Ever heard of “wasted” electricity? That’s what a poor Power Factor can cause. Improving it can unlock significant savings and efficiency gains for your business. The excess current caused by a poor power factor generates extra heat in your electrical systems. This thermal stress can damage and shorten the lifespan of critical and expensive equipment like motors, transformers, and switchgear.

You could be paying for electricity you’re not even using!

A low power factor means your electrical system is drawing more current than it needs to do the actual work. Eskom often penalize businesses for this inefficiency with higher demand charges on their electricity bills. Fact is, correcting your power factor can directly reduce you costs, leading to immediate and substantial monthly savings. An energy audit pinpoints exactly how much you could save.

A poor power factor reduces your building’s electrical capacity

Think of it like a clogged pipe. Inefficient current flow from a low power factor “clogs” your electrical system, meaning your transformers and cables can’t handle their full potential load. The fact is, by implementing power factor correction, you can “unclog” the system, freeing up capacity.

The fact is, by implementing power factor correction, you can “unclog” the system, freeing up capacity. This can help you avoid or postpone expensive infrastructure upgrades when adding new equipment.

Is your power factor costing you? Don’t guess, let’s measure! Our energy audit(R5000 incl vat) includes a detailed power factor analysis. We’ll identify inefficiencies and help you take steps to fix them.

When Meadowdale was hit by prolonged outages this past month, many businesses had to make use of expensive alternative power sources like diesel generators, one of the business owners spent close to R60 000 on fuel during the eight days of the outage to keep the power on. Others had no choice but to shut their doors.

Bigfisch Projects, felt the impact too, with our offices are in Meadowdale, not because our operations stopped, as we have solar installed on our property, but because of the impact in our community, partners, and clients that were left without electricity for days,

This wasn’t load shedding. It was an unexpected crisis caused by a veld fire on the 23rd of August and damaged infrastructure.

It highlights something we’ve long known, in South Africa, outages come from more than just Eskom’s schedules. They’re unpredictable, disruptive, and increasingly costly.

Too often, businesses plan only around Stage 4, 6, or even 8 load shedding. But what happens when the power is gone for a week because of a damaged power supply lines or substation failure? No schedule. No SMS warning. Just instant darkness.

For any business, downtime isn’t just an inconvenience, it’s catastrophic, with lost revenue, possibly damaged stock, halted operations, unproductive staff to be paid, or sent home which impacts their livelihood, missed orders and broken client trust, the list gets long.

How did we keep doors open?

At Bigfisch Projects over the years we have partnered with numerous clients from various industries from Commercial to Industrial, Mining and Agriculture in Southern Africa and have developed tailored energy solutions that fit their requirements and budget.

With access to funding to unlock cash strapped projects many more of these businesses have been able to maintain consistency in their operations without negatively impacting their cashflow.

Our services include Load Profiling & Reporting to determine specific needs, solution-based Project Development & Engineering, supported by Financing if required.

Once approved we start Procurement & take care of Product Supply and Project Management, and ongoing Solar Plant Operation & Maintenance after system commissioning and final handover.

We offer diverse solutions ranging from Rooftop or Ground Mounted Solar and even specialised structures such as Car Parks. These systems can be a combination of a Grid Connected application with diesel Generator Integration, a Containerized – Battery Energy Storage System or fully fledged Integrated Smart Micro Grid.

The recent electricity supply interruption on our doorstep has reinforced the lesson we share with clients every day: Backup power is a necessity for every business not a luxury.

If your company is still relying on municipal supply capability alone, you’re taking on unnecessary risk. Here’s how businesses can prepare for outages scheduled or not:

Backups That Last: Solar and battery systems that carry you through hours, days, or even weeks.

Know Your Load Profile: Energy audits that size systems correctly and prevent overspending.

Critical Load Prioritisation: Keep essential equipment on, cut what doesn’t matter, and extend your runtime.

Integrated Systems: For many businesses, it’s not just electricity, it’s cooling, water, or production too. A holistic system keeps the essentials going.

Ongoing Optimisation: Monitoring and adjustments ensure your system continues to match your business needs.

We witnessed Meadowdale businesses struggle because of an outage no one planned for. We also saw how the right solutions make the difference between shutting down and remaining operational, some businesses that already have alternative energy solutions in place managed to carry on without skipping a beat. We salute you!

Bigfisch, doesn’t just sell solar panels. We design and build on-site resilience that form part of dynamic energy solutions. Because in Africa today, it’s not only about whether it’s a power outage due to supply interruption, but aging and failing infrastructure, vandalism, theft and many more factors are be considered as well.

Let’s talk about how your business can safeguard against the next outage.

