PN UNC Workgroup

Supply Point Register 25th October 2011

2

Objectives of the Workgroups

• Determine detailed business requirements • Consider/review comments made during the Project

Nexus consultation • Review existing Modifications relevant to the topic area• Workgroup deliverables;

– Process maps– Business Requirements Document. Document to

provide sufficient definition around business rules to:• Enable the proposed requirements to be

incorporated in xoserve’s investment decisions, and• Support the raising of any UNC Modification

Proposals• Monitor & align with latest SMIP position • Focus will be on requirements for Project Nexus

delivery

3

Approach & Workplan

• Agree scope – And areas for consideration

• Consider requirements from other Workgroups;– Settlement– AQ– Reconciliation – Invoicing– PN UNC

• Consider any relevant live Modifications – Mod 0357: Enhanced Supply Point Admin. Process– Mod 0353: Population & Maintenance of the Market Sector Code

• Agree future requirements• Develop process maps and detailed business rules

Project Nexus Consultation Responses

Requirement Source

1.5There is a requirement for basic profile data to be provided to allow accurate

quoting and purchasing.Corona Energy

1.7Raise an enquiry on Small Supply Points (SSPs) and receive back the same

information as currently received for the Large Supply Points (LSP).Corona Energy

1.10When a consumer exercises their right to change supplier, the industry needs to

consider if it is prepared to share consumption data with other Shippers.npower

10.6Support multiple suppliers/shippers per legal entity. This would avoid the need for bulk transfers and allow shippers to easily establish parent and subsidiary account relationships to enhance corporate balancing, settlement and invoicing efficiency.

10.13Bad debt risk. There may be merit in xoserve gauging industry’s views on the

merits and practicality of, and need for, maintaining a record of supply points that have a history of bad debt.

11.3

Control of static non-commercial industry data. Data items such as those relating to end users’ address details which are considered to be static should have an increased centralisation of maintenance activities to ensure consistency across

the industry.

13.11More direct relationships between the Meter Asset Manager (MAM) and

xoserveGDF

10.9

Inclusion of Unique Sites database within Nexus. We believe that there are benefits in structuring the core data in such a way that a flexible and fully

inclusive service is provided to cater for all differing contractual relationships that can be associated with Supply Points. The primary

change to xoserve’s services in this respect would be a common platform for all core data, for example Unique Sites, CSEPs etc.

and unique sites.Corona Energy

13.27Systematize processes that are currently managed outside of the core system

Requirements raised in other Workgroups

• AMR & Settlement Workgroup;

– Check Read information• Requirement for the GT to notify the Shipper the date the Check

Read was due [1] month after the Check Read due date.

• In order to do this the relevant data items to monitor the Check Read requirement will need to be recorded by the GT.

– Supply Point Enquiry (Mod 0357)• Provision of consumption data to the Shipper

• BRD already developed, review required

• Reconciliation, Invoicing & AQ Workgroups;– Nothing identified as yet

• PN UNC– Single Meter Point Supply Points– Market Differentiation

7

Proposed Approach for Today’s meeting

• Discuss and agree issues & requirements for each area identified as a business issue

• Some could possibly be closed as no longer an issue

• May highlight new issues

8

Scope?

• Identified areas from IRR & Workgroups for discussion;1. Updating Address data2. Asset data – identify when a check read is required3. Unique Sites4. CSEP’s5. Prime & Subs6. LPG Sites7. Market Differentiation8. Consumption data 9. Single Meter Point Supply Points

1. Address Data

• Requirement to improve address data.• Current principles:

– UIP submits MPRN creation– Shipper / Network submits address update– Xoserve validate against PAF (Post Office Address Format)– If valid, MPRN created/address updated– Invalid: request rejected

• Possible issue with plot addresses– although validation performed there is still a risk of duplicates,

plot address remaining & MPRN set up in incorrect LDZ• Any requirements/improvements to current process? • Any principles/initiatives discussed by SMIP

10

2. Asset Data

• Requirement to record AMR related data for monitoring a Check Read for certain sites– Also need to show if the equipment submits ‘derived’

or actual reads.– Held on the Register against the MPR?

