Power Crisis: Will the Country Survive Load Shedding of Up to 32 Hours?

South Africans are bracing themselves for major power cuts as Eskom, the country’s largest electricity supplier, warns that electricity supply may be cut for up to 32 hours. The emergency measures are an attempt to prevent a total collapse of the grid at a time of high demand. If stage 16 of Eskom’s mandatory power cuts is implemented, households across the country should expect to be without electricity for up to 32 hours in a 32-hour period. The revelation comes as a voluntary association that works with Eskom is finalising a document titled “voluntary” NRS048-9 edition 3. If this document is approved, it will become a legal licence for all electricity operators in South Africa, including Eskom and municipalities, to permit power cuts beyond stage 8, which is currently the maximum permitted level.

The safety of the grid is at risk owing to mounting demand, and a total collapse of the grid is a possibility during winter. Eskom will implement the new guidelines only under these unforeseen emergency circumstances. The National Regulatory Services Association of South Africa, a collection of energy suppliers including Eskom, municipalities and regulators, is currently drafting the document.

The NRS048-9 edition 3 document requires readiness for all emergency levels as a matter of principle, but experts say it does not specify how this should be achieved. It is yet to be sent to the National Energy Regulator of SA for legal mandating consideration”. If approved, this document would permit load shedding up to stage 16. Most municipalities and Eskom-supplied areas have adopted a two-hour load-shedding schedule. On this schedule, power users should expect to be off for 32 hours in a 32-hour period (under stage 16).

A “blackout”, where the grid completely collapses, could have catastrophic consequences, so load shedding is necessary to prevent this. Vally Padayachee, Chairperson of the NRS management committee, has said that moving into advanced levels of load shedding is, though admittedly incredibly inconvenient and damaging to the economy, still the best way to prevent the grid from collapsing in this way.

Although Eskom is currently working towards reducing the number of load-shedding stages, it is imperative to prepare for a scenario in which higher measures of power reduction are needed. Currently, the document limits power suppliers from implementing cuts beyond stage 8. With mounting demand and the current behaviour of the system, an uninterrupted power supply cannot be guaranteed, and the country’s power crisis is ongoing.

The implementation of stage 16 would lead to power shortages that could impact economic activity and affect people’s livelihoods. The National Energy Regulator of South Africa, Eskom and municipalities must work quickly to ensure that the proposed measures are implemented in a controlled, systematic manner.

For South Africa, load shedding is unfortunately an ongoing feature of life. If you reside in South Africa, the following are some useful points to keep in mind:

  • Load shedding is not limited only to rural regions of the country, but also affects many major cities;
  • The load-shedding schedules of different municipalities may vary widely, so it is important to check your local municipality page for scheduled cuts;
  • During power cuts, keep refrigerators and freezers closed to keep food fresh;
  • Make sure you have access to two sources of lighting, including a battery-powered torch;
  • Ensure that all your devices, including phones and power banks, are fully charged before any power cut to minimise the amount of charging required thereafter;
  • Turn off all non-essential devices during power cuts to conserve power.

The reasons behind South Africa’s power crisis are numerous and have been a challenge to solve for many years. The main cause of load shedding is due to the ageing infrastructure of Eskom, which supplies around 95% of South Africa’s electricity to homes and businesses. Eskom’s electricity stations, which are mainly coal-powered, are under considerable strain, often requiring extensive maintenance to keep running. In addition to this problem, Eskom has faced multiple instances of state capture, corruption, and financial mismanagement, which have severely impacted the balance sheets of the company, and adversely affected South Africa’s power supply.

Despite these challenges, some bright spots are still visible on the horizon. Eskom is starting to look into more renewable energy options, including solar and wind power. As a result, the country will slowly move to rely less on coal, eventually transitioning to a more sustainable, less carbon-intensive energy source. Additionally, several communities around the country are taking back control of their electricity supply by either self-generating or moving to decentralised systems, such as community solar-powered projects.

While South Africans wait for Eskom to resolve the power situation, some are taking matters into their own hands by cutting back on their electricity usage and implementing energy-saving measures. This approach could go a long way in reducing the demand for electricity and helping to avoid widespread blackouts and power cuts.

Power outages impact all sectors of the economy, including mining, manufacturing, and agriculture. Small businesses are particularly hard hit by power cuts, which negatively impact their productivity and profits. For consumers, it leads to frustration and inconvenience. However, if Eskom, municipalities, and regulators can work together efficiently, the load shedding situation may improve, and the country can avert a total grid collapse.

Despite Eskom’s efforts to reduce load-shedding by limiting cuts to stage 6, the power crisis is far from being resolved, and the need to prepare for emergency power reduction remains as high as ever. Load shedding could impact the country’s entire economy and cause significant harm to citizens’ lives. By implementing new energy generation and management techniques, as well as encouraging energy-saving measures, Eskom can move towards a more sustainable electricity infrastructure.
