Technology Type Open-loop Pumped Hydro Storage
Rated Power 400000 kW
URL More about Palmiet Pumped Storage Scheme
The scheme has a dual role: - to generate electricity for the Eskom National Grid during peak and emergency demand periods - to transfer much needed water from the Palmiet River to Cape Town. Water is stored in an upper and lower reservoir. For power generating purposes, water flows from the upper reservoir to the lower reservoir via two reversible pump/turbines. During off peak periods the water collected in the lower reservoir is pumped back again. During winter rainfall months, excess water in the Palmiet River is pumped to the upper reservoir for transfer to the Steenbras Dam and the Cape Town water consumer.
