What Is Controlled Load Usage? How It Affects Your Electricity Bills
Many homeowners pay far more for electricity than they actually need, often without realising it. This is often because running high-energy appliances at the wrong times can result in significant financial loss. Understanding what is controlled load usage could be the key to lowering your bills without changing your daily routine. In this article, we’ll explain how controlled load works and share practical tips to help you manage your energy use more effectively and lower your electricity costs.
What Is Controlled Load Usage
In Australia, controlled load refers to a specific electricity rate applied to certain high-energy appliances, with their usage measured separately from the rest of the household’s electricity. These appliances typically run during off-peak periods, times when overall electricity demand is lower, allowing energy providers to offer a reduced rate.
Types of Controlled Loads
Controlled load rates are divided into two main categories: Controlled Load 1 and Controlled Load 2. Each type is designed for different household needs and appliances.
Controlled Load 1
Controlled Load 1 usually supplies power during fixed periods each day, typically during off-peak hours at night. This type is ideal for appliances that run consistently but do not require continuous power. Compared with standard electricity rates, Controlled Load 1 offers a lower rate, making it a cost-effective option for eligible appliances and helping households reduce their electricity bills without changing their daily routines.
Controlled Load 2
Controlled Load 2 provides power for longer periods, covering both nighttime and daytime, which offers greater flexibility for households. It is suitable for appliances that need to run at various times throughout the day. While the rate for Controlled Load 2 is slightly higher than Controlled Load 1, it is still below standard electricity rates. This type balances flexibility with cost savings, giving homeowners the ability to run appliances more freely while still taking advantage of off-peak pricing.
How Controlled Load Usage Benefits Your Electricity Bills
By using a controlled load tariff, you can better manage when high-demand appliances operate. Shifting their usage to quieter periods helps make energy patterns more predictable and allows households to get the most out of their electricity supply.
Lower Costs by Avoiding Peak-time Usage
Using high-demand appliances during off-peak or controlled load periods can help reduce electricity costs, especially if your household is on a time-of-use tariff. Appliances such as electric hot water systems, slab heating, underfloor heating, and some pool pumps are more commonly suited to controlled load tariffs because they can operate on a dedicated circuit and do not usually need continuous power. This helps you make better use of lower rates and avoid unnecessary spikes in electricity consumption.
Plan Your Appliance Use More Easily
Running major appliances at regular times makes household electricity use easier to manage. When you know when high-demand devices are likely to operate, it becomes easier to plan your daily routine, balance energy use, and avoid running several power-hungry appliances at the same time.
Save More Over Time
The savings from controlled load usage may seem small at first, but they can add up over time. By shifting suitable appliances to lower-cost periods and managing electricity use more carefully, your household can reduce waste, lower energy bills, and become more energy-efficient in the long run.
How Much Can You Save with a Controlled Load Tariff?
By comparing the quarterly electricity bills for single-rate and controlled load tariffs across different Australian states, you can get a clear picture of the potential savings.
State / Network | Single Rate | Controlled Load 1 | Controlled Load 2 |
New South Wales (Ausgrid) | $668.40 | $585.79 | $587.07 |
Victoria (Citipower) | $469.04 | $439.36 | – |
Queensland (Energex) | $635.75 | $581.19 | $584.06 |
These figures highlight that, depending on your state and electricity consumption patterns, switching to a controlled load tariff can lead to noticeable savings each quarter, helping households reduce costs over time. These figures are illustrative examples only. Actual savings vary depending on your network, retailer, tariff, appliance usage, supply charges and controlled load availability.

How to Connect to a Controlled Load Tariff
If you are not currently on a controlled load tariff but would like to use one, you can follow these steps.
Step 1: Contact Your Energy Retailer
The first step is to reach out to your electricity provider. They can confirm whether you are eligible for a controlled load tariff, explain which appliances qualify, and provide details about the applicable rates. This ensures you know if it suits your household before moving forward.
Step 2: Assess Metering Requirements
A dedicated meter is required for circuits using a controlled load tariff. If your home does not already have one installed, you will need to arrange for its installation. Your energy retailer can provide guidance and support to help set this up correctly.
Step 3: Hire a Licensed Electrician
Engage a licensed electrician to install the required metering equipment and set up the dedicated circuit. This ensures that everything meets legal requirements and safety standards.
How to Use Your Controlled Load Efficiently
Simply connecting to a controlled load tariff is not enough. To get the best results, you also need to plan your energy use carefully and make the most of the appliances that run on it.
1. Monitor Energy Usage
Understanding how your household uses electricity helps you make better use of a controlled load tariff. Start by checking which appliances run on controlled load, when they operate, and how much they contribute to your total bill. This is especially useful for high-consumption appliances such as electric hot water systems, pool pumps, underfloor heating, and other dedicated circuits.
A portable power station can support smarter household energy management by tracking the input, output, and battery status of the devices connected to it. It helps you see how much power everyday essentials such as laptops, routers, lights, fans, and small appliances use, so you can plan charging, backup power, and daily electricity use with more control.

Its large-capacity design also lets you store energy for later use, helping you keep key devices running during peak periods, outages, or times when you want extra energy flexibility at home.
2. Limit Simultaneous Usage
Avoid running multiple high-demand appliances at the same time. Staggering their operation prevents sudden spikes in electricity consumption and reduces stress on your electrical system. This simple practice ensures that controlled load periods are used effectively, maximising savings and system reliability.
3. Maximise Savings by Combining Solar and Storage
Controlled load can help reduce the cost of running selected high-energy appliances, such as hot water systems, pool pumps, and underfloor heating. However, it usually applies only to appliances connected to a dedicated controlled load circuit, so it works best as one part of a broader household energy plan. To improve overall savings, many households also use energy storage to manage everyday electricity use with more flexibility.
A home battery backup system can store power for later use, support selected household circuits, and keep essential appliances running during outages or unexpected interruptions. For homes with existing rooftop solar or future solar plans, battery storage can also help make better use of daytime generation instead of sending more excess energy back to the grid.
