So just who is the cheapest electricity provider in Sydney?
Working out the best deal on electricity can be confusing. There are many retailers, a range of rates, and different plan conditions. Comparing them to find the cheapest option for your home takes a little knowledge about how electricity gets to your house and what makes up your bill.
Asking “what is the best electricity provider in Sydney?” doesn’t have a single answer. First, it helps to understand the basic charges on a bill and why they vary. After that, you can compare ‘apples with apples’ and make a confident choice.
Getting electricity into your house to power lights, hot water and appliances involves a few parts of the system. There are companies that own and operate the poles and wires in different areas, and there are energy retailers who sell electricity and send you a bill. Your total cost depends on how much you use, when you use it, and which plan you choose.
Understanding your electricity bill
What you pay each month includes a usage component and a daily supply component. Here are the main parts to know about in Sydney:
Cost per kWh (usage)
This is usually the largest part of your bill. It is the variable cost for each unit of electricity you use, measured in kilowatt-hours (kWh). Electricity prices are influenced by demand: during busy evening periods (often called peak), rates are higher; overnight off‑peak periods are usually cheaper; shoulder periods sit in between. Shifting some appliance use to cheaper times can reduce your costs.
NSW context: From 1 July 2025, the Australian Energy Regulator’s Default Market Offer (DMO) for 2025–26 sets higher reference prices in NSW compared with last year. That means many households will see higher electricity bills, although market offers can still be cheaper than the regulator sett DMO.

Controlled Load (NSW)
A controlled load is a separate, metered circuit that can power eligible high‑usage appliances such as electric hot water. In NSW this is commonly called Controlled Load 1 or 2. Controlled load rates are typically lower and run for set hours outside peak times. Whether it helps depends on your setup and when the appliance runs.
Supply charge (daily)
This is a fixed daily charge for being connected to the grid. It helps pay for the network and metering services. Because it’s a fixed cost, plans often trade off the daily charge against the usage rate. Households with higher usage sometimes prefer a higher daily charge with a lower usage rate, while lower‑usage homes may prefer the reverse.

What about discounts and deals?
Retail electricity is competitive. Plans may include bill credits or discounts to attract new customers. If you haven’t compared for a while, earlier discounts may have expired and you could be on a default or standing offer. Re‑shopping can reduce your bill. The Australian Energy Regulator explains default market offers and plan structures on Energy Made Easy.
For broader background on national price trends, see the Australian Energy Market Commission (AEMC).
