The solution proposed by Gemini application support is, no changes on the meter end date and set active process. On the meter end date process the Nomination status is changed to ‘N’ as mentioned in the SUC however the Nomination values will not be changed. This enables the system to approve the Nominations by the Nomination approval batch job. I.e. the nominations are cancelled during processing the end date record, however the values are not changed. Later if the meter is set active by second record, the Nomination with N status will be picked by the job and approves it. If meter is not active nomination is left unactioned.


The Gemini Project team, along with the SMEs have recommended to change the functionality in MDS file loading job, the process of cancelling the nomination to be completely removed in MDS file load and introduce a new job which cancels the Nomination of all inactive meters that runs after MDS file loading job.


The CDSP need to provide costs to National Grid for both options to agree which is the preference.
