Nitrogen storage report
If a lot of nitrogen is being used, part of this nitrogen will come from the "Firm Volume Restricted" section (see Nitrogen report). The 'nitrogen storage meter' and related graphical or numerical retrievals provide information about the volume of nitrogen available in the nitrogen storage.
Nitrogen storage meter
The nitrogen storage meter shows the most up-to-date status of the volume of nitrogen available in the nitrogen storage (in m3(n)). The meter scale runs from zero (bottom left) to the maximum volume of nitrogen in the storage (bottom right). This scale contains four colours. There is a dark-green section on the right, if the volume of nitrogen available is shown to be in this area the nitrogen storage is to be used as normal. In the middle is an orange section, if the nitrogen volume reaches this area a REMIT warning is sent, see below. The red section shows the reserve quantity of nitrogen in the storage. If the actual, available quantity of nitrogen reaches this area, the nitrogen storage can no longer be used (including REMIT report, see below). If the light-green section is reached from the dark-green section, there is no alarm. If a REMIT report was sent, this is only withdrawn if the pointer leaves the light-green area and moves towards the dark-green zone. The pointer on this scale shows the actual working volume available. The value shown under the meter gives the working volume from the pointer until the red section.
Nitrogen storage graph
The nitrogen storage graph shows the volume of nitrogen available per hour in the past 14 days (in m3(n)). The same areas and colours are used as those on the nitrogen storage meter. The yellow line shows the actual working volume at the end of every hour.
The nitrogen report above shows the actual and maximum working volumes of the nitrogen storage (in m3(n)). Users can choose from various aggregations (hour, day, month, calendar year and gas year) and various periods.
Nitrogen storage volume and REMIT reports
REMIT reports will be issued as soon as there is hardly any working volume available in the nitrogen storage.
- Nitrogen volume in the orange area (see nitrogen storage meter). An advance notification/warning is issued to indicate that the nitrogen storage is almost empty. Market participants are asked to adjust their H-gas/G-gas balance to reduce nitrogen use.
- Nitrogen volume in the red area (see nitrogen storage meter). Nitrogen is being used from the nitrogen storage reserve capacity. A REMIT report is issued to indicate that the nitrogen storage is empty. Market participants may be called upon to adjust their H-gas/G-gas balance to reduce nitrogen use.
- Nitrogen volume moves from the light-green to the dark-green area. If a REMIT report was issued previously, this is withdrawn.
