SUEZ and Gaz de France Jointly Acquire U.K. Teesside Power Plant; Europe's Largest Combined-Cycle Gas Turbine Plant (1,875 MW)

Regulatory News: Gaz de France (Paris:GAZ) and SUEZ have together acquired a 1,875 MW CCGT power plant located in northeast England. The acquisition was concluded with Goldman Sachs and Cargill which owned 30% and 70% respectively of Teesside Power Limited. At the conclusion of the transaction, which will be submitted to the appropriate authorities for approval, SUEZ, through its subsidiary Electrabel, and Gaz de France will each own 50% of the company. In service since 1993, the Teesside unit is located at the Wilson industrial site and, with 8 natural gas-fired turbines, is currently Europe’s largest combined-cycle gas turbine plant. The Gaz de France group thus reinforces its position in the United Kingdom where it has been present in the electricity market since 1993 with a plant at Shotton, Wales, with 215 MW of installed capacity. With its 50 per cent acquisition of the Teesside plant, Gaz de France will raise its total installed electricity production capacity to 1,150 MW. In 2007 Gaz de France, through its subsidiary Gaz de France ESS, sold 10 TWh of electricity to major industrial and service sector customers in the UK, a market where it has been active since 1999. A major energy player in Europe, Gaz de France is seeking to develop synergies between its U.K. natural gas activities, where it is present throughout the entire natural gas value chain, and its electricity sector activities. For SUEZ, this acquisition offers an opportunity to utilize its skills in the field of combined-cycle gas turbines, where it is a recognized world leader, while leveraging natural gas / electricity synergies. This acquisition also enables SUEZ to expand the scope of its energy activities in the U.K. where its London subsidiary SUEZ Global LNG coordinates the SUEZ Group’s worldwide LNG activities. Through its various natural gas, energy services, and environment activities, SUEZ has been present in the United Kingdom since 1984 where in 2007 it generated EUR 1.7 billion in revenues and has over 8,000 employees.
