Are you actually set up to take full advantage of Australia's 3 Free Electricity Hours?

What Are Australia's 3 Free Electricity Hours?

Since July 1, 2026, eligible households in NSW, South East Queensland, and South Australia get up to 3 hours of free electricity every day through the government's new Solar Sharer Offer (SSO). The free periods run 11am to 2pm in NSW and South East Queensland, and 12pm to 3pm in South Australia, with a daily cap of 24 kWh of free usage.

 

Sounds great. But here's the real question: are you actually set up to take full advantage of it?

 

If you're home during those hours and can run appliances, you'll save something. But if you want to save meaningfully — hundreds, not tens, of dollars — you need a strategy. The most effective strategy by far is charging a home battery during the free window, then using that stored energy when grid prices spike in the evening.

 

Let's walk through every option, from best to good.

The Smartest Strategy: Charge a Home Battery During Free Hours

Here's why this is the #1 approach.

 

Without a battery, you can only use free electricity while it's running — during 11am to 2pm (or 12pm to 3pm in SA). Anything you don't consume in that window is wasted. With a home battery, you're not limited to real-time usage. You're storing 3 hours of free electricity and spreading it across the entire evening.

 

Here's how it works in practice:

  • During free hours: Your solar panels generate power, and your battery charges from the grid for free. With a system like Spiring's Core (26.6 kWh), you can capture well over the daily 24 kWh free cap in a single charge.
  • Peak evening (4pm-9pm): Your home draws from the battery instead of the grid. You're running your appliances, cooking dinner, watching TV — all on electricity you got for free earlier in the day.
  • Overnight: Any remaining battery capacity covers your baseload (fridge, modem, standby devices) until solar kicks in again the next morning.

The result? You shift your entire evening electricity consumption to free daytime power. That's where most households spend 40-60% of their daily electricity costs — and you've effectively eliminated it.

 

A 13.3 kWh battery (like the Spiring Eco tier, starting at $6,499 incl. GST) can store enough free electricity to cover a typical 2-person household's evening usage. For larger households, the 26.6 kWh Core ($7,299) or 37.2 kWh Ultra ($11,999) tiers easily capture the full 24 kWh free daily cap.

 

And because Spiring plans include monthly electricity credits on top, your savings stack: free daytime charging + electricity credits + reduced evening grid consumption.

How Much Could You Save with a Home Battery? (With Data)

Let's put numbers on it. Here's a comparison of three typical household scenarios under Solar Sharer:

Scenario Free Hours Usage Evening Shift Est. Annual Saving
Solar + Battery
e.g. Spiring Core, 26.6 kWh		 Charge full battery every free window 8‑10 kWh shifted to evening $1,100 – $1,500 Best
Solar Only, No Battery Run dishwasher + pool pump + laundry None — can't store $150 – $300
No Solar, No Battery Run appliances during free hours only None — can't store $80 – $200

*Based on an assumed grid rate of $0.40/kWh and typical household evening usage of 8-12 kWh.

The difference is stark. A battery doesn't just let you use more free electricity — it lets you use free electricity at a time when it's most valuable: evening peak. Without a battery, you're limited to whatever appliances you can run between 11am and 2pm on a workday.

 

Even running a dishwasher, washing machine, and pool pump during free hours every day saves only around $200–$300 a year. With a battery, that figure jumps 5x because you're displacing expensive evening grid consumption.

Run These High-Energy Appliances During the Free Window

Don't have a battery yet? You can still make the 3 free hours count. The key is moving your heaviest electricity loads into the free window.

These are the appliances that make the biggest difference:

  • Pool pump (if you have one) — runs 2-4 hours daily, often the single biggest regular load after HVAC. Schedule it 11am-2pm.
  • Dishwasher — delay start timer. Running a full cycle uses 1.5-2.5 kWh per load.
  • Washing machine and dryer — front-load the laundry during free hours. A dryer cycle uses 2-4 kWh.
  • Pre-cool your home — run your air conditioner hard during free hours to bring the house temperature down before 2pm. The cool mass will carry you through the afternoon without the AC kicking in again.
  • Water heating — if you have an electric hot water system on a timer, shift it to the free window. A full tank uses 4-6 kWh.
  • Oven and cooking — batch-cook or roast during free hours. Reheat later.

