In France, renewable energies accounted for 20% of total electricity production in 2018. To meet the climate challenge, this share must reach 40% in 2030 through the development of production capacities. In this period of energy transition, Hermès sought the best solution that favoured green electricity for its own consumption in France, supporting the Paris agreement of December 2015 without delay. This led the house to choose EDF's 100% renewable energy option, which was the only nationwide offer for industry at the time.
The contract between Hermès and the long-standing electricity provider promotes renewable energies in France. It ensures that a quantity of electricity equivalent to that consumed by the group's stores, workshops, offices and other facilities in France is injected into the grid in the form of so-called "green" electricity, and that it comes from French sources. EDF either produces kilowatt-hours directly using its own renewable energy capacity (mainly hydroelectric power plants), or purchases them from competing producers on the French Powernext electricity exchange.
In the latter case, the idea is to apply a form of compensation that is not unlike the mechanism used to offset CO2 emissions.
The guarantee of origin (GO) for a source of supply is exercised through certificates of origin sent by EDF to Powernext, which thus acts as a certification body. The number of this GO allows Hermès to identify the production site that issued it, most often a hydroelectric power plant. Hydraulic power remains the leading source of renewable energy in France.
