(Trondheim, 2 October 2008) Today Mayor Rita Ottervik officially opens Leirfossene power plant in Sjetnemarka,Trondheim. The new power plant will produce 193 GWh, which will cover the power consumption of approx. 10,000 households.
"In a situation where Mid-Norway has a great shortage of power and limited transmission capacity, this will contribute greatly to increasing energy production in this part of the country," says managing director Bjørn Hølaas in Trondheim Energi.
Leirfossene power plant replaces the two power plants Upper and Lower Leirfoss. The annual production with increase by 30% from 150 GWh to 193 GWh – with the same water flow.
"This is a good example that use of modern technology and solutions provide more renewable energy from existing power plants and waterways," says managing director Leif Nordseth in Trondheim Energi Kraft. Trondheim Energi is presently working on additional plans for its waterways.
The power plant is located in the mountains west of the river Nidelva, with inlet in the existing reservoir at Øvre Leirfoss. The water is led through a shaft and tunnel down to the power plant and further along a 1.5 km long outlet tunnel. Two smaller aggregates will be installed in the old power plants to utilize the required minimum flow rate of 10 m3/s in the river between them.
Construction of the power plant was started in the summer of 2006, and has cost slightly less than MNOK 400.
Trondheim Energi is part of the Statkraft group, which has a turnover of some NOK 2.4 billion and approx. 350 employees. Trondheim Energi produces, distributes and sells electric power and district heating, and has major ambitions for future development and growth.
