Glingebachtalsperre, reservoir in Finnentrop, North Rhine-Westphalia, Germany

The Glingebachtalsperre, also called Glingetalsperre, is the lower basin of the Rönkhausen pumped-storage power station in Finnentrop-Rönkhausen near Plettenberg, North Rhine-Westphalia. It impounds the Glingebach stream in a 750-metre-long reservoir. The upper basin is connected to the power house at the dam by a pressure tunnel.

The dam and Rönkhausen pumped-storage facility were built in 1969 to generate electricity during peak demand and manage water flow in the region. This project became part of a water management system that has regulated river flows and energy supply in the Sauerland for decades.

The reservoir is named after the Glingebach, also called die Glinge, the stream dammed here. It is the lower basin of the Rönkhausen pumped-storage plant, operated by Elektromark Kommunales Elektrizitätswerk Mark AG, which uses it to generate peak-load electricity.

The reservoir lies in Finnentrop-Rönkhausen, near Plettenberg in North Rhine-Westphalia. The Glingebach is impounded in a 750-metre-long reservoir; the power station building stands at the dam, fed by a pressure tunnel from the upper basin. Access is via the local road network around Rönkhausen; the site is an operating power-plant facility, so keep to paths and respect barriers.

The Glingebachtalsperre is the lower basin of the Rönkhausen pumped-storage plant, which has generated peak-load electricity since 1969. Its upper reservoir is linked to the powerhouse at the dam by a pressure tunnel. By storage volume it is the smallest dam in the Siegen-Olpe region covered by the former State Environment Office Siegen.
