Successful hydroelectric generation in Canada

International technology Group ANDRITZ is very active in supporting the development of renewable hydropower generation projects in Canada. Andritz Hydro Canada Inc. supplies a full line of hydroelectric turbines and generators on a water-to-wire basis.

Based in Graz, Austria, the Andritz Group is a technology-centered company with global operations. The company develops high-tech production systems and industrial process solutions for various standard and highly specialized products.

The Group has approximately 23,700 employees and has 220 production and service sites worldwide. It has 4 main business areas: electromechanical equipment for hydro power stations (turbines, generators and related systems); systems and equipment for production of pulp, paper, tissue and board; presses for metal forming, and systems for processing of stainless steel, carbon steel and non-ferrous metal strip: and equipment for solid/liquid separation for municipalities and various industries and systems and equipment for production of animal feed and biomass pellets.

In the field of hydroelectric generation the ANDRITZ group is one of the market leaders in the production of a full range of turbine, generators and auxiliary systems. It has been especially successful with its Compact Hydro activity in Canada. Within the last 5 years the company has supplied 30 of its Compact turbine generating units to 11 plants in Canada.

The Northwest Stave project consists of 3 horizontal Francis type turbines at the Stave river in southern British Columbia. This project, built by an independent power producer, is typical of many small plants is British Columbia and it has important requirements for flow ramping to comply with environmental regulations. The total installed capacity is 19 MW and the small unit of 3.5 MW will take care of the low flow in Summer and Winter. The entire plant flow of 29 m3/s can be directed through two energy dissipation valves to maintain the flow and level in the stream at all time. The plant was commissioned and put in commercial operation at the end of 2013.

Andritz Hydro is the leader in Canada and worldwide for Compact Hydro generation and energy dissipation systems with more than 200 new units designed, manufactured, delivered and commissioned per year.

Beyond the Compact range, Andritz Hydro is also a global leader in large machines for utilities. In 2013, the company was successful in winning an important order for four very large 200 megawatt Kaplan turbines, and generators for the new Muskrat Falls hydroelectric power station in Newfoundland and Labrador. As a further contract for this project Andritz Hydro will be providing a complete set of spillway.
