Infrastructure maintenance on BSC Central Systems and ELEXON Portal

What is happening?
There will be a period of planned downtime on the BSC Central Systems applications from 17:00 (GMT) to 23:59 (GMT) on Wednesday 27 March 2019. This outage is required for the infrastructure maintenance of the BSC Central Systems and will impact the Supplier Volume Allocation Agent (SVAA), Performance Assurance Reporting and Monitoring System (PARMS) and ELEXON Portal.  

How will I be affected?
The SVAA and PARMS will not be available during the planned downtime.  As this outage is outside of the service-operating window, there will be no impact to Parties.

The ELEXON Portal log in will be disabled and therefore users will not be able to access services from the ELEXON Portal. If you are using the ELEXON Portal to submit REMIT messages manually via the Portal Graphical User Interface (GUI), you will not have access to the GUI. Please ensure you submit any data ahead of the outage window. If you are currently using the ELEXON Portal POST API interface ( to submit your REMIT messages, the service will be available with the exception of two periods lasting up to one hour; these periods are expected to be between 17:30 (GMT) to 18:30 (GMT) and 22:00 (GMT) to 23:00 (GMT).

What do I need to do?
If you request data from the ELEXON Portal or submit REMIT messages manually, please ensure you access the ELEXON Portal ahead of the maintenance timescale. For REMIT API users, please avoid submitting your messages during those slots mentioned above.   

Is there anything else I need to know?
