Fuel Mix Info
Think of Fuel Mix as a "nutrition label" for electricity. The Fuel Mix provides information about the energy resources used to generate electricity that is supplied into the power grid. Just as a nutrition label provides information about calories, fats, ingredients, etc helping you know about the food you eat, the fuel mix provides information that can be useful as you shop for electricity.
Each year, by the 31st October, the various electricity suppliers are required to submit their figures for the year to 31st March to OFGEM. These individual figures allow OFGEM to prepare an average figure for the year.
For the reporting year: 1 April 2007 to 31 March 2008
Average Fuel Mix Disclosure for all Electricity Suppliers is:
The above represents the figures you should use for comparison purposes.
