If you’ve ever glanced at your energy bill and noticed a section labelled "controlled load" or "off-peak usage" but weren’t sure what it meant, you’re not alone. Many Aussie households could be missing out on real savings simply by not understanding how off-peak electricity works—or how a controlled load might slash their energy costs.
In this guide, we’ll demystify off-peak electricity, explain what a controlled load is, and show how using off peak for electricity can lead to big savings. Plus, we’ll explore how you can use tools like Power Market to compare and switch to the best energy plans for your needs.
Understanding Off-Peak Electricity
Off-peak electricity refers to power used during times when energy demand is low—usually late at night or early in the morning. During these hours, electricity providers charge reduced rates because the grid is under less stress.
These lower rates offer a golden opportunity for homeowners who can schedule certain appliances to run during off-peak hours. If you’ve got an electric hot water system, pool pump, or even a heat bank, you could be tapping into cheaper energy without even realising it—provided your property is set up with a controlled load.
What Is a Controlled Load?
A controlled load is a separately metered circuit on your electricity plan that powers specific high-usage appliances—typically outside of peak hours. This setup allows these appliances to draw from off-peak electricity and benefit from cheaper rates.
You might see Controlled Load 1 or Controlled Load 2 on your energy bill. Here’s what they mean:
Controlled Load 1: Typically runs for 6–8 hours overnight. Ideal for electric hot water systems.
Controlled Load 2: Offers more flexibility—up to 18 hours/day, but at a slightly higher rate than CL1.
These options vary slightly depending on your electricity provider and your state (NSW, VIC, QLD, etc.), but the concept is the same: you're getting discounted energy for appliances that don’t need to run during the day.
How Does Off-Peak Electricity Work With Controlled Load?
When you’re set up with a controlled load tariff, your electricity usage is split into:
General Usage – Power used at any time of day, typically for lights, devices, TV, and other everyday appliances.
Controlled Load Usage – Power used by select appliances during off-peak hours, charged at a lower rate.
These two are measured separately through your electricity meter. Your power company can then charge different rates for each. If your energy plan supports off-peak for electricity, this setup could offer significant savings.
Which Appliances Use Controlled Load Electricity?
Not all appliances qualify for a controlled load. Only devices hardwired into your home's electrical system can be billed this way. Common examples include:
Electric hot water systems
Underfloor heating systems
Storage heaters (heat banks)
Swimming pool pumps
Some large electric ovens
If you're unsure which of your appliances are connected to a controlled load, your electrician or energy provider can help clarify.
The Benefits of Off-Peak Electricity and Controlled Load
1. Lower Energy Bills
This is the big one. Off-peak electricity rates can be 30% to 60% cheaper than standard tariffs. If you use a lot of energy for heating water or running a pool filter, a controlled load setup could save hundreds each year.
2. Automatic Scheduling
Controlled load appliances don’t require you to manually switch them on or off during off-peak hours. The system is automated, so your hot water will be heated at night without you lifting a finger.
3. No Behaviour Change Required
Unlike time-of-use tariffs that require you to consciously shift your energy usage, a controlled load setup makes saving money effortless. Once installed, it just works.
Downsides to Consider
While off-peak electricity and controlled loads offer savings, there are a few things to keep in mind:
Appliance Limitations: Only certain appliances can be connected to a controlled load.
Timing Constraints: You might not have hot water immediately if your usage exceeds the system's nightly output.
Availability: Not all energy providers offer controlled load tariffs, and availability varies by state.
How to Know If You’re on a Controlled Load Tariff
Check your electricity bill or log into your energy retailer’s portal. Look for terms like:
Controlled Load 1 / Controlled Load 2
Off-Peak Usage
Separate Meter Charges
Alternatively, speak to your provider or use Power Market to compare plans and see what tariff types you're currently on.

Who Should Consider a Controlled Load Setup?
You’ll benefit most from a controlled load if:
You have an electric hot water system or pool pump
You live in NSW, VIC, QLD, or SA (where controlled load tariffs are available)
You want to save money without changing your habits
You don’t need appliances to run during the day
Controlled Load vs Time-of-Use Tariffs: What's the Difference?
Controlled Load = Separate circuit, specific appliances, off-peak electricityTime-of-Use Tariff = Entire home power varies by time (peak, shoulder, off-peak) . Both offer savings, but a controlled load is generally simpler and more predictable—especially if your high-energy-use appliances can be separated out.
Switching to an Off-Peak Plan
Here’s a step-by-step guide to getting started:
Check your meter: Make sure it supports multiple tariffs.
Review your appliances: Identify if your hot water system or pool pump is eligible.
Compare plans: Use Power Market to find electricity providers that support controlled load tariffs.
Contact your provider: Request to switch or set up controlled load metering.
Hire an electrician (if needed): For appliance rewiring or circuit setup.
Final Thoughts
Off-peak electricity isn’t just a buzzword—it’s a practical way to lower your energy bills using a smart, automated setup called a controlled load. If your household relies on electric hot water or has a pool pump running daily, you're probably paying more than you need to.
Make sure you’re not leaving money on the table. Compare energy plans with Power Market and take advantage of off peak for electricity where it makes sense. Find your best electricity deal today with Power Market .
