Eskom will implement stage six load-shedding, or up to 10 hours of blackouts, from Tuesday morning until further notice
The demonstrations have coincided with stage 2 rotational power cuts which the state-owned utility says will remain in place until Sunday due to the breakdown of four generation units
Load-shedding will be in place from 5pm on Monday to 5am on Wednesday
Stage-four outages will continue until Friday after the loss of two units during the night, and three in total at Medupi, Kusile and Matla power plants tripping
