80kVA generator delivered to a school camp in Cullinan, Gauteng

Intergro Energy recently delivered an 80kVA generator to a school camp in Cullinan, Gauteng. The camp hosts groups of learners throughout the year, and its kitchen and facilities need to run without interruption.

A power outage at a camp is not a small problem. Meals can't be prepared, lights go out and facilities stop working, all while a full group of guests is on site. The camp needed backup power they could rely on every day, not just in an emergency.

The camp's team found Intergro through Facebook. We sized the generator to their kitchen and facility loads, arranged the finance and delivered it to site, all through one company. Today their kitchen and facilities keep running, whatever happens on the grid.

Why reliable power matters for South African businesses

For most South African businesses, backup power is now a basic operating requirement. Load shedding, grid instability and unplanned outages still happen, and every hour without power costs money.

When the power goes off, businesses face:

  • Lost revenue: production stops, tills go offline and customers leave.
  • Spoiled stock: fridges, freezers and cold rooms warm up within hours.
  • Damaged equipment: power surges and fluctuations can damage machines and electronics.
  • Unhappy customers and staff: guests, learners and employees are left without lights, food or working facilities.

A correctly sized diesel generator with an automatic transfer switch takes over within seconds of an outage, so your operations carry on as normal.

Long-term generator rental vs buying vs weekly hire

For businesses that need backup power all year round, long-term rental is usually the most cost-effective option. There are three main ways to get a generator:

Weekly hire makes sense for a wedding or a once-off project. But if you hire a generator week after week, you can end up paying the value of the generator several times over and still not own it. Long-term rental gives you the same reliable power at a fixed monthly cost that is much easier to plan for.

The tax benefits of renting a generator

Renting a generator turns a large capital purchase (CapEx) into a monthly operating expense (OpEx). For most South African businesses, rental payments for equipment used to earn income can be claimed as a tax-deductible business expense.

This means:

  • Lower taxable income: the monthly rental reduces your taxable profit in the same tax year.
  • Simpler accounting: a fixed monthly amount is easier to budget and record than an asset you depreciate over several years.
  • Capital stays in the business: money you would have spent buying a generator can go into stock, staff or growth.

Every business's tax position is different, so confirm with your accountant or tax practitioner how rental payments apply to your business.

In-house rental finance: one company, one point of contact

With Intergro Group, the generator, the delivery and the rental finance are all handled by one company. You don't deal with a separate supplier, a separate bank and a separate transport company, and you don't chase three parties when you have a question.

What this means for your business:

  • No upfront capital: get the generator you need without a large purchase cost.
  • One predictable monthly amount: a single, fixed monthly rental agreement.
  • You only pay once it's on site: your monthly rental starts only once the generator has been delivered to your property.
  • Flexible at the end of the term: when your rental period ends, you can choose to extend your rental plan.
  • Fast turnaround: our finance team aims for approval within 48 hours.
  • Delivery anywhere in South Africa: from Gauteng to the Western Cape and everywhere in between.
  • Trusted brands: we supply industrial generators with Baudouin, Volvo Penta, FAW and SDEC engines, with automatic transfer switches and low-noise options.
  • 15+ years of experience: Intergro has helped businesses across South Africa with energy and finance solutions for more than 15 years.

The process is seamless and stress-free because we handle the generator, the finance and the delivery from start to finish.

Frequently asked questions about generator rental for business

Can I rent a generator long term for my business in South Africa?

Yes. Intergro Group offers long-term generator rental with in-house finance, so businesses can get a generator for a fixed monthly amount with no large upfront cost. We deliver anywhere in South Africa.

Is it better to rent or buy a generator for a business?

For businesses that need backup power every month, long-term rental is usually better for cash flow. You avoid a large capital outlay, pay one predictable monthly amount, and keep your working capital for running the business.

Is generator rental tax deductible in South Africa?

In most cases, rental payments for equipment used to earn income can be claimed as a business expense. Confirm the details for your business with your accountant or tax practitioner.

Why not just hire a generator weekly?

Weekly generator hire is designed for short-term needs like events. Over months, weekly rates add up quickly, and you can end up paying far more than a long-term rental for the same power.

What size generator does my business need?

It depends on what you need to power. A school camp kitchen and facilities, for example, ran well on an 80kVA generator, while factories and plants may need 250kVA to 400kVA or more. Intergro assesses your loads and recommends the right size.

How quickly can I get a generator?

Once your rental finance is approved (our finance team aims for 48 hours), we arrange delivery to your site anywhere in South Africa.

When do I start paying for the generator?

You only start paying the monthly rental once the generator has been delivered to your property.

Who installs and maintains the generator?

Intergro delivers the generator to your site. A qualified electrician of your choice then installs it and maintains it when needed.

What happens at the end of the rental term?

At the end of your rental period, you have the option to extend your rental plan and keep your backup power in place.
