The global subsea power cable market was valued at $11.28 billion in 2024 and is projected to grow to $18.56 billion by 2032, registering a compound annual growth rate of 6.45 per cent during the forecast period.
This trajectory highlights the infrastructure’s expanding role in supporting offshore energy developments, where wind power generation already accounts for 59 per cent of applications and oil and gas operations continue to integrate shore-based power solutions.
According to a Fortune Business Insights report, the primary growth drivers centre on the electrification of offshore oil and gas facilities together with the need to enhance grid stability and climate resilience.
The oil and gas segment is forecast to expand at a CAGR of 4.43 per cent, reflecting sustained adoption of power-from-shore systems.
The Utsira High Power Hub Project in Norway illustrates this shift, delivering increased shore power capabilities that reduce emissions from offshore platforms.
At the same time, the trend toward greater offshore wind farm connectivity is reinforcing demand, as developers seek reliable export and inter-array transmission routes to integrate renewable capacity into mainland grids.
Single-core cables continue to dominate with a 69 per cent market share, although multi-core variants are poised for the fastest growth at a CAGR of 7.43 per cent.
High-voltage cables hold a 71.81 per cent share, while medium-voltage types advance at 6.31 per cent. Copper remains the leading conductor material at 71.33 per cent, yet aluminium is gaining ground with a projected CAGR of 6.30 per cent, driven by cost considerations in utility-scale deployments.
Asia Pacific commanded the largest share in 2024 at $5.12 billion, or 45.42 per cent of the global total, with China retaining its position as the dominant national market within the region.
Europe was expected to register a 5.62 per cent growth rate and reach $5.08 billion in 2025, led by Germany at $1.60 billion, the UK at $1.07 billion and France at $0.36 billion.
North America was forecast to expand at a 4.64 per cent CAGR, attaining $0.91 billion in 2025.
Both Latin America and the Middle East and Africa were each projected to reach $0.18 billion in 2025 for the GCC component of the latter.
Middle East countries with major offshore oil and gas fields, such as Saudi Arabia, the UAE, Angola, Nigeria and Egypt, are adopting power-from-shore solutions to cut emissions, while Africa, particularly South Africa, Morocco and Egypt, is exploring offshore wind farms to diversify its energy supply.
The India-Middle East-Europe Economic Corridor is also expected to incorporate undersea cables.
Nevertheless, high installation and maintenance costs together with a lack of maritime security constitute material restraints.
Environmental and regulatory standards add further challenges. In February 2024, Houthi missiles sank the Rubymar, damaging four submarine cables and affecting connectivity across 28 countries, including 17 in Africa, and disrupting service for approximately 100 million people.
The competitive landscape is led by Prysmian Group, Nexans, NKT, ABB, LS Cable & System, ZTT Group and Hengtong, among others.
Last year, LS Cable and System’s broke ground on a $777-million factory in the US, following its announcement of a $681-million HVDC subsea cable facility in Virginia in 2024.
Meanwhile, Prysmian has forecast an increase of about two-thirds in core profit by 2028.
Rising traction for interconnection projects and HVDC links in developing regions, combined with continued offshore wind farm connectivity, is expected to create substantial opportunities.
These elements will sustain the market’s role as essential infrastructure for energy security and integration across established and emerging regions alike.
