Introduction: Navigating Rising Industrial Electricity Costs in Australia

In recent years, Australian industries have grappled with escalating electricity costs, impacting profitability and competitiveness. Factors such as grid instability, volatile wholesale prices, and high network charges contribute to this trend. Energy-intensive sectors, including manufacturing, agriculture, and mining, are particularly vulnerable. However, by understanding the drivers behind these costs and implementing strategic measures, businesses can mitigate their impact.

Understanding the Drivers of Rising Electricity Costs

Grid Instability and Reliability Gaps

Australia's transition towards renewable energy sources, while environmentally beneficial, has introduced challenges related to grid stability. The intermittent nature of solar and wind energy can lead to reliability gaps, especially during peak demand periods. This instability often necessitates reliance on backup power sources, increasing overall electricity costs for businesses.

Volatile Wholesale Electricity Prices

Wholesale electricity prices in Australia have experienced significant fluctuations due to factors like fuel cost variability, generator outages, and changes in demand. These price swings can directly affect industrial consumers, making budgeting and financial planning more complex.

High Network Charges

Network charges, which cover the cost of transmitting electricity from generators to end-users, constitute a substantial portion of industrial electricity bills. In regions with extensive infrastructure or lower population densities, these charges can be particularly high, further burdening businesses.

Sectors Most Affected by Rising Electricity Costs

Electricity is a critical input across many industries, but its impact is not felt equally. Sectors that rely on continuous, high-volume energy consumption, or that operate in regions with constrained grid infrastructure, are bearing the brunt of rising electricity costs. Below are the key industries most affected, and how the issue is playing out in real-world Australian operations.

Manufacturing

Australian manufacturers, particularly in heavy industries like metal fabrication, food and beverage processing, chemical production, and textiles, are deeply exposed to rising electricity prices. These operations often run 24/7, using electricity to power machinery, heating, cooling, conveyor systems, and more. Even modest increases in per-kWh costs can significantly erode margins.

Key pain points:

  • Electricity often represents 15–30% of operational overhead in energy-intensive manufacturing
  • Many small to mid-sized manufacturers are on legacy electricity contracts, locking them into outdated and expensive tariff structures
  • Demand charges during peak production hours add significant, often unpredictable, costs

Example: A Brisbane-based plastics manufacturer reported a 38% increase in electricity bills between 2021 and 2024. After conducting an energy audit, they discovered that running large extruders during mid-afternoon peak pricing periods was costing them an additional $6,000 per month. By shifting operations to early morning and late evening slots, and installing a 75 kW solar system, they reduced annual energy spend by over 20%.

Agriculture

Modern agriculture in Australia is heavily mechanised and energy-reliant, especially in areas such as irrigation, climate-controlled storage, and food processing. Energy is vital for powering irrigation pumps, refrigeration units, shearing sheds, and grain dryers. Rising electricity prices are particularly challenging for farmers in remote and off-grid areas, where fuel and diesel backup are also expensive.

Key pain points:

  • Pumping for irrigation can consume up to 70% of a farm’s energy use, particularly in dairy and cotton farming
  • Cold storage for perishable goods, such as fruit or seafood, requires round-the-clock power
  • Many farms are located in areas with weak grid connections or are reliant on diesel generators, compounding costs

Example: In South Australia, a regional horticulture business saw power bills nearly double between 2022 and 2024, largely due to rising network charges and changes to time-of-use pricing. By participating in a local solar-battery co-op and upgrading to high-efficiency refrigeration, they reduced reliance on the grid by 35%, safeguarding margins for seasonal exports.

Mining

Mining operations require vast amounts of electricity for extraction, ventilation, dewatering, processing, and remote camp infrastructure. In remote mining regions, such as Western Australia, Northern Queensland, and the NT, grid access is often limited or non-existent, meaning reliance on diesel, gas turbines, or hybrid power systems. These operations are highly sensitive to fuel and power price fluctuations.

Key pain points:

  • Energy can account for up to 40% of mining operational expenditure in off-grid or remote areas
  • Electricity pricing uncertainty affects long-term project feasibility and investor confidence
  • Environmental pressure to decarbonise operations is increasing pressure to switch to renewables, which require upfront investment

Example: A mid-tier gold mine in Western Australia operating off-grid faced rising diesel costs that increased energy expenses by over $1.2 million per year. In 2024, they invested in a solar-diesel hybrid power system with battery storage, partially funded through ARENA. The transition cut their diesel use by 40%, delivering estimated savings of $8 million over 10 years.

