All our residential fixed energy tariffs are backed by 100% zero carbon nuclear electricity, with the exception of our EV tariff which is backed with renewables. See our product table for more information.
UK Fuel Mix disclosure information, published by Government Department BEIS, recognises electricity from wind, solar and nuclear fuel produces zero carbon dioxide emissions at the point of generation.
The zero-carbon electricity purchased is supplied to the National Grid. Customers receive electricity via the National Grid, not directly from zero-carbon generators.
The below table summarises zero-carbon generation by company demonstrating EDF generating 32.4%. The data supporting the table below and the % values is sourced from a mixture of industry settlement data and the UK government renewable obligation database.
