Protect your backup power systems with regular servicing
Your generator might go weeks or months without being called on, but when Brisbane’s grid power goes down, you need it to start straight away. For businesses relying on backup power, a failed generator can quickly become a much bigger problem, particularly in hospitals, data centres, and facilities storing temperature-sensitive stock.
Regular preventative maintenance gives you a chance to pick up problems while they’re still small, rather than discovering them during an outage.
- Finds common issues like flat batteries, blown fuses, and low fluid levels before they stop the generator from starting
- Keeps oil, coolant, filters, belts, and control systems in good working order, so the generator is ready when it’s needed
- Picks up deteriorating fuel before it causes problems. Diesel can degrade over time, particularly when a generator sits unused for long periods
- Helps extend the working life of the generator and get more from the investment you’ve already made
- Reduces the chance of being hit with a major repair or replacement bill further down the track
Our maintenance programs are built around three checks that cover many of the most common reasons generators fail to start.

Our generator services in Brisbane
It is imperative that your generator be serviced regularly to ensure it can start in the event of a power outage. Your investment in a generator is justified only if it starts and provides power when required, so there is no interruption to your organisation’s operations.
There are 3 key preventative maintenance services that address the most common reasons your generator won’t start, helping our valued clients avoid unnecessary maintenance costs.
1. SCHEDULED Maintenance
Flat batteries and blown fuses are far more common causes of a failed start than most people expect, and a scheduled maintenance program catches both long before they become a problem.
We run monthly, bi-monthly, quarterly, six-monthly and annual maintenance programs for generators across Brisbane, each one thorough and methodical, so you know exactly where your generator stands. The cost of a scheduled service is small next to the cost of a generator that doesn’t start when your business needs it.
2. MAINS FAILURE TESTING
On average, a standby generator is called into action about once a year. That’s not a lot of runtime, and it means problems can sit undetected between uses. A mains failure test is the most reliable way to know, for certain, that your generator will pick up the load when it counts.
We recommend this test at least once a year. It checks that the transfer from mains supply to generator supply happens the way it’s designed to, and it’s carried out by our qualified, experienced generator electricians.
3. DUMMY LOAD TESTING
Dummy load testing is useful for commercial facilities or industrial sites that can’t interrupt their power supply to test a generator under normal site load, or for sites that simply don’t have enough load available.
Standby generators can spend long periods running with little or no load. Over time, this can lead to poor combustion, carbon build-up, and other engine issues that may reduce performance when the generator is finally called on during an outage.
Running the generator under a controlled load helps bring the engine up to the temperatures and pressures it was designed to operate at. If problems are picked up early enough, this can help burn off carbon deposits, reduce glazing, and prevent further deterioration.
Genergy has invested in a fleet of custom-built portable resistive load banks, allowing us to test generators under a controlled “dummy” load without interrupting your site’s power or day-to-day operations.
During testing, one of our qualified technicians stays with the generator and records electrical and mechanical readings at 15-minute intervals. Once complete, you receive a detailed load test report showing how the generator performed under load.
Our scheduled generator maintenance program
Every maintenance program includes thorough electrical and mechanical checks. , Consumables such as oil, coolant, and batteries are only replaced when required. This ensures you won’t pay for anything your generator doesn’t need and prevents needless environmental waste. As added peace of mind, you’ll get a full service report at the end of every visit for your own records and compliance requirements.
- Monthly, bi-monthly and quarterly services: 55-point checklist
- Six-monthly services: 65-point checklist
- Annual service: 78-point checklist
- Filter replacements: Engine oil filters and fuel Filters
- Laboratory analyses: Coolant, fuel, engine oil
We work with all generator sizes and brands
We maintain generators of all sizes and brands across Brisbane, from smaller 6kVA units through to paired 2,250kVA systems that synchronise and share load automatically. With experience across such a broad range of equipment, there’s a good chance our team has worked on a generator like yours before.

Frequently asked questions
We service standby generators across a broad range of Brisbane sites, from hospitals and aged care facilities to data centres, commercial and residential high rises, and essential services like police and ambulance stations. Whatever the setting, our technicians understand what’s at stake if a generator doesn’t start when it’s needed and service each site with that in mind.
As a general guide, a commercial generator needs a service every 100 to 150 hours of run time. Most standby Brisbane generators rarely clock up that many hours in a year, so we set most maintenance programs by calendar, monthly, quarterly, six-monthly or annual, rather than run hours. Every visit includes thorough electrical and mechanical checks , which keeps your generator ready to deliver reliable power the moment mains supply drops out.
This depends heavily on the type of generator. A small portable petrol unit might only last 1,000 to 2,000 hours of use, while a commercial stand-by diesel generator, one of the most common kinds we work on across Brisbane, can operate for often decades of service, when it’s maintained with quality equipment and a proper schedule. The gap between those numbers comes down almost entirely to servicing.
A standby generator might sit unused for months, but it still needs to be ready to start and take on a full load the moment the power goes out. Even when it isn’t running, fuel, fluids, batteries, and other components can deteriorate over time. That’s why maintenance shouldn’t be based on run hours alone. Regular checks help pick up the kinds of issues that could otherwise stop the generator from delivering reliable power during an outage.
Generally, yes. A well–maintained commercial stand-by generator is built to last for decades, so a repair is usually the more cost-effective option unless your unit is well past that mark or the fault is major, such as a cracked block or a failed alternator. We provide generator repair services alongside our servicing programs, so if a scheduled visit turns up a fault, our team can often quote the repair on the spot instead of sending you to another contractor.
Most generator problems tend to come back to the same few issues. It might be a weak or corroded starter battery, fuel that’s taken on water or sludge, or a voltage regulator fault that leaves the engine running without producing power.
Overheating and low oil pressure are common as well, often linked to low coolant, worn belts, or blocked filters triggering a safety shutdown. Standby generators that rarely run under load can also build up carbon over time, which can gradually reduce how much power they’re able to deliver.
Regular servicing helps catch these problems early, while they’re usually much simpler and less expensive to fix.
