Graaff Electric Lighting Works founded by David Graaff
History
The plant was the first hydro-electric plant in South Africa and first power plant in Cape Town. It was the second electric power plant in South Africa.  The city of Kimberly had power to light up its street lights in 1882. The Graaff Electrice Lighting Works power plant was commissioned by the Cape Town City Council in April 1895 after the completion of the Molteno Reservoir that was constructed to help supply potable water to the rapidly growing city.The plant was named after David de Villers-Graaff who was mayor of Cape Town from 1891 to 1892 and personally funded the construction of the power plant.  Costing £75,000 in 1895, equivalent to £8,209,000 (around ZAR143 million) in 2017. Graaff was a big proponent of the then relatively new technology of electricity, especially for public lighting.  Demand for electricity was driven by the need for street lights to help reduce crime in the city.The plant had two 150 kW generators which could be driven either by steam or water power.  Water to power the generators was supplied from the Woodhead Reservoir on Table Mountain.  For the twelve months before 30 June 1896 the plant ran for 2590 hours on water power and for 691 hours on coal fired steam power. The plant powered 775 public street lights throughout the city of Cape Town.The plant was decommissioned in 1920 and declared a national monument in 1993.
