Hammeren kraftstasjon

Hammeren kraftstasjon is a hydroelectric power facility in the Maridalen area that channels water from Skjaersjoen downward to generate electricity. The installation makes use of a natural elevation drop of approximately 105 meters (345 feet) to produce this power.

The facility began operation around 1900 as one of Norway's early hydroelectric plants, built by Christiania Elektrizitaetsværk. It was expanded shortly after to meet growing electricity demands in the expanding city.

The station shows how this region embraced water power as a clean energy source and became part of Oslo's identity as an industrial city. You can observe how the facility sits within the natural landscape, blending industrial purpose with the surrounding valley.

The facility sits in a valley south of Oslo and can be reached by following routes through the natural landscape from the city. Wear sturdy shoes since the terrain involves forest paths and uneven ground in the surrounding valley.

This is the only hydroelectric facility within Oslo's city boundaries and ranks among Norway's oldest power plants still in operation. Its age and continuous function make it a rare example of how early Norwegians pioneered electricity generation.
