title: Channel Islands Electricity Grid
text: # Channel Islands Electricity Grid
  
  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.
  
  Long term agreements with Électricité de France (EdF) ensure the imported electricity is low carbon. Ninety percent of Guernsey’s electricity is imported from the grid.
  
  Co-operating through the CIEG means the islands can work together towards improving the reliability of the grid system.
