10. IGGIGG Industry Governance Group Secretariat: RMDS Secretariat: RMDS www.rmdservice.com 10 DR1024 - Global Aggregation Currently all Independent Suppliers settled based on the aggregation of metered quantities PES – settled by difference through respective Error Supplier Unit All of the financial cost of the Residual Error Volume on the registrants of the Error Supplier Units. Global Aggregation – equal treatment in relation to the Error Supply Unit for all Supplier Units in the SEM The approved Option allocate the financial cost of the Residual Error Volume to all Supplier Units, proportionally to the amount of non-Interval meter volume as calculated for the relevant Supplier.

11. IGGIGG Industry Governance Group Secretariat: RMDS Secretariat: RMDS www.rmdservice.com 11 Global Aggregation: Option E – Enhanced Dual Factor Smear Key features in the proposal include : –Facilitates Error Supplier Units in either Jurisdiction, which allows the Modification to be implemented separately in each Jurisdiction thus providing both an All Island solution and an interim solution for RoI jurisdiction without the need for additional work. –Calculation of the Loss-Adjusted Residual Error Volume –A new annual Residual Meter Volume Interval Proportion will be determined by the Regulatory Authorities –A new Non Interval Energy Proportion for each Supplier Unit in each Trading Period, representing the proportion of Supplier Unit volume that relates to Non-Interval Metering will be created. –Addition of the Non Interval Energy Proportion to the MDP message submission (currently including meter data).

12. IGGIGG Industry Governance Group Secretariat: RMDS Secretariat: RMDS www.rmdservice.com 12 Global Aggregation: Impact on Retail Market 590, 596 597MM MRSO will provide a daily NQH factor to SEMO for each supplier unit in line with and based on the current data aggregation procedures. The proposed method for providing this factor would be to use the current 590 message that is sent to SEMO as part of each data aggregation run. For the NPED 590 MM the factor will be based on the gross NQH consumption per unit and per 30 minute interval divided by the sum of the gross NQH demand + gross QH demand per unit per 30 minute interval. For the NPEG 590 MM the factor value will always be zero. This factor would also be displayed on the 596 and 597 messages. This will result in an additional field on the 590, 596 and 597 messages in order to carry the NQH factor.

13. IGGIGG Industry Governance Group Secretariat: RMDS Secretariat: RMDS www.rmdservice.com 13 Global Aggregation: Implementation CER has sought to have this DR progressed for implementation in the Retail Market in tandem with the necessary changes in the Wholesale Market and delivered simultaneously with the next Wholesale Market Schema Release (April 2011) in order to provide an interim aggregation solution to facilitate deregulation of ESB CS tariffs.
