Alstom has won a second order from Vattenfall Europe Generation for the main overhaul of a generator at a pumped-storage plant in Germany.
The works at the Markersbach hydropower plant in the Ore Mountains in Saxony are due to start in June next year and be completed by February 2017.
The first order received by Alstom from Vattenfall, to upgrade another synchronous generator, is scheduled for completion in the spring of 2016.
The overhaul comprises the delivery of a new stator, upgrading of poles, bearings, bearing bracket and starting motor, as well as disassembly and re-assembly, including commissioning. A contractual option covers the overhaul of the remaining four generators.
The Markersbach was commissioned in 1979 and has an output of 1050 MW. It is the second-largest pumped-storage power station in Germany and one of the largest hydropower plants of the kind in Europe.
The renewal of the synchronous generators was necessary because some machine components, such as the generator stands, had reached the end of their service life and other parts were in need of repair.
