National Grid MODIS unplanned downtime due to system failure

National Grid MODIS unplanned downtime due to system failure

What is happening? 
From around 23:00 (BST) last night, 13 August 2018, National Grid experienced a fault with their MODIS system which prevented certain reports being generated and also temporarily prevented Market Participants from sending files to MODIS. The service was fully restored by 06:00 (BST) this morning, 14 August 2018. During this time, data from MODIS was not sent to the Balancing Mechanism Reporting Service (BMRS).

As BMRS did not receive data, Reserve Scarcity Price (RSP) was defaulted to zero, for the impacted Settlement Periods (SP). De-rated Margins (DRM) were high during this period, so this is the same outcome as if MODIS had been publishing the data correctly.

How will I be impacted?
The main impact of this fault is that Load Probability (LoLP) and DRM files from Settlement Period (SP) 48 last night to SP14 this morning were not submitted to BMRS, along with other ETR reports. In total, there is a gap for 15 periods missing on the BMRS website.  National Grid is currently investigating the reason for the failure and is actively monitoring MODIS.

What do I need to do?
Parties are not required to take any further action but note the potential impact of this system failure.
