Every Synergy Plan Compared (2026): Which One Suits Your Perth Home?
Quick answer: Synergy has two main plans open to new Perth households in 2026: the flat-rate Home Plan (A1) at 33.26c/kWh, and the time-of-use Midday Saver, which charges 8.85c/kWh from 9am to 3pm but 55.33c/kWh from 3pm to 9pm. EV owners can choose EV Add On, which is Midday Saver plus a cheaper overnight rate. The Smart Home Plan and EV Home Plan are closed to new customers. Which one suits you depends on when your home uses power, and whether you have solar, a battery or an EV.
If you live in Perth, you almost certainly buy your power from Synergy. There is no retail competition for most homes on the South West Interconnected System (SWIS), so you can’t shop around between retailers. What you can choose is your plan, and that choice matters more than most people realise. The same household can pay very different amounts depending on the tariff it sits on.
This guide puts every current Synergy residential plan side by side, using the rates that took effect on 1 July 2026. It tells you which plans you can actually switch to, which ones are closed, and which suits a home with no solar, solar only, solar plus a battery, or an EV.
Synergy plans compared: 2026 rates at a glance
Here is every Synergy residential plan most Perth homes will come across, with rates from 1 July 2026. All supply charges and usage rates include GST. The windows apply every day unless the table says weekdays.
| Plan | Supply charge | Usage rates and windows | Who it suits | Open to new customers? |
|---|---|---|---|---|
| Home Plan (A1) | 119.24c/day (about $1.19) | 33.26c/kWh at any time | Homes that use most power in the evening, or that don’t want to think about timing | Yes |
| Midday Saver | 132.78c/day (about $1.33) | 8.85c 9am–3pm; 55.33c 3pm–9pm; 24.34c 9pm–9am | Homes that can shift use into the middle of the day, and most homes with a battery | Yes (advanced meter needed) |
| EV Add On | 132.78c/day (about $1.33) | 8.85c 9am–3pm; 55.33c 3pm–9pm; 24.34c 9pm–11pm and 6am–9am; 19.92c 11pm–6am | Plug-in EV owners who charge at home | Yes (WA-registered plug-in EV and advanced meter needed) |
| Smart Home Plan | 119.24c/day | 63.26c weekdays 3pm–9pm; 33.13c weekdays 7am–3pm and weekends 7am–9pm; 17.43c 9pm–7am | Existing customers only | No (closed) |
| EV Home Plan | 119.24c/day | 23.21c 11pm–4am; 33.26c 4am–11pm | Existing customers only | No (closed) |
Two numbers explain most of the decision. On Midday Saver, power between 9am and 3pm costs about a quarter of the A1 rate. Between 3pm and 9pm it costs about two-thirds more than A1. If your home can push its use into the middle of the day, or cover the evening from a battery, Midday Saver usually comes out ahead. If your evening use is high and you can’t move it, A1’s flat rate is the safer choice.
Worth knowing: Midday Saver’s supply charge is about 13.5c a day higher than A1’s. That adds up to roughly $50 a year, so the cheaper midday power has to save you more than that before the switch pays off.
Which Synergy plan suits your home?
Start with what you have on the roof and in the garage, then think about when your household is home. Here is a simple guide.
| If you have… | Plan that usually suits | Why |
|---|---|---|
| No solar, out during the day | Home Plan (A1) | Most of your use falls in the evening, when Midday Saver is at 55.33c |
| No solar, home during the day | Compare both | Midday Saver can work if you run the washer, dishwasher, pool pump and air con before 3pm |
| Solar, no battery | Usually A1 | Your panels already cover daytime use, so Midday Saver’s cheap window saves little and the evening rate costs more |
| Solar and a battery | Usually Midday Saver | The battery covers 3pm–9pm, and any grid top-up can happen at 8.85c in the middle of the day |
| An EV you charge at home | EV Add On | Midday Saver rates plus 19.92c overnight charging from 11pm to 6am |
No solar
If the house is empty from 8am to 6pm, stay on A1. Your cooking, lights, TV and evening air con would all land in Midday Saver’s peak window. If someone is home during the day, or you work from home, Midday Saver is worth a look. Timers on the dishwasher, washing machine and pool pump do most of the work.
