Physical flow to Germany through the Nord Stream 1 pipeline across the Baltic Sea stood at 29,279,682 kilowatt hours per hour (kWh/h) yesterday morning, in line with levels of over 29,000,000 kWh/h seen throughout most of the previous day, operator company information showed.

Russian gas producer Gazprom last week said capacity through the pipeline would be cut to just 40% due to the delayed return of equipment being serviced by Germany’s Siemens Energy in Canada.

The lower flow has sparked fears over European winter supply, with several countries triggering early gas supply warnings and announcing measures to curb demand for the fuel.

Italian energy company ENI’s request for gas from Gazprom yesterday was only partially confirmed.

The Nord Stream 1 pipeline will undergo regular annual maintenance from July 11 to July 21, when there is usually no flow.

Gazprom said its supply of gas to Europe through Ukraine via the Sudzha entry point was seen at 41.9 million cubic metres (mcm) yesterday versus 41.2mcm on Tuesday.

Nominations for gas flow into Slovakia from Ukraine via the Velke Kapusany border point stood at 36.7mcm per day, broadly unchanged from Tuesday, data from the Ukrainian transmission system operator showed.

Eastbound gas flow via the Yamal-Europe pipeline to Poland from Germany eased slightly, data from the Gascade pipeline operator showed.

Exit flow at the Mallnow metering point on the German border with Poland stood at 1,086,494 kWh/h yesterday morning, up from levels of around 1,890,000 kWh/h the previous day, data showed.
