Many European gas supply companies are hurting from long-term gas deals with suppliers such as Gazprom or Norway's Statoil, which link their import rates to oil prices, while supply firms have to sell gas to customers at lower retail prices linked to the freely traded spot market.
Gazprom said on 17 January that it had adjusted contracts with France's GDF Suez, its German joint venture Wingas, Slovakia's dominant gas provider SPP, Sinergie Italiane and Austria's EconGas in deals finalised in late 2011 and early 2012.
Russian natural gas producer Gazprom has yielded to requests from several European companies for easier gas supply terms as it seeks to keep its market share in face of weakening fuel demand due to economic difficulties in the region.
