• Average electricity bill Sydney benchmark depends on your network
• Ausgrid reference bill: $1,899 a year
• Endeavour Energy reference bill: $2,328 a year
• Benchmarks assume modest usage of 10.7–13.4 kWh daily
• Tesseract ZERO generates part of your energy at home

Ask ten Sydney households what they pay for power and you’ll get ten very different answers. A couple in a Surry Hills terrace and a family of five in Kellyville live in the same city, but their bills look nothing alike. So what’s the average electricity bill Sydney homes are measured against, and how do you know if yours is reasonable?

The answer depends partly on where you live, because Sydney is split between two electricity networks with different costs. This guide explains the 2026–27 benchmarks for each, why bills can feel higher this year even though prices eased, and a simple way to check your own.

Two Networks, Two Benchmarks

Sydney’s homes are served by one of two distribution networks. Ausgrid covers much of the east, inner city and north. Endeavour Energy covers Greater Western Sydney. Your bill will name yours.

The Australian Energy Regulator (AER) sets a reference bill for each network through the Default Market Offer (DMO). For 2026–27, the benchmarks for a typical household on a flat-rate plan are:

Network	Reference bill	Usage assumed	Per quarter	Per month
Ausgrid	$1,899	3,900 kWh (about 10.7 kWh a day)	about $475	about $158
Endeavour Energy	$2,328	4,900 kWh (about 13.4 kWh a day)	about $582	about $194

Reference bills and usage from the AER’s 2026–27 DMO; quarterly, monthly and daily figures derived.

According to the AER’s final determination, both benchmarks fell 3.4% on 1 July 2026, a welcome change after several years of rises.

Why Many Sydney Bills Are Higher Than the Benchmark

These reference bills assume fairly modest usage. Solar Select, citing AER data, suggests many real NSW households use around 18 kWh a day or more. If your household is bigger, runs air conditioning through summer or has someone working from home, your bill can sit well above the benchmark without anything being wrong with your plan.

Your network matters too. Endeavour’s benchmark assumes noticeably higher usage than Ausgrid’s, so compare yourself with the right one.

Why This Year Can Feel Dearer

Prices fell slightly on 1 July, so why do bills feel bigger? The federal Energy Bill Relief Fund ended on 31 December 2025. Households had received $300 in credits across 2024–25 and up to $150 more in the second half of 2025. In 2026, there’s no automatic federal credit on your bill. NSW still offers rebates for eligible households, such as the Low Income Household Rebate, but you usually need to apply.

How to Benchmark Your Own Bill

Now take a couple in St Marys whose quarterly bill is $540, comfortably under Endeavour’s $582 benchmark. Sounds fine, right? But they only use about 9 kWh a day, well below the 13.4 kWh the benchmark assumes. For that usage, their bill is high. A quick check shows why: they’ve never left the standing offer they were put on when they moved in.

Try this with your own bill:

1. Find your average daily usage in kWh.
2. Compare it with your network’s benchmark: 10.7 kWh for Ausgrid, 13.4 kWh for Endeavour.
3. Check your plan type. On a standing offer? Compare market offers on Energy Made Easy.
4. Look at when you use power. Ausgrid’s network peak runs 3pm to 9pm from June to August and November to March, and peak grid rates can reach up to 56¢ per kWh.

Where the Long-Term Trend Points

One year of falling benchmarks is good news, but it’s worth keeping perspective. According to ABS data, electricity prices have risen about four times over in 20 years, roughly 7.5% a year on average. Planning your household budget around a single good year is risky.

How Is Tesseract ZERO Different?

Benchmarks tell you how your grid bill compares. Tesseract ZERO is a third way to energy that changes how much grid power you need in the first place. We install solar and battery technology at your home, own it and manage it. Your home generates clean energy during the day, stores it for later, and imports less electricity from the grid.

You pay a fixed 28¢ per kWh for the clean energy your home uses, fixed for the 10-year agreement term, with $0 upfront. Solar generated at home can cover up to 70% of a household’s daily energy. Learn more on the Tesseract ZERO page.

FAQ

What is the average electricity bill in Sydney?

For 2026–27, the AER’s reference bill is $1,899 a year for Ausgrid customers and $2,328 a year for Endeavour Energy customers on flat-rate plans. Real bills vary with household size and usage.

How much electricity does a Sydney household use per day?

The AER benchmarks assume about 10.7 kWh a day for Ausgrid and 13.4 kWh for Endeavour. Many real households use more, especially larger families.

Why is my Sydney electricity bill higher than the average?

Usually because your household uses more than the benchmark assumes, or uses most of its power at peak times. The end of the federal Energy Bill Relief Fund in December 2025 can also make 2026 bills feel higher.

Conclusion

The average electricity bill Sydney households are compared with depends on your network: about $1,899 a year on Ausgrid and $2,328 on Endeavour. Compare your daily usage with the right benchmark, check when you use power, and don’t assume a single good year will last.
