Project Nexus Data Cleansing initiative 1

Background  To enable Shippers to take full advantage of their requirements specified under Project Nexus data must be in a fit state to support commercial operations  Data Cleansing has been a topic at GT industry for a for 18- 24 months  Data items that have the potential to negatively impact the gas settlement regime have been identified and Shippers provided with individual portfolio information to aid data cleanse and update activities  As the industry moves into the iGT Data Preparation phase some iGT supply point data will require cleansing

Background  An informal Data Cleansing Workgroup has been created  This meets monthly and comprises Xoserve and Shipper operational representatives  Topics are discussed, industry level figures presented and progress towards resolution monitored  Either this group needs to be extended to cover iGT data items or a new or existing iGT group is formed to progress the matters expected to arise  The regular attendees at the Data Cleansing Workgroup are shown on the last slide

GT data topics relevant to iGT Data  The following is a sub-set of the GT data cleansing topics that are likely to be relevant to iGT data, additional iGT specific data items may be identified during the iGT Data Preparation exercise.  Correction Factors of zero  Potentially incorrect Correction Factors  No reads for >4 years  No reads for > 3 years  No reads for > 2 years  Confirmed no asset  Read factor / units  Invalid meter models  All of these data items, if incorrect, will impact the gas settlement process

GT data topics relevant to iGT Data  In addition, Xoserve has raised at several of its CSEPs workgroups the need for completed reconciliations prior to cutover  Xoserve shall add this topic to the iGT Data Cleansing Register  Xoserve would welcome the iGT Shipper Workgroup views as to whether to:  Incorporate iGT topics within the existing Workgroup (with, if required, a summary update to the iGT Shipper Workgroup)  Utilise an existing iGT workgroup  Create a new workgroup for iGT data cleansing topics
