SIT Settlement High Level Testing and Data Approach Guidance 

The Programme has published SIT Settlement High Level Testing and Data Approach Guidance to support SIT participants during Settlement Testing. You can view this guidance document below:

SIT Settlement High Level Testing and Data Approach Guidance

Settlement Testing in SITB started on Monday 10 June 2024 and will prove the accuracy of Settlement processing and reporting. 

Elexon will produce a “Settlement Input Report” which will enable Programme participants to compare the settlement inputs (i.e. the Meter Point Administration Number (MPAN) consumption provided, estimations etc.) with the “REP” settlement reports. A small number of MPANs will be used to support this testing. Each cohort will be assigned an average of 50 MPANs (400 in total), each settlement day and the subsequent runs will use these 400 MPANs. 

If you have any questions about Settlement Testing, please email the Testing team at [email protected]
