The guarantee of origin is the only proof of the origin of the energy consumed.

A guarantee of origin issued in Estonia or a contracting State of the European Economic Area and deleted from the Estonian register of guarantees of origin is used to prove the origin of the energy consumed. A guarantee of origin is valid for 18 months following the production of fuel or energy. This means that the guarantee of origin can be deleted to prove the origin of the energy consumed within 18 months after the end of the production period. A guarantee of origin can be transferred to another account within 12 months after the end of the production period of an energy unit. Guarantees of origin can be obtained together with energy, or separately.

The standard energy unit of a guarantee of origin is 1 MWh and one guarantee of origin is issued for each standard energy unit produced.
