Load shedding has been a reality for South Africans for more than a decade, impacting daily life, interrupting businesses, and posing challenges to economic growth. However, there are periods when load shedding is suspended, leaving the country in a surprised state, wondering why their frozen dinner makes it all the way to a finished product instead of resulting in another load shedding loss.
What causes these interruptions in the load shedding schedule? Let’s delve deeper into the factors behind the suspension of load shedding in South Africa, and also take a quick look at some energy-saving tips you can implement in your daily life.
5 Reasons Load Shedding Gets Suspended
1. Improved Power Plant Performance
Load shedding can be suspended when previously offline or underperforming power generation units recover and return to service. Power plants often face breakdowns or go offline for maintenance or due to faults. Once these issues are resolved, and the plants are back online, the need for load shedding reduces or may be entirely eliminated for some time.
2. Decreased Electricity Demand
Electricity demand fluctuates throughout the day, and usually drops during off-peak hours, typically late at night and early in the morning. During these periods, the demand for electricity can be lower than the supply, which can lead to the suspension of load shedding. This
3. Seasonal Variations in Demand
Seasonal variations significantly impact electricity consumption. For instance, demand typically decreases during the summer months due to less need for heating. These periods of decreased demand can allow Eskom to suspend load shedding.
4. Increased Renewable Energy Supply
When weather conditions are favourable for generating electricity from renewable sources, it can reduce the reliance on traditional power plants. On days with strong winds or high solar irradiation, wind farms and solar systems can generate more electricity, potentially contributing to the suspension of load shedding.
5. Emergency Power Purchases
In some cases, Eskom may decide to purchase emergency power from independent power producers (IPPs) to meet demand and avoid load shedding. However, this is typically a more expensive option, and is used as a last resort to keep the lights on.
Quick Energy Saving Tips for Load Shedding
While understanding the factors behind the suspension of load shedding is crucial, it’s equally important to know how to conserve energy to help alleviate the strain on the power grid.
1. Smart Use of Appliances
Ensure your appliances like refrigerators, washing machines, and dishwashers are full before using them to maximise energy usage. Try to use them during off-peak times when possible.
2. Switch to LED Lighting
LED lights use considerably less electricity than traditional incandescent bulbs. Plus, they last longer, which can save you money in the long run.
3. Unplug Devices
Many electronic devices and chargers use energy even when they are not in use. Unplug these devices when they’re not needed to save power.
4. Insulate Your Home
A well-insulated home retains heat in winter and keeps out heat in summer, reducing the need for heating and air conditioning.
5. Opt for Energy-Efficient Appliances
When buying new appliances, look for those with high energy efficiency ratings. They may cost more upfront but will save you money on electricity bills over time.
Conclusion
The suspension of load shedding in South Africa typically stems from a combination of improved power plant performance, decreased electricity demand, increased renewable energy supply, and in some instances, emergency power purchases. While suspensions bring temporary relief, we understand and share the frustrations of the current electricity situation with South Africans far and wide as load shedding continues to affect the economy and various communities.
