Siemens Receives Order for Largest Turbine-Generator Set Produced to Date in Gorlitz
Erlangen, Germany, 2010-06-07 - Siemens Energy has received an order for the largest three-cylinder steam turbinegenerator produced to date within the Industrial Power Business Unit. This condensing steam turbine-generator will in the future supply the Latvian capital Riga with district heat and electrical energy in the Riga TPP-2 Combined Cycle Co-Generating Facility (Riga TPP-2 Reconstruction Project Second Unit).
The turnkey contract has been awarded to the Turkish EPC (Engineering, Procurement, Construction) company Gama Power Systems Inc., which will design, supply, erect, and commission the cogeneration district heating plant in Riga for the Latvian utility Latvenergo A.S.
The new cogeneration district heating plant will have an overall electrical capacity of approximately 420 megawatt (MW) and a thermal capacity of as much as 270 MW. The Siemens condensing turbine-generator will feature three industrial steam turbines, two SST-800 machines and one SST-500 steam turbine, which will be produced at the company's manufacturing plant in Gorlitz. The order also includes a generator, a condensing plant, and three district heat exchangers. With a train length measuring approximately 36 meters the turbine-generator will be the largest district heating plant built to date in Gorlitz. In summer, the turbine-generator unit will provide an electrical output of 145 MW, and in winter a thermal output of 249 MW combined with an electricaloutput of 125 MW. The steam turbine-generator ordered from Siemens is also unique in terms of its complexity and flexibility. The turbine configuration and the use of in total three district heaters allow a precise adjustment of the turbine generator performance to the actual heating demand. During the summer months or during periods with low heating demand the third SST-500 steam turbine in the train can be shut down.
"For the first time, our engineering team has combined field-proven technology in a new design," said Markus Tacke, CEO of the Industrial Power Business Unit of Siemens Energy. "To date, only two-cylinder industrial steam turbines have been supplied - and now we're producing a train comprising three steam turbines. I'm pleased that with this order we're demonstrating to our customer the innovational capabilities of our company and at the same time securing its faith in our flexible product solutions, which precisely meet its needs."
