Steel group Usinor has selected Air Liquide over Electricité de France to renovate and enlarge a power plant in Dunkirk. Usinor`s steel plant is currently supplied by a 250 MW EDF-managed plant which requires refurbishment. Enron and Tractebel also made bids for the $263m (§237m) contract. Usinor said that Air Liquide`s bid was the most competitive.
