Industrial vs Commercial Energy Use: Understanding Renewable Savings in Australia
Industrial and commercial businesses drive Australia's economy, but their energy needs and usage patterns differ significantly. While both can benefit from renewables, understanding these sectors can help you understand how clean energy delivers strategic advantages, from reduced costs to improved sustainability, no matter what your business size is.
Understanding the Sectors
What is ‘Industrial’?
Industrial businesses are large-scale operations like manufacturing, mining, heavy processing and refineries. They have intensive energy requirements, especially for heat and power, often running 24/7 at high throughput. In Australia, industry energy use accounts for two-thirds of national energy use, and 44% of end-use energy in total.
What is ‘Commercial’?
Commercial businesses include offices, retail outlets, showrooms, logistics hubs and service centres. Their main energy use is electricity for lighting, HVAC, IT and equipment. While smaller than the industry, commercial sites can still have significant demand, especially at scale or across large portfolios like shopping centres or multi-site companies.
Classification of Solar Energy
Commercial solar installations usually range from 10kW to under 100kW per site. They qualify for Small-scale Technology Certificates (STCs), which provide upfront financial incentives for adopting solar.
On the other hand, Industrial solar usually exceeds 100kW and involves more complex grid integration. Industrial energy use also generates annually tradable Large-scale Generation Certificates (LGCs) under the Renewable Energy Target (RET). These differences between the two affect how businesses plan and fund renewable investments for commercial solar savings.
| Feature | Commercial (<100kW) | Industrial (>100kW) |
| Typical Sites | Retail, offices, small factories | Refineries, large plants, logistics hubs |
| Incentives | STCs (upfront discount) | LGCs (ongoing, tradable credits) |
| Grid Connection | Low-voltage | High-voltage, complex protection |
| Monitoring | Basic | Advanced analytics |
How Renewable Energy Helps
Now, let’s discuss how renewable energy benefits industry and commercial businesses with electricity bill reduction in solar:
Reducing Operating Costs
Industrial facilities spend heavily on energy for many purposes, like to process heat, motors, pumps, and lighting. Transitioning to renewable energy, especially rooftop solar and bioenergy, can help them offset both peak and base load. This leads to significant reductions in energy bills.
Commercial businesses that face rising grid costs can also stabilise expenses and free up capital with the help of renewable energy.
Supporting ESG and Net-Zero Goals
Both sectors are under increasing regulatory and stakeholder pressure to decarbonise. The push for net-zero and science-based targets means renewables can offer measurable results and help commercial and industrial businesses with reduced carbon footprint, improved compliance, and enhanced brand value.

Renewable Technologies for Industry and Commercial Businesses
For Industrial Processes
- Bioenergy (biomass, biogas) fuels boilers and process heaters, providing non-electric heat for operations.
- Solar thermal directly heats fluids for process or cleaning and reduces reliance on gas.
- Geothermal offers stable heat for suitable sites.
- Hydrogen produced from renewable electricity is evolving for deep industrial decarbonisation.
For Commercial Applications
- Rooftop solar is the most common solution as it reduces electricity bills.
- Commercial battery storage works with solar to manage peak loads and backup needs.
- Demand-side management tools like smart controls or digital analytics boost efficiency and grid resilience.
Facts Related to Energy Use in Australia
- Australia’s industry uses more than half its energy for processing heat, often over 100°C, mostly supplied by gas and coal, but renewable substitutes are available for all temperatures.
- Short-term, economically viable renewable heat substitution could save up to 56PJ/year, equal to 12% of industrial gas use for heat.
- Rooftop solar potential across industrial zones in Australia is estimated to generate 19GW with 26,464GWh annual output.
While technology exists for renewable industrial heating and commercial solar, deployment is slowed by concerns related to cost, process redesign, and risk tolerance. Payback expectations are short, but innovation and funding models like leasing and power purchase agreements help lower capital barriers.
Future Trends
The energy market in Australia is transforming and favouring renewable energy, with a major focus on innovation. Upcoming energy solutions like green hydrogen, advanced storage, and digital controls can offer greater cost savings and resilience. The shift to electrification, integration of electric vehicle fleets, and new regulatory standards will shape how both industrial and commercial sectors adopt renewables.
Conclusion
The commercial and industrial business sectors in Australia can no longer ignore the benefits of renewable energy. From reduced operating costs to decarbonisation, modern solar, bioenergy, and advanced controls offer a proven path forward for any site size or business type.
With government-backed incentives and emerging technologies making clean energy more accessible, smart businesses choose renewable energy today, not just for savings, but to future-proof against energy volatility and climate pressures.
