The goal is to prevent storage levels from falling so far that governments must ration gas to businesses. Gas storage must remain above 33% for a secure winter, according to the IEA, while levels below that risk shortages if there's a late cold snap.
Lower levels also would make it harder for Europe to refill storage next summer, while higher reserves from conservation would help lower extremely high prices.
European leaders say the cutback in Russian gas is energy blackmail aimed at pressuring governments over their support for Ukraine and sanctions against Moscow.
Since Russia halted flows this month through the Nord Stream 1 pipeline running under the Baltic Sea to Germany, it and the parallel Nord Stream 2 — built but never operated after Germany refused to certify it — were damaged in underwater explosions that European governments say are sabotage.
Demand for liquefied gas has driven up prices and tightened supply to the extent that poorer countries in Asia cannot afford it. Bangladesh is experiencing widespread power blackouts, while Pakistan faces rolling blackouts and has introduced reduced working hours for shops and factories to save electricity.
“Interregional competition in LNG procurement may create further tension, as additional European needs would put more pressure on other buyers, especially in Asia, and conversely cold spells in Northeast Asia could limit Europe's access to LNG,” the agency said.
The gas crisis in Europe has also deprived Asian countries of the limited number of floating regasification terminals, which were expected to play a major role in LNG imports in Southeast Asia. Europe has secured 12 of the vessels and plans another nine.
