BACKGROUND

Mod 640:

• Implemented June 2004

• Aim to encourage Shippers to proactively manage their SSP to LSP crossers in the year

• Only applied to sites were AQ increased by more than 15,000 kWh and 20%

• Excluded sites which had changed supplier during the year

Mod 0095

• Allowed reconciliation of SSP to LSP crossers when there had been a change in the registered Shipper

THE ISSUE

• For SSP to LSP crossers that have changed registered User the old Shipper has no way of validating the Mod 640 charge

• Old Shippers rely on blind faith that the incoming Shipper(s) have correctly managed the site

• We have limited information to support and query the mod 640 invoice

• There are sites which EDF Energy have been invoiced for were all of our data suggests that the site was a SSP during our period of ownership

EDF ENERGY’S VIEW

• Shippers should have access to supporting information to validate the Mod 640 invoices

• For sites that are no longer registered to the Shipper this should include relevant information used for calculating the AQ:• Relevant Meter Readings

• Meter Asset information

• When should this information be provided - with 640 invoice or provisional AQ calculation?

• Once this information is available is there a requirement to develop a process to ensure costs are targeted at the correct Shipper?

• Would this require a dispute mechanism – in or out of UNC?

WAY FORWARD

• Requirement for UNC Review proposal?

• Are there any additional issues/areas that should be discussed?

• Impacts on xoserve’s systems?

• Data protection issues?
