The South Korean engineering company, eTEC E&C, has ordered a new steam turbine from Siemens Energy for the extension of the Seagull power plant in the Gunjang industrial zone in the city of Gunsan in western South Korea. eTEC E&C is constructing the plant for its subsidiary, Gunjang Energy. The Seagull plant supplies electricity for the public grid and heating for the surrounding industries.

The new facility's installed generating capacity will be 250 MW. Delivery from the Görlitz plant is scheduled for June 2015, with the facility scheduled to produce heat and electricity for the first time in the second quarter of 2016.

Building on existing success at the Seagull power plant
Siemens has already delivered an SST-600 and a SST-300 industrial steam turbine for the Seagull power plant. These two turbines have already gone into operation successfully, and a second SST-600 turbine is currently nearing completion.

The new order includes a two-cylinder steam turbine set with reheat capability, consisting of an SST-800 turbine and a double-flow SST-500 turbine, as well as an associated SGen6-100A generator. Both steam turbines will be arranged on one shaft and drive the same generator. The order is part of the Seagull power plant's fourth expansion phase to ensure a reliable power supply in the region around Gunsan. "We once again opted for Siemens since we had very good experiences in the previous projects," said Chang-Suk OH, President of Gunjang Energy Co. Ltd. "With our new power plant, we will be able to reliably provide electricity in the region around Gunsan as well as supply process steam to the industrial segment."

Power plant efficiency is key
Because South Korea must import almost all the fossil fuels it needs by sea, the efficiency of fossil fuel-fired power plants plays a major role in the country. At the same time, the demand for electricity in South Korea is growing by 3.6% per year. In addition to orders for steam turbines, the German company has received five orders in the last three years for the construction of turnkey combined cycle power plants with its newest H-Class gas turbine.
