(ADPnews) - Jul 13, 2010 - Andritz Hydro, part of Austrian plant engineering group Andritz (WBAG:ANDR), has received an order worth some EUR 100 million (USD 126m) for the supply of three propeller turbines and generators in Canada, Andritz said today.
Alstom will design and supply three new generating units, including propeller turbines, vertical generators, static excitation systems, speed governor systems and protection and control systems.
I would also point out that the Severn Tidal Power Group, when calculating that the barrage would save eight million tons of coal, did not deduct anything for what is called 'flood pumping', which would be the use of 216 x 9-metre-diameter propeller turbines spinning in reverse at each high tide, both neaps and springs, to boost the water level in the 185 square mile basin of the barrage and the pumping in at high water of at least six minor rivers because, for one reason or another, it would be impractical to quarry lakes to contain their flow.
