  3. SEM R1.10.0 – Oct. 2011 • Release cut-off date was Friday, February 18th, 2011. • As at the release cut-off date there were: • No outstanding Modification Proposals approved for implementation. • No new external Change Requests received by the SEM Design Service (SDS). • One change was outstanding from the SEM R1.9.0 release (due to timeline pressures) – SEM_PC_CR172 Transfer of MIUNs from the Moyle Interconnector Trading System (MITs). Implementing this change enables: • SEMO to fulfil its obligations under the Code without the need for external contracts; • a rapid turnaround of the MIUN calculation, required under the tight timelines for Intra-Day Trading; and • the commissioning of the new Auction Management Platform (AMP) which will result in the decommissioning of MITs circa October 2011. • This change will form the scope for SEM R1.10.0 along with fixes for any outstanding defects. • There will be no SDS changes in the SEM R1.10.0 release. • Regulatory Approval for scope was received on 24th March, 2011.

  4. SEM R2.0.0 – Intra-Day Trading • Mod_18_10: Intra-Day Trading was approved for implementation at the SEM Governing Committee meeting of March 2nd. • This is a significant change, impacting many components of the Central Market Systems. Vendor effort for the delivery of Intra-Day Trading (excluding TSO changes to RCUC and hardware refresh).

  5. SEM R2.0.0 – Intra-Day Trading • The vendors have indicated that there is little scope for including additional changes within the Intra-Day Trading release, however SEMO is aware that ongoing change to the Market must continue to be considered. • With this in mind the release cut-off date for the Intra-Day Trading release is Friday August 5th, 2011. • Minor changes will be considered for inclusion in this release (Approved Modifications) • The implications of including such changes in the Intra-Day Trading release must be carefully considered in the following context: • Impact on delivery timescales for Intra-Day Trading, taking into account: • Vendor resource constraints; • Required hardware refresh; • SEMO resource constraints; and • Impact on costs. • Any change that cannot be absorbed into the Intra-Day workstream will be included within the next release where capacity is available as per the agreed process.
