Currently there is Network Exit Agreement Indicator visible in DES within community and portfolio view for Shippers and portfolio view only for DNs and IGTs.

The purpose of this indicator is to confirm where a consumer has entered into a bilateral Network Exit Agreement (NExA) with the relevant Transporter.

Currently the process for the NExA indicator to be updated is not established, preventing the Transporters being able to provide this information. The process to update this information should be established as part of this Change Proposal which will ensure the data held in UK Link and DES for these sites is accurate.

This change seeks to conduct a data cleanse against the information held in UK Link and DES for NExA sites and to ensure the ongoing process is put in place to allow Transporters to confirm where there are any updates and for this to be recorded accurately within UK Link and DES. This will ensure that the indicator within DES remain as per the latest position.

This will involve removing the indicators currently recorded in UK Link and DES for NExA sites. DNs and IGTs must provide an updated list of NExA sites to the CDSP. This updated list must be reflected in UK Link and DES. 

For the avoidance of doubt, this change does not involve holding any additional data within UK Link or adding any further data items to DES, but simply cleansing what we currently hold and maintaining this information, ensuring it is accurate.

To confirm, Modification 0701 - Aligning Capacity booking under the UNC and arrangements set out in relevant NExAs has been raised to improve visibility where a consumer has entered into a bilateral Network Exit Agreement (NExA) with the relevant Transporter, and to link capacity increases with the NExA so that the allowed capacity does not exceed the capacity as agreed in the NExA. This CP is not dependent on this Modification being implemented, however it will support it and therefore is being proposed to be delivered ahead of Modification 0701.
