Goldisthal Pumped Storage Plant

The pumped storage plant Goldisthal is located on the upper course of the river Schwarza in Southern Thuringia. The effective storage capacity of the upper reservoir is 12 x 10⁶ m³ and is provided with a bell-mouth type intake structure. It is connected by two steel lined 820 m long pressure tunnels, of 6.2 m dia., to a cavern powerhouse, which contains four 265 MW pump-turbines. Two 275 m long tailrace tunnels, of 8.2 m dia., run to the outlet structure at the lower reservoir on the Schwarza River.
