The CIEG (Ltd)

The CIEG (The Channel Islands Electricity Grid) 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 (Ltd) is continuing to develop the undersea cable network with additional cables to Guernsey and Jersey from France.

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 Electricité de France ensure the imported electricity is low carbon. 

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