The fuel mix for the year 1 April 2016 to 31 March 2017 is shown below.

The fuel mix values are the GB Residual Fuel Mix, which means the supplier does not have generator declarations for the sources of the electricity they are supplying. Utilita's published figures were initial values for Residual Fuel Mix which were updated on 25 August 2017, so we have used the updated figures.
