There will be a period of planned downtime on MODIS (Market Operation Data Interface System) on Wednesday 16 August 2017 between 13:00 (BST) and 15:30 (BST).

MODIS sends Loss of Load Probability (LoLP), De-rated Margin (DRM), REMIT and Transparency data from National Grid to the Balancing Mechanism Reporting Service (BMRS). Users will be able to submit data via SFTP to MODIS during the downtime and this data will be queued and processed after the outage has completed. No REMIT or Transparency data will be sent to BMRS until after the outage. In addition, users will also not be able to login via the web application.

National Grid does not expect its internal European Transparency Regulation (ETR), LoLP and DRM data reporting to be affected during this planned downtime. However, if LoLP and DRM data is affected, it will not be published retrospectively, which is in accordance with the BSC.
Participants who submit REMIT data via the ELEXON Portal will not be impacted and National Grid’s Balancing Mechanism (BM) systems will also be unaffected by this planned downtime.

In order to avoid any delays in processing your REMIT and Transparency submissions National Grid has requested participants submit all relevant messages before 13:00 (BST). Otherwise Parties are not required to take any further action but note the impact of this planned downtime.
If you have any questions please contact bscservicedesk@cgi.com.

National Grid has informed us that there will be a period of planned downtime on MODIS (Market Operation Data Interface System) on Wednesday 9 August 2017 between 13:00 (BST) and 15:30 (BST).

MODIS sends Loss of Load Probability (LoLP), De-rated Margin (DRM), REMIT and Transparency data from National Grid to the Balancing Mechanism Reporting Service (BMRS).

ELEXON has been advised by one of the Market Index Data Providers (MIDPs), EPEX SPOT power UK, of a planned outage due to take place on Tuesday 8 August 2017 between 19:00 (BST) and 21:30 (BST).

This means the Market Index Data used to calculate the Market Index Price will not be provided to BSC Central Services by this MIDP for Settlement Periods 42-44 (inclusive).

Currently, we are seeing delays of approximately 90 minutes in the receipt of ‘Acknowledgements’ from the Electricity Market Fundamental Information Platform (EMFIP). This system is used by ENTSO-E to publish European Transparency Regulation (ETR) data sent by National Grid via the Balancing Mechanism Reporting Service (BMRS).

The ETR data is still being published on BMRS and EMFIP.

Please note that the BMRS website, APIs, Data Push Service and TIBCO feed remain unaffected by this issue and are operating as expected.

There will be a planned downtime for the Balancing Mechanism Reporting Service (BMRS) between 17:00 (BST) and 20:00 (BST) on Tuesday 1 August 2017. This planned downtime is required for maintenance purposes.

IT system maintenance will take place between 9:00 (BST) and 18:00 (BST) on Saturday 5 August 2017.  This is an ELEXON IT systems outage and will not affect the BSC Central Systems.

The outage is due to necessary maintenance on ELEXON’s internal infrastructure.

During the outage, the networks will be intermittently unavailable; therefore, we will be unable to receive TIBCO messages, which are used for calculating the Balancing Mechanism (BM) Prices. As a result, the BM Prices for Settlement Day Saturday 5 August 2017 may be less reliable than usual. This will not be corrected until we have data from the Interim Information (II) run for this Day.

Further to ELEXON Circulars EL02681 and EL02682 we have now resolved the issue affecting the Data Push Service.
We will continue to monitor the Data Push Service over the next few days and provide any further updates if necessary.

National Grid has informed us that there will be a period of planned downtime affecting MODIS (Market Operation Data Interface System) between 18:00 (BST) and 20:00 (BST) today, Thursday 20 July 2017.

During this period of planned downtime MODIS will not send Loss of Load Probability (LoLP), De-rated Margin (DRM), REMIT and Transparency data to the Balancing Mechanism Reporting Service (BMRS).

National Grid’s Balancing Mechanism (BM) system data will continue to be published on the BMRS during this planned downtime.

Please be aware that we are continuing to experience intermittent issues which are affecting the connectivity to the Data Push Service (DPS). This could result in some users not receiving messages despite being connected.  We are working with our Service Provider to identify the root cause and we will provide further updates during the course of this investigation.

Although the Data Push service is still available, users may notice brief periods of instability whilst this problem persists. During these brief periods, some users may not receive the messages in a timely manner and those missed messages will be recovered thereafter. The BMRS website, the Application Programming Interfaces (APIs) and TIBCO service are unaffected by this issue.
