TAR NC Implementation Document – Second Edition September 2017
To sum up, in Germany there are 4 simple configurations at storage facilities
connected to more than one entry-exit system (other configurations exist, where
network users partly transfer gas and partly withdraw it into the TSO system from
which it was previously injected, but these configurations are not considered here):
\\
Case 1:
The network user registers on the non-discounted account of the
storage operator, and they transfer gas from an entry-exit system to another. In
such case, the storage facility is simply used as an IP. The network user pays
what they should pay if the storage was an IP (no discount), there is no discrim-
ination against a competing IP, and
there is no discount reduction
.
\\
Case 2:
The network user registers on the discounted account of the storage
operator, and they do not transfer gas from an entry-exit system to another. In
such case, the storage facility is simply used as a ‘standard’ storage facility. The
network user pays what they should pay for any ‘standard’ storage facility (the
50% discount), there is no discrimination against an IP since the storage facil-
ity is not used ‘as an IP’, and
there is no discount reduction
.
\\
Case 3:
The network user registers on the non-discounted account of the
storage operator, but they do not transfer gas from an entry-exit system to
another. There is no discrimination against an IP since the storage facility is not
used ‘as an IP’.
There is no discount reductio
n, since no gas is flowed between
entry-exit systems.
\\
Case 4:
The network user registers on the discounted account of the storage
operator, but they transfer gas from an entry-exit system to another. In such
case, the storage is used as an IP. To avoid discrimination against some network
users, a
discount reduction applies
.
Storage facilities allowing for cross-system use in the
Netherlands
Gasunie, the Dutch TSO, currently applies a 25% discount at all storage connection
points, regardless of whether they are ‘regular’ or ‘cross-system’ storages. No trans-
fer fee is used.
Only one account per entry-exit system side is used.
The process of implementing the TAR NC may alter the provisions at storages
allowing for cross-system use.
Storage facilities allowing for cross-system use in Slovakia
Eustream, the Slovak TSO, has recently applied a reform whereby there is one single
domestic entry-exit point. This point covers connection to the TSO, to DSOs and to
storages. Therefore, one single entry and exit tariff applies in Slovakia for distribution
and storages, implying the lack of a discount for storages currently. Cross-system
storages in Slovakia are connected both to the Eustream TSO system and to DSOs
and the Austrian TSO system of Gas Connect Austria.
Only one account per entry-exit system side is used.
