Submarine Power Cable Market Trends

Market Driver - Growing Demand for Renewable Energy, Particularly Offshore Wind Farms

As countries around the world aim to reduce carbon emissions and transition towards cleaner sources of energy generation, renewable energy is playing an increasingly important role. One renewable energy source that is seeing significant gains is offshore wind power.

Submarine power cables are essential infrastructure that are used to transfer the vast amounts of renewable electricity generated by offshore wind turbines from their offshore locations to the mainland power networks. Major offshore wind power markets like those in North West Europe and East Asia have been early adopters of the technology. Countries like the UK, Germany, Belgium, Netherlands, Denmark, China, Japan, and South Korea have laid hundreds of kilometers of submarine cables to strengthen their offshore wind power connections.

New markets are also emerging, especially across parts of Southeast Asia, Middle East, and the Americas. As the global momentum behind renewable energy and offshore wind power continues to gather pace, growth in the submarine power cables market is expected to remain robust to support the ballooning offshore networks.

Market Driver - Increasing Inter-country and Island Power Connections to Enhance Grid Reliability

Building power interconnections between countries and island territories have been an important strategy adopted by many regions to improve energy security and create resilient electricity grids. However, laying overhead transmission lines across long stretches of sea can be technically challenging and expensive. That is where underground/undersea power cables have emerged as a preferable solution. Submarine power cables provide a reliable and cost-effective means to connect distant power grids that are separated by large bodies of water. They allow smooth power transfers while creating redundant transmission capacity between networks.

The need to transport high volumes of renewable power over long distances will also support growth. Overall, the promise of leveraging dormant offshore wind and hydro potential through cross-border undersea interconnectivity makes submarine power cables a strategic technology for building stronger and sustainable energy systems worldwide. Their deployment in new terrestrial and offshore interconnector projects will likely gather momentum.

Market Challenge - High Installation and Maintenance Costs Associated with Submarine Cables

One of the key challenges faced by the submarine power cable market is the high installation and maintenance costs associated with underwater cables. Laying cables on the seabed requires specialized installation vessels that can deploy cables at significant depths. These vessels are equipped with complex machinery and equipment to handle cable lengths of over hundreds of kilometers.

Power utilities also need to continuously invest in maintenance activities such as repair and replacement of damaged cables. Adverse weather conditions and human activities continue to pose risks to underwater infrastructure. The high upfront installation costs and long-term maintenance liabilities pose financial constraints for utilities especially in emerging economies and island nations dependent on submarine interconnectors.

Market Opportunity - Technological Advancements Leading to More Efficient and Durable Cables

One of the key opportunities available for the submarine power cable market is the technological advancements leading to development of more efficient and durable cables. Continuous research and development efforts are underway to design cables that can withstand greater mechanical stresses, operate at higher power ratings and remain functional over longer durations.

Materials research and refinement of insulation technologies have enhanced cable performance metrics. Advances such as mass impregnated papers and cross-linked polyethylene insulation have extended operational lives. Dry-mate cable connectors and repair clamps have streamlined maintenance activities.

Adoption of durable, high-capacity cables can help lower per unit costs of transmission over longer distances. When coupled with demand for interconnectivity of offshore renewable assets, technological innovations are expected to support growth of the submarine power cable market.
