Jersey Electricity plc (JEL.L) operates as the sole vertically integrated power utility in Jersey, handling the importation, generation, transmission, distribution and supply of electricity to approximately 50,000 domestic and commercial customers across the island. The company sources around 95% of its electricity from low-carbon hydro and nuclear power imported via three undersea cables from France, supplemented by on-island solar PV generation and backup facilities at La Collette Power Station and Queens Road; its Energy Division manages core supply operations, while Energy Solutions provides advisory services on low-carbon technologies, fuel switching from gas and oil, electric vehicle charging and heat pump installations. Complementary businesses include JEBS (Jersey Electricity Building Services) offering electrical and building services to domestic and commercial clients; Jersey Energy, a design engineering consultancy with a Guernsey office providing mechanical, electrical and public health services; Jendev, developing utility software solutions; Jersey Deep Freeze, specializing in refrigeration and catering equipment design, installation and distribution; The Powerhouse, Jersey's leading electrical retailer for appliances and technology; and a property portfolio of commercial units and residential dwellings available for rent.
Founded in 1924 and headquartered at The Powerhouse in St Helier, Jersey, the company listed on the London Stock Exchange in 1964 to fund La Collette Power Station and maintains a joint venture, Channel Islands Electricity Grid, with Guernsey Electricity Limited for shared power import assets.
In recent developments, Jersey Electricity launched The Big Upgrade in 2024, a £120 million five-year infrastructure program to reinforce 10% of the low-voltage network, upgrade 100km of cabling, build 20 new substations, replace a subsea cable, add 50MW of backup generation and enhance smart metering, with the first year delivering 40 projects, 11km of new cables and upgrades serving 22 housing areas to support electrification of heating and electric vehicles in line with Jersey's carbon-neutral roadmap. The company entered a strategic talent partnership in December 2025 with Jonathan Lee Recruitment to attract engineering specialists for The Big Upgrade, focusing on substations, grid connections and renewable integration. Additional initiatives encompass the ongoing SmartSwitch smart meter rollout and completion of key substations like St Helier West in 2018, alongside Normandie 1 and 3 undersea cables commissioned in 2016 and 2014 to bolster low-carbon import capacity.
