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.
We believe that everyone in Guernsey should be able to use and benefit from renewable electricity. Guernsey Electricity has installed some of the largest solar arrays installed in the Channel Islands which feed more than 350kW of renewable electricity into the grid for everyone to use.
