AER - Prefilled indicative Basis of Preparation - TNSP - January 2025

We consulted with the NSPs to develop the data reporting workbooks. Issues raised and our responses to these issues are provided in the Issues Register. 

Note: The Issues Register was updated on 31 January 2025 to include issue numbers 62-74.

In response to issues raised seeking guidance on the Basis of Preparation referencing, we have prepared prefilled Basis of Preparation files for the NSPs. These files have Data Submission Workbook tables and corresponding Worksheets and Data Categories prefilled to help NSPs meet the Basis of Preparation requirements. 

We have mapped new data requirements to previous data requirements. While the Orders replace the previous regulatory information notices and information requests, many of the data requirements remain the same. To assist with NSP reporting, the data reporting workbooks follow the structure and table numbering as the RIN reporting workbooks. We have attached a 'RIN to Orders' mapping file to assist users with comparing data tables between the two reporting template sources. 

A Glossary of terms and definitions is provided to assist NSPs and other interested users with understanding terms used in the tab names, row descriptors and column headings.
