POWER: History in Romania ALSTOM has been the first company who transferred its technology in Romania for the 330 MW units in 1968. This transfer of technology allowed Romania to develop on its own its energetic sector and industry. A large number of these units ( between 10 and 330 MW) produced under license in Romania have been exported in the world contributing to the recognition of the Romanian industry
