Guarantee of Origin

Guarantee of Origin

Guarantee of Origin (GoO) is the gold standard for verifying the renewable source of electricity across Europe. The GoO market spans across 30 countries under the AIB umbrella. Additionally, individual countries (e.g. Poland) can have their own national Guarantees of Origin. Each GoO is assigned a unique serial number, preventing double counting.

Each certificate contains information such as production date, location, technology, commissioning date and installed capacity of the power plant. This ensures the authenticity and reliability of renewable energy sources. Additionality can be improved by procuring special labels. These adhere to stringent criteria for green electricity production, confirming not only environmental benefits but also extra funds and social improvements in the local community.

Unbundled from the physical electricity, one guarantee of origin always represents the injection of on MWh of green electricity into the grid.
