A significant drop in the filling level in German gas storage facilities to less than 90 percent, which was temporarily recorded on the website of Europe's gas infrastructure operator (GIE) at the weekend, turned out to be a reporting error. The association corrected the error on Sunday. The filling level of the German gas storage facilities was then again given as 95.28 percent.

The cause of the glitch was apparently an error in data transmission. The filling quantity of the Uniper Epe H-Gas storage facility was not taken into account when calculating the total filling level due to a transmission error, said a Uniper spokesman for the German Press Agency. According to the Uniper overview, the memory is 97 percent full. However, its filling level was shown as 0 percent in the GIE table on Saturday and also on Sunday morning. Uniper said it was still investigating how the transmission error could have occurred.

Habeck: "Important milestone"

The consequence of the reporting error: On Saturday, the GIE website showed a filling level of only 89.56 percent for the German gas storage facilities, and only a little more on Sunday morning. As recently as Friday, the website had reported a fill level of 95.14 percent. Federal Minister of Economics Robert Habeck (Greens) described reaching the 95 percent mark as an "important milestone".

A spokesman for the Federal Network Agency had already given the all-clear on Saturday morning. "We consider this to be a data transmission error," he said. Due to the warm weather, no gas is currently being withdrawn.
