Blue Lab

What Blue Lab does

EDF Energy is the UK energy supply and generation subsidiary of French state-owned EDF Group (Électricité de France S.A.). It serves approximately 5 million residential and business customers across Great Britain through electricity and gas tariffs, home services (boiler installation, repair, insulation), and an array of supporting digital tools. The company is simultaneously one of the country's largest power generators, producing 31.4 TWh of zero-carbon electricity in 2024 — 17% of the UK's total zero-carbon output — through a fleet spanning five operational nuclear power stations (Hinkley Point B, Heysham 1 & 2, Hartlepool, Sizewell B), the under-construction 3,260 MW Hinkley Point C, 37 onshore wind farms, offshore wind projects (Neart na Goaithe, Codling Wind Park), and grid-scale solar installations managed by subsidiary EDF Renewables UK. Generation output is sold to the National Grid through wholesale markets and bilateral arrangements, while supply revenue is governed by Ofgem's price-cap mechanism.

EDF Energy's core technology rests on a diversified low-carbon generation base anchored by nuclear baseload, complemented by smart-meter infrastructure (over 3 million units deployed with multiple in-home display models including accessible variants), the EDF Energy Hub customer dashboard for EV tariff management, and the FreePhase time-of-use smart tariff that automates load shifting. Capital intensity is substantial: Hinkley Point C is being co-developed with China General Nuclear Power (CGN), which holds a 33.5% stake and contributes HPR1000 reactor technology for future units.

Revenue is generated through multiple streams: usage-based electricity and gas supply tariffs subject to Ofgem's price cap; fixed-rate contracts (Simply Fixed, Simply Tracker); specialized tariffs for EV owners, air source heat pump users, and solar panel owners; recurring home services contracts; and wholesale generation sales. Distribution combines self-serve digital channels (website, mobile app), call center-based customer service, listing on price comparison websites, dedicated business account managers for enterprise clients, and a national field engineering workforce for smart meter and boiler installations. The company operates from its London headquarters at 90 Whitfield Street with major operational centers in Barnwood (Gloucester) and Hinkley Point (Somerset), and was created in its current form following EDF Group's 2009 acquisition of British Energy.
