Electric Vehicle Home Plan

What you need to know

The Synergy EV Home Plan is a time of use tariff, which means the consumption or usage rate you pay is based on the time of day you use the electricity. There are 2 time bands that apply all year round.

Smart Home Plan Off- Peak IconEV off peak (11pm to 4am)
Save by shifting the time you charge your EV to during this period.
Smart Home Plan On- Peak Icon Standard home (4am to 11pm)
Equivalent to the Synergy A1 Home Plan (A1) tariff.
Item Price inc. GST
Supply charge 105.1400 cents per day
Standard home electricity charge 29.3273 cents per unit
Everyday EV off peak electricity charge 20.4651 cents per unit

Calculating your cost

The EV Home Plan tariff is lower than the standard residential A1 tariff during the EV off peak period and the same during the Standard home period, so be sure to switch the charging time of your EV to the EV off peak time if you can.

A time of use meter records the amount of energy and what time of day the electricity was used. The rate applicable during that time period is then charged. Check out this example bill to see how the rates are applied and reported.

More information on the EV Home Plan tariff can be found in the Help & advice section for information and FAQs on electricity.

Other fees & charges, including meter prices

Other fees & charges may apply, including the charges for installing a time of use meter in new and existing homes.

Building a new home?

For customers building a new home where electricity has not been connected, please discuss the best type of meter for your electricity use with your electrical contractor or builder to make sure they install the most suitable meter for your needs. If a new meter or reprogramming of your existing meter is required the meter installation or programming fee will be charged in full on your next Synergy bill.

Prices are subject to change from time to time and other fees and charges may also apply. Unless otherwise stated, all prices include GST and are effective at 1 July 2021. By law we calculate our prices to four decimal places. Electricity is charged by the 'unit'. A 'unit' is one kilowatt-hour (kWh).

The pricing details shown relate to Synergy customers connected to the South West Interconnected System (SWIS), covering the area from Kalbarri in the North, down to Albany in the South and East to Kalgoorlie. For other areas of Western Australia outside of the SWIS please contact Horizon Power.

The supply charge is the daily fixed charge element of your tariff which applies irrespective of how much electricity you consume.


To be eligible for the EV Home Plan, you will need to have a compatible meter installed or an existing meter reprogrammed. Meter installation and programming charges may apply and are stated above for both existing and new homes. Synergy's EV Home Plan compatible meter is not transferable to any other property. Synergy's EV Home Plan compatible meter always remains the property of the network operator, Western Power.

New Home Meter Prices apply when you are building a new home and electricity is not connected.

^^ Free monthly kilometres

The calculation of the free monthly kilometres is based on the average of the estimated km/kWh of seven electric vehicles available for purchase in Australia. This is an estimate only and the actual kilometres travelled on 10 units of electricity may vary.

EV Home Plan FAQs

Want to learn more about Synergy's EV Home Plan? Take a look at our helpful and comprehensive list of FAQs.

Are EVs really the future?

It certainly looks like it! Volvo is switching to EVs only from 2019 and some countries in the world have announced they will be banning petrol cars at some point in the future. In Norway, petrol cars could be banned as early as 2025.

According to a white paper from Advisian, cited on the Electric Vehicles Council website, “the benefits EVs offer consumers will be the main reason for their uptake and we can expect more than four million EVs on Australian roads by 2035.”

In the coming years, we’re likely to see the price of batteries drop and the number of models available in Australia sky-rocket. It’s also likely that more government and industry support will encourage more drivers to choose EVs by offering rebates, special tariffs and better infrastructure.

Can I sign up for the EV Home Plan if I am renting my property?

Yes. Although we recommend you check with your landlord before changing over the meter.

Do EVs cost more than other cars?

Yes at the moment anyway if you compare the upfront cost. When you compare the purchase price of an EV against a similar model of petrol-fuelled car, the electric version will generally cost more. This is likely to change over the coming years as car and battery companies scale up their production, improve their efficiencies and increase competition in the growing EV market. EV costs forecast to hit parity with combustion powered equivalents by 2023*.

The good news is that the running costs of an EV are generally a lot less than petrol cars. Your EV doesn’t need an oil change and a lot of other maintenance that a petrol or diesel engine needs. Charging at public stations is often free or there’s just a small fee involved. Charging at home could cost you less if you take advantage of our EV tariff and renewable energy options over the longer term.

How far can an EV drive?

According to the Electric Vehicle Council, the average distance an EV can drive on one charge (based on the models currently available in Australia) is more than five hours, non-stop. That’s more than most of us need to drive around in one day.

Every model has a different driving range, from around 130km for one charge to more than 600km in one charge for some of the luxury models. It’s getting even easier to charge your EV in Perth with more charging stations popping up around our metro and regional areas. It’s also good to remember that your car is probably parked for a lot more hours than it is actually driving, which gives you plenty of time to top up your EV’s battery charge.

How long does it take to charge an electric vehicle?

Charging time depends on the model of EV you choose. For most EVs, you could expect that your car would be charged to at least 80% (the ideal battery capacity) if you charged it overnight.

For topping up your battery on the road, DC fast chargers or super chargers are the quickest option. Depending on your model, these could give you a boost of over 250km in just half an hour or longer if you have more time to spare*.

*Based on data provided on

My vehicle is electric but I don’t need to plug it in. Am I eligible?

No. If you own a hybrid electric car,  i.e. with an Internal Combustion Engine which produces electricity (like the Toyota Prius), then you are not eligible for the Electric Vehicle Home Plan tariff. Only residential customers with vehicles which plug into an electricity socket are eligible.

Why do I need a time of use meter to access the EV Home Plan?

The EV Home Plan is a time of use product. A time of use meter records both the amount of energy and what time of day the electricity is used. The rate applicable during that time period is then charged.

Why do I need to apply to renew for the EV Home Plan annually?
As our EV Home Plan is only for Synergy residential customers who own an eligible EV, we need to annually review your Department of Transport registration details. We will contact you with instructions when the time comes to renew.
Why do I need to provide my electric vehicle registration details for the application?
Synergy EV Home Plan tariff Synergy EV Home Plan is available for residential customers who have a plug in Electric Vehicle registered at your premises with the Western Australian Department of Transport, with the name and address on the vehicle registration matching the name and address on your Synergy customer account.
