Modification 0710S (related IGT Modification IGT148) was raised to obligate the CDSP to take on Class 1 Read Service provision on behalf of Shippers. This was to transfer the obligation to provide the Class 1 Supply Meter Point Read Service from the Transporters to the CDSP. The Change Proposal XRN5218 - CDSP provision of Class 1 read service was previously raised to carry out a novation of the existing contracts currently in place between the DNOs and the DMSPs, across to the CDSP. The decision was taken in June 2021, by the DNOs with the existing contracts in place for the Class 1 read service to continue with the current contracts and service as is until the contract expiry. The current contracts for this service expire on 31 March 2023.

To confirm, the CDSP will not novate the existing contracts for the Class 1 read service, the CDSP will run the procurement exercise to appoint a Service Provider and new contract as of 01 April 2023.


As a result of Modification 0710, it will be the responsibility of the CDSP to appoint a new Service Provider on behalf of Shippers, to provide the Class 1 Daily Read Service from 01 April 2023 onwards.

This Change Proposal has been raised in order to proceed with the procurement exercise to procure a new Service Provider for this service.
