Guarantees of origin

The administrator of the Estonian Guarantees of Origin system is the joint system operator, who issues guarantees of origin in Estonia and manages the electronic database of guarantees of origin (hereinafter, the “Register”).

All activities related to the issuance, transfer, and cancellation of biomethane Guarantees of Origin are carried out within the register.

The standard terms and conditions for the use of biomethane and hydrogen Guarantees of Origin establish the rules and procedures for using the register, under which market participants can perform operations with Guarantees of Origin. The standard terms are established pursuant to § 32¹⁰ subsection 12 of the Energy Sector Organisation Act.

The quantity of biomethane for which a Guarantee of Origin is issued is calculated based on the higher heating value (HHV).

The quantity of biomethane for which a Guarantee of Origin is issued, as well as the quantity of gas for which the origin is certified using a biomethane Guarantee of Origin, is determined by a remote metering device.

A Guarantee of Origin can be transferred electronically only within the register, between different accounts.

Starting from the 2025 production year, Elering, as the representative of the Estonian domain, will issue biomethane Guarantees of Origin compliant with the standardized European rules for Guarantees of Origin — the European Energy Certificate System (EECS) — as a member of the Association of Issuing Bodies (AIB) gas scheme.