• Is this the only additional asset related data item that needs to be held?

• Raised at a number of meetings the quality of asset data held on UKLink– Opportunity to address under Project Nexus?– Improvements to RGMA flows/validations?

11

3. Unique Sites

• Approx 100 sites (inc. NTS sites & Interconnectors)• Currently processed off line due to complex

arrangements which UKLink system is unable to manage (mainly billing issue)

• Desire for Unique Sites processes to be systematised• Issues

– Shared Supply Meter Points (SSMP’s) require submission of a form signed by all registered/proposing Shippers

– DM CSEPs – Some SPA timescales are different to ‘normal’ sites

12

4. CSEPs

• Assuming that the current arrangements apply, – Receipt of aggregated data– Receipt of specific data at MPR level to carry

out Reconciliation for LSPs (difficult to validate)

– Receipt of MPR & related site data items for the SCOGES service

• Are there any improvements we can make to the current service?

13

5. Prime & Subs

• Approx P&S numbers: – 1,500 Prime meters, 2,960 Subs

• Issues relating to P&S sites (from Xoserve perspective) relate to billing;– Energy from Sub meters must be deducted from the Prime

meter (reconciliation)– AQ of the prime meter should reflect consumption from that

meter only, not consumption of all Sub meters

• Requirements from AQ Workgroup state– Reads will continue to be obtained within a 5 day window– All P&S meters must be processed within the same ‘Product’

(except if DM mandatory)

• Any other issues?

14

6. Liquid Petroleum Gas (LPG) Sites

• Approx 2,000 sites across 2 networks• All details of LPG sites are held on a separate database • Desire for these sites to be included in the scope of

Project Nexus – LPG MPRs recorded on the Supply Point Register would;

• Deliver benefits from managing all Meter Points on one central system

• Ensure duplicate sites are not set up• Utilise existing data flows for the receipt & processing of site

& asset data including receipt of reads (this may be dependent on whether Smart meters are fitted)

• Would mean that LPG sites would need to be excluded from some processes (e.g. allocation)

15

7. Market Differentiation

• Agreed to ‘park’ until later in the requirements definition phase of Project Nexus

• Within the Settlement processes; the market will be differentiated by ‘Product’

• Is there still a requirement within each Settlement process to differentiate via a market sector flag ?– If so is there still a desire to increase the sectors (e.g. SME,

Hospitals, holiday homes)

• What will the MSF provide?– What defines MSF – usage or contract or licence definition?

• SSP & LSP will continue to exist for SPA processes & charging

16

8. Provision of Consumption Data

• BRD produced August 2010• Document details the process for a Shipper to request & receive

consumption data for I&C sites– Market Sector Flag used to validate, Shipper obtains relevant

permission from the consumer– Data provided via Supply Point Enquiry process– Consumption data issued to a Proposing Shipper for the requested

period, potentially daily consumption for a 12 month period• Purpose: to provide additional information to a potential Proposing

Shipper about a Supply Point to enable efficient & accurate quoting– A Proposing Shipper will be as equally well informed as the Incumbent

Shipper • Requirement put on hold until data access principles were set by

SMIP• SMIP principle: understanding appears to be that access to

consumption data will only be provided to the Supplier for the period of their ownership

17

9. Single Meter Point Supply Points

• Requirement from GTs to limit 1 Meter Point to a Supply Point– Removes complexities & simplifies Transportation processes – More reflective of physical arrangements– Consistent treatment for all sites– Cost reflective charging

• over 99% of all Meter Points will have their transportation charges reduced

– Aligns with Smart metering arrangements• Although

– May misalign with supply contracts• Facility to link meter points??

– Increase in transportation charges for some sites• Approx 0.27% (15.6% of LSP market)
