Guarantees of Origin (GOs) are electronic certificates issued for energy from renewable sources. GOs are issued to eligible Generators, for every 1 MWh of energy produced.
The sole purpose of GOs is for use in Fuel Mix Disclosure. For information on Fuel Mix Disclosure please click here.
As per Statutory Instrument (S.I.) no.147 of 2011 (replaced by S.I. no. 483 of 2014), SEMO is named as the issuing body for GOs in Ireland. This scheme is for in-market (SEM) generators, out-of-market generators, and suppliers in Ireland.
SEMO became a member of the Association of Issuing Bodies (AIB) on the 19th of May 2015. The Domain Protocol outlines how SEMO's operational processes align to the European Energy Certificate System (EECS) rules.
The EU Directive (2009/28/EC) regarding GOs was transposed into law in Ireland, on the 28th of March 2011, by Statutory Instrument (S.I.) 147 of 2011 (replaced byS.I. no. 483 of 2014). This S.I. named SEMO as the issuing body and the CER were required to set up a Supervisory Framework for GOs.
This Supervisory Framework was outlined in the Decision Paper CER/11/824 “Supervisory Framework for Administration of Guarantees of Origin”.
