Supplementary reports

Daily storage and LNG operator information

The information contained in this spreadsheet is published on behalf of Storage and LNG Operators under the European Regulation EC 715/2009. The data in this spreadsheet is applicable for the current gas year. Data from previous gas years can be found in the next tab.

Calculated linepack utilisation

The report below collates the hourly supply and demand flow notifications received from NTS connected sites to calculate the NTS linepack minimum value in MCM that would result from these flow profiles. Please note, connected parties update their notifications continually throughout the day; therefore, the report is accurate only at the point of publication. The report is published three times throughout the day (06:00, 12:30 and 18:30) and will reflect latest Linepack and revised supply and demand flow notifications received.

Webinars

We have developed a suite of pre-recorded webinars to provide guidance to the industry to aid decision-making. We are conscious that many of our operational customers work non-standard hours, so we felt that pre-recorded webinars would be beneficial as these can be viewed flexibly at times to suit operational needs.

2017 webinars

Similar to last year, this year’s Winter Webinars have been pre-recorded to help provide more conveniently presented guidance and information. We fully appreciate that many of our operational customers work non-standard hours and therefore felt that pre-recorded webinars would be beneficial as these can be viewed at times that suit individual operational needs.

Having initially reached out to our customers, to ask which subject areas would be useful, the following suite has been put together. This includes:
