Join over 150 industry peers and more than 70 senior practitioners and technical experts on 18-19 November 2025 in London, United Kingdom (plus hybrid attendance option) at the Marriott Hotel Regents Park. This is the 5th Annual Submarine Power Cable and Interconnection Forum — a crucial gathering for anyone invested in the future of undersea cables, HVDC Transmission, and cross-border energy infrastructure.

Why This Forum Matters

In a time when energy demand is surging and clean power sources like offshore wind, tidal, and wave are being tapped at scale, robust electricity interconnection becomes essential. Electricity interconnector systems help supply, distribute, and balance clean power across nations and regions. Meanwhile, HVDC Transmission technology serves as the backbone for efficient, long-distance undersea energy transfer, minimising losses and enabling reliable connectivity even under challenging marine conditions.

The Forum will focus on how submarine power cables and interconnection infrastructure must evolve to support this transition. It is not just about engineering and technology but about ensuring affordable, stable electricity access, enhancing resilience, and reducing carbon footprints globally.

What to Expect

Over the course of two days, you will engage with:

• Case studies and interactive sessions from successful submarine cable & interconnection projects around the world, with a strong focus on HVDC Transmission implementations.
  

• Panel discussions on design, installation, maintenance, fault detection, route surveying, cable assets health, and life extension—all in the context of interconnection and undersea cables.
  

• Technical deep dives into the latest in electricity interconnector technology, policy, regulation, and investment frameworks.
  

• Workshops and experience sharing on how to reduce costs and risks in submarine cable deployment and maintenance, particularly for electricity interconnection across borders.
  

Who Will Be There

Attendees include senior decision-makers, project developers, technical engineers, submarine cable manufacturers, regulators, TSO (Transmission System Operators), financiers, offshore wind developers, and environmental and marine experts. All are unified by a common goal: advancing global energy infrastructure through stronger electricity interconnection and leveraging HVDC Transmission as a central tool.

Key Themes & Topics

• Innovative HVDC Transmission methods for subsea and hybrid systems
  

• Best practices in cable protection, installation, monitoring, and repair

This forum is ideal for:

• Engineers, technical leads, and project managers in submarine cable systems and HVDC Transmission
  

• Developers, investors, and policy makers involved in planning or regulating electricity interconnection projects
  

• Utility companies, TSOs, and offshore wind players who use or will use electricity interconnector infrastructure
  

• Environmental and marine specialists are concerned with the ecological impact of undersea cables
  

• Suppliers, manufacturers, installation contractors, and maintenance service providers

What You Will Gain

By attending, you will:

• Acquire practical insights into deploying HVDC Transmission solutions undersea
  

• Understand cost reduction, risk mitigation, and asset-life extension techniques for submarine power cable systems
  

• Be part of shaping the conversation around regulation, financing, and technical standards for electricity interconnection
  

• Connect with peers and experts who are driving forward the deployment of electricity interconnector infrastructure
  
  

Leave with knowledge to better plan, operate, maintain, and integrate interconnectors in your projects
