Greek construction company Metka and its joint venture partner General Electric made the lowest bid to build a power station in Romania, the Greek company said yesterday. “The GE-Metka joint venture was named the preferred bidder to build the station,” Metka said in an Athens bourse filing. “Negotiations to reach a final agreement will begin tomorrow and are expected to last three weeks.” The 50-50 joint venture was among bidders that also included Siemens, Alstom and Mitsubishi to build an 850-megawatt plant for Austrian OMV’s Petrom unit near the Romanian oil town of Ploesti. No further details can be given while negotiations are under way, Metka said. Metka, a subsidiary of Greek metals and engineering group Mytilineos, recently won a deal to build a 427-megawatt natural gas-powered plant for Greek electricity utility Public Power Corporation.
