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.{{Cite web |date=2017 |title=Implementation of a system integrity protection scheme in the Channel Islands |url=https://www.researchgate.net/publication/321202546 |access-date=}} 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{{cn|date=May 2021}} 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.{{cite web |url=http://www.sustainableguernsey.info/blog/2013/05/channel-islands-electricity-grid-strengthened-with-new-agreement/ |title= Channel Island grid strengthened |publisher=Sustainable Guernsey |date=29 May 2013}} Ninety percent of Guernsey’s electricity is imported from the grid.{{Cite web |title=Channel Islands Electricity Grid |url=https://library.e.abb.com/public/6e3b8cadb22a8e4fc1257b0c005527b7/815_CIEG_Referenz.pdf}}

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