Trusted Partner

For us, reliability means living up to what we promise

Highest standard Long maintenance intervals Forced Cooling regarding maintenance Reduced outage time and Reduced outage time intervals costs Major overhaul (open casing) after 100,000 EOHs, ~12 years Majority of customers have no findings at major overhauls

Strict quality control Benchmark defining Flexible start-up modes Highest requirement on tolerances reliability Fast/Normal/Slow Reduced spare parts need 1.8% higher reliability Optimized EOH consumption Reduced forced outage rate compared to NERC1) statistics 2007-20112)

For us, flexibility means fulfilling your requirements

Hot start “on the fly” Bypass cooling Hot start “on the fly” HoF+ Fast thermal Reduction of hot start-up loading capability Reduction of hot start time of up to ~30 minutes time without additional investment Barrel type HP turbine Fast Cycling FACY Fast thermal Faster ramp up Integrated boiler loading capability partner concept to ensure fast plant ramp- up Founded boiler expertise Flexible start-up as licensor of Benson modes fast/normal/slow Real time EOH consumption monitoring boiler technology Optimized start-up time based on Reduction of start-up EOH consumption demand Remaining EOHs  faster start-up

For us, efficiency means the optimum for your RoI

World Class in Clean Coal

Since start-up in 2008, Waigaoqiao III has, compared Com. operation: 2008 to an average Chinese coal-fired power plant, saved Power output: 2x 1,000 MW 1.1 million metric tons of coal and reduced CO2 output by 2.8 million metric tons annually. Efficiency: 45.03 % The plant reaches an efficiency (net) of up to 45 %, Main steam: 270 bar / 3,916 psi making it one of the most efficient coal power plants 600 ºC / 1,110 ºF in the world. Reheat steam: 600 ºC / 1,110 ºF

Up to 1 million tons less CO2 emissions

The Lünen plant can provide electricity for around 1.5 Com. operation: 2013 million households and supplies the city of Lünen with Power output: 750 MW district heating. With an efficiency of almost 46 %, Lünen is the cleanest and most efficient hard-coal- Efficiency: 46 % fired power plant in Europe. Using leading-edge Main steam: 270 bar / 3,916 psi Siemens-technology makes it possible to save up to 600 ºC / 1,110 ºF
