The Russian energy giant Gazprom is reducing the maximum gas delivery volumes through the Nord Stream 1 Baltic Sea pipeline to Germany by 40 percent.

The reason for this are delays in repair work by Siemens, the state-owned company announced on Tuesday. A gas compressor unit was not returned in time from repairs.

Therefore, only up to 100 million cubic meters of gas could be pumped through the pipeline every day – or around 60 percent of the previously planned daily volume of 167 million cubic meters of gas, it said.

The federal government currently considers the security of gas supply in Germany to be guaranteed.

A spokeswoman for the Federal Ministry of Economics said on Tuesday in response to the 40 percent reduction in gas supply. “We are monitoring the situation and examining the facts,” said the spokeswoman.

For Germany, Nord Stream 1 is the main supply pipeline with Russian gas. The Yamal-Europe line had previously not been filled.
