What are Interconnector risks?

An interconnector for a subsea cable refers to the infrastructure that connects two or more electrical grids located in different countries or regions through an underwater cable system. These interconnectors enable the transmission of electricity across borders, allowing for the sharing of power resources, increased energy security, and integration of renewable energy sources.

While interconnectors offer various benefits, they also come with certain risks, including:

  1. Technical failures: Subsea cables are exposed to a range of potential technical failures, such as cable faults, insulation breakdown, or equipment malfunctions. These failures can lead to power outages or disruptions in the flow of electricity.
  2. Damage from external sources: Subsea cables can be vulnerable to damage caused by external factors, including natural disasters like earthquakes, storms, or tsunamis. Ship anchors, fishing activities, or geological activities can also pose risks to the cables.
  3. Cybersecurity threats: Interconnectors rely on complex digital systems for efficient operation and control. These systems can be susceptible to cyberattacks, which could potentially disrupt the flow of electricity or compromise the security of the connected grids.
  4. Financial risks: Interconnector projects are often significant investments involving substantial capital expenditure. There are financial risks associated with cost overruns, delays, or changes in regulatory frameworks that can impact the economic viability of the project.
  5. Regulatory and political risks: Interconnectors involve cross-border cooperation and coordination between different countries or regions. Changes in regulatory frameworks, political instability, or disputes between participating entities can introduce uncertainties and affect the functioning of the interconnector.
  6. Environmental impact: The installation and maintenance of subsea cables may have environmental implications, particularly during the construction phase. Activities such as seabed disturbance, noise generation, or disruption to marine ecosystems can occur, potentially impacting marine life and habitats.

It’s worth noting that these risks are not unique to interconnectors but are common to various infrastructure projects. However, through proper planning, design, monitoring, and risk management strategies, many of these risks can be mitigated to ensure the reliable and safe operation of interconnectors.
