Steenbras Power Station

The Steenbras Power Station, also Steenbras Hydro Pump Station, is a 180 MW pumped-storage hydroelectric power station commissioned in 1979 in South Africa. The power station sits between the Steenbras Upper Dam and a small lower reservoir on the mountainside below. It acts as an energy storage system, by storing water in the upper reservoir during off-peak hours and releasing that water to generate electricity during peak hours. The City of Cape Town uses the power station for load balancing and to mitigate against loadshedding caused by the South African energy crisis. This power station is reported to be the first pumped-storage hydroelectric power station to be built on the African continent.
