While load-shedding is expected to continue plaguing South Africa for at least the next six months, Council for Scientific and Industrial Research (CSIR) energy systems senior engineer Joanne Calitz has also warned consumers to expect electricity prices to increase by about another 36% by 2021.
This is drawn from a comparison over the past decade, which has seen energy prices in the country skyrocket from about 85c/kWh in 2008, to an anticipated R1.16/kWh in 2021.
This, she added, is equal to an increase of about 300% from 2008 to 2018 alone.
"These tariffs are the average Eskom tariff. As a residential customer, you would be more accustomed to the price range of around R1.50/kWh to R2/kWh. What this would mean for you by 2021, is that it will be around R2.50/kWh. This really speaks to the affordability of electricity for households going forward,” she said.
Calitz highlighted, moreover, that in just the first three months of this year, load-shedding across the country had amounted to 769 GWh. This is just over half of what load-shedding amounted to in 2015, she added.

March has been the most load-shedding-intensive month thus far, she pointed out, accounting for 595 GWh of the total 769 GWh of load-shedding.
Meanwhile, South African consumers are struggling to survive amid increased inflation, including of fuel prices and electricity tariffs, and CSIR principal engineer Dr Jarrad Wright on Thursday provided some tips to help mitigate load-shedding, while also saving on costs.
Firstly, Wright said energy efficiency would help consumers use less electricity, and in effect save on paying for it, by investing in their households.
He suggested the use of light-emitting diode (LED) lights; electric geyser blankets and/or pipe insulation; air conditioning set-point changes; and the installation of energy efficient and smart appliances for an overall reduction in electricity use.
These methods are some of the cheaper and most environment-friendly options, he explained, noting that consumers could expect to pay between R50 and R80 per LED light in the household; while consumers could expect to pay between R3 000 and R10 000 per energy efficient or smart appliance.
While the latter is more expensive, it will have the biggest impact.
The cheapest option, Wright noted, would be to adjust the air conditioning set point, which would cost the consumer nothing.
However, should consumers not have capital available in the short term, Wright suggested that consumers consider moving the use of electricity around to different times of the day. This would, in turn, assist the power system.
As an example, Wright highlighted the use of a timer on an electric geyser and pool pump.
Further, simple behavioural changes, such as changing the time at which one cooks, cleans or does washing, would have a larger impact on relieving pressure on the national grid.
“By just changing simple behaviours [like these], it would significantly reduce morning and evening demand, which is when the system is the most constrained”.
Should capital be available to the consumer, another option would be for the consumer to invest in generating their own electricity, which can be achieved through standby generators, rooftop solar photovoltaic (PV) installations, inverters for batteries or a combination of all three.
