Akershus Energi

The two power stations in the enterprise, Framfuste and Øyberget power stations, were completed and commissioned in 2005. Øyberget is one of the two recently built power stations in Øvre Otta. The picture shows the main entrance and the gateway to the power station.

Øvre Otta strongly dominated the news when Stortinget (the Norwegian parliament) enacted the law to develop the project in 1999. Stortinget reduced the contractors´ original plans by half, so that the development will yield an annual production of 525 GWh.

The projecting of Øvre Otta started in 1992, and the application for concession was submitted in 1996. The King in Council granted concession for the development in September 2001.

Lake Heggebotnvatnet is the main reservoir for Øyberget power station. The water level of the lake has been raised four times after constructing a dam by the outlet of the lake.

The water is diverted from Heggebotnvatnet to Øyberget power station in a new tunnel. The power station is built in the mountain near Dønsfossen waterfall. The water is led in a tunnel from the power station into the Øvre Otta river downstream from Døsfossen.

The development of Øvre Otta appears to be an environmentally friendly power project par excellence. An already existing reservoir is utilised, and both power stations are constructed near roads. The impact on nature has been limited.
