Hammeren Hydroelectric Power Station

The construction of the station was completed in 1900 by Christiania Elektricitetsværk, initially with 4 generator sets, and in 1901 increased to six units. In 1927, six generators were replaced by one unit with a capacity of 5.6 MW.

Thus, the installed capacity has become 5.6 MW, and the annual output is 16 Gwh.

For energy production, the power plant uses waterfalls from Skjærsjoen to Maridalsvannet, with a total height of 105 m.
