When Australian businesses search for a commercial electricity broker, they are usually looking for one thing: cheaper power. But for commercial and industrial (C&I) energy users, electricity costs are no longer driven by energy rates alone.
Today, network tariffs, demand charges and seasonal pass-through costs can outweigh the cost of electricity itself. These charges sit outside retailer pricing and, in many cases, cannot be removed by switching providers.
This is where the role of an electricity broker has fundamentally changed.
A modern business energy broker must act as an advisor — helping organisations understand how, when and why they consume power, and how those behaviours interact with increasingly complex network pricing structures.
At Power Maintenance, this advisory role is central to how we support our clients.
The Shift in Commercial Electricity Costs
Over the past decade, Australia’s electricity market has undergone significant structural change. As legacy coal generation exits the system and renewable energy increases, electricity networks have come under growing pressure to manage peak demand.
To protect grid stability, networks now rely heavily on price signals, particularly for large market customers. One of the most significant of these signals is the summer incentive demand charge.
Unlike energy usage charges measured in kilowatt-hours (kWh), demand charges are based on the highest level of electricity drawn during specific periods. For many businesses, this distinction is poorly understood — until it appears as a substantial and unexpected cost on their bill
Incentive Demand Charges: What They Are and Why They Exist
Summer incentive demand charges are network pass-through charges, applied by distribution networks between December and March. Their purpose is to encourage load reduction during peak summer periods when the grid is under the most strain.
The charge is not optional, and it does not come from the electricity retailer. It is applied regardless of who supplies your electricity.
The charge window depends on the tariff a site is assigned to. For example:
- LLVT1 tariff: 1:00 pm – 4:00 pm
- LLVT2 tariff: 4:00 pm – 7:00 pm
If a business records high demand during these windows, the network applies an incentive demand charge based on the highest measured demand. That single moment can influence costs for months.
A Real Commercial Example: When Network Charges Add $18,000
In one recent case reviewed by Power Maintenance, a large commercial client noticed a new line item on their electricity bill:
“Incentive Demand” – $4,514.83 (ex GST)
This charge related to a 442.63 kVA demand recorded during the summer incentive window.
At first glance, the charge appeared to be a one-off anomaly. But when reviewed properly, the broader impact became clear:
- Monthly incentive demand charge: $4,514.83
- Applied across four summer months
- Total seasonal impact: $18,059.32
This cost had nothing to do with energy rates, contract pricing or retailer margins. It was driven entirely by how demand occurred during a specific three-hour window.
Why Tariff Selection Is Critical for Commercial and Industrial Users
The client was assigned to the LLVT2 (Large Low Voltage Transition) tariff, which signals to the network that demand should reduce between 4:00 pm and 7:00 pm during summer.
For businesses running production lines, refrigeration, logistics or continuous operations, this creates a genuine operational challenge. Shutting down during those hours is rarely realistic.
As Nick Halaris, Group Director at Power Maintenance, explains:
“This is where many businesses get caught out. They think electricity costs are about price per kilowatt-hour, but for large market users, tariffs and demand behaviour matter far more than headline rates.”
Changing retailers would not remove the incentive demand charge. The charge comes from the network and applies regardless of supplier.
The solution lies in understanding the tariff, the operational profile and the available mitigation strategies.
Turning Data Into Practical Insight
When Power Maintenance analysed the client’s demand profile further, the cost was reframed in operational terms:
- Total summer incentive cost: $18,059.32
- Approximate production hours during summer (including public holidays): 180 hours
- Effective impact: ~$100 per hour during peak summer periods
This shift in perspective is critical.
Instead of asking, “Can we avoid this charge?”
The more useful question becomes:
“Can we reduce exposure by adjusting operations during those peak hours?”
Even small changes — rescheduling certain processes, staggering equipment start times, or shifting discretionary load — can materially reduce future demand charges.
Why Electricity Brokering Alone Is No Longer Enough
This example highlights a growing issue across the Australian energy market.
Many businesses engage an electricity broker expecting:
- A better rate
- A smoother renewal
- Less administrative hassle
But for C&I customers, this is only part of the picture.
