In its deliberation of 26 March 2020, the French Energy Regulatory Commission published the level of the storage component term from 1 April 2020 included in the grid access tariff. This deliberation has been adopted following the auction for storage capacities that took place in February 2020.
The storage component term is set at €78.63/MWh/d/year, a decrease of 63% compared to last year. It will be revised next year before 1 April 2021.
The storage component comes in addition to the fixed and variable grid access terms. Its purpose is to compensate for the difference between the authorised income of gas storage operators and the income received directly by these operators in the course of their activity.
It is calculated by multiplying the tariff term above and the level of winter modulation of consumption sites, the calculation of which has recently been modified. For sites T1, T2 and T3, the modulation remains defined, in MWh/d, as the difference between the normalized daily capacity and the average daily consumption of the site based on the Annual Reference Consumption. For sites T4 and TP, the new modulation is defined as the difference between the average daily consumption in winter and the average daily consumption of the site. All the sites having concluded an “interruptibility” contract will be able to lower the value of the modulation according to their subscribed interruptibility capacity.
The following sites will not have to pay this term between 1 April 2020 and 31 March 2021:
On average, the storage component is therefore expected to decrease significantly for the majority of clients. It should represent on average 0.40 €/MWh for T4 and TP sites and between 1 and 3 €/MWh for T1, T2 and T3 sites depending on their consumption profile.
