The settlements team is responsible for calculating and initiating payments to ancillary service providers. The team also sends various reports to service providers each month to allow them to validate these payments as quickly and easily as possible. The following sections give more details of the payments and reports.
For most ancillary services provided each month, a preliminary statement of the services and payment estimates for those services is issued by the eighth business day of the following month (preliminary statements are not produced for the STOR service). Final statements for every service, along with the self-bill invoices, are issued by the 18th business day of the following month. For specific dates please see the AS Settlement Timetable.
The following information is sent to all service providers each month – for more information please see the AS Information Presentation.
- Covering letter
- Self-bill invoice
- Statement summary
- Service summaries
- By-unit summary
- Adjustments (if applicable)
- Detailed backing sheets (technical reports)
Paper copies of the invoices and summary statements (service type by day, specific service by day and specific service by unit) are posted each month. The detailed backing sheets (technical reports showing information for each unit, service, instruction & payment) are sent by e-mail.
For a comprehensive reference document on Short Term Operating Reserve (STOR) events of default - please see STOR Events of Default.
The statement reports are currently being reviewed for their content, level of detail, presentation and format etc. Two workshops were held to review the detailed backing information on the 24th February and 3rd March. For a summary of the workshop discussions, including the next steps is available - please see Backing Sheet Workshops.
Following on from the two workshops a proposal to change the Ancillary Services backing sheets is now available - please see Backing Sheet Proposal.
