Siemens has received an order for the turnkey construction of the Bandirma II combined-cycle (gas and steam) power plant (CCPP) in Turkey.
The purchaser is Enerjisa, a joint venture of Sabanci Holding and E.ON. Following the Samsun project, which is currently under construction, Bandirma II will be the second power plant in Turkey to be powered by an SGT5-8000H gas turbine, marking the sale of 28 of this model of gas turbine by Siemens worldwide. These gas turbines, which have proven themselves in commercial operation since 2011, have now clocked up approximately 50,000 equivalent operating hours at an availability of more than 97 percent. Upon completion in the spring of 2016, this plant will have an installed capacity of around 600 megawatts (MW) and an efficiency of over 60 percent.
The natural-gas-fired CCPP Bandirma II will be built on the southern coast of the Sea of Marmara, near the city of Bandirma in the Balikesir province. Siemens’ scope comprises not only the turnkey construction of the plant, but also the supply of the following main components: an SGT5-8000H gas turbine, a model SST5-5000 steam turbine and an SGen5-3000W water-cooled generator, along with the entire electrical system, a 400 kV high-voltage switchgear installation and the SPPA-T3000 instrumentation and control system. The scope also includes a Benson-type heat recovery steam generator manufactured by NEM and the auxiliary and ancillary systems. A long-term service contract was also concluded for the major components, the gas turbine and generator.
“We are very excited about working together with Enerjisa. As a manufacturer of turnkey installations, our customers profit from our expertise in ideally integrating mechanical, electrical and chemical processes optimally with our products in fossil-fired power plants. Therefore we can fulfill the needs of our customers at best,” declared Rainer Hauenschild, head of Gas Turbine Power Plant Solutions at Siemens Energy. “In this project, too, we will live up to our very high claim concerning quality and safety in project engineering and execution and during the construction and installation phase”, Hauenschild added.
The dynamic power plant market in Turkey calls for flexible and eco-friendly power generation facilities that are cost-efficient at the same time, so that they are right at the top in the merit order. The Bandirma II combined-cycle power plant is of single-shaft design. Such plants are highly flexible and can be run up to full power in only 30 minutes. With load ramping of gradients of up to 50 MW per minute, they also respond very quickly to fluctuations in power demand and so can help to stabilize the grid.
Highly efficient combined-cycle power plants and the associated service are part of Siemens’ Environmental Portfolio. Around 43 percent of its total revenue stems from green products and solutions. That makes Siemens one of the world’s leading providers of eco-friendly technology.
