The power plant, which was built in 1900–1903, is located on the Säveån River and is in operation.
It has four generators (aggregates) that together can produce up to 1,900 kW of electricity. In one year, the power plant generates 8 GWh of electricity, which is enough to supply approximately 2000 three-room apartments with renewable electricity.
In 2006, the power plant was modernized with new control equipment and a 10 kV high-voltage switchgear was installed to improve electricity production.
The building has been designated as Sweden's most beautiful granite power plant building by the National Heritage Board! We are very proud of that at Partille Energi!

Hydropower plants generate electricity by using the kinetic energy of flowing water. To control electricity production, larger watercourses are dammed, which converts the water's kinetic energy into potential energy.
By regulating the dam gates, the potential energy in the water is converted back into kinetic energy and drives the turbines.
The water used in our hydroelectric power plant comes from Lake Aspen via the Säveån River. At a dam on the southern part of the lake, the water is divided into two flows. One that flows freely past Jonsered and a flow that is led into the power plant and converted into electricity, before being led out downstream of the power plant. A salmon ladder allows fish to get upstream past the power plant in the power plant flow and in the other flow the fish can swim freely. At the dam there is an eel migration network where eel fry can get upstream.
Skånska Cementgjuteriet built the power plant and the architect was Hans Hedlund. It was visited during construction in 1901 by King Oscar II. The king visited Jonsered on September 14, 1901 and wrote his name on the rock where the power plant canal begins.
Hans Hedlund was greatly inspired by the American architect Henry Hobson Richardson and the power station is an example of this: massive brick walls, rough-hewn natural stone and round-arched portals and windows. The County Administrative Board of Västra Götaland's description of the cultural-historical value: "Jonsered's power station has a very high cultural-historical value and the power station is in listed building class."
