According to the International Energy Agency, a cold winter combined with a full stop of Russian gas supplies in October 2023 can trigger another gas crisis. However, the European gas reserves are almost full, and the dependency on Russia has been lowered to just 10% (from 83% before), so even if the prices go up, they will not go as high as last time.
The average price for gas per megawatt-hour is 200 DKK today. During the energy crisis in 2022, it was 1619 DKK. Analysts predict that a potential crisis this winter will raise the price to a maximum of 745 DKK.
