The massive blackout, which saw residents in Cape Town and surrounds plunged into darkness for several hours on Saturday evening, has forced the City of Cape Town to formulate a plan to mitigate risk going forward.

Several areas, including the city centre, suburbs on the Atlantic seaboard, Observatory, Paarden Eiland and Milnerton, lost power on Saturday after two high voltage power lines tripped the Tafelbaai substation. It was the second recent instance of a large-scale power outage due to an electrical fault and infrastructure damage.
