In my area we have had power cuts every alternate day which last 3 hours. The reasons Eskom gives for this is:
“Eskom meanwhile also shut a 930 megawatt unit at its Koeberg nuclear power station for three months to perform regular maintenance, reports Reuters. There are several units that had been expected to return from maintenance on Monday that are now delayed due to further technical problems,” http://www.fin24.com/Economy/Eskom-to-implement-stage-1-load-shedding-20150209
Soweto’s unpaid electricity bill totals R4 billion, and there is no sign it is going to be paid soon. This is according to a report in the Sunday Times. “Of the 80,000 Soweto households without prepaid meters, only one in six pays for the electricity it uses,” the Sunday Times reported. http://mybroadband.co.za/news/energy/117926-sowetos-unpaid-eskom-bill-r4-billion.html
TRAGIC: “Johannesburg – A Bloemfontein man, connected to two oxygen machines, died after Eskom implemented rolling blackouts twice in one day. According to the report, Engelbrecht suffered from severe asbestosis and his family believed he had not recovered from the first power cut when he died during the second one. Eskom said it was investigating the incident and would comment next week.” http://www.fin24.com/Economy/Man-dies-during-load-shedding-20150208
BUT: It’s a bit late for that now isn’t it!
Driving home during a major load shedding roll out which affected the largest part of Gauteng I passed a casino, they had power, no not supplied by a generator the traffic light was working so that grid was definitely not turned off.
PEARLS OF WISDOM FROM ESKOM: “Eskom again called on all customers to reduce the load on the electricity grid by urgently switching off geysers, air conditioners, pool pumps and all non-essential appliances throughout the day, which will reduce electricity demand. Commercial customers, particularly shopping centres and office blocks, can also make a big difference by switching off non-essential lights and not leaving office equipment such as photocopiers and computers in standby mode after hours.” http://www.fin24.com/Economy/Eskom-to-implement-stage-1-load-shedding-20150209
OK, SO HERE IS THE LOGIC: I am at work, it is 30°C and yes we do have the air conditioner on, and we have office lights turned on. Load shedding strikes unexpectedly and we have to head home eventually. So, after 3 or 4 hours the power is turned on again and all the air conditioners work through the night. Plus how many people remembered to switch off the lights …(um not many) so how much electricity did we save for that day?
