Under the contract, Alstom will supply a 400MVA TOPAIR generator adapted for synchronous condenser operation to produce adjustable reactive power (+250 MVar/-175 MVar) as well as required auxiliary systems.
The company will also prepare the 150,000m2 site for the new transformer station and will supply three air-insulated 380kV substations, a generator transformer with an output of 300MVA and a generator power switch.
Alstom Grid Germany country sales director Axel Kossmann said: "The highly dynamic generation of reactive power will improve grid stability.
"With the increase in renewable energies we are seeing for example in Europe and the USA, we expect demand for adjustable reactive power generation to increase in the years to come, in order to provide greater stability when using intermittent power generation."
The synchronous condenser can generate adjustable reactive power to ensure grid stability for the upcoming closure of Grafenrheinfeld nuclear power plant in 2015 and the ever-increasing reliance on intermittent renewable energies.
The condenser will be deployed in the new TenneT transformer station in Bergrheinfeld West, in southeast Germany. The new project is due to complete by the end of 2015.
