Load shedding was implemented on Tuesday across South Africa due to a shortage of generation capacity as several power units in the national electricity utility Eskom are currently out of service due to planned and unplanned outages. Eskom
The rolling blackouts started from 4 p.m. and is likely to continue until 10 p.m., the Eskom said.
“Any additional changes on the already vulnerable and constrained power system could lead to a change in the stage at short notice,” Eskom said.
“Eskom would like to assure customers that load shedding is a necessary measure to protect the power system,” the parastatal said.
It was the first rolling blackout since the end of Easter holiday.
Eskom has three stages for load shedding aimed at avoiding a total collapse of the power system. Stage one allows for up to 1000MW of the national load to be shed once a day. If the pressure grows, stage two for up to 2000MW or stage three for up to 4000MW would be shed. At stage two, power goes off twice a day, while at stage three, electricity could be cut two or three times a day.
Eskom called on all customers to reduce the load on the electricity grid by urgently switching off geysers, air conditioners, pool pumps and all nonessential appliances throughout the day, which will reduce the severity of load shedding.
Commercial customers, particularly shopping centers and office blocks, can also make a big difference by switching off nonessential lights and not leaving office equipment such as photocopiers and computers in standby mode after hours, the utility said.
South Africa has suffered from power insufficiency since 2008. Power cuts, which have cost the economy billions of rand since 2008, have again become common since November last year when two coal-burning major power stations broke down. Enditem
