Nelson Mandela Bay Municipality says that the Kragga Kamma, Ditchling and Malabar power lines are still off.
In an SMS message a short while ago the Municipality said repairs to the lines are ongoing but no time frames could be given for the restoration of the electricity supply.
The Metro said cable interference, theft and electricity theft continues to be a major cause of these problems at sub stations.
Around a dozen suburbs have been without power since the sub-stations tripped on Monday night.
The outages came in the wake of load-shedding over the weekend.
