Siemens Energy has handed over the Sloecentrale combined cycle power plant located in the Dutch town of Vlissingen-Oost to the joint venture of Delta Energy, Netherlands and EDF, France. The natural-gas-fired plant has a very high efficiency level of 59 percent, maximized flexibility and low nitrogen oxide emissions. It will supply more than two million Dutch households with ecofriendly electricity.
The plant with an installed capacity of 870 megawatts (MW) attains an efficiency of 59 percent and thus has very low CO2 emissions. Thanks to the state-of-the-art burner technology used the plant’s nitrogen oxide emissions are very low at <15 ppm. The plant is designed for 250 starts per year and is capable of supplying power to the grid within a mere 30 to 40 minutes. It thus backs up the capacity provided by CO2-free wind farms. “The new power plant impressively shows how security of supply, cost-effectiveness and environmental compatibility can be harmonized,” said Michael Suess, CEO of the Fossil Power Generation Division of Siemens Energy.
Sloecentrale comprises two single-shaft plants, in which the main components are arranged on a single line of shafting. Siemens built the plant as a turnkey project and supplied the main components – two SGT5-4000F gas turbines, two SST5-5000 steam turbines, two hydrogen-cooled generators, and the entire electrical and instrumentation & control equipment. The company also signed a long-term service agreement for the main components.
High-efficiency combined cycle power plants are part of Siemens’ Environmental Portfolio. In fiscal 2009, revenue from the portfolio totaled about EUR23 billion, making Siemens the world’s largest supplier of ecofriendly technologies. In the same period, the company’s products and solutions enabled customers to reduce their CO2 emissions by 210 million tons. This amount equals the combined annual CO2 emissions of New York, Tokyo, London and Berlin.
