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
• perational 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

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
