Why promote carbon-free energy?
The widespread use of renewable energy is one of the cornerstones of the energy transition, which is essential to limiting climate change. Since the deregulation of the electricity market, suppliers have been competing to offer so-called “green” plans.
But what does this label really mean, given that before it reaches your business, a “green” electron generated from a renewable or carbon-free source loses its “color” by mixing with all the others? The system of guarantees of origin (GO) provides an initial level of proof.
But then, that supplier must procure electricity to satisfy its customers, and it doesn’t necessarily buy it from the renewable producers in question! Nor at the same time! To address this shortcoming, ADEME created the VertVolt label. It is based on a set of criteria requiring, among other things, the purchase of green electricity and the associated GO from the same producer—and a French one at that.
Two levels of commitment have been defined: “committed” (the supplier structures its offering by contracting with clearly identified producers, including nuclear producers) and “highly committed” (an offering composed of more than 25% from producers whose facilities built after 2015 did not receive public subsidies, or who have placed their company under shared governance).
And an optional designation, “nuclear-free”: here, the supplier waives its right to access the ARENH, a mechanism that grants it access, at a regulated price, to electricity produced by existing nuclear power plants.
