Congestion Management Procedures

If both a Firm Storage Service and an Interruptible Storage Service are used by the Storage Customer at the same time, then:

• in case of the withdrawal of Gaseous Fuel by such Storage Customer, the volumes of Gaseous Fuel kept in storage under an Interruptible SSA shall be delivered in the first place, provided that such withdrawal does not affect the created mandatory stocks, subject to the principle set out in section 4.2.12. of the Storage Code, which applies in case of the withdrawal of Gaseous Fuel kept in storage in the Additional Working Volume made available as part of the Extension of Offered Services;
• in case of the injection of Gaseous Fuel at the request of such Storage Customer, the Gaseous Fuel is first recognised as volumes kept in storage as Firm Storage Service, and subsequently as Interruptible Storage Service, subject to the principle set out in section 4.2.11 of the Storage Code, which applies in case of the injection of Gaseous Fuel for storage in the Additional Working Volume made available as part of the Extension of Offered Services.

The SSO may interrupt or restrict the provision of Interruptible Storage Services in each of the following cases: (a) when this is necessary for ensuring the undisturbed provision of Firm Storage Service by the SSO, (b) in order for the SSO to fulfil its obligations resulting from the Stockpiling Act, in accordance with section 8.2 of the Storage Code, (c) the situation indicated in section 2.3.1.24 of the Storage Code occurs, (d) in case of reduced capacity for the transport of Gaseous Fuel at MFPWE_OSM or MFPWY_OSM. The duration of interruption or restriction in the provision of Interruptible Storage Services shall depend on the level of UGS or CUGS filling.
