Giorgio Dodero, Chairman of the IPG Industrial Project Group Srl, is
responsible of the development of the power generation technology on
behalf of IPG. Before this IPG assignment, until 1997 Mr. Dodero has been
a senior manager of ENEL (the Italian State Owned Electric Company) and
responsible for planning and construction of large scale, multi-national,
process plants for power generation and other applications. He has
worked for more than 36 years within ENEL.
Mr. Dodero is doctor in Electrical Engineering and subsequently
participated to a course on Chemical Engineering. He has authored or
coauthored more than 70 papers and publications on behalf of ENEL
and subsequently on behalf of IPG.
