The various industries including commercial operations and telecom services and energy production and power distribution, are driving infrastructure expansion and upgrades, which will create new market opportunities.
By End-use
The offshore wind power generation segment would have the highest share of the market in 2025. The market expands because of two main factors which include greater investment in offshore wind power generation and increased use of submarine power cables for long-distance power transmission from these facilities. The Global Wind Energy Council announced that worldwide offshore wind capacity reached 10.8 GW in June 2024 after the installation of new capacity during 2023 which brought the global total to 75.2 GW and showed a 24 percent increase from the previous year.
The inter-country & island connection segment is growing at a rapid rate over the projected period. International linkages together with island connections create market demand because countries need to build improved communication systems while they establish dependable power distribution networks. Submarine cables provide remote islands together with faraway countries their internet and electricity connections which support their economic development and digital equality goals.
