A cogeneration plant has been handed over to the Dow chemical site located in Stade, Germany, along the Elbe river following installation and testing.
Comprising three Siemens gas turbines and one steam turbine, the 163 MW plant contributes to secure power supplies for the entire site. Besides electricity, the new cogeneration unit will also supply process steam for the production processes in the chemicals complex.
Siemens‘ scope of supply included the planning, manufacture, factory testing, delivery, installation and commissioning of three SGT-800 industrial gas turbines (pictured) as well as one SST-600 steam turbine.
Each of the three gas turbines is connected to a downstream, supplementary fired heat recovery steam generator (HRSG), which feeds steam to an existing steam turbine as well as to a new steam turbine. The HRSG is fuelled with natural gas as well as hydrogen produced in the production process.
‘For Siemens, this confirms that we’re offering the right products for a sustainable and economical energy supply,’ said Wolfgang Konrad, CEO of the company’s Distributed Generation Business.
