Scotland-based The Weir Group PLC has acquired American Hydro Corp., a manufacturer of high-efficiency turbine components for hydro-electric power generation. Based in York, Pennsylvania, 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. The acquisition is expected to accelerate American Hydro’s development in established hydro markets throughout the Americas and Europe, where there is great potential for electricity companies to economically improve renewable energy output. In conjunction with the acquisition of American Hydro, Weir is investing CDN 10million in a new service centre in Montreal to support American Hydro’s sales growth in Canada.
