UK Link Programme Dashboard Report Change Overview Board 4/8/14 Executive summary • • • RAG status remains at amber Detailed Design to complete at the end of September; is challenging but achievable Priority remains to make file formats available in draft format as early as possible Functional fit remains positive at approx. 77 -80% Good attendance at UKLIEF and broad engagement by individual organisations in the Programme Future Priorities Recent Achievements • • • Supply Point Transfer End to End To Be Process published and presented at UKLIEF on 22 nd July Data Mapping overview presented to UKLIEF on 22 nd July. Functional Specifications continue to be developed as per the Detailed Design plan Significant progress has been made in the development of the Logical Design Model and Physical Design Model mapping Prepare and publish the End to End To Be Process for AQ (19 th August) Confirmation to Industry of the to-be process communication schedule and scope Continuation of Design Workshops to develop Functional Specifications Agree the approach for the early delivery of draft file formats with the industry Agree UKLIEF Stakeholder Readiness Measurement approach and begin population Industry Engagement Comms Reporting Date 2014 Q 1 2014 Q 2 2015 Q 1 2014 Q 4 2014 Q 3 2015 Q 2 2015 Q 3 2015 Q 4 To-Be Processes IE Comms. 12/5 Test Strategy 18/6 Transition Strategy 22/7 Data Mapping Presentation 01/06 Start of Market Trials, L/L Cutover Plan Q 1 2015 ~31/03 Mkt Test Transition Mods Approach & Approved Registration Process 30/09 Interface Inventory & File Formats, Transition Plan 28/08 End of Market Trials Programme Milestones Key Milestone High Level Design Complete Detailed Design Complete Xoserve UAT Complete Industry Testing Start Cutover & Implementation Baseline Date 18/04/14 29/08/14 28/05/15 01/06/15 01/10/15 Current Planned Date Complete 30/04/14 26/092014 28/05/15 01/06/15 01/10/2015 Aggregated Programme RAG Key Dependencies Risk Summary Impact Date Mitigation Industry readiness: Risk that some industry stakeholders have a low level of understanding of Nexus requirements due to lack of attendance at industry forums 01/06/15 UKLIEF established need for Stakeholder Readiness Framework to monitor industry readiness. Scope: Raising of new mods which impact the baselined requirements will impact Oct 2015 delivery. On-going UKLP baselined scope now communicated Change control process now in place to manage scope Q 4 2014 Xoserve to consider mitigating actions i. e. dummy test files in advance while preparing Market Trials Approach. Market Testing: Risk that Market Trials is insufficient in length, too late within the programme, and participants may not be ready in time to take part. Dependency Date Required Impact if missed Industry participants to cleanse data by December 2014 to feed into UAT 31/12/14 UAT timelines may increase due to increased number of data issues, leading to an overall delay to the implementation. Industry agreement of process change to adopt SAP ‘Out of the Box’ May 14 September 14 Delays in confirmed changes to industry stakeholder systems with follow on impacts on market test and implementation readiness Industry agreement of file formats. Oct 14 Delay in approving file formats may lead to design rework which will impact programme build and testing timescales. Status

Baseline Date 30/06/14 15/08/14 31/07/15 01/10/15 Aggregated Programme RAG Recent Achievements: Priorities For Next Month: • • Application Design phase is progressing to plan Greater understanding is developing of the dependencies between UKLP and EU Reform and development of options to mitigate the delivery risks. • • Start Application Build Upgrade test environments to accommodate EU Changes • • Adjacent Transmission System Operators may use data exchange tools that are not compatible with Gemini’s data exchange tool High risk of change due to unapproved EU Codes and mods • Baselining and approval of modifications is required. • • DCC Day 1 went live successfully on 28 th June. Delta files are being received on a daily basis • • • Commence Build phase for DCC Gateway project Provide SEC 4 response Complete RDP consultation on baselined SIT Approach document for the DCC • • • Uncertainty over revised DCC go-live Late delays to UKLP or DCC implementation would impact DCC Gateway cutover There is a risk of a large number of record rejections if Supplier IDs are not correctly set up on i. GT systems by DCC Day 1 • DCC Gateway deployment approach is dependent upon the sequencing of DCC and UKLP go live dates. • • Build and Unit Test activities have been completed System testing has commenced and progressing to plan • • • Continue with System Testing Continue with UAT preparation activities Issue External communications on the handling of transition and cutover scenarios • Increased efforts in testing as Faster Switching functionality is to be delivered in Legacy and new world UKL. • None – relevant Mod now approved for implementation Risks: 30/06/14 Complete Current Planned Date 20/08/14 15/07/15 01/10/15* Dependencies: *Cutover to be planned alongside UKLP Smart Portfolio – DCC Day 1 & DCC Gateway Key Milestone DCC Day 1 Impl.