Tip: If you have a smart meter, check your energy usage data (most retailers provide a daily breakdown). Find the appliances that appear outside free hours and see if they can be rescheduled.

Charge Your EV for Free (But Watch the 24 kWh Cap)

EV owners are in a sweet spot with Solar Sharer.

 

Plugging in your EV during free hours means you're effectively getting free fuel. But there's a catch: the 24 kWh daily cap.

 

Most Australian EVs have batteries between 40 kWh and 85 kWh. A full charge for a Tesla Model 3 (60 kWh) at the free rate would use 24 kWh of your daily allowance — leaving zero for the rest of your home. And the charge wouldn't be complete either.

Practical strategy:

  • Use the free window to top up an already partially charged EV. A top-up of 10-20 kWh during free hours is realistic within the 24 kWh cap.
  • If you have both an EV and a home battery, prioritise the battery. Charging your battery gives you a return of $0.40/kWh (displacing evening grid use), while topping up the EV saves roughly $0.25-0.30/kWh (vs standard off-peak EV rates).
  • Schedule your EV charging after the battery is full. If you have a smart charger, set it to start at the beginning of the free window. The battery will charge first (typically 1-2 hours), then the remaining free time goes to the car.

Smart Scheduling: Automate Your Free Hour Usage

The most practical obstacle to using free hours is remembering to use them. Most people aren't home at 11am on a Tuesday.

The solution is automation:

  • Smart plugs (around $20-40 each from Kmart, Bunnings, or online) — set timers for your dishwasher, washing machine, pool pump. They switch on at 11am and off at 2pm automatically.
  • Appliance delay start — most modern dishwashers and washing machines let you set a delayed start. Pre-load the night before and set it to begin at 11am.
  • Smart EV charger — programs like the OVO EV plan let you schedule charging to the free window. Set it and forget it.
  • Battery management system — Spiring's system automatically optimises battery charging during free hours and discharges during peak evening times. No manual scheduling needed.

One-time setup, ongoing savings. Spend 30 minutes setting timers and smart plugs, and those 3 free hours work for you every single day — even when you're at work.

Frequently Asked Questions

Everything you need to know about making the most of Australia's 3 free electricity hours.

Not directly — but a home battery does exactly this. During the free window, your battery charges from the grid at no cost. That stored energy is then available for your home in the evening, when grid prices are highest. Without a battery, any free electricity you don't use during the 3-hour window is lost.

No, but it helps. Solar Sharer is available to all eligible households regardless of whether they have solar. If you have both solar and a battery, you get the best outcome.

A typical household with a 13.3-26.6 kWh battery can save $1,100 to $1,500 per year from the free hours alone. With Spiring's monthly electricity credits (up to $1,440/year), total savings can reach $2,500+ annually.

Yes. Spiring's battery systems are fully compatible. The battery charges automatically during free hours and discharges during peak times. Plus your Spiring plan adds monthly electricity credits on top.

Usage beyond 24 kWh during the free window is charged at your retailer's standard rate. For most households, 24 kWh is generous — the average Australian home uses 15-20 kWh per day.

Make Your Free Hours Count

Three hours of free electricity a day is a genuinely valuable opportunity — if you're set up to use it. The households that benefit most aren't the ones who randomly remember to run the dishwasher at lunchtime.

 

They're the ones who put a system in place: a battery to store the free energy, timers to automate their appliances, and a plan that stacks savings.

 

With a Spiring home battery, you get the full package: free daytime charging + monthly electricity credits + automated VPP-ready optimisation. The 3 free hours become the foundation of a much bigger saving strategy, not just a nice bonus.
