The Spanish regulatory authority and official GO issuing body, CNMC, has become an AIB member and is now adherent to the EECS Standard. The German competent body for GOs, UBA, has been adherent to the EECS Standard since 2014 and has recently decided to become an AIB member.
The Spanish GOs now being EECS standardized could result in a significant change to the market for GOs in Europe. This change will be implemented for the 2016 electricity production year.
For more information on the development of the Spanish GO system refer to the press release from the AIB here.
