What is a guarantee of origin?

A guarantee of origin is an electronic document that proves to the final customer that a quantified amount of electricity originates from a specific renewable energy, or is produced by cogeneration.

Guarantees of origin track green energy from the producer to the final consumer, ensuring a full transparence for these consumers.
