Quality Measurement Places

The transmission system operator performs the acceptance and transfer of natural gas and the measurement of natural gas quality at the following locations:

Transmission system interconnection Natural gas metering location
Natural gas transmission system of Russian Federation GMS* Korneti (Latvia) un GMS Izborsk (Russia)
Inčukalns Underground Gas Storage Facility GMS1, GMS2, GCP1** and laboratory***
Natural gas transmission system of Republic of Lithuania GMS Kemenai (Lithuania)
Natural gas transmission system of Republic of Estonia GMS Karksi (Estonia)


* GMS – gas metering station
** GCP1 – test line of gas collection point (temporary, during certain technological works), no quality measurements taken
*** No metering done

In 2017 JSC "Conexus Baltic Grid" installed additional chromatograph units in the most important points of gas transmission system in order to precisely measure natural gas in energy units for Latvian natural gas transmission and storage system users:

  • at gas regulation stations:
    1.  (GRS) Riga-1,
    2. GRS Ziemeļi,
    3. GRS Ogre,
    4. GRS Cēsis,
    5. GRS Valmiera-1
  •  gas regulation unit (GRU) Iecava-Liepāja.

Data acquired by chromatograph units is used for natural gas measuring in energy units by the distribution system operator JSC "Gaso".

Points of natural gas composition measuring:

GRS

Natural gas quality measuring points which measure data to determine gas quality for exit points to distribution system operator.
