“American Hydro has a particular strength in improving the efficiency of existing stations, a field in which Weir has extensive experience in the UK and Canada. Combined with American Hydro, we have the engineering depth and skills to accelerate our development in established hydro markets throughout the Americas and Europe, where there is great potential for electricity companies to improve renewable energy output in an economically attractive manner,” said Weir chief executive Keith Cochrane.
