Backup generators: we don’t really think about them until load shedding kicks in. When we are using them, few of us give thought to how much fuel they are using to keep our lights and plug points working. With petrol and diesel prices skyrocketing in South Africa, it’s good to know that there are ways to save money on your generator’s fuel. This article is taking a look at what affects a backup generator’s fuel consumption:
Type of generator
The type of generator you have will influence its fuel consumption, since generators come in many sizes and output capacities. Smaller, portable generators used only to power certain appliances and devices use considerably less fuel per hour than larger generators powering whole buildings or groups of buildings. Newer generators feature more modern technology than older ones. Modern generators are built to be fuel efficient, so if your generator is ancient, it will likely consume more fuel than a new generator.
Backup generators also run on a variety of fuels. Some generators are multi fuel, meaning they can operate on two or more types of fuel. When it comes to fuel consumption, we could argue that the generator which burns through fuel the slowest is more fuel efficient. Diesel burns slower than any other fuel type, making diesel generators some of the most efficient you’ll find. Natural gas generators, in contrast, burn fuel at much faster rates than diesel, which renders them less fuel efficient.
The final consideration when looking at what affects a backup generator’s fuel consumption is load. This refers to the number of appliances, devices, and other electricity-requiring things a generator needs to power when in operation. Generators that struggle to power what they need to will burn through their fuel tanks much faster than others. When a generator can comfortably handle its load without having to be pushed to its limits, it won’t be as thirsty for fuel.

Load shedding, while easily managed when a business has a generator, can often cause major issues for South African businesses. Although, merely having a generator doesn’t mean a company’s load shedding woes are solved. We’ve seen many instances where a generator has been run for hours on end unsupervised, only to end up running out of fuel and becoming severely damaged. Refilling a generator before the fuel tank runs out is very important, which is why we are often called out to refill our clients’ generators. On 13 November 2019 we were called out to a client in Escourt who urgently needed a diesel generator refilling. Find out more about this project below:
Due to long spells of load shedding occurring regularly in Escourt, KwaZulu-Natal, our client was running their generator almost throughout the day, every day. What other option do you have as a business owner when the lights go out? Due to the long periods of operation, the generator’s diesel tank quickly depleted. Since larger generators have very big fuel tanks, it’s difficult for business owners to source the amount of diesel needed to fill them. That’s where diesel generator specialists like us come in.

S&A Generators answered the call, and immediately dispatched Blessing, our generator refill specialist, to the client in Escourt. He made sure that his tank had enough fuel for the diesel generator refill, and that the pump was operational, before hitting the road. Blessing noticed when arriving at the client’s premises that the generator was almost completely out of fuel.
The lid is opened so that the generator refiller can access the pump and assess the meter.
The first step in the diesel generator refilling process is to position the S&A Generators vehicle so that it is close enough to the generator for the pump to reach. Then, the pump’s pipe is pushed through a window and extended to the generator. Now the refilling process can begin!

This generator refill took a total of two hours, as the generator’s fuel tank was of a high capacity. Once the tank was filled up, all that was left to do was to ensure that the generator was set to auto and wish the satisfied client farewell.
