Green light for more power from Tyin

OSLO, NORWAY--(Marketwire - November 28, 2008) -


Hydro was given the green light by the Norwegian Ministry of Petroleum and Energy on Friday for a 74 GWh production increase at Tyin power station. Hydro wishes to use the water from the Holsbruvatn lake in the Tyin water system to increase production at the power station, which is located in the municipality of Årdal.

"This news is most welcome, and a good example of the opportunities inherent in utilizing hydroelectric power resources in developed areas even better," says Executive Vice President Jørgen C. Arentz Rostrup, head of Hydro's energy operations.

The plans to use water from the Holsbruvatn lake for power production at the Tyin station represent one of several projects in Hydro's program to extract more capacity from existing plants and regulated water systems. The plans mainly concern plants in Sogn and Røldal/Suldal.

"An expansion at Holsbru will be a small but important step towards the achievement of our goal in Hydro of increasing power production by 0.5-1 TWh. We will do this partly by building new power and pump stations, and partly by speeding up the replacement of turbine runners and associated equipment that will result in greater efficiency," explains Rostrup.

Hydro was awarded a licence to build the new Tyin power station in 2001, a project that was implemented and completed in 2004 to establish what is currently Hydro's most modern hydroelectric power station.

By exploiting the catchment area of the old Tyin power station even better, and with the help of new transmissions, Hydro saw that it was possible to increase power production from the same water system resources. An expansion of Holsbru will raise the total hydroelectric production from Tyin to more than 1.6 TWh.
