Pursuant to Chapter 8² of the Energy Sector Organisation Act, the transmission system operator Elering AS issues, at the producer’s request, an electronic document called a guarantee of origin, certifying that the electricity has been produced from a renewable energy source or in a high-efficiency cogeneration mode.
The standard energy unit of a guarantee of origin is 1 megawatt-hour. One guarantee of origin is issued for each 1 MWh of electricity produced. Elering publishes information on issued guarantees of origin, the conditions and procedure for their issue, and the database used to manage them on its website.
The Green Choice product, which certifies the purchase and sale of 100% renewable energy, is based on the statutory system of guarantees of origin and is a fully transparent, precisely accounted for and verifiable system for selling electricity produced from renewable energy sources.
A Green Choice customer can be confident that the electricity purchased has been produced by a specific renewable electricity producer and that the same green electricity consumption cannot be claimed by anyone else.