Load shedding continues to affect businesses and homeowners, leading to substantial financial losses and operational disruptions. A typical business reports a loss of about R25,000 over three months due to power outages, equating to roughly R8,000 per month. This burden on businesses translates into slower growth, reduced profitability, and potential job cuts, impacting the broader economy.

Disruptive Effects on Business and Homeowners

Load shedding doesn’t just cause financial losses; it disrupts everyday activities for both businesses and homeowners. A recent survey revealed that nearly 97% of businesses found load shedding to be significantly or moderately disruptive to their operations. For homeowners, 91% reported that load shedding had a high or moderate impact on their daily routines.

Solar Energy: A Solution to Load Shedding

To mitigate the effects of load shedding, many are turning to solar energy. Solar energy systems can provide a reliable source of power during outages while also reducing electricity costs. A typical business with an estimated annual electricity consumption of 145,000 kWh can benefit from a 71.04 kW solar system, which can help maintain operations during power interruptions.

Cost-Effective Solar Panel System

Investing in a 71.04 kW solar system can be a cost-effective solution to load shedding. Here’s a typical setup:

  • Solar Panels: 128 Jinko Solar panels, each with 555 Watts, totaling 71.040 kW of solar power.
  • Inverter: 1 SOLIS inverter with a 50 kW rating.
  • Battery Storage: 1 Greenrich battery providing 9.46 kWh of storage.

This solar system can generate approximately 100,450 kWh per year, reducing reliance on the grid and lowering electricity costs.

Financial Benefits of Solar Energy

Beyond providing a reliable source of power during load shedding, solar energy can lead to significant cost savings. With a 71.04 kW system, annual utility bill savings could reach R4,356,802. Considering a net system cost of R850,000, the potential net savings amount to R3,506,802. This makes solar energy a smart investment for both businesses and homeowners.

Strategies for Reducing Energy Usage

In addition to solar energy, there are other ways to reduce electricity costs and minimize the impact of load shedding. Here are some effective strategies:

  • Switch to LED Lighting: LED bulbs consume less energy, with a typical bulb using only 10 watts.
  • Use Energy-Efficient Appliances: Opt for energy-efficient appliances. For instance, air conditioners can use up to 1.8 kWh per hour, while ceiling fans use only 0.6 kWh.
  • Install Energy Management Systems: These systems can help monitor and control energy usage, reducing overall consumption and costs.

Conclusion: Solar Energy and Beyond

Load shedding poses significant challenges, but solar energy offers a sustainable and cost-effective solution. By investing in solar energy systems, businesses and homeowners can not only reduce their electricity bills but also maintain a reliable source of power during outages. Along with energy-saving practices, these solutions contribute to a more sustainable and resilient energy future.

South African businesses are once again grappling with the dual challenges of escalating electricity costs and the resurgence of load shedding. The National Energy Regulator of South Africa (NERSA) has approved a 12.7% tariff increase for Eskom, effective from April 1, 2025. This hike, coupled with the return of scheduled power cuts after a 10-month hiatus, poses significant operational and financial challenges for enterprises across the country.

Breaking Down the 12.7% Increase: Implications for South African Businesses

The approved 12.7% tariff increase, while lower than Eskom’s initial request of 36%, still substantially exceeds the national inflation rate. For businesses, this translates to a considerable rise in operational expenses. For instance, a company currently paying R100,000 monthly for electricity will now incur an additional R12,700 per month, amounting to R152,400 annually. Such increases can erode profit margins, necessitating price adjustments that may affect competitiveness.

And then there was darkness…

The reintroduction of load shedding exacerbates the situation. Beyond the immediate inconvenience, power outages have profound economic repercussions:

  • Lost Revenue is sadly the reality for many small businesses.Interruptions halt production and services, leading to missed sales opportunities. It’s estimated that load shedding can cost South Africa over R4 billion daily, a significant portion of which impacts small and medium-sized enterprises.
  • Productivity Declines: Frequent power cuts disrupt workflows, causing delays and reducing overall efficiency. Businesses often struggle to meet deadlines, leading to potential reputational damage.
  • Equipment Damage: The inconsistent power supply can result in electrical surges, damaging sensitive equipment. The cost of repairs or replacements adds to the financial strain.

It’s not just about Solar Panels

While adopting solar power is a positive step towards energy independence, relying solely on solar installations without integrated storage solutions may not fully address the challenges posed by load shedding and rising tariffs. A holistic approach includes:

  • Battery Energy Storage Systems (BESS): These systems store excess energy generated during peak production times, ensuring a reliable power supply during outages and at night.
  • Hybrid Systems: Combining solar power with traditional energy sources and storage solutions provides flexibility and ensures uninterrupted operations.
