How are Supplier Charges calculated?

The Performance Assurance Reporting and Monitoring System (PARMS) software calculates the Supplier Charges due, each calendar month.

These charges are capped for each Supplier based on energy share within each GSP Group, to limit each Party’s liability in any one reporting period. A GSP Group monthly liability cap is calculated based on its annual energy take for the previous financial year. A Supplier’s monthly liability cap is calculated based on its total active import energy in the reporting period within each GSP Group.
