Annex F
Article 9 – Example of a Discount
Reduction at Storage Facilities with
Access to More than One System
As a default rule, the TAR NC states that storage tariffs require a 50% discount, with
the potential for higher discounts up to 100%. However, there is the potential for an
exemption where the location of storage results in the entry and exit of gas being
used as an IP.
Such storage facilities that are connected to several systems and are actually used
as IPs constitute a minority of storage facilities across Europe. In practice, the
commercial handling of these storages differs from one MS to another. This Annex
aims to provide a panorama of the different approaches used by European TSOs
connected to such storage facilities.
The approaches currently followed in Austria, France, Germany, the Netherlands
and Slovakia are described hereafter. They may have to change to ensure compliance
with the TAR NC.
Storage facilities allowing for cross-system use in Austria
Gas Connect Austria, the Austrian TSO concerned by such storages, applies
discounts for all storage facilities. They are based on tariffs derived from the
reference price methodology, an equalisation adjustment, and tariffs cannot in-
crease beyond a certain threshold which is defined by comparison with the last
regulatory period.
Only one account per entry-exit system side is currently used at such specific
storages.
