The 430 MW Gönyü power plant in Hungary, considered to be Hungary’s most eco-friendly combined cycle plant, was officially inaugurated on 27 June in the presence of state president Pál Schmitt. The plant, built by Siemens Energy for E.ON on a turnkey basis, started commercial operation on 12 May of this year. The 'most eco-friendly' tag derives from its high efficiency of over 59 percent and low nitrogen oxide emissions. It is also characterised by high operating flexibility, short startup and fast cycling capability – features that should help mitigate the effects of increased feed-in of fluctuating wind-based power.
The Gönyü combined cycle power plant is located in northwest Hungary near the city of Györ, one of the country’s most important industrial locations. In addition to turnkey erection, Siemens supplied the main components comprising an SGT5-4000F gas turbine, an SST5-5000 steam turbine, an SGEN 5-3000W generator, and the electrical and I&C equipment. The natural gas fired plant is of single-shaft design.
"Execution of the Gönyü project was also exemplary in terms of occupational health and safety. More than one million working hours were clocked up during the construction period without a single accident. During peak periods there were more than 850 workers on site,” said Rainer Hauenschild, CEO of the Energy Solutions Business Unit of Siemens Energy.