As Nick puts it:
“If your broker isn’t talking to you about demand, network exposure and tariff risk, they’re only doing half the job.”
A true commercial electricity broker must understand:
- Network tariff structures
- Seasonal pricing signals
- Demand calculation methodologies
- How operational behaviour impacts costs
- Where contractual and non-contractual risks sit
Without this knowledge, businesses can unknowingly absorb tens or hundreds of thousands of dollars in avoidable costs.
The Client Perspective
From the client’s side, the experience was eye-opening.
“We assumed the increase was a pricing issue with the retailer,” said Alastair. “Once it was explained that this was a network charge tied to our operating hours, it completely changed how we looked at the problem.”
Importantly, this insight didn’t lead to unrealistic recommendations.
A full production shutdown during peak periods would have saved the charge — but at the cost of wages, output and broader operational disruption. That option was never viable.
Instead, the focus shifted to targeted, achievable adjustments that could reduce exposure without harming the business.
The Evolution of the Energy Broker Role
Australia’s energy landscape is becoming more complex, not less.
As networks invest billions in infrastructure and the generation mix continues to change, demand-based pricing will play an increasingly central role in how commercial electricity costs are calculated.
For businesses, this means:
- Network charges will continue to rise in importance
- Tariff selection will become more consequential
- Demand management will directly affect profitability
- Poor advice will carry long-term financial consequences
This reality requires a different kind of support.
A business energy broker today must act as:
- A procurement specialist
- A risk advisor
- A translator between technical pricing and real-world operations
Power Maintenance: Energy Advisors, Not Just Brokers
At Power Maintenance, our role extends far beyond electricity procurement.
We support Australian businesses with:
- Commercial and industrial electricity brokering
- Network tariff analysis and optimisation
- Demand charge risk identification
- Contract review and lifecycle management
- Ongoing advisory support across market and regulatory changes
As Nick summarises:
“Our job isn’t just to buy electricity. It’s to help businesses understand what’s driving their energy costs — and give them practical ways to manage those drivers.”
For organisations where electricity is a material operating cost, this level of insight is no longer optional.
Looking for an Energy Broker Who Thinks Like an Advisor?
If your electricity bill includes demand charges, network pass-throughs or unexplained increases, switching retailers may not be the answer.
Understanding the why behind your costs is the first step toward controlling them.

What Is the LLVT1 Tariff? (Large Low Voltage Transition 1)
The LLVT1 tariff (Large Low Voltage Transition 1) is a commercial electricity network tariff applied to large business customers connected at low voltage with significant electricity demand.
It is commonly used for commercial and industrial (C&I) electricity users whose maximum demand typically exceeds standard small-business thresholds.
Under the LLVT1 tariff, electricity networks apply summer incentive demand charges during peak periods, usually between 1:00 pm and 4:00 pm on weekdays from December to March. These charges are designed to encourage businesses to reduce electricity demand during periods of peak network stress.
Importantly, LLVT1 charges are network pass-through costs, not retailer charges. This means switching electricity providers will not remove them. Managing costs under the LLVT1 tariff requires operational planning, demand management and expert advice from a commercial electricity broker or energy advisor.
What Is the LLVT2 Tariff? (Large Low Voltage Transition 2)
The LLVT2 tariff (Large Low Voltage Transition 2) is another large-market commercial electricity tariff for businesses connected at low voltage, but with a different peak demand window compared to LLVT1.
For customers on the LLVT2 tariff, summer incentive demand charges apply during 4:00 pm to 7:00 pm on weekdaysthroughout the summer period (December to March). Electricity networks expect demand to reduce during this late-afternoon and early-evening window, when overall system demand is typically highest.
If high demand is recorded during this period, businesses may incur substantial incentive demand charges that can add tens of thousands of dollars to annual electricity costs. As with LLVT1, these charges are driven by how and when electricity is used, not by energy pricing alone.
For this reason, businesses on the LLVT2 tariff often require guidance from an experienced business energy broker to understand tariff exposure, assess operational flexibility and reduce long-term electricity costs.
Tariff structures and demand windows vary by distribution network and may change over time. Businesses should seek advice from a commercial electricity broker or energy advisor to confirm applicability.
