IT notices: upgrade to the EDT service on 8 November 2018

National Grid will be upgrading their systems between 09:00 and 14:00 on 8 November. During this time, Market Participants may experience connectivity issues with Electronic Data Transfer (EDT) which may affect Gate Closure Data (PN and BOD) submissions.

How will I be affected?

During the upgrade, Market Participants may notice intermittent connection issues with EDT. National Grid advises participants who lose connectivity to reconnect on a secondary connection and resubmit the data. For participants who do not have a secondary connection, National Grid advises to try resubmitting after a few minutes.

For both types of connection please try to ensure Gate Close Data (PN and BOD) are submitted in a timely manner in case there is an issue at the half hour end.

MODIS and REMIT data

Market Participants who use the Market Operation Data Interface System (MODIS) to submit European Transparency Regulation (ETR) and REMIT data can continue making their submissions.

However they may not receive acknowledgments that the data has been received. In such cases, Market Participants can check whether their submission is published on the REMIT or ETR data page of the Balancing Mechanism Reporting Service (BMRS).

Services not affected

Market Participants who currently submit their REMIT data via the Elexon Portal will not be impacted by this scheduled maintenance and BMRS will continue to publish all data as normal.

This is not a Balancing Mechanism (BM) outage and National Grid intend to carry out a similar infrastructure upgrade on 15 November 2018.

What do I need to do?

You do not need to take any specific action but please note the impact of the infrastructure upgrade.

Do I need to take any further action?

No
