Abstract The first deployment of Siemens’ new path-breaking 50 Hz H-class gas turbine and combined cycle technology was in Europe with the Ulrich Hartmann power station (Irsching unit #4). This plant achieved several technology milestones and holds the world record for highest efficiency, achieved with an internally fully air cooled en- gine. Besides this world record efficiency the high degree of operational flexibility in terms of fast cycling, grid support, daily start stop and load following per load dis- patch sparked the interest of the power generation community. The commercial operation started successfully on time in summer 2011. Ever since, the H-class power plants fleet has rapidly increased its footprint from Asia over Eu- rope to the United States. Especially in Florida (United States) and South Korea the first 60Hz units were sold and four of them started commercial operation in 2013. This paper will provide a detailed update on the H-class fleet experience and will mainly focus on South Korea’s first H-class unit in operation at the LNG-fuelled Bugok site of GS EPS (Electric Power and Services) Ltd. With ignition and first fire in spring 2013 Siemens H-class technology officially starts its operation in the Asian Pacific Region. The 60 Hz Dangjin 3 formerly known as Bugok 3 plant incorporates some of the most advanced features available today in combined cycle technology, producing over 415 MW on one shaft. The plant is capable of a net efficiency of over 60% (LHV basis), with very advanced steam conditions. At the same time it ha
