The global submarine power cable market is set for sustained expansion over the next decade, driven by the rapid deployment of offshore renewable energy projects, rising cross-border electricity transmission, and growing investments in resilient power infrastructure. According to a new analysis by Fact.MR, the market is projected to grow from USD 7.2 billion in 2025 to approximately USD 12.8 billion by 2035, registering an absolute increase of USD 5.6 billion over the forecast period.
This represents a total growth of 77.8%, with the market expected to expand at a compound annual growth rate (CAGR) of 5.9% from 2025 to 2035. Increasing focus on energy security, decarbonization, and offshore electrification is accelerating global adoption of submarine power cable systems.
Strategic Market Drivers
Offshore Wind Energy Expansion Drives Strong Demand
The accelerating global transition toward renewable energy is significantly boosting demand for submarine power cables. Offshore wind farms require high-capacity, durable subsea cables to transmit electricity from offshore installations to onshore grids.
Large-scale offshore wind projects across Europe, East Asia, and North America are acting as primary growth engines for submarine cable installations.
Cross-Border Power Interconnection Projects Gain Momentum
Governments and utilities are increasingly investing in cross-border and intercontinental power transmission to enhance grid stability and energy security. Submarine power cables enable long-distance electricity exchange between countries and regions, supporting load balancing and renewable energy integration.
Interconnector projects linking mainland grids to islands and neighboring countries are expanding rapidly worldwide.
