Load Shedding: How It Works, Impacts, & Ways to Deal With It

Load shedding is a mechanism designed to reduce electricity consumption to ensure power is distributed evenly. This mechanism is implemented for various reasons, but it also has consequences.

This article discusses the ins and outs of the load shedding system and its impact on the public. To learn more, read this article to the end.

What Is Load Shedding?

Load shedding is a system implemented when the primary electricity supply in a given area cannot meet demand. The mechanism involves temporarily shutting down the power supply, usually for several minutes or hours, on a scheduled basis.

The purpose of load shedding is to prevent an overload on the primary electricity supply. This system involves load management that rotates power outages to reduce energy consumption until demand can be met evenly.

As an analogy, load shedding is like carrying a heavy shopping bag in your right hand while climbing stairs to the third floor. Midway up, you might pause briefly to catch your breath and switch the bag to your left hand until your right hand has regained its strength.

Load shedding serves the same purpose to reduce the load and strain on the power grid so that demand can still be met. This practice is quite common in South Africa, India, Lebanon, Pakistan, the United States, and Australia.

Natural disasters or extreme weather, population growth and increased demand, energy crises, unreliable primary energy sources, sudden failures of energy assets, and transmission network damage caused by disasters may all lead to load shedding to meet electricity needs.

Although it may last only a few minutes or hours, load shedding can certainly impact businesses by disrupting productivity and services.

It can be said that load shedding is a last resort to ensure that electricity can be distributed across the grid. This system also protects the power grid from damage and energy supply disruptions.

How Load Shedding Works

Load shedding is strategically planned to cut off or reduce the electricity flow to specific areas or users. This system is tightly controlled to maintain a balance between demand and capacity.

This mechanism is typically negotiated with building owners. The electricity provider monitors electricity demand, and when it approaches capacity limits or exceeds supply, the provider plans temporary power cuts or rolling electrical blackouts.

Then the service provider will offer incentives to building owners who comply with the load-shedding plan. When demand decreases, the service provider can restore power.

However, load shedding can occur suddenly, resulting in a total power outage in a specific area for a relatively short period (rolling blackout).

An example of unplanned load shedding is a brownout (a substantial and temporary drop in voltage) during a surge in electricity usage.

So, is all electricity cut off during load shedding? Generally, load shedding is scheduled so that the public knows when the outage will occur and can prepare their activities for that specific day.

Furthermore, even if the voltage is reduced or the power is briefly cut off, many buildings have backup power systems or generators, allowing business operations to continue.

Thus, these buildings may still have sufficient power to keep the internet, lights, or other electrical systems running, thereby activating electronic devices.

The Impact of Load Shedding

The impact of load shedding is certainly felt directly by users, as their activities are temporarily halted during rolling blackouts. However, load shedding is often scheduled with precision so that users are prepared for it.

People can fill up on gas, withdraw cash, and shop before the blackout day because most machines in the city will not be operational on that day. Additionally, other impacts of load shedding include the following:

Decreased business productivity.
Risk of data loss when computers are shut down.
Rising energy prices due to increasingly limited capacity.
Reduced factory output.
Risk of crime due to the security system failure during a power outage.
Increased use of alternative fossil fuels, such as natural gas.
Disruption of public services and household activities.

How to Prevent and Deal with Load Shedding

Load shedding can be prevented through the following strategies:

1. Developing Advanced Infrastructure

Areas frequently affected by load shedding must invest in advanced energy infrastructure to meet electricity needs in a balanced manner. Examples of infrastructure that can be built include renewable energy power plants.

Renewable energy plants, such as solar power plants, require significant initial investment but have lower long-term operational costs than fossil-fuel plants.

Speaking of solar power plants, the Chandra Asri Group, through Krakatau Chandra Energi (KCE), supports the development of advanced energy infrastructure by providing solar panel installation services.

As #YourGrowthPartner, KCE offers four solar power system solutions, namely On-Grid Solar, On-Grid Solar with Battery Backup System, Off-Grid Solar, and Hybrid Solar.

KCE expanded into a new business in 2020 by developing a 102 kWp rooftop solar power plant pilot project. By 2025, KCE’s solar power plant capacity will have reached 11 MWp.

2. Improving Energy Efficiency

One of the reasons for load shedding is the increasing demand for electricity that is not balanced with sufficient energy capacity. Therefore, efficient energy use is essential to reduce overall demand.

In addition to preventing load shedding, you also need to know how to handle it to prepare for power outages by taking the following actions:

Always stay updated on the load shedding schedule.
Prepare batteries or backup power sources.
Ensure all essential electronic devices, such as phones and laptops, are fully charged.
Try to stay connected to the internet to monitor load-shedding updates across various areas.
Stock up on bottled water and ready-to-eat food.
Unplug cables from outlets during power outages.
Keep the refrigerator door closed during power outages.
Back up important data on your computer before a power outage occurs.
Save emergency contacts, such as police, fire department, and ambulance numbers.

That concludes the information you need to know about load shedding. Load shedding is a measure to manage electricity consumption to prevent overloading of the primary power source.

To ensure that electricity capacity can meet user demand, renewable energy power plants can be considered.
