Steinsfoss Power Station

History

In 1953 the construction of Steinsfoss power station was built, but they did not start the first machine before 1957. Steinsfoss was built to utilize a bigger potential in Otra. The old power station could not compare with the new one.

Steinsfoss power station consists of two stations, Steinsfoss 1. and Steinsfoss 2. And took place from 1982 to 1985.

The waters way through Steinsfoss Power Station

The water is lead from Beiehølen into the terminal, through some gates, passing the trapdoors and into the 3,5 km long tunnel which leads down to the power station.

Before the water reaches the power station it is lead through some small tunnels, which pitch suddenly down. The water flatters again and a ventilator system opens gradually, and the water can run the turbine around.

The process is now over, the water is lead out the outlet tunnel and out in the Venneslafjord

Steinsfossen

Steinsfoss-powerstation is with its two reconstructions the biggest powersupplyer to KEV (Kristiansand energycompany). The maximum performance at Steinsfoss-powerstation in one year is 109 MW. They have an average year-production of 570 GWh. That means that they can provide power to 23 000 houses per year. There falls 560 000 tons of water, when all generators are at full production, with the speed of 1,5 meter per second. There runs 240 m³ water per second through the machines when they produce the maximum capability of Steinsfoss-powerstation.
