The Initiative Energien Speichern (Ines) has indicated that a particularly cold winter could lead to significant gas supply shortages in January, February, and March 2027. Current high gas prices and altered market conditions due to geopolitical tensions, such as the Iran conflict, contribute to these uncertainties. Ines reports that gas storage levels have been unusually low, with only 26% capacity filled as of May 1. Although traders have booked 76% capacity for November 1, the economic incentives for gas storage are lacking, as current market conditions favor lower prices for winter gas compared to summer.
