Essential maintenance to GJ1 Jersey – Guernsey electricity cable

May 17th, 2017 by Guernsey Electricity Ltd.

Guernsey Electricity switched off the cable importing electricity from France in early May 2017 to undertake essential maintenance work to the Channel Islands Electricity Grid.

The planned maintenance should take about two weeks to complete.

It will include work in the Barkers Quarry substation, as well as complementary work on the grid in Jersey and France.

After two successful years of operation following a pre-emptive repair in 2015, the submarine cable GJ1 will be inspected and reburied.

The CS Recorder, a ship owned by GMSL, will rebury the section of cable subject to weather conditions.

Alan Bates, Chief Executive of Guernsey Electricity, said “‘we are undertaking maintenance of the Channel Islands Electricity Grid system to ensure that our infrastructure continues to provide Guernsey with a secure and stable power supply.

This work has been carefully planned for the summer months when electricity demand is at its lowest level.

We have ensured that Guernsey Electricity Ltd’s on-island electricity generators are ready to meet the demand,” he said.

“The cable GJ1, which imports low carbon energy from France via Jersey, normally provides up to 90% of Guernsey’s electricity.”

Guernsey Electricity Ltd has invested nearly £30 million in on-island generation infrastructure to meet the island’s electricity demand during electric cable maintenance.
