Goal and impact
The algorithm aims to annually set the discount on interruptible capacity at GTS (Gasunie Transport Services) in the 'Gas Tariff Code'. This discount is applied to the regular tariffs for transport capacity and is a compensation on contracted interruptible capacity for the fact that GTS is allowed to interrupt gas transport under such a contract when there is not enough capacity in the network for the contracted capacity.
Considerations
The advantage of this algorithm is that it gives the ability to analyse a lot of data in a short time to reach a good decision. Using the algorithm shortens the time needed to determine the discount rate.
Human intervention
The outcome of the algorithm is carefully and manually checked before the decision is published.
Risk management
The model is tested for correct operation before use and outcomes are manually checked before publishing the discount rate.
Legal basis
Grid code on harmonised transmission tariff structures for gas, based on EU Regulation 2017/460 (Article 16)
Operations
Data
Shutdown data for the past 3 years combined with average duration of shutdown and total shutdown capacity
Technical design
The discount for interruptible capacity is calculated based on the calculation article 16 NC TAR. The number of disconnections over the past 3 years is multiplied by the average duration of the disconnection and the total disconnected capacity. We divide this total by the total booked interruptible capacity. We call the result "pro". The ACM uses an adjustment factor of 1, making the final discount rate equal to "pro", rounded to two decimal places.
