Using the latest available data would put EDF Energy's % of low carbon generation at 35%, with Other at 39%. The 39% of Other can itself be broken down into many different owners, the top ten by share of the Other owners and their percentage share of that 39% is below:
DONG Energy RB (UK) Ltd
5.90%
Vattenfall Wind Power Ltd
3.36%
Morecambe Wind Limited
2.91%
Fred Olsen Renewables Ltd
2.59%
Walney (UK) Offshore Windfarms Ltd
2.59%
Clyde Windfarm (Scotland) Limited
2.44%
Galloper Wind Farm Limited
2.42%
Octopus Investments Limited
2.37%
Foresight Group LLP
1.97%
Falck Renewables Ltd
1.86%
DONG Energy alone accounted for 2.3% of all low-carbon generation in 2018 (38% x 5.9%), with Vattenfall a further 1.3%, and Fred Olsen 1.0%. Removing DONG, Vattenfall and Fred Olsen would leave Other at 34.4%, which itself is still made up of many smaller, independent generators with split ownership. It is, therefore, the case that EDF was the single largest generator of low-carbon electricity in 2018.
The low-carbon electricity that we buy for Residential, Blue or Renewable tariffs and products is supplied into the National Grid. Customers receive that electricity through the National Grid, not directly from low-carbon generators.
