This Modification has been developed through the VASMG following the raising of Issue 11 by Scottish Power plc, Centrica plc and E.ON UK. Annex S-1 of the Balancing and Settlement Code, requires that Suppliers increase the amount of actual energy provided to Settlements so that by 14 months, 97% of the actual energy rather than estimated energy is submitted. This Modification seeks to revise the current Non-Half Hourly (NHH) Settlement performance measure and the associated Annual Consumption Calculation Process.


The Proposed and Alternative Modifications were rejected by the Authority on 21 November 2005
