Why GeM?

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, minimising local generation and hence emissions.

This graph shows the high percentage of greenhouse gas emissions from power generation in 2012. This was due to a fault in the cable link to France, via Jersey, which resulted in the need to generate electricity on-Island for 6 months.


Environment, Security and Sustainability

This graphic demonstrates that power generation is a major source of greenhouse gas emissions.

A new record for electricity demand of 89 MW was reached on 1st March 2018, and it is expected to reach 100 MW by 2025.

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.
