  1. iGT Agency Services migration considerations • As part of UK Link replacement programme (incorporating industry requirements) the new systems will need to be populated with data to enable the services to be available • For settlement reform the migration / cutover of GT data is a reasonably straight forward affair as Xoserve will have most of the data • For iGT Agency Services the situation is different as Xoserve doesn’t currently hold the data, the existing data may not be fit, or complete, for the new arrangements and work in progress may further complicate matters

  2. iGT Data Mapping • There are several iGT organisations • An iGT organisation can have one or many iGT Licences • Under each iGT Licence are the CSEPs • Under each CSEP are the MPRNs • Under a CSEP there may be a nested CSEP(s) under which are its MPRNs • The mapping of the MRPN to CSEP to iGT Licence to iGT Organisation is essential to enable the services to be performed • A new CSEP Id is expected to be utilised to support this mapping • iGT, GT and Shipper will need to align to the mapping

  3. Implementation matters • The iGT Agency Services will require other parties to implement new processes and supporting system changes, these parties include: • iGTs • GTs • Shippers • Many of the processes between iGTs and GTs do not directly involve Shippers but are essential for the arrangements to work effectively. • It is expected that parties will be provided with information during migration and after cutover for verification etc

  4. Migration and cutover New live system Migration and data preparation (months) Cutover period (days) supported by Mods for non-effective days Work in progress

  5. Migration and data preparation iGTs GTs The migration and data preparation activities may include: Data preparation Initial data load and mapping Final preparation Data population Work in progress Portfolio reporting Testing Shippers

  6. Migration and data preparation • Possibility that the iGT and GT process interactions are implemented early • Some data not held by iGTs, either populated or recognisable default allowable value used • Some data may need to be populated by Shippers • Migration data e.g. Class types, is required from Shippers • Portfolios are expected to be provided to enable all parties to validate their records • Data to be provided to parties detailing the “mapped” data • Records to be maintained (available to industry) of mapping event and any default values • Historic data needed for settlement products e.g. read data • Ongoing data e.g. meter reads and supply point events e.g. change of supplier, change of asset – updates required.

  7. Examples of missing data

  8. Industry input is welcomed • Any matters (ideas, concerns, requirements etc) industry parties consider are relevant – please let Xoserve know • To create these arrangements an iGT UNC modification may be required
