[INFOGRAPHIC] Understanding load shedding so you aren't left in the dark

The power utility is also scheduled to implement up to Stage 4 load shedding on Tuesday.

Stage 5 and 6 load-shedding require 5,000MW and 6,000MW to be shed from the grid respectively.

South Africa is now in Stage 4 load shedding due to a shortage in capacity which could potentially last until Wednesday.

Ramaphosa said Public Enterprises Minister Pravin Gordhan and Deputy President David Mabuza are in continuous discussions to try to resolve the Eskom crisis. Since industrial action mid-year last year - which sparked a renewed round of load-shedding - Eskom spending on diesel to supply demand had reached nearly R5-billion.

New Zealand's police chief said on Monday that they are certain there was only one attacker involved in the mass shooting in Christchurch last week.

Eskom supplies more than 90 percent of the power in Africa's most industrialised economy but has suffered repeated faults at its coal-fired power station fleet, low water levels at hydro-power plants and diesel shortages.

Eskom COO, Jan Oberholzer says the destruction to the Cahora Bassa hydroelectric system in Mozambique which has been affected by a powerful cyclone has caused Eskom to lose about 1000 MW. Gordhan told reporters. "At this point in time, we are still getting a better grasp of the technical problems and other problems that Eskom power stations are confronting".

There has also been an increase in boiler tube leaks - which are hard to fix and require the shutdown of generation units to fix, taking days to bring back online. The performance of its generation plant remains unpredictable and there has been an increase in unplanned outages - or breakdowns at its power stations - by 13 000 megawatts against a projected 8 000MW.

Three generator units are running, but with boiler tube leaks which place them at risk.
