Drax closes in on major turbine modernisation

Drax Power Station is a month away from completing what it claims is the largest steam turbine modernisation programme in UK history in an attempt to increase the coal-fired power station’s efficiency.

The five year project, costing £100M, will reduce the plant’s CO2 emissions by 1M.t a year, equivalent to taking 275,000 cars off the road. The increased overall efficiency of almost 40% will also improve reliability and availability in generation output, delivering greater value to the business.

Siemens AG (”Siemens”) was awarded the £100M contract to modernise all six units at the power station in 2007. Over the subsequent five year period, together Drax and Siemens have replaced the low pressure and high pressure turbines on all six units at the power station.

The new turbines, manufactured by Siemens Germany, consist of 28 separate turbine rotors weighing over 2,800t, and over 80,000 individualised turbine blades, which, laid end-to-end would stretch the distance of the London marathon.
