CP1071 – Amendment of SVAA and PARMS decimal place issue

Formal title: Amendment of SVAA and PARMS decimal place issue

Summary

A discrepancy has been identified between the number of decimal places in certain PARMS data items provided by the SVAA for use in the Supplier Charges calculation and the requirements specified within the BSC. In Annex S-1, section 3 (Charges), the Code states that percentage performance data used for calculating Chargeable MWh values for Serial SP08 should be rounded to 2 decimal places. However, since 1998 this data has only ever been provided by SVAA to 1 decimal place. As a result, while the actual calculations have been performed correctly, the discrepancy has led to some errors in the values charged and redistributed to Suppliers.
