French national mix
The following energy mixes are computed using the production data of RTE and the Guarantee of Origin mechanism.
The production mix represents the share of each source of energy in the country's power production.
The consumption mix represents the share of each source of energy in the country's actual power consumption. The French consumption mix is calculated from the import and export-adjusted national power production, as monitored by the Guarantee of Origin mechanism.
The residual mix represents the share of all sources of energy in the electricity that is not traced by Guarantees of Origin.
Use of the residual mix by suppliers
The residual mix enables suppliers to measure the share of all sources in the electricity they receive when it is not accompanied by a Guarantee of Origin. This is the case when it is purchased via an organised market for instance. This share of renewable cannot be used for green electricity provided to consumers subscribing to green offers.
How to calculate the mix?
1. Determine the volume to be disclosed
After the end of Year N, determine total electricity sales of year N as well as the volume and type of each electricity product sold in year N.
2. Cancel your Guarantees of Origin
You need to cancel your GOs at the latest before 31st March of Year N+1. We advise you to cancel your GOs progressively throughout the year. For year N, cancellations can be made between 1st April N and 31st March N+1.
You are obliged to cancel GOs to cover at least the amount of green electricity you sold during the year. Voluntarily, you can as well cancel more GOs, in order to improve your total supplier mix.
3. Determine your residual electricity
You have already disclosed the green offer part of your mix.
If you are supplying 100% green electricity to all your customers, then you have done everything already.
If you only offer non-specific energy offers (you have not cancelled any GOs), then you can simply apply the residual mix to your total supply volume of energy.
If you have cancelled less GOs than your total supply volume (for specific green offers or just to improve your supply mix), then you may deduce the volume of used GOs from your total supply volume and then apply the residual mix to the remaining volume.
