Conversion daylight saving time

25 Mar 2014

On gas day 29 March 2014 there will be a switch from winter time to summer time. This means that this gas day will have 23 hours. To avoid any problems which may occur, please be aware of the following:

  • Gasunie Zuidwending expects nominations according to the EDIGAS protocol. This means that a nomination for this gas day (29 March) consists of 23 hours in which, translated to UTC, the nomination for that day begins at 05:00 UTC (06:00 LET) and ends at 04:00 UTC (also 06:00 LET). When using ENOM with appropriate settings, this feature is facilitated when nominating for this gas day. When not using ENOM, please make sure that Edigas messages will have this timeframe.
  • Whenever possible, avoid sending in nominations in the period between 01:00 LET and 03:00 LET. Due to possible technical limitations, incoming nominations may be handled specially and different from the normal process and thus may introduce extra risks.


On May 20, 2014 Gasunie Zuidwending changed its company name to EnergyStock. This news item was posted by EnergyStock’s predecessor Gasunie Zuidwending before the name change.
