Risks

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 communicatedChange control process now in place to manage scope

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.

Q4 2014

Xoserve to consider mitigating actions i.e. dummy test files in advance while preparing Market Trials Approach.

Recent Achievements:

• DCC Day 1 went live successfully on 28th June.• Delta files are being received on a daily basis

Priorities For Next Month:

• Commence Build phase for DCC Gateway project• Provide SEC 4 response• Complete RDP consultation on baselined SIT Approach document for the DCC

Risks:

• 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 iGT systems by DCC Day 1

Dependencies:• DCC Gateway deployment approach is dependent upon the sequencing of DCC and

UKLP go live dates.

Recent Achievements:

• 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.

Priorities For Next Month:

• Start Application Build• Upgrade test environments to accommodate EU Changes

Risks:• 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

Dependencies: • Baselining and approval of modifications is required.
