ESB Networks I-SEM Programme - General Update We are continuing to work with the RAs, the I-SEM Project and the other Meter Data Providers through the I-SEM Metering Working Group We will be represented at the Market Trials Working Group which the I-SEM Programme is establishing. At this time there is NO Change to our understanding which remains that • No Changes are indicated to the Harmonised Retail Market Schema or the COBL • D+1, D+4, M+4, M+13 Settlements will continue to operate on a Working Day basis for ESBN, with no change to Frequency • Need to concurrently operate the SEM and I-SEM until Re-Settlement of the SEM completes • No Meter Data will be Price Effecting in the I-SEM and so I-SEM will not use the Price-Effecting category • I-SEM Market Trials will run Dec 2017 - May 2018 The Go-Live date for the I-SEM is 23 rd May 2018 • 2 esbnetworks.ie

ESB Networks I-SEM Programme – Price Effecting Units : Update From the Last IGG on 03.05.2017: Price Effecting Units SEM-O have identified 7 Supplier Units that are currently Non-Price Effecting, and they have started work with MRSO to move them to become Price Effecting in the SEM . This means that Eirgrid will become the MDP for them in the SEM . Eirgrid and SEM-O have confirmed the Units that will move from Eirgrid being their MDP in the SEM to MRSO becoming their MDP in the I-SEM. These are the current stats, at time of writing: • 32 Distribution Connected GUs will become NPEG from PEG • 12 SUs will become NPED from PED The current List of Distribution Connected Price Effecting Generator MPRNs is available on the RMDS website Here Please Note: this list is subject to change over time as new Units meet the criteria to become Price Effecting in the wholesale market We are continuing to work closely with Eirgrid and SEM-O on the cutover implications and the timeline for their moving in the I-SEM. Update 28.06.2017: On the 7 Supplier Units: 5 SUs have moved to become Price Effecting in the SEM, a further SU is in the process of moving to Price Effecting and the remaining SU move is pending. 3 esbnetworks.ie