Regional differences in electricity pricing and grid capacity

Electricity prices for industrial users vary significantly across Australia. These differences are driven by a mix of local generation capacity, network infrastructure, transmission distances, and state-level energy policies. If you're operating in a regional or remote area, you're likely paying more per kilowatt-hour than businesses located in major metropolitan centres.

Why location matters

Industrial electricity bills include several cost components that fluctuate by region:

  • Wholesale electricity prices, which depend on generation supply and demand in your zone
  • Network charges, which fund the poles and wires that deliver electricity to your site
  • Environmental and market scheme costs, such as Renewable Energy Target levies
  • Retail margins, which may vary based on market competition in your state

In many cases, network charges alone can account for 30 to 50 percent of a business electricity bill, and these vary widely depending on your location and distributor.

State-by-state trends

South Australian businesses continue to face some of the highest industrial electricity rates in the country, largely due to limited local baseload generation and high reliance on interconnectors. In New South Wales and Victoria, ageing infrastructure and increasing peak demand have pushed up retail and network costs, particularly in urban fringe and growth corridor areas. Queensland tends to have more stable prices due to a mix of generation sources, but businesses are experiencing rising peak charges. Western Australia, especially outside the South West Interconnected System, often incurs added costs due to decentralised networks or reliance on diesel-based systems.

Grid limitations in regional areas

Regional businesses are often at a disadvantage due to constrained grid capacity and limited redundancy. Common issues include:

  • Higher transmission losses and associated charges due to longer distances
  • Supply interruptions or voltage fluctuations during extreme weather
  • Restrictions on connecting large new loads or embedded generation systems

Some areas, such as Central West NSW or far north Queensland, face regular congestion issues that limit power reliability and flexibility. These constraints can lead to unexpected outages, longer approval times for site upgrades, or even caps on rooftop solar exports to the grid.

What you can do if you’re in a high-cost region

If your facility is based in a regional or fringe area, consider the following practical steps:

  • Request a detailed tariff analysis from your energy provider or distributor to ensure you're not paying demand or legacy charges unnecessarily
  • Shift operational loads to off-peak times, especially if you're on a time-of-use or seasonal demand tariff
  • Invest in power factor correction equipment to avoid unnecessary demand penalties on your bill
  • Consider solar and battery systems to offset peak usage and reduce reliance on unstable grid supply
  • Apply for location-specific government grants that support energy upgrades in regional and rural zones (e.g. the NSW Regional Community Energy Fund or QLD Business Energy Savers Program)

Example

A medium-sized metalworks operation in regional Victoria was facing bills over 36 cents per kilowatt-hour due to high demand charges and low power quality. After installing a 100 kW solar system and a power factor correction unit, they reduced their total bill by 28 percent. They also received a co-funded grant under Sustainability Victoria’s Business Energy Advice program.

Strategies to Mitigate Electricity Costs

Invest in Energy-Efficient Equipment

Upgrading to energy-efficient machinery and systems can lead to significant cost savings over time. Technologies such as variable speed drives, high-efficiency motors, and LED lighting reduce energy consumption and associated expenses.

Adopt Renewable Energy Solutions

Implementing on-site renewable energy sources, like solar panels or wind turbines, can decrease dependence on grid electricity. While initial investment costs exist, long-term savings and potential government incentives make this a viable option for many businesses.

Optimize Operational Practices

Conducting energy audits to identify inefficiencies, scheduling high-energy tasks during off-peak hours, and implementing energy management systems can enhance overall energy efficiency.

Leveraging Government Support and Programs

The Australian government offers various programs to assist businesses in managing energy costs:

  • Energy Efficiency Grants for Small and Medium Sized Enterprises: Provides funding to upgrade or replace inefficient equipment, aiming to lower energy use and improve efficiency.
  • State-Based Initiatives: Programs like Sustainability Victoria offer resources and funding to help businesses reduce energy consumption and costs. 

Real-World Example: BOC's Transition to Renewable Energy

BOC, an industrial gas company in Australia, has committed to sourcing nearly half of its energy needs from solar power through a 10-year agreement with Zen Energy and Acen Australia. This initiative is expected to reduce BOC's Australian emissions by 40% by 2035 and demonstrates the practical benefits of adopting renewable energy solutions.
