Registration Lockdown Period - New 

On Tuesday 17th April the SEM Committee made the decision to delay the launch of the new I-SEM market until October 1st 2018. 

The Transitional Registration Plan indicated the need for a lockdown of registration changes for a period pre and post Go-Live.

During this time no structural entity changes will be allowed e.g. new Parties, Participants, Units. This action is deemed prudent as the most common cause of production system issues can relate to changes in Registration information and data. This lockdown will allow for greater stability for Market Trial, cutover and smooth transition to I-SEM operations for all parties. It is necessary to enact a registration lockdown period as outlined below:

***This does not allow for the full 10 working days for the System Operators to approve VTOD directly in the Market Systems, however the System Operators have agreed to work with the Market Operator to validate VTOD on a reasonable endeavours basis where market participants have submitted their proposed VTOD changes by email to the System Operators by 28/09/2018.

 

These and other important milestones pre and post Go-Live will be included in the Participant Cutover Guide which will be revised based on the new go-live date and published on the SEMO website.

If you have queries on these dates please contact the registration@sem-o.com or I-SEMregistration@sem-o.com teams directly.
