Agenda

• The SEM will continue to operate as an all-island market in the event of a ‘no deal’ Brexit .

• In a ‘no-deal’ Brexit scenario the implications for the day ahead and intraday cross border markets are:

– Day ahead market : • An all-island local day ahead market will continue • There will no longer be day ahead cross border trade

– Intraday market: • Will continue as is, including cross border trade

• SEMOpx will work with relevant parties to implement new cross border arrangements, should they be

needed, but this will not be available on day 1 post a ‘no deal’ Brexit.

• On day 1 post a ‘no deal’ Brexit the key difference will be the removal of the cross border day ahead auction but all other elements of the trading arrangements will remain the same.

• Further details on intended trading arrangements for the SEM under a ‘no-deal’ Brexit are provided in communications by the SEM Committee (the decision making authority for SEM matters) in a notice to industry and the Northern Ireland Utility Regulator in an information note. The Department for Business, Energy and Industrial Strategy has also published a Technical Notice to stakeholders in preparation for Brexit.

Status Update

The Repricing solution was delivered in Release D but failed test due to a number of defects;

We are prioritising the resolution of the outstanding defects with our vendor;

Release D ‘part 2’

Further retesting of the system will be required on deployment of the updated

code. This includes two to three weeks of analysis (in test) post deployment.

Two main components that determine when repricing will commence:

Successful testing and deployment of the Repricing solution;

Outcome of the ”Repricing and Price Materiality Threshold Parameter Consultation”

Repricing

SEMO review of options posed based on current work-plan.

Proposal Status

1. Apply 5% PMT SEMO do not currently have a repricing solution capable of applying a 5% PMT. To implement this solution would mean repricing would not commence until at least Q4 2020.

2. Apply 0% PMT until an I.T Solution is available.

Status update discussed on the previous slide.

3. Urgent Modification to amend Section E.3.8 on a temporary basis with the intention of not carrying out (or suspend) repricing from 1 October 2018 to 11 June 2019.

SEMO would turn attention to implementing a solution that can apply a 5% PMT for future periods requiring repricing.

4. Urgent Modification on an enduring basis in order to require any repricing to be completed by the 13th month after the trading date at the latest.

If a 0% PMT was applied, the plan for option 2 would apply, albeit a number of months would not be repriced as they would fall outside of M+13 timelines. If however the intention was to apply a 5% PMT, SEMO would not have a solution in place by M + 13 for any periods requiring repricing, and therefore would be unable to reprice 1st October 2018 to 11th June 2019.

Settlements : Oct 2019 data process updates

Key points for Sep/Oct 2019:

• Additional delays & catch-up days in Sep and Oct mainly due to delays and corrections required with MDP data, Instruction profiling processing issues and additional processing re-runs required . Sequential nature of processing requirements also has an impact.

• The above issues also had a knock on impact to Settlement Document Delays in September
