When Russia invaded Ukraine in March, things went from tightness of supply to impending disaster. Russia, through a complex network of pipelines, is the principal supplier of natural gas to Europe and all petroleum products to Germany. Now it has curtailed normal flows.

Berlin is already under serious pressure after Russia cut flows through Nord Stream 1, the key connector with Europe, which is currently running at just 20 per cent capacity.

"Russia needs official confirmation that this and other turbines, which require routine maintenance and repair, will not fall under the sanctions of the EU, Canada and the UK," it said.

“We are working together with Rosatom to successfully complete the implementation of the first and second stages of construction. The constructed facilities have advanced high-tech equipment,” said Ortesia Jimenez.

Brent fell 49 cents, or 0.5%, to $99.11 a barrel, WTI fell 50 cents, or 0.5%, to $93.84 a barrel.

Russia’s natural gas exports by pipeline to the European Union (EU) and the United Kingdom (UK) declined by almost 40% during the first seven months of 2022 compared with the same period in 2021 and by almost 50% compared with the previous five-year (2017–21) average,

With nearly half of German homes relying on gas for heating, the country faces potential rationing if it fails to secure sufficient reserves.

Russian oil production in July was only 310,000 b/d below prewar levels, a fall of less than 3 per cent, while total oil exports were down about 580,000 b/d, according to the IEA’s latest monthly oil report.

Brent fell $1.34, or 1.4%, to $95.31 a barrel, WTI dropped $1.25, or 1.4%, to $89.51.

Benchmark gas declined as much as 2.9%, sliding for a third session. The continent’s storage sites are 72% full, compared to the average for the previous five years of 70.1%, data from Gas Infrastructure Europe show.
