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.
