Siemens to install efficient gas turbine technology at Turkish power plant

Press release

Siemens, the global powerhouse in electronics and electrical engineering operating in the energy, infrastructure, industry and healthcare sectors, has won the order for the supply of a single-shaft power island with the company’s record-breaking H-Class gas turbine technology, for the Samsun Cengiz Enerji combined-cycle power plant in Turkey.

The customer is Cengiz Enerji Sanayi ve Ticaret A.S., an independent power production (IPP) company, which will build and also operate the plant. With the SGT5-8000H as its core component, the plant will feature an installed capacity of approximately 600 megawatts (MW) and an efficiency of almost 61 per cent. This will make Cengiz’s Plant in Samsun the most efficient fossil-fired power plant in Turkey. Commissioning is scheduled for the start of 2015. The total order volume, which includes a long-term service contract, will be almost EUR300 million.

Cengiz Enerji's Samsun combined-cycle power plant is located east of Samsun, the largest city in the Black Sea Region of Turkey, and operates on natural gas. The Siemens scope of supply comprises a power island which includes an SGT5-8000H gas turbine, an SST5-5000 steam turbine and a SGen5-3000W generator. Siemens will also supply a Benson heat recovery steam generator, the electrical system, the SPPA-T3000 control system, and auxiliary and ancillary systems.

In addition, Siemens has signed a long-term service contract for the equipment, which will help reduce emissions and ensure reliability and availability of the plant. The power plant will be configured as a single-shaft plant. Plants of this kind are very flexible and are designed for 250 starts per year. They are capable of producing full load in as little as 30 minutes after six hours shutdown. Furthermore, they react very quickly to grid fluctuations and can adapt their output by more than 35 MW within one minute to meet the changing power requirements.

The Turkish power plant market is developing dynamically and is subject to stiff competition. It requires flexible, environmentally benign power generation plants which can feature high in the merit order ranking. 'Our new plant in Samsun will meet Cengiz Enerji’s requirements for a flexible power plant with short startup times and fast load capability and will be the perfect complement to our power plant fleet', says Ömer Mafa, CEO of Cengiz Enerji.

'Cengiz Enerji’s new and very flexible plant will be very successful on the electricity market. We are happy to join forces with Cengiz to execute the most efficient power plant project in Turkey,' said Peter Gisbert, Director, Gas Turbine Power Plant Solutions in the Fossil Power Generation Division at Siemens Energy.

High efficiency combined cycle power plants are part of Siemens’ Environmental Portfolio. In fiscal 2012, Siemens generated revenue of EUR33.2 billion from the portfolio, a growth of 10 percent compared to the previous year and amounting to 42 percent of total revenue. During the same year, Siemens’ customers reduced carbon dioxide (CO2) emissions by 332 mega tonnes, an amount equal the total annual carbon dioxide emissions of Berlin, Hong Kong, London, New York City, Tokyo, Moscow, Jakarta, São Paulo and Melbourne.
