Quantities of natural gas transported

Raw data, i.e. not corrected for weather vagaries

The quantities of natural gas transported by GRTgaz are calculated:

  • either as the sum of inputs into the network (LNG terminals, other transmission networks, storage extraction),
  • or as the sum of the outputs from the network (other transmission networks, consumption, injections into storage).
Period 2017 2016 2017/2016
Inputs into the GRTgaz network
LNG terminals 103.4 TWh 79.5 TWh + 30%
From other transmission networks 451.1 TWh 452.9 TWh - 0.4%
Storage extraction 72.8 TWh 84.7 TWh - 14.1%
Outputs from the GRTgaz network
To other transmission networks 102.5 TWh 72.7 TWh + 41.0 %
Consumption*
467.0 TWh 465.3 TWh + 0.4 %
Storage injections 57.8 TWh 79.1 TWh - 27 %
Total quantities transported 627.3 TWh 617.1 TWh + 1.6 %
*- These are quantities consumed by the large consumers connected directly to the GRTgaz network, by consumers connected to the public distribution networks
supplied by GRTgaz and by GRTgaz itself for its own needs, in particular the operation of its compression stations.