Solar without a battery
This is the case that catches people out. Midday Saver’s cheap window lines up with the hours your panels are already producing, so you get little benefit from it. Meanwhile, your evening use is billed at 55.33c instead of 33.26c. For most solar-only homes, A1 is the better fit. The exception is a home with very low evening use.
Solar and a battery
A battery changes the maths. It stores solar during the day and runs the house from 3pm to 9pm, so you rarely pay the peak rate. On cloudy winter days you can top the battery up from the grid at 8.85c. That is why most Perth battery owners end up on Midday Saver. Midday Saver is also one of the tariffs eligible for Synergy Battery Rewards, the virtual power plant (VPP) linked to the WA Residential Battery Scheme.
An electric vehicle
If you own a plug-in EV registered in WA, EV Add On gives you Midday Saver’s rates plus an overnight band at 19.92c from 11pm to 6am. If the car is home during the day, charging it between 9am and 3pm at 8.85c (or straight from your solar) is cheaper still. EV Add On replaces A1 or Midday Saver rather than sitting on top of them.
Quick tip: Check your recent Synergy bills or online account usage before you switch. If a large share of your grid use falls between 3pm and 9pm and you can’t move it, A1 is usually the safer choice.
Each Synergy plan in brief
Each plan below gets a short summary. Follow the links for the full guide on each one.
Home Plan (A1): the flat-rate default
A1 charges 33.26c/kWh at any time of day, plus 119.24c a day in supply. It is the plan most Perth homes sit on and the one Synergy moves you back to if you opt out of an advanced meter. A1 is simple and predictable. It suits homes with heavy evening use and most solar homes without a battery. It is residential only; homes running a business from the premises are on a different tariff.
Midday Saver: the time-of-use plan open to new customers
Midday Saver has three windows every day: 8.85c from 9am to 3pm, 55.33c from 3pm to 9pm, and 24.34c from 9pm to 9am. The supply charge is 132.78c a day. You don’t need solar, a battery or an EV to join. You do need an advanced meter where one is available in your suburb. There is no fixed term, and you can go back to a Home Plan at any time. Read our Synergy Midday Saver plan guide for worked examples and who it suits.
EV Add On: Midday Saver plus overnight EV charging
EV Add On uses the same supply charge and daytime windows as Midday Saver. It splits the off-peak period so that 11pm to 6am drops to 19.92c, with 24.34c from 9pm to 11pm and 6am to 9am. To be eligible you need a plug-in EV (battery electric or plug-in hybrid) registered with the WA Department of Transport at your address. It is a whole-of-home tariff that you choose instead of A1 or Midday Saver. Our Synergy EV Add On guide covers eligibility and charging costs in detail.
Smart Home Plan: closed to new customers
Synergy lists the Smart Home Plan under plans no longer offered. If you are already on it you can stay, but new customers can’t sign up. Its weekday peak of 63.26c from 3pm to 9pm is the highest of any current Synergy plan, and it is not on the Battery Rewards eligible list. If you want time-of-use pricing, Synergy points you to Midday Saver instead. See our Smart Home Plan vs A1 comparison if you are on it now and wondering whether to move.
EV Home Plan: the older EV tariff
The EV Home Plan is also closed. Existing customers pay 23.21c from 11pm to 4am and 33.26c the rest of the day. New EV owners should look at EV Add On, which has a longer and cheaper overnight window.
Important: If you leave a closed plan, you can’t go back to it. Run the numbers on your own usage before you move off Smart Home Plan or EV Home Plan.
How Synergy pays you for solar exports
Your export rate does not depend on which plan you choose. Most solar homes are paid under the Distributed Energy Buyback Scheme (DEBS), whether they are on A1, Midday Saver or EV Add On.
| Export time | DEBS rate |
|---|---|
| 3pm to 9pm | 10c/kWh |
| Before 3pm or after 9pm | 2c/kWh |
| Daily limit | Rates apply to the first 50 kWh exported each day |
Synergy confirmed there were no changes to DEBS buyback rates in 2026. Because most solar exports happen in the middle of the day, the bulk of a typical solar home’s exports earn 2c. Compare that with the 33.26c you pay on A1 or the 55.33c you pay in Midday Saver’s peak, and the lesson is clear: power you use yourself is worth far more than power you send to the grid. Our DEBS feed-in tariff guide explains eligibility, export limits and how exports are measured.
