ESB Networks I-SEM Programme - General Update We are continuing to work with the RAs, the Eirgrid I-SEM Project and the other Meter Data Providers through the I-SEM Metering Working Group We are represented at the Market Trials Working Group which Eirgrid’s I -SEM Project has established. At this time there remains 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 1 st 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 From the Last IGG on 30.08.2017: 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 • 13 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 25.10.2017: On the 7 Supplier Units: 6 SUs have moved to become Price Effecting in the SEM, and the remaining Supplier Unit move is pending. 3 esbnetworks.ie
ESB Networks I-SEM Programme – Market Trials From the Last IGG on 30.08.2017: We are represented at the Market Trials Working Group which the I-SEM Programme has established. It is too early yet to give you a detailed view from that, however as previously flagged: Unscripted Phase of the Market Trials & the RoI Retail Market For the I-SEM Market Trials Unscripted phase, our intention for RoI Suppliers and Eirgrid TSO is to make available, for those who want them, • For Suppliers; the 341,59x series of messages and 342 message for the Suppliers own generators. • For Eirgrid TSO; the 341,342, 59x series of messages Naturally this means that if you want to get these messages from the Market Trials then you will need to have a test EMMA that is available for the duration of the Unscripted Market Trials phase. You should also plan to allow for a period beforehand , possibly for a few weeks , in which your test EMMA will be connected to our dedicated I-SEM test environments. We understand that the Unscripted phase will run from Mid March 2018 thru Mid-May 2018 For planning purposes, can you let us know if you intend to avail of this facility? 4 esbnetworks.ie
ESB Networks I-SEM Programme – Market Trials • We are currently finishing out a phase of testing that has been established by Eirgrid’s I -SEM project , and which they have named CCQT (Communication Channel Qualification Testing) • This phase provided Meter Data Providers with a technical environment in which we could conduct an interface test to verify the ESB Network’s ability to interact with the Wholesale Market. • This work is still outgoing but hopefully should be completed over the next days • Included in our test suite is a move of one GU from PEG to NPEG and a move of one SU from PED to NPED. This test has been coordinated with Eirgrid. 5 esbnetworks.ie
