Coronavirus (COVID-19) Customer Update – 3rd August 2020

Coronavirus (COVID-19) Customer Update

Published on 03 Aug 2020

Dear Customers,

I’d like to share my latest update as we continue to support you through the ongoing challenges and impacts of the COVID-19 outbreak.

As we see greater use of regional and local COVID-19 restrictions, it is worth highlighting that the temporary facilities introduced by Urgent Modifications 0722 and 0723 are only available to sites that are mandated to be closed by the latest regulations from the appropriate regional Government.  This means that submission of Estimated Meter Readings as actuals and use of the Isolation Flag for low/non-consumption can only be used for sites which are not permitted to open.  Any site which could be open but has chosen not to (or is unable to open for other reasons) should not be using these facilities.

As restrictions ease, I encourage Shippers or Suppliers to review any sites that they have set to Isolated since the start of lockdown to assess whether they are now capable of flowing gas and should be ‘re-established’.  It is also very important that we receive true actual meter readings for as many sites as possible.  We report the aggregate Annual Quantity (AQ) of sites without a recent meter reading to the Performance Assurance Committee each month, and that figure has risen noticeably during the year.  At the start of July, it stood at over 60bn kWh of AQ (60 tWh or nearly 12% of total AQ across all Local Distribution Zones).  You can view the statistics here. Your Customer Advocate can share your anonymous code with you if you are not already aware.  We realise that lockdown has seriously hampered meter reading activities, but we hope that Shippers, Suppliers, Meter Read Agencies and Consumers can now work together to get more meter reads into Settlement and help to correct the unusual Unidentified Gas trends that we have seen since mid-March.

We continue to track and report Unidentified Gas (UIG) on a weekly basis.  You can always find the latest Interim UIG Reporting graphs on our website - under UIG useful links.  We are currently seeing more volatility than usual between the first and subsequent runs of Allocation, especially in Wales South (WS) Local Distribution Zone.  This appears to be due to actual measurements from a single large Daily Metered site, which are arriving too late for the first run of Allocation.  The position is corrected as soon as the actual measurement arrives.  We realise that this adds extra uncertainty to UIG Allocations, and we are working with National Grid and with Wales & West Utilities (the Network Operator for Wales South) to understand and address the root cause.

Our next update will be on Monday 17th August. If you have any queries about our continuity planning, please email We’ll respond to every email we receive within 24 hours.

Kind regards,

Andrew Szabo | Chief Customer Officer
