Multi-Purpose Interconnectors

Why a new generation of interconnector holds the key.

Interconnectors already provide a way to share electricity between countries safely and reliably. But what if they could do much more than that? What if interconnectors could become an offshore connection hub for green energy?

Instead of individual wind farms connecting one by one to the shore, Multi-purpose interconnectors would allow clusters of offshore wind farms to connect all in one go, plugging into the energy systems of neighbouring countries.


Tomorrow’s solution: Offshore wind and interconnectors in harmony

At present, offshore wind and interconnectors operate alongside each other. In the future, Multi-Purpose Interconnectors could enable offshore wind and interconnection to work together as a combined asset.

Key benefits of Multi-Purpose Interconnectors

  • Support UK efforts to meet 2030 and 2050 climate targets
  • Reduce impact on coastal communities with fewer individual connections and less construction needed
  • Enable a reliable flow of electricity that can be turned up or down when needed
  • Generate a greater proportion of electricity from the North Sea via offshore wind
  • Provide significant cost reductions by using shared assets and clusters of connections

Projects combining interconnections and offshore wind will help reduce the amount of electricity works onshore, meaning that any impact on coastal communities is kept to a minimum. As offshore wind developers are determined to work closely with local communities and to be good neighbours, this is an important consideration for our sector.
