Siemens SGT-700 gas turbine begins operation in Germany

Posted on January 30, 2014

The Erfurt municipal utility has put the extension of its Erfurt Ost combined-cycle power plant into operation in Germany. Siemens supplied an SGT-700 industrial gas turbine, an SGen5-100A generator, and was in charge of commissioning both units. The company will also be responsible for service for the major components in the coming years.

Siemens said the thermal energy generated by its 31 MW SGT-700 turbine will also be utilized for steam generation with operation of the existing steam turbine. The flexible power plant can be used for peak-load operations as well as backup for renewable energy sources, the company said. This is due to the use of a heat accumulator and the rapid start-up and shutdown times for the SGT-700, which Siemens said can provide full capacity within a mere 30 minutes after a hot start.

The new plant in Erfurt will generate around 150 GWh/yr of electricity. This expansion of the power plant will enable the municipal utility to cover nearly the entire electricity demand for Erfurt, the company said.
