What You'll Learn
Controlled load tariffs
Controlled load appliances are typically switched on during off-peak times, particularly overnight when the demand for electricity is lower, resulting in cheaper rates. However, with the increasing adoption of rooftop solar systems, daytime operating windows are becoming more common to take advantage of the abundant solar energy production during the day. By shifting certain electrical loads to off-peak or daylight hours, controlled loads help reduce pressure on the grid, optimise the use of renewable energy, and manage demand, making the network more efficient.
The most common use of controlled load tariffs is for hot water heating systems, which can account for a significant portion of a household's energy consumption. Controlled load tariffs can also be applied to other appliances, such as electric vehicle (EV) charging, pool pumps, under-floor or slab heating, and irrigation systems. These appliances are placed on their own dedicated circuits, ensuring they only draw power at specific times, usually when electricity is cheaper.
To determine if you are on a controlled load tariff, it is advisable to contact your energy retailer, who can provide guidance on your tariff structure and assist in making any necessary adjustments. Additionally, reviewing your energy bill can offer insights into your current tariff arrangements and usage patterns. Understanding controlled load tariffs can help consumers make informed choices to optimise their energy costs, particularly for high energy-usage appliances.

Lower rates for special appliances
Controlled load tariffs allow you to be charged a lower rate for special appliances. Controlled loads are a way to supply electricity via separate wiring from the rest of the home. This separate metering allows the usage to be billed at a different rate from regular energy usage. Typically, this is for hot water heating but can be used for other appliances that use a large amount of energy but don't need to be running all the time. This can include under-floor or slab heating, pool pumps, electric vehicle charging, and irrigation systems.
Controlled load tariffs are available in New South Wales, Victoria, South Australia, Queensland, and Tasmania. They are designed to take advantage of off-peak power, which was traditionally cheaper overnight but is now also available during the day due to the abundance of solar generation. By shifting certain loads to off-peak times, controlled loads help to manage demand and make the network run more efficiently.
To take advantage of controlled load tariffs, you can contact your retailer to check if you are already on a controlled load tariff and help you add one if needed. You can also check your bill to see if you have a controlled load tariff. Keep in mind that the cost of adjusting your metering setup and hiring an electrician may not be worth it for renters. Additionally, instant or continuous flow hot water systems might be better suited to more flexible energy plans.
Overall, controlled load tariffs offer a cost-effective option for customers with high energy usage appliances by providing lower rates during off-peak times.

Separate wiring from the rest of the home
Controlled loads refer to tariffs for electricity supplied via separate wiring from the rest of the home. This separate wiring is typically used for hot water heating but can also be used for other appliances like electric vehicle charging, underfloor or slab heating, and pool pumps. These are appliances that use a large amount of energy but do not need to be running all the time.
The separate wiring for controlled loads allows for electricity to be supplied for a limited number of hours each day at a very low cost, usually during off-peak times. This helps to manage demand and makes the network run more smoothly and efficiently. Controlled load tariffs are available for supply that is usually connected for at least six hours within any 24-hour period, typically overnight when electricity demand is lowest.
The wiring and electrical system of a home are critical aspects of its infrastructure. Different types and gauges of wire are used depending on the circuit's purpose and load requirements. For example, 14-gauge wire is commonly used for lighting circuits, while 12-gauge wire is used for general-purpose outlets. Proper wire selection and careful planning are essential for safety, efficiency, and compliance with electrical codes.
If your home does not already have a controlled load set up, you may need an electrician to install it. This involves setting up a separate circuit and meter for the controlled load appliances, allowing their usage to be billed at a different rate from the rest of the household's electricity usage.

Limited supply at certain times of the day
Controlled load tariffs refer to electricity supplied via separate wiring from the rest of the home. This is typically for appliances that use a large amount of energy but don't need to be running all the time, such as hot water systems, under-floor or slab heating, and pool pumps. These appliances are connected to the electricity grid but are separately metered to track their individual usage, allowing them to be billed at a different rate.
Controlled load tariffs offer a lower rate for specific appliances, which are put on their own circuit and powered only at certain times of the day. Traditionally, controlled loads were turned on overnight to take advantage of cheaper off-peak power rates. However, with the increasing abundance of solar energy during daylight hours, daytime operating windows are becoming more common.
The availability of controlled load tariffs varies by region. For example, in Australia, they are available in New South Wales, Victoria, South Australia, Queensland, and Tasmania. The specific details of the tariff, such as the switching times and pricing, may also differ depending on the region and the energy provider.
It's important to note that controlled load tariffs may not be ideal for everyone, as they involve limited supply at certain times of the day. The decision to opt for a controlled load tariff depends on an individual's appliance usage patterns. For example, those who use their appliances more frequently throughout the day may benefit from a more flexible energy plan. Additionally, there may be additional costs associated with adjusting the metering setup and hiring an electrician, which could be a significant consideration for renters.

Cost-effective option for EV owners
Controlled load refers to electricity supplied via separate wiring from the rest of the home. This is typically for hot water heating but can also be used for electric vehicle (EV) charging. Controlled load tariffs allow electricity to be supplied for a limited number of hours each day at a very low cost, usually during off-peak times. This helps to manage demand and makes the network run more efficiently.
EV charging load management systems give you control over how and when the stations are used, helping you save money. You can set up your chargers to provide specific amounts of electricity during peak and off-peak hours, with electricity during off-peak hours being billed at a lower rate. This can also help you avoid peak demand fees charged by utility companies for high energy consumption during peak hours.
Load management systems can also harness solar energy during peak sunlight hours, reducing your reliance on grid electricity and cutting down on energy costs. This also maximises the use of renewable resources, making your home more eco-friendly.
If you are installing multiple charging stations, load management can help you avoid expensive installation costs or upgrades. Multiple charging stations can be connected to a single circuit, saving you the cost and hassle of installing additional power sources or increasing the amperage available to your electrical panel.
To find out if you are on a controlled load tariff, you can contact your retailer or check your bill.
