VEO’s strengths in the hydro power business lie in their competence as providers of reliable solutions that are possible to integrate and execute rapidly. In other words, they know what they are doing, they do it quickly and the end result stands up to scrutiny. This is due to an experize in the company and amongst the people working at the company, an expertize that dates back to the late 1980s and is based on continuously planning, designing and executing projects such as the one in Kongsvinger.
Technologically VEO offers solutions from generators to turbines, including electrification and automation systems for the complete hydro power plant. Both efficiency and availability are important to hydro power plant owners . By implementing best practice solutions VEO can guarantee a higher plant availability and improved efficiency.
Hydropower is the major energy source in Norway. VEO is providing the solutions to use this energy as efficiently and safely as possible, while implementing these changes in a safe, quick and efficient way. This has led to VEO being the fourth largest contractor for plant modernisations in the hydro power field in Norway. On a Nordic scale, VEO has to date delivered over 250 hydro plant modernisations.
500 m3/s is a normal river flow rate for the river Glomma at Kongsvinger hydro power plant. As the most there have been cases with water flow rates in the river of up to 2000 m3/s. The gates at the hydro power plant in Kongsvinger have a capacity of coping with a flow rate to 5000 m3/s. As a comparison, the average flow rate of the Niagara falls is 1843 m3/s. Note that Kongsvinger hydro power plant is situated in the south of Norway with very low elevation (10 meters). The Niagara falls have an elevation of 51 meters.
To produce as much energy as this hydro plant – 46MW and about 0,4 TWh per year – with a same size traditional coal plant, the CO2 emission for a 40MW plant would be appr 100.000 ton. Before VEO came in, this hydro plant produced 22MW with one unit. After rebuilding the plant and adding 1 unit, the output became 46MW.
