We offer volume, injection and withdrawal storage capacities as bundled or unbundled products.

To describe our product range, which is associated with the speed for the gas injection into storage and the gas withdrawal from storage, we usually count the days for injection and withdrawal. For example a “170/85 days” product means 170 days’ injection and 85 days’ withdrawal.

Our usual product range is from 170/85 to 30/30. Within this range you can request all variations as shown in the matrix below.

We can offer you even higher speed than 30/30, for instance 10 days’ injection and 10 days’ withdrawal, but only if our assessment of the availability of such product results in an approval. The available volume depends on the required speed and our global storage sale. The faster product you require the more limited volume we can offer you.

We offer storage capacity down to 1 MWh.

The maximum available volume is depending on global storage sale and required speed. The faster the product is, the more limited volume we can sell. 

In addition, we offer a wide range of products with duration of 1 hour or more.

We market our capacities on fully commercial terms as an independent operator. Available storage capacity will be offered on auctions or by booking online as within-day, day-ahead or month-ahead storage capacity, first-come-first-serve. We also sell capacity on bilateral basis.

We are dedicated to provide customized storage solutions. Even we sell the capacity on auctions, we usually offer an opportunity for product customization to all successful bidders after auction close. For example, if we auction a “170/85 days” product (170 days’ injection/85 days’ withdrawal), you will have an opportunity to book additional flexibility (e.g. up to “120/60 days”) by giving us a notice within a preannounced time window after auction close. The price for extra flexibility will be published together with the Auction Rules.

Comprehensive and transparent product management is a focus point for us.

We offer capacities as a combination of seasonal capacity (170 days’ injection/85 days’ withdrawal, ie. “170/85 days” product) plus an acceleration fee in order to adopt to the exact speed requested by you (e.g. up to “30/30 days” product).

Our experience shows that this is considered very convenient and adequate by most of our customers. The additional speed (injection or withdrawal) can be added when the contract is concluded or even later, if you wish to adjust the speed of your storage capacity.

During the redevelopment of the Tyra field’s facilities, the Danish gas system will primarily be supplied with natural gas imported from Germany. The only physical connection between the Danish and the German gas systems will be the interconnection point Ellund, which can be a potential bottleneck. Therefore, filling the Danish gas storages before winter will be essential for security of supply since not enough gas can be imported from Ellund to supply Denmark and Sweden on an average winter day.

The framework for GSD's activities involves that GSD must act on commercial terms. This framework implies that the offered prices of storage services will be adjusted on a regular basis to changes in the market conditions in a way that is undisputable from a competition point of view.

During the redevelopment of the Tyra field’s facilities any available storage capacity will be offered on auctions or by booking online as within-day, day-ahead or month-ahead storage capacity, first-come-first-serve. GSD may also offer storage capacity on bilateral basis.

Please contact us for further dialogue.

You can order capacity on interruptible basis simply by submitting a nomination in excess of your booked firm capacity. GSD will consider the part of the nomination exceeding your firm capacity as a request for interruptible capacity.

Price overview

For any given hour GSD shall asses if the requested interruptible capacity is available. The assessment will be done rolling on hourly basis, last time 1 hour before the hour in question begins. After each assessment GSD shall either refuse, reduce or accept and confirm the requested interruptible capacities wholly or partly. If the total interruptible capacity requested by Storage Customers is not available, GSD shall distribute the available interruptible capacity among all nominating storage customers on pro rata basis in relation to the requested interruptible capacity.  

• There is a 1-hour lead time in every direction (injection and withdrawal) in case of re-nomination.
• Your order for interruptible capacity in a particular hour will be finally approved 1 hour before the hour in question.
• The limits for interruptible capacities (injection and withdrawal) are specified in your Storage Customer Agreement (framework agreement).

You only pay for the interruptible capacity received and utilized (pay-as-used).

You only pay the fee for the variable injection when you actually inject gas into the storage (pay-as-used). The fee for variable injection is the only fee additional to the capacity price. 

Furthermore, you have an option to replace the fee for variable injection by flat rate, which is an upfront fixed payment with free cycling.

The flat rate is an alternative to the fee for variable injection.

The flat rate is an upfront fixed payment with free cycling. The flat rate promotes multi-cycling of the storage mainly for trading purposes.

Please note:

• In case of transfer of natural gas from a storage customer with flat rate to another storage customer who has chosen to pay a fee for variable injection, we will charge the transferring storage customer (with the flat rate) an amount corresponding to the transferred amount of natural gas multiplied with the flat rate applicable at the time of the transfer.
• In case of transfer of firm volume capacity from a storage customer, who has chosen to pay a fee for variable injection to a storage customer who has chosen flat rate, we will charge the receiving storage customer (with the flat rate) an amount corresponding to the transferred amount of firm volume capacity multiplied with the flat rate applicable at the time of the transfer.

We do not charge fees for transfer, REMIT reporting, contract administration or IT. 

NO FEE POLICY APPLIES TO ALL OUR ADMINISTRATION

In case of compulsory purchasing of stored natural gas from storage customers’ accounts, Gas Storage Denmark will apply the following price:

Calculation of the Purchase Price:

1.  Monthly average of the daily quoted Dutch TTF day-ahead-prices (average of high and low quotation as published by Platts)

2.  Quotations are used for the same calendar month in which the storage gas purchase takes place

3.  Convert the price from €/MWh into €/kWh by using the conversion factor 1/1000

4.  Convert this price into DKK/kWh by using a monthly average of the daily exchange rates as published by Danmarks Nationalbank (the Danish National Bank)

We can offer you a call option for storage capacity well in advance of the service period.

The option gives you the right, but not the obligation to purchase firm storage capacity. We will reserve the capacity for you as actually booked until a predefined deadline.

You will pay a reservation fee. This is the only payment in case you do not exercise the option.

If the option is exercised your total payment will include the reservation fee and  the following payments:

• a strike price, which is the price for the firm storage capacity in €/MWh; and
• a variable injection fee that can be replaced by upfront fixed payment (flat rate) with free cycling of your storage.
