In the letter, the agency writes, the company claims that it allegedly cannot fulfill its supply obligations due to extraordinary circumstances that are beyond its control.
According to the source, the letter refers to gas supplies via Nord Stream.
The agency does not provide official comments on this matter.
On June 9, Russian gas supplies via Nord Stream were reduced due to planned technical work.
According to Gazprom, the supply volumes were limited due to the untimely return of equipment from repair by Siemens.
