In August 2009, an accident partly destroyed the 6.4GW power plant’s generating equipment, and six of ten huge turbine units were damaged. The GBP1.6m order is expected to be completed by late summer.

The Sayano-Shushenskaya power plant is operated by RusHydro. Work has already started on the shafts, which connect the turbine runner to the generator. Each shaft weighs approximately 100 tonnes.

Volker Schaffer, sales director of Sheffield Forgemasters Engineering, said: “Rebuilding the plant is obviously going to be a massive job but it is such an important producer of energy, particularly as a supplier to the aluminium industry, that the Russian government is keen to have it operational again as quickly as possible.

“Obviously, this lends an element of urgency to the order and we have already started work on the shafts and fully expect to complete them in good time. We are hopeful that we may be asked to provide more shafts as and when work starts on rebuilding the remaining turbine units.”
