Two years after it laid the foundation stone, Germany’s E.ON on June 27 opened Hungary’s most efficient combined cycle gas turbine (CCGT) power plant (Figure 7). The €400 million ($573 million) plant in Gönyü has a capacity of 433 MW and an efficiency of over 59%, E.ON claims. Siemens supplied the main components: an SGT5-4000F gas turbine, an SST5-5000 steam turbine, an SGEN 5-3000W generator, and the entire electrical and instrument and control equipment. The natural gas–fired power plant is of single-shaft design with the main components arranged in a single driveline.

The Gönyü plant is just one of several CCGT plants E.ON planned to put into operation this year. Others already opened since January 2011 include the Algeciras CCGT plant in southern Spain, Grain in the UK, and, more recently, Slovakia’s Malženice CCGT. Later this year, E.ON will open the Irsching 4 CCGT—a plant that features an efficiency of more than 60%—and two large plants in Russia, located in Surgutskaya and Yaivinskaya.

E.ON’s CCGT building spree is the continuation of a barrage of new installations that started three years ago. Last year, the company commissioned the Irsching 5 block in Bavaria, Germany, and since 2008, it has put online CCGT plants in Malmö in Sweden, Escatrón in Spain, Émile Huchet in France, Livorno Ferraris and Scandale in Italy, and Shaturskaya in Russia.
