The Aarberg hydropower plant is a run-of-river power plant at the beginning of the Hagneck Canal near Aarberg , which was commissioned in 1963. The plant is almost identical in construction to the Niederried-Radelfingen hydropower plant about five kilometers above the plant. The installed capacity is 15  MW and the average annual production is 86 GWh. The water of the Aare is used by two Kaplan turbines , with a gradient between 6 m and 10 m being used depending on the water level. The turbines have a total displacement of 190 m³ / s.

At the Aarberg hydropower plant, a small part of the Aare water is channeled into the old river bed, which was used by the Aare before the Jura water correction . The water serves to preserve the meadow landscape and is used by a small turbine. Depending on the season, between 3.5 m³ / s and 6 m³ / s are introduced in order to maintain a water level that varies according to nature.

The Aarberg hydropower plant is operated by BKW and is part of a system of five power plants that use the energy of the Aare water between Wohlensee and Lake Biel .
