Siemens to Build Combined Cycle Power Plant in the Netherlands

Erlangen (Germany), April 16, 2010 - Siemens Energy has received an order from the Netherlands for turnkey construction of a combined cycle power plant. Purchaser of the 435-megawatt Hemweg 9 plant is the Dutch utility Nuon, a subsidiary of Vattenfall A.B. A long-term maintenance agreement was also signed. The plant, which will attain a very high efficiency level of approximately 59 percent and offer maximized operational flexibility with low nitrogen oxide emissions, will supply ecofriendly power to more than 750,000 Dutch households. The start of commercial operation is scheduled for late 2012.

Following the power plant projects of Sloe, Rijnmond and Enecogen, this is the fourth order that Siemens has won in the Netherlands for turnkey construction of a combined cycle power plant since 2007. "This new order, which we've secured within a year after the Enecogen project, shows that combined cycle power plants will play an increasingly important role in the fleets operated by European utilities. Because they ensure load balancing with increasing wind-based feed-in and at the same time meet the more stringent environmental requirements," said Michael Suess, CEO of the Fossil Power Generation Division of Siemens Energy.

Siemens has developed power plant concepts based on F-class gas turbine technology that attain efficiency levels of over 59 percent. These plant concepts also feature fast start capability and advanced fast cycling - characteristics that are especially attractive in the liberalized power market. "We're very pleased that we've likewise convinced Nuon with our turnkey power plant solution for Hemweg," said Rainer Hauenschild, CEO of the Energy Solutions Business Unit of Siemens Energy.

The new gas-fired combined cycle plant Hemweg 9 will replace the old Hemweg 7. In addition to turnkey construction Siemens will supply the main components: an SGT5-4000F gas turbine, an SST5-5000 steam turbine, a hydrogen-cooled generator, the entire electrical equipment and an SPPA-T3000 I&C system and will perform long-term maintenance services on the Power Train, i.e. gas turbine, steam turbine and generator.

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.

The Siemens Energy Sector is the world's leading supplier of a complete spectrum of products, services and solutions for the generation, transmission and distribution of power and for the extraction, conversion and transport of oil and gas. In fiscal 2009 (ended September 30), the Energy Sector had revenues of approximately EUR25.8 billion and received new orders totaling approximately EUR30 billion and posted a profit of EUR3.3 billion. On September 30, 2009, the Energy Sector had a work force of more than 85,100. Further information is available at:
