Siemens to Buy Dutch Gas and Steam Power Plant Component Supplier

Siemens plans to acquire the Dutch sister companies NEM B.V. and Nem Energy Services B.V. (NES). The two specialists in heat recovery steam generators for combined-cycle (gas and steam) power plants. The take-over is subject to regulatory approval by the European Commission.
 
"Heat recovery steam generators are key components for our business and account for about 15 percent of the value creation in the construction of a combined-cycle power plant. This purchase enables us to expand our capacities and enhance our expertise over the long term," says Roland Fischer, CEO of the Fossil Power Generation Division within Siemens' Energy Sector.
 
In a combined-cycle power plant, the hot exhaust gases from a gas turbine are passed through a heat recovery steam generator (HRSG) to raise steam that drives a steam turbine, considerably improving the efficiency of the power plant as a whole. 
 
In 2007, Siemens had already taken over the HRSG business of Balcke Dürr Austria GmbH and went on from there to engineer and build innovative heat recovery steam generators for projects such as the world-record-holding plant Irsching 4. Thanks to the harmonized interplay between all components – including the gas turbine and heat recovery steam generator – Unit 4 of Irsching Power Station holds the world record with a certified CCPP net efficiency of 60.75 percent.Owing to their extremely versatile output control capability and short startup times, combined-cycle power plants are ideal for compensating for the natural fluctuations inherently associated with wind and solar power.