Some older systems are still on the Renewable Energy Buyback Scheme (REBS), which pays a flat 7.135c/kWh. You keep REBS only while your system stays unchanged. If you add a battery or upgrade the system, you move to DEBS.
Synergy Battery Rewards (VPP)
Battery owners have one more way to earn. Synergy Battery Rewards is the virtual power plant that customers join when they take the WA Residential Battery Scheme rebate (up to $1,300 for Synergy customers). During an event, Synergy can call on your battery to export, and you receive a 70c/kWh activation credit for that energy. Synergy can run up to 30 events a year, and the initial term is two years. It is open to customers on A1, K1, Midday Saver or EV Add On, but not the Smart Home Plan. It is not available where life-support equipment is registered. Read more in our guide to virtual power plants in Perth.
How to switch Synergy plans
You switch plans with Synergy directly. Midday Saver has no fixed term, so you are not locked in. Here is what to expect.
- Check your usage. Look at how much of your grid power you use between 3pm and 9pm. This is the single biggest factor.
- Check your meter. Midday Saver and EV Add On need an advanced (AMI) meter where one is available in your suburb. Western Power is rolling these out across Perth. If AMI isn’t yet available in your suburb, Synergy says you can’t take Midday Saver.
- Allow for meter fees. If your meter needs reconfiguring, Synergy may charge $111.60, or $42.22 if it can be done remotely.
- Give notice. Midday Saver has no fixed term. You can change tariffs with 5 days’ notice and move back to a Home Plan at any time.
- For EV Add On, have your vehicle registration details ready. The rego name and address need to match the account holder or an authorised person at the same address.
Getting the most from your Synergy plan with solar and a battery
The plan you pick works best when it matches your system. A solar-only home on A1 saves most by using power while the sun is up. A home with a battery on Midday Saver saves most when the battery is sized to carry the house through 3pm to 9pm. An EV owner saves most by charging from solar or in the cheapest window.
As a rough guide, most Perth homes pay around $9,500–$13,000 for a ~10 kWh battery before rebates in 2026, or around $5,500–$9,000 after the federal Cheaper Home Batteries program and the WA Residential Battery Scheme. Your price depends on battery size, your switchboard and whether you already have a compatible inverter.

Synergy plans: frequently asked questions
What is the best Synergy plan for solar?
For most homes with solar but no battery, the Home Plan (A1) is usually the better fit. Your panels already cover daytime use, so Midday Saver’s 8.85c midday rate saves little, while its 55.33c rate from 3pm to 9pm makes evening power dearer than A1’s flat 33.26c. Once you add a battery that covers the evening, Midday Saver usually comes out ahead. Check your own usage before you switch.
Can I still switch to the Synergy Smart Home Plan?
No. Synergy lists the Smart Home Plan as no longer offered, so only existing customers can stay on it. If you want time-of-use pricing, the plan open to new customers is Midday Saver, or EV Add On if you own a plug-in EV.
Do I need solar to go on Synergy Midday Saver?
No. Midday Saver is open to any residential customer, with or without solar, a battery or an EV. You do need an advanced meter if one is available in your suburb, and Synergy says you can’t take the plan where advanced meters aren’t yet available.
Does my Synergy plan change my solar feed-in tariff?
No. Under DEBS you are paid 10c/kWh for exports between 3pm and 9pm and 2c/kWh at other times, on the first 50 kWh exported each day, whichever plan you are on. Synergy made no change to DEBS rates in 2026.
Which Synergy plans can join Battery Rewards?
Synergy Battery Rewards is open to customers on A1, K1, Midday Saver or EV Add On who install a battery under the WA Residential Battery Scheme. The Smart Home Plan is not on the eligible list. Members receive a 70c/kWh activation credit for energy exported during events, with up to 30 events a year.
How much is the Synergy supply charge in 2026?
From 1 July 2026, the Home Plan (A1) supply charge is 119.24c a day, or about $435 a year. Midday Saver and EV Add On charge 132.78c a day, about $485 a year. Both figures include GST.
