Why Load Shedding Is an IT Problem, Not Just an Inconvenience
South African businesses have learned to live with load shedding — but living with it and protecting against it are two very different things. Eskom's power cuts do more than turn off the lights. Every unexpected shutdown puts your IT hardware, your data, and your ability to serve customers at risk.
According to industry estimates, load shedding costs the South African economy between R500 million and R1 billion per day. For small and medium businesses in Bedfordview, Germiston, and across Johannesburg, the cost is not abstract — it shows up in fried motherboards, corrupted databases, lost sales, and frustrated clients who cannot reach you during business hours.
The good news? With the right IT strategy, your business can operate through all but the most severe stages of load shedding. Here is what you need to know.
The Hidden Damage Power Cuts Do to Your IT Systems
Most business owners focus on the obvious problem — the power is off, so the computers are off. But the real damage often happens in the moments the power returns.
Power Surges Destroy Hardware
When electricity comes back after load shedding, it often arrives with a voltage spike. These surges travel through your wiring and into every connected device. A single surge can destroy a server motherboard, corrupt a NAS drive, or fry the power supply in multiple workstations simultaneously. Standard multiplug adaptors offer zero protection against this.
Sudden Shutdowns Corrupt Data
When a desktop PC or server loses power without a proper shutdown sequence, any open files — accounting records, customer databases, work-in-progress documents — risk permanent corruption. For businesses using on-premises accounting software like Pastel or Sage, one corrupted database file can mean hours of recovery work, or worse, data that cannot be recovered at all.
Networking Equipment Takes a Beating
Routers, switches, and Wi-Fi access points are not designed to be power-cycled multiple times per day. Repeated hard shutdowns degrade network hardware far faster than normal use. The result is a network that becomes increasingly unreliable — dropping connections, slowing down, and eventually failing when you need it most.
Building a Load Shedding-Resilient IT Setup
1. Invest in Proper Uninterruptible Power Supplies (UPS)
A UPS is not optional for any business in South Africa — it is essential infrastructure. Unlike a basic surge protector, a UPS provides battery backup that gives you time to save work and shut down properly when the power cuts. More importantly, a quality UPS conditions the power, filtering out the surges and voltage fluctuations that destroy equipment.
For servers and critical workstations, choose a line-interactive or online double-conversion UPS with enough capacity to run your equipment for at least 15–20 minutes. Cheap offline UPS units may protect against surges but often fail to switch fast enough to prevent a shutdown.
2. Move Critical Systems to the Cloud
This is the single most impactful step you can take. When your email, files, and line-of-business applications run in the cloud — through Microsoft 365 or hosted servers — they keep running regardless of what happens to the power in your office. Your team can continue working from laptops, tablets, or even phones with mobile data.
Cloud-based managed IT services also mean your backups, security updates, and system monitoring continue uninterrupted, even when your office is dark.
3. Automate Your Backups
If you are still relying on someone to remember to run backups, load shedding is a disaster waiting to happen. A power cut during a manual backup can corrupt both the original data and the backup. Implement automated, scheduled backups that run to both a local device and a cloud destination. Follow the 3-2-1 rule: three copies of your data, on two different media types, with one copy off-site.
4. Protect Your Network Infrastructure
Your router and fibre ONT (Optical Network Terminal) need power to work. A small dedicated UPS for your networking equipment can keep your internet connection alive through load shedding, allowing cloud-based systems to remain accessible. Combine this with a mobile data failover solution for added resilience — many business-grade routers support automatic switching to a 4G or 5G backup connection.
5. Create a Power-Down Procedure
Every business should have a written power-down checklist that staff follow when load shedding is imminent. It should cover: saving all open work, closing applications in the correct order, shutting down computers properly, and — critically — switching off equipment at the wall to prevent surge damage when power returns. Post this checklist where everyone can see it.
When to Bring in Professional Help
Most SMBs do not have an in-house IT team to design and maintain a load shedding-resilient infrastructure. That is where a managed IT provider makes the difference.
At CT Bedfordview, we help businesses across Germiston, Bedfordview, and Johannesburg build IT environments that keep working — through load shedding, surges, and whatever else Eskom throws at us. From selecting and installing the right UPS hardware to migrating your critical systems to the cloud, we handle the technical side so you can focus on running your business.
Do Not Wait for the Next Power Cut to Teach You a Lesson
Every business in South Africa will experience load shedding this year. The question is whether your IT infrastructure will survive it intact. The businesses that invest in proper power protection, cloud migration, and automated backups today are the ones that will still be serving their customers tomorrow — regardless of the Eskom schedule.
