In response to the unfavorable market conditions, Uniper Energy Storage is offering a faster product for the Breitbrunn storage facility for the remainder of the 2025/2026 storage year in order to enable the market to fill a partial capacity. This means that all currently available injection and withdrawal capacity will be allocated to the new product.
Uniper Energy Storage still has a free working gas capacity of 6.2 TWh in the Breitbrunn storage facility for the current storage year 2025/26, which could not be marketed due to permanently unfavorable market conditions. Even at the last auction on May 7, 2025, there was no significant demand despite the recent increase in the summer-winter spread. On May 22, 2025, the so-called critical filling path started for the firm unsold share, from which a continuous storage injection would have been necessary in order to secure the filling level target for Breitbrunn. The new filling level target for the Breitbrunn storage facility, which came into force on May 6, 2025, by way of an ordinance (GasSpFüllstV) of the Federal Ministry for Economic Affairs and Energy (BMWE), is set to be 80% on 1 November. In view of the physical injection capacity for 2025, this target can no longer be achieved with certainty. Uniper Energy Storage has offered this capacity in due time for booking and filling to market area manager Trading Hub Europe GmbH (THE). So far, however, no measures have been taken in accordance with Section 35 c (2) of the EnWG.
In order to attract greater market interest, Uniper Energy Storage has reacted and will offer a faster product for the Breitbrunn storage facility for the remainder of the 2025/26 storage year. With this faster product at least one third (2 TWh) of the remaining free capacity can be used economically and thus this partial capacity can be filled by the market. The new storage product will offer storage customers the option of filling a storage bundle (AGV, AL, BL) in 55 days and withdrawing it in 120 days. Consequently, all currently available injection and withdrawal capacity will be allocated to the new product.
