What is Load Shedding?

Load shedding is a last resort implemented by Eskom to prevent the collapse of the national power grid. Amidst the energy crisis, it’s become necessary to provide a solution for insufficient power station capacity by redistributing power from selected areas so everyone can use electricity for at least part of the day. 

When the electrical demand is too high, load shedding prevents an imbalanced national electrical grid. It has helped to avoid a country-wide blackout that could take days or weeks to restore. 

Load shedding is different from an unscheduled power outage. Learn the differences, how the process works, and how to stay informed to prepare effectively.

What is Load Shedding?

Load shedding distributes the demand for electrical power across multiple power sources. South Africa’s national power utility, Eskom, uses routine partial shutdowns to relieve stress on the grid as a whole. Load sheds have peaked as electricity demand exceeds the existing infrastructure can supply. 

Shortages within the national electrical system unbalance the grid, which can cause the grid to collapse. The power utility rotates the electrical load in a planned manner to prevent nationwide failure, ensuring that the electrical system remains stable.

The routine lack of electricity affects every sector within South Africa. Small businesses, health care, educational, and agricultural sectors are among the industries most impacted during scheduled blackouts.

South Africa has experienced scheduled outages since 2007. The country failed to build new electrical power stations to keep up with economic growth and replace ageing electrical generation plants.

Between 1961 and 1991, Eskom completed 14 power stations with a total installed capacity of 35,804MW. Over the next 30 years, Eskom could only complete the Majuba station, which had an installed capacity of 4,110MW.

In 1998, the Department of Minerals and Energy warned Eskom and the national government that the nation would fully utilise the current generation capacity surplus by 2007. Eskom ignored this warning, and, as predicted, South Africa maxed out existing infrastructure in 2007 and began implementing load shedding.

In 2007, the power utility began the construction of the Medupi and Kusile stations, which have a combined capacity of 9,564MW. However, these stations are still not fully operational. Due to mismanagement, corruption, looting, and design faults, there have been significant delays with the Medupi and Kusile constructions.

Eskom has stated that they are addressing these challenges. However, the slow progress in completing the projects and failure to meet deadlines resulted in electrical supply issues, a constant issue for South Africans.

According to Eskom, areas affected by load-shedding shouldn’t be hit by scheduled blackouts for more than two hours. Customers can stay informed of any power and schedule interruptions in advance. 

Local municipalities also conduct load shedding to accommodate their needs and outage schedule.

What Is the Difference Between Load-Shedding and a Power Outage?

Load sheds are always pre-planned measures, usually announced early in the morning of the outage. These planned blackouts are supposed to be temporary in response to a shortage in the electrical supply, technical faults within the power stations, and insufficient coal supply and water reserves. To a lesser extent, rolling blackouts — as load-shedding is also called — can result from extreme weather events.

Power outages are not planned, which is the main distinction from load shedding. Unscheduled blackouts are almost always local municipal issues. They can occur when infrastructure and equipment failures “trip” the local municipal power grids. Other causes include illegal electrical connections, periods of poor weather, grid and network overloads, deliberate disconnections such as planned system maintenance, and cable and infrastructure theft.

How Does Load Shedding Work?

Load shedding balances the demand and supply in the nation’s electricity markets. Electricity Market operators, such as Eskom, are responsible for maintaining the grid’s reliability and safety. Eskom and other electricity market operators frequently implement load shedding when an imbalance between electricity supply and demand threatens nationwide power loss. 

Providers implement scheduled outages in stages. The duration depends on the extent of the electricity shortage, with each step requiring shedding more energy — meaning longer and more frequent blackouts. 

Load shedding stages are pre-planned measures, usually announced early in the morning of the outage. South Africans receive a warning from the power utility regarding the load-shedding stage and the time the two-hour time slot at which it will take place.

South Africans should expect to have no electricity during these two-hour time slots. In the case of higher load-shedding stages, you should plan for an additional 30 minutes of no power to help the utility restore your grid’s electricity.

With no sign of load-shedding abating anytime soon, it pays to respond proactively to scheduled grid shutdowns. You can mitigate the effects of load-shedding by purchasing an off-grid electricity source, like the DELTA Pro Solar Generator. Solar generators combine portable power stations with portable solar panels to supply off-grid power.

How Can I Stay Up to Date About Load Shedding?

The best way to check if load shedding is in place is by checking the schedule on pages for your local municipality or Eskom’s designated website page.

You can follow Eskom’s or your local area’s Twitter account to receive updates. If the power is down, visit their page and check their recent posts. If there’s no mention of load shedding on that particular day, you are experiencing a power outage.

The city will usually communicate non-Eskom-related cuts if they are related to maintenance work. However, citizens should contact their local municipalities if there is a loss of electricity related to load shedding or work in the local area.

Another great resource is the popular mobile application EskomSePush.

Frequently Asked Questions

How Long Will Load Shedding Last in South Africa?

There is no concrete answer to this question. Still, Eskom board chairperson Mpho Makwana has stated that the utility will likely implement permanent stage 2 and 3 load-shedding over the next 24 months. Other energy analysts have noted that South Africa could face scheduled power cuts until 2027 or beyond.

Final Thoughts

Using routinely scheduled power outages, Eskom has so far managed to avoid a national grid collapse. Load-shedding adversely impacts all sectors within South Africa, but you can mitigate the effects. 

The best way for South Africans to mitigate the effects of load-shedding is by investing in alternative power solutions.

The DELTA Max portable power station can power essential appliances and devices, and you can add solar panels to create an off-grid solar generator.

Or take an even bigger step toward energy independence and invest in a Smart Home Ecosystem to further reduce your dependence on an unreliable electricity grid.
