National Grid ESO (NGESO) have confirmed timings of the planned infrastructure maintenance activities which will impact the Electronic Data Transfer (EDT) and Electronic Data Logging (EDL) network connections over a period of four weeks. These timings are now listed below.

  • Tuesday 22 February 2022: 10:10 – 14:00 (GMT)
  • Thursday 24 February 2022: 10:10 – 14:00 (GMT)
  • Tuesday 1 March 2022: 10:10 – 14:00 (GMT)

What is happening?

Further to Elexon Circular EL03509, National Grid ESO (NGESO) has confirmed that the planned infrastructure maintenance activities had to be postponed. National Grid ESO has now provided new dates for when this maintenance work will take place. This will impact the Electronic Data Transfer (EDT) and Electronic Data Logging (EDL) network connections. The new dates and times are listed below:

  • Tuesday 18 January 2022: 10:10 – 14:00 (GMT)
  • Tuesday 25 January 2022: 10:10 – 14:00 (GMT)
  • Tuesday 1 February 2022: 10:10 – 14:00 (GMT)
  • Tuesday 8 February 2022: 10:10 – 14:00 (GMT)

How will I be impacted?

These works will potentially interrupt EDL and EDT connectivity for a short period of time on each date. No specific timings for this have been given. 

It is expected that approximately a quarter of all EDT and EDL connections will be impacted on each day depending on the resilience set up of the station. If a party loses connectivity to EDL or EDT they should try using the reserve connection, or retry a short while later. 

Please make your IT teams responsible for EDT and EDL communications aware of this planned work, and make your control points aware that they may need to take telephone instructions from the Electricity National Control Centre (ENCC). 

Do I need to take any further action?
