1. What is I-SEM?

The wholesale market on the island is due to change considerably to take account of the requirements of the European Network Codes and the Target Model, including a change to four market timeframes. This will be the new I-SEM (Integrated – Single Electricity Market) market design Key elements of which include:

  • Active participation by supplier companies – submitting bids to purchase energy in the day-ahead and intraday markets.
  • Suppliers and generators paying / being paid based on prices and quantities determined through ex-ante (forward, day-ahead and intraday) trading.
  • Cross-zonal power flows determined based on energy market trades and power flowing from the cheaper to the more expensive bidding zone.

For more information, please visit the I-SEM Homepage.

3. How does I-SEM communicate to Market Participants?

The I-SEM Project is working with the RAs and Participants to ensure everyone is ready in time for Go-Live. The I-SEM Project has established the following 4 working groups to liaise with participants to keep participants informed and to address any issues raised:

  • Market Rules Working Group (RWG) - An established group of participants, ISEM project and Regulatory staff working to finalise the rules for the new market.
  • Project Managers Group (PMG) - This group mainly works through the Project Plan/Key Milestones, Schedules and Readiness.
  • Technical Liaison Group (TLG) - Technical Design, System Communications and Readiness.
  • Business Liaison Group (BLG) - Business, Functional & Process Readiness. These differ per subject matter, there have been two to date one on AOLR (Aggregator Of Last Resort) and one on NEMO (Nominated Electricity Market Operator).

12. Where can I find more information on I-SEM Project Governance?

Given the scope of the Detailed Design and Implementation phase of the I-SEM project, the RAs and TSOs have put in place a dedicated governance structure and set of working arrangements. A number of symposiums will be held until project conclusion and the intention of these is to combine the knowledge and expertise of both the RAs and TSOs/MOs.

There are a number of groups that form part of the Governance Framework. These groups are:

  • I-SEM Steering Group
  • Joint Project Board (JPB)
  • Joint Project Manager Liaison
  • Workstream Groups

For more information on I-SEM Project Governance, please refer to the SEM Agreed Approach document.

13. Where can I find more information on the I-SEM Change Control Process?

The SEM Agreed Approach document requires that a Change Control process must be approved by the I-SEM Steering Group. This process should be in line with recognised industry standards.

To comply with this overall requirement for I-SEM Programme delivery, a standard process is needed to manage all proposed changes to the baselined programme time, cost or quality, which impact on two or more parties within the overall programme.

In this context:

  • Baselined time = unrecoverable slippage to any milestone on the Level 2 programme plan (and by inference, also Level 1 milestones);
  • Baselined cost = any proposed variance from the agreed financial envelop for the I-SEM Programme; and
  • Baselined quality = the scope and functionality of the I-SEM, as set out in the design documentation and specifications to be baselined Dec 2015 onwards, on which two or more parties depend.

A party is any one of:

  • CER and UR, acting jointly;
  • TSO – in its delivery role;
  • The Interconnector Owners (ICOs) – in their delivery roles; or
  • Any other stakeholder involved in the I-SEM Programme e.g. TSO in any other role, generators, suppliers.

The Change Control process should not be used for non-baselined documentation or management products such as minutes of meetings, or interim products such as working papers, registers or action lists; these changes should be managed ‘internally’ by the various workstream managers and PMO.

The Regulatory Authorities have overall responsibility for defining and maintaining the Change Control procedure, and changes to it will be managed through the RA I-SEM Project Office.

For detailed information on this process, please see the Programme Change Control Procedure document.

14. The Industry Guide to the I-SEM states that "A non-dispatchable and non-controllable unit cannot participate in the balancing market". Is this correct?

The guide is technically correct because in this context “participate in the balancing market” refers to actively submitting incremental and decremental bids to the TSOs.

Note the definition of Balancing Market provided in the Trading & Settlement Code states that this “means the arrangements under this Code that provide for the market-based management of System Operator actions and processes to balance continuously generation and demand and to maintain the stable and secure operation of the electricity transmission systems on the island of Ireland”.

This naturally precludes non-dispatchable and non-controllable units as they are not subject to System Operator dispatch. This does not preclude non-dispatchable and non-controllable units from participation under the Trading & Settlement Code in relation to imbalance settlement and other requirements. We recognise that this language may lead to some confusion where the term balancing market has sometimes been used as a synonym for the balancing and imbalance settlement arrangements. This text could also read “A non-dispatchable and non-controllable unit cannot submit bids and offers to the TSO in the balancing market”.
