexibility, rising interconnection projects, demand for resilient transmission, government backed offshore corridors. Major trends in the forecast period include multi terminal offshore transmission networks, integrated offshore converter platforms, cross border offshore power links, advanced grid protection coordination, offshore grid monitoring systems.

The rapid expansion of offshore wind is expected to drive the growth of the meshed offshore grid market in the coming years. Offshore wind expansion refers to the development and deployment of offshore wind farms to increase renewable electricity generation and support decarbonization initiatives. Offshore wind expansion is accelerating due to the growing demand for clean energy to reduce carbon emissions and replace fossil fuels. Meshed offshore grids support offshore wind expansion by enabling flexible power routing between wind farms and countries, improving grid stability, and facilitating the integration of additional offshore capacity. For example, in January 2025, according to Norton Rose Fulbright LLP, a UK-based law firm, on 31 July 2024, the UK government increased the AR6 budget by £500 million ($0.615 billion) to £1.5 billion ($1.845 billion), seven times the AR5 allocation, with £1.1 billion ($1.353 billion) designated for offshore wind, representing a £300 million ($0.369 billion) increase and the largest rise among AR6 sectors. Therefore, the rapid offshore wind expansion is driving the growth of the meshed offshore grid market.

Companies operating in the meshed offshore grid market are focusing on developing innovative solutions, such as pioneering hybrid offshore wind initiatives to integrate offshore wind farms with cross-border interconnections, enhance grid flexibility, and enable efficient multi-country power transmission. Pioneering hybrid offshore wind initiatives refer to projects that combine offshore wind farms with interconnectors and grid infrastructure to simultaneously generate renewable power and transmit electricity between multiple countries through a shared offshore network. For example, in September 2025, the EU granted €645.2 million ($0.75 billion) to the Bornholm Energy Island project, a pioneering hybrid offshore wind initiative in Denmark's Baltic Sea. This funding, under the Connecting Europe Facility (CEF) Energy program, supports Denmark's Energinet and Germany's 50Hertz in building infrastructure to integrate 3 GW of renewable electricity for both nations.

In April 2023, National Grid Plc, a UK-based utilities company, partnered with TenneT Holding BV to develop and enhance cross-border offshore grid infrastructure supporting large-scale offshore wind integration in the North Sea. This partnership aims to improve cross-border electricity interconnection, strengthen grid resilience, optimize power flow management, and enable efficient, large-scale integration of offshore wind energy across the North Sea region. TenneT Holding BV is a Netherlands-based transmission system operator providing meshed offshore grid solutions.

Major companies operating in the meshed offshore grid market are Equinor ASA, Hitachi Energy Ltd., National Grid plc, Schneider Electric SE, Mitsubishi Electric Corporation, Siemens Energy AG, GE Vernova Inc., ABB Ltd., Sumitomo Electric Industries Ltd., Saipem S.p.A., Prysmian S.p.A., Nexans S.A., Amprion GmbH, Subsea 7 S.A., TenneT TSO B.V., LS Cable & System Ltd., Elia Group SA/NV, Aker Solutions ASA, Van Oord N.V., NKT A/S, and Fugro N.V.

Tariffs on high voltage cables, offshore substations, converters, and power electronics are impacting the meshed offshore grid market by increasing capital costs for grid developers and utilities. Hardware heavy segments such as hvdc systems and offshore platforms are most affected, especially in europe and asia pacific where cross border sourcing is common. Higher import duties can delay project timelines and raise overall project budgets. However, tariffs are also encouraging regional manufacturing of grid components and localized supply chains. This supports domestic electrical equipment manufacturers and offshore engineering firms.

This meshed offshore grid market research report delivers a complete perspective of everything you need, with an in-depth analysis of the current and future scenario of the industry.

A meshed offshore grid is an interconnected network of offshore transmission lines that links multiple offshore wind farms and other energy assets, enabling efficient electricity sharing and routing before delivery to onshore power systems. It allows power to be redirected among facilities during outages and helps reduce grid congestion by optimizing the flow of renewable energy across long distances. This grid architecture supports large-scale offshore wind integration and strengthens the resilience and flexibility of overall power transmission infrastructure.

The main components of meshed offshore grid are hardware, software, and services. Hardware refers to the physical equipment and devices employed to construct and operate the offshore grid, including transformers, substations, and transmission lines. These grids utilize various technologies, including high voltage direct current (HVDC) meshed grids, high voltage alternating current (HVAC) meshed grids, multi-terminal DC (MTDC) systems, and hybrid systems, and are applied across multiple applications, including offshore wind integration, cross-border interconnection, grid stability, and other applications. These solutions are delivered through multiple sales channels or contract models, including direct sales, contract-based sales, and project-based sales, and serve various end-users, including utilities, independent power producers, and other end-users.
