Assurance Activities• Conducted project closure for June 2010 MDU
– Lessons learned review carried out with RMDS
– Obtained Market Participant feedback for June 2010 MDU
• Two new Suppliers currently undergoing market entry
• Preparation for MCR 0161 & Defect 8455 IPTs
• Initial preparation for the November 2010 MDU assurance activities
MCR 0161 & Defect 8455 Update
MCR 0161 & Defect 8455 Update
• MCR 0161 – Change from MIC to connection voltage as threshold for connection agreement return
• New threshold to be medium voltage or higher
• IPTs are scheduled for September 6th, 2010.
• Go Live is planned for 18th September, 2010.
• IPTs will be run by ESB CS
MCR 0161 & Defect 8455 Update
• Defect 8455 to be included with MCR 0161
• Defect fix will resolve the bug in the following instances:
– Where a reduction in the MIC has been requested
• Existing CA request (in process) not recognised
• Incorrectly triggers 102P
• Incorrectly triggers duplicate CA
June 2010 Market Participant Feedback
Market Participant Feedback from June 2010 Market Design Update
• The approach was to contact all market participants for feedback
• The information collated was categorised by:
– Preparation
– Documentation (RMDS and Gemserv)
– IPT
– Cut-over
– Communication
– Areas for future improvement
Preparation• Expected timescales on Project roadmap were met.
• Relevant documentation was provided in a timely manner to set the expectations required for each market participant.
• The tiered Assurance approach was appropriate for all market participants.
• Greater consultation required for significant dates e.g.
– Go-live date , schema release, IPT window
Documentation• Market documentation was comprehensive and
straight forward to complete.
• Request for the test scripts to be more descriptive for testing requirements.
IPT• A higher number of incorrect market messages were
sent into Networks compared to previous MDU’s.
• Networks were unable to receive/send messages for a period of time due to the test hub being down.
• Most market participants kept to the agreed IPT schedule but there were some significant deviations which resulted in the re-scheduling of timeslots for some suppliers.
• Some market participant evidence submissions were not provided in a timely manner.
Cut-over• RMDS/ESBN were co-located for cut-over and this
was found to be beneficial.
• RMDS staff commended for their assistance and support during this phase.
Communication• All market participants thought communication with
RMDS & Networks was very good particularly during cut-over.
• Market participants were happy with communication with Gemserv.
• Market participants were aware of all fixed dates for this MDU.
• Update e-mails from RMDS re: hub issues are favoured.
Areas for future improvement• Future Market Design Updates for gas and
electricity should not coincide as this puts a strain on internal IT resources (Supplier x 1).
• The format of market messages to be strictly adhered to in testing (Networks).
• Suppliers would like the technical instructions for future MPCC upgrades to be clearer (Supplier x 2).
• More robust controls should be in place for future MPCC upgrades (Supplier x 1).
Areas for future improvement• More testing is executed prior to any future MPCC
upgrade (Supplier x 1).
• Step by step instructions to be provided with test scripts (Supplier x 1).
• Market participants to have greater input into the prioritisation of market change requests (Supplier x 1).
• Suppliers would like future MPCC cut-overs to occur either out of hours or at weekends (Supplier x 2).
Areas for future improvement• Cut-over should not happen at the end of the month
as it clashes with suppliers invoicing cycles (Supplier x 1).
Overall• Overall methodology for the June 2010 Market
Design Update Programme was deemed suitable.
• Some improvements have been identified.
