European gas prices rose on Wednesday as gas flowed eastwards for the 16th successive day along a pipeline that usually sends deliveries from Russia to Europe and political tensions remained high. The price of wholesale gas on one benchmark contract rose as much as 6 percent as the reverse flows from Germany to Poland on the Yamal-Europe pipeline continued to cause concerns, a day after European prices soared by more than 30 percent over concerns about low supplies from Russia as colder weather approaches. Russian energy exports are also in focus because of a broader standoff between Russia and the West, including over a Russian troop buildup near neighboring Ukraine, which is trying to forge closer ties with NATO. “There is growing nervousness on the European gas market again... This is chiefly due to faltering pipeline deliveries via Ukraine from Russia” Commerzbank analyst Barbara Lambrecht said in a research note. “The situation on the European gas market also remains fraught in view of the political tensions, especially as higher demand for LNG (liquefied natural gas) from Asia is feared again.” She was referring to an additional factor that is worrying traders — a warning by Indonesia that its coal supply situation is critical after it announced a ban on exports this month to avoid outages at domestic generators. Some European Union lawmakers have accused Russia, which supplies around a third of Europe’s gas, of using the crisis as leverage. They say Moscow has restricted gas flows to secure approval to start up the newly built Nord Stream 2 pipeline, which will supply gas to Germany. Russia has denied the allegations, and says the pipeline will boost gas exports and help alleviate high prices in Europe. It has said it is meeting its contractual obligations on gas deliveries. Moscow also denies US assertions that it is planning an invasion of Ukraine, which it accuses of building up forces in the east of the country. Europe has been at the heart of an energy crisis since last year, when the lifting of COVID-19 restrictions put huge demands on depleted stocks of natural gas. LOWER FLOWS The benchmark Dutch front-month wholesale gas price was up 1.75 euros on Wednesday morning at 91.25 euros per megawatt hour by 1052 GMT, having earlier traded at 95.35 euros per megawatt hour. The equivalent British front month contract was up 5 percent at 2.24 pounds per therm. The flows from Germany toward Poland however were significantly lower than the previous day. Some traders said this could indicate flows may soon return westwards but there would be a bearish impact on the market once there was definitive data showing a change in direction. Eastbound volumes fell just below 1.5 million kilowatt hours an hour on Wednesday morning down from more than 9 million KWh/h on Tuesday, latest Gascade data from the Mallnow metering point on the German-Polish border showed. “Yamal flows seem to have had some connection to abnormally colder temperatures within Russia itself in recent months, with deliveries decreasing as temperatures plummet in St. Petersburg or Moscow,” said ICIS analyst Tom Marsec-Manser. Capacity nominations for Russian gas flows from Ukraine to Slovakia via the Velke Kapusany border point, another major route, remained low on Wednesday, providing another bullish signal for prices. The nominations stood at 286,481 megawatt hours (MWh), a touch above the level from the previous day, but still well below levels seen in December, data from Slovak pipeline operator Eustream showed.
