Importing low-carbon electricity
The energy we supply is predominantly imported low-carbon electricity from EDF in France. Imports provide 95% of Jersey's electricity needs. One-third of this is from renewable hydropower sources and two thirds from low-carbon nuclear power.
We import this power via three undersea supply cables know as Normandie 1, 2 and 3. The current three live links give the Channel Islands access to 245MW of low carbon imported power which we share with Guernsey as partners in the Channel Islands Electricity Grid. Jersey has access to 202MW.
Since 2011, we also buy around 5% of our supplies from the Government of Jersey-owned Energy from Waste Plant. We still generate a small amount at our La Collette Power Station, mainly due to routine maintenance operations.
Generation at La Collette, from diesel engines and gas turbines, along with gas turbines at Queen's Road remains in place primarily for strategic security of supply.
