Residual Mix Figures

The residual mix is nothing more than a grid emission factor. The difference between a grid emission factor and the residual mix is that the residual mix incorporates the allocation (use) of renewable energy by those that have purchased electricity tracking certificates like Guarantees of Origins (GOs). When determining a residual mix most often one excludes cancellation of electricity attributes (purchased via a GO certificate in Europe) from the grid emission average. In this way the problem with double counting the 0-carbon attributes of green electricity is resolved. 

Suppliers are required to disclose their electricity fuel-mix according to European law, 2009/72/EC. To do this is quite easy if the supplier cancels GOs. This way they know exactly how much, of what electricity source was given to their consumers.

Example: If aNorwegian supplier sold 100 MWh of electricity and canceled 100 MWh of hydroelectricity they know where all of their electricity comes from and from which specific hydroelectric plants their electricity was supplied. If the same electricity supply company delivered 100 MWh but only canceled 50MWh of hydroelectric GOs then the supplier should report 50% hydroelecric electricity and 50% residual mix (based on the below figures)

The use of a residual mix is not mandatory in some European countries but its use is becoming the best practice in all member states. 

The residual mix figures for 2014 are placed here below.
