The Channel Islands Electricity Grid (CIEG) is the joint company set up in 1998 between Guernsey Electricity and Jersey Electricity to operate and manage the submarine cables between Europe and the Channel Islands.

The CIEG is continuing to develop the undersea cable network with additional connections between the islands and France currently being devised. These subsea cables will give both Guernsey and Jersey greater security and better affordability, as they will give the islands the opportunity to increase the amount of imported energy.

Long term agreements with Électricité de France (EdF) ensure the imported electricity is low carbon. [1]

Co-operating through the CIEG, means the islands can work together towards improving the reliability of the grid system.
