Under the contract, Alstom will be responsible for scheduled maintenance measures as well as short notice emergency maintenance works on the steam turbines, generators, and the turbine control and measurement technology, for 12 years.

Moorburg power plant director Dr Karsten Schneiker said: "To meet our customers´ requirements as reliable partner also in the future, we are building a power plant in Moorburg with a capacity of 1,600 MW – this is almost the complete demand of the Hanseactic city.

"Our plant will also play an important role for the grid stability in Northern Germany."

The new plant, which features two blocks, is expected to be one of the largest and most modern hard-coal power plants in Europe.

The first block will be commissioned at the end of 2014.

The contract scope also include permanent on-site presence of Alstom employees in the power plant to plan maintenance work including overhauls in the long term and to embrace any measures to the plant’s requirements as well as to guarantee short response times in the event of failures.

A total of 14 frame agreements have been signed between Alstom and Vattenfall for over 10 power plants.
