Planned National Grid infrastructure upgrade on Thursday 17 January 2019

What is happening?
National Grid ESO has informed us that there will be infrastructure upgrade on their systems between 09:00 (GMT) and 11:30 (GMT) on Thursday 17 January 2019. During this time, Market Participants will be unable to submit dynamic data via Electronic Data Transfer (EDT)

How will I be affected?
During the outage, the MODIS application will be impacted.
Market Participants who use the MODIS system to submit European Transparency Regulation (ETR) and REMIT data can continue making their submissions via MODIS GUI; however they may not receive acknowledgments that the data has been received or acknowledgements may be delayed.

What do I need to do?
You do not need to take any specific action but just note the impact of the infrastructure upgrade.

Do I need to take any further action?
No, however any BSC Parties having questions for National Grid regarding this planned outage should phone 0800 917 7111 or 0800 085 4806. Overseas callers should use +44 870 521 6121 and quote “NETA EDT”.
