‍Controlled Load: What It Is and Why It Might Be Right for You

You might have seen the term “Controlled Load” on your electricity bill or plan details, or maybe it popped up during a chat at a recent BBQ. But what exactly is a controlled load, and is it something you should consider for your home? Let’s break it down in simple terms.

What Is Controlled Load?

Controlled Load is a dedicated circuit in your home that's managed by your Distribution Network Service Provider (DNSP). That is, the circuit is turned off and on by them, not by you. The DNSP are the folks who run the poles and wires in your area—not your electricity retailer. The DNSP controls this circuit to help balance the power supply on the grid.

This circuit is hard-wired to high-load appliances in your house that don’t need to be on all the time, like hot water systems, in-slab heating, or pool pumps. Because the DNSP can manage when these appliances run, they charge a lower rate for the electricity used on this circuit compared to your general household usage.

Controlled Load Options

In New South Wales, there are two main types of controlled load: Controlled Load 1 and Controlled Load 2.

• Controlled Load 1: Operates for around 8 hours each day, usually overnight. This is ideal for appliances that don’t require frequent use, like hot water systems for small families.
• Controlled Load 2: Operates for up to 18 hours each day, including a second period during the day. This is better for appliances that need more frequent use, such as large pool pumps or heating systems in colder climates.

You can choose which controlled load mode suits your needs and switch between them, though this requires contacting your retailer to arrange it with the DNSP. Keep in mind, changes are typically limited to a few times per year due to the manual nature of the process.

Is Controlled Load Right for You?

If you don’t have solar panels and you do have an electric hot water system or in-slab heating, a controlled load can be a great way to save money. By running these high-load appliances on a controlled load circuit, you benefit from lower electricity rates.

However, if you have solar panels, it might be more cost-effective to use the solar power you generate to run these appliances. For instance, you could connect your hot water system to your general circuit and use a timer to heat water during peak daylight hours.

Potential Pitfalls

There are a few things to be aware of with controlled load:

• Overheating: If you have a large hot water system but a small family, having Controlled Load 2 might mean your system heats water twice a day, which could be unnecessary and costly. Switching to Controlled Load 1 or using solar power might be better.
• Midday Switching: Some DNSPs, like Essential Energy, have started turning on Controlled Load 1 circuits during the day to absorb excess solar power. While this helps balance the grid, it can lead to unnecessary heating and higher costs for you.
• Weekends: It is common for Controlled Load circuits to be switched on for more time on weekends than on weekdays. Controlled Load 1 will often be running during the day on weekends.
