Where our electricity comes from
Our subsea cable is Guernsey's primary source of electricity and has delivered a 37.5% decrease in Guernsey's emissions from 1990 levels. But we still have some way to go before Guernsey is net zero.
-
94%
of Guernsey's electricity is imported using a sub-sea cable to Europe via Jersey.
-
60MW
This cable can provide 60 Megawatts of electricity which covers all of Guernsey's electricity in the summer but a top-up is required in colder months.
-
92MW
is our highest ever peak demand during storm Darcy in 2021. We need to be able to provide this at all times.
-
37.5%
decrease in Guernsey's emissions from 1990 levels since the cable was installed in 2000.
-
100%
of our electricity can be generated from our power station. This means currently our power station gives our background security of supply as it can provide all of the island's electricity if needed.
-
300kW
of local community scale solar PV has been installed by us since 2019
Something about this
Our imported electricity, previously a mix of nuclear and hydro, is now sourced from 100% renewable sources such as solar, wind and hydroelectricity.
‘Guarantee of Origin’ certificates (GoO’s) are the current market mechanism for driving investment in renewables. We are using our market power to drive investment to the right places. By increasing the demand for renewable and sustainable electricity, we reduce the investment into fossil fuels. The more communities that make this same choice, creating more demand for energy from sustainable energy sources, the more generators will invest in these technologies.
Guernsey currently uses between 30MW (megawatts) and 90MW of electricity throughout each day. We expect this to increase in the future so we need to ensure that we can always keep the lights and WiFi on, and our homes warm.

8 June 2021What happens to old electric car batteries?
Electric cars in Guernsey are powered by over 93% renewable energy. And, they produce no pollution meaning cleaner, healthier air for us all to breathe. But there are still a lot of questions about the life of electric vehicle batteries and what happens when they’re no longer used in an electric vehicle. -
