Why GF1?

Environment, Security and Sustainability

With a maximum transmission potential of 100MW, the proposed cable will help safeguard future power supply to Guernsey and increase the possibility of supplying the entire island with imported low-carbon energy, minimizing local generation and hence emissions.


Guernsey Facts and Figures 2015 published by the Guernsey Policy Council, which can be found here.



Due to a fault in the cable link between Jersey and Guernsey in 2012, Guernsey Electricity had to generate more power than usual. This graphic demonstrates that power generation is a major source of greenhouse gas emissions.

By 2050, it is estimated that we will need up to 145MW to meet the demands of the islanders. However, Guernsey Government directives are to be fossil fuel free by 2050 on the whole island

A direct link will be necessary to increase long term resilience and sustainability.

We calculate that over the life time of the direct cable link, we would save 600 kilotons of CO2 being released in the atmosphere.



The project would also facilitate the potential to provide a route to market for renewable energy to the EU market.
