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 mainland Europe and the Channel Islands.
The grid physically comprises a network of high voltage (90 kV, 3-phase, 50 Hz) submarine and underground cables linking the French electricity grid to the electricity systems on the islands of Jersey and Guernsey. The grid enables electricity generated from renewable sources in France to be transmitted to Jersey and Guernsey.
Development
The CIEG is continuing to develop the undersea cable network with additional subsea cables between the islands and France being devised to 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.

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