Potential Nexus Topic: Universal Single Meter Point Supply Points Simon Trivella –19th April 2011 Project Nexus Workgroup

Background Supply Point (UNC TPD G 1.1.1(a) a "Supply Point" is a System Exit Point comprising the Supply Meter Point or Supply Meter Points for the time being registered in the name of a User Pursuant to a Supply Point Registration… Must comply with the Single Premises Requirement Owned or occupied by one person; In close geographical proximity to each other; Comprised within a common curtilage; and Which serve each other in some necessary or reasonably useful way

Questions for Nexus Workgroup Are there benefits to limiting a Supply Point to only comprise of a single Supply Meter Point (i.e. one MPRN per Supply Point)? Are there disadvantages within / outside of UNC arrangements? Would this be beneficial to include as a Nexus topic/issue? If so, what could/should be done “pre-Nexus”?

Potential Benefits? Remove system and commercial complexity for all? Simplify future system build under Nexus More cost reflective charging? LDZ Transportation Charges are at Supply Point Level Aggregated SOQ for Capacity Charges result in “band shift” Use of flat rates for Customer Charges Alignment with smart metering / electricity arrangements? Supply Point data at Meter Point level (e.g. Market Sector Code) Treatment in Emergency arrangements (e.g. load shedding)?

Potential Disadvantages? Misalignment with supply contracts? Increase in charges through disaggregation? Increase in the number of Supply Points? Additional work / complexities in disaggregation? Potential for disaggregated SPs to not meet certain thresholds? SSP/LSP, DMM, DMV, DME, Interruptible eligibility etc.

Next Steps? Take away for consideration and future discussion Bring back to next Nexus Workgroup meeting; or Allocate to an existing Topic Workgroup? Consider short term solution? Restrict ‘Single Premises Requirement’? Transition arrangements required? Discuss in parallel at Distribution Workgroup?
