What is Settlement?
The settlements team is responsible for calculating and initiating payments to Ancillary Service Providers. Each month the team also sends various reports to service providers to allow them to validate these payments as quickly and as easily as possible.
A Preliminary Statement of the ancillary services and also a payment estimate for these services is issued by the eighth business day of the following month that the service was provided. Please note that Preliminary Statements are not produced for the Short Term Operating Reserve (STOR) service.
A Final Statement for every ancillary service, along with the self-bill invoices, is issued by the eighteenth business day of the following month that the service was provided.
