Synergy EV Add-On · WA only

The four time zones that
change everything

National EV calculators use one average rate. In Perth, the gap between the cheapest and most expensive window is over 45c/kWh. Timing your charge correctly is the biggest lever you have.

Super off-peak Best
9:00 am – 3:00 pm
8.6c/kWh
Best window — perfect for solar surplus or grid charging.
Overnight
11:00 pm – 6:00 am
19.4c/kWh
Set a charge timer — second cheapest option.
Shoulder
6–9 am & 9–11 pm
~29c/kWh
Acceptable if needed — avoid where possible.
Peak Avoid

Never charge during this window — 6× more expensive.
How to activate: Call Synergy to add the EV Add-On to your residential account. Available to all WA homeowners with a registered EV or PHEV. The EV Add-On applies to a separate meter or sub-meter for your charger — your home electricity stays on the standard A1 tariff (~31.4c/kWh flat).

The Perth Advantage

Solar + EV = the ultimate Perth combo

Perth has the highest solar yield of any Australian capital. Pair it with an EV and your fuel bill effectively disappears.

Perth · Solar capital of Australia
Charge your EV for nearly free using your own solar

Perth averages 5.8 peak sun hours per day — the highest of any Australian capital. The Synergy Super Off-Peak window (9am–3pm at 8.6c/kWh) aligns exactly with peak solar production.

Since the Synergy DEBS export rate is only 10c/kWh, it's better to self-consume your solar power than export it. Charging your EV during the day means you're using power you generated — your effective cost approaches zero.

Common questions

Perth EV questions answered

With Synergy's EV Add-On tariff, charging costs as little as 8.6 cents/kWh during Super Off-Peak hours (9am–3pm), or 19.4 cents/kWh overnight (11pm–6am). Perth solar owners who charge from their own panels during the day pay effectively near-zero — making Perth one of the cheapest places in the world to run an EV.
The Synergy EV Add-On applies a separate time-of-use rate to your EV charger: Super Off-Peak 8.6c/kWh (9am–3pm), Overnight 19.4c/kWh (11pm–6am), Shoulder ~29c/kWh (6–9am and 9–11pm), and Peak 53.8c/kWh (3–9pm). Your home electricity stays on the standard flat rate. Call Synergy to activate it once your EV or PHEV is registered.
For most Perth drivers, yes. At current FuelWatch prices (~$2.15/L for ULP91), a typical 10L/100km car costs over $3,000/year in fuel at 14,000km. An equivalent EV charged overnight costs ~$435/year — a saving of ~$2,575 annually. With EVs like the BYD Atto 1 starting under $24,000, payback periods are increasingly attractive. Use the calculator above for your exact numbers.
Yes — and Perth is perfect for this. The Synergy Super Off-Peak window (9am–3pm) aligns exactly with peak solar production. Since Synergy's export rate is only 10c/kWh during this time, it's better to self-consume than export. Solar owners who charge during the day use power they generated, making their effective cost approach zero.
A 7.2kW AC home charger (Type 2) is the standard for Perth homes. At this rate, a 60kWh battery charges from 20% to 80% in about 5 hours — easily overnight. Installation by a licensed Perth electrician typically costs $800–$1,500 including the unit. Exploren and JET Charge both offer supply-and-install packages in WA.
WA's $3,500 ZEV rebate ended in 2023. However, the federal FBT exemption for EVs under the LCT threshold (~$89,332) remains active — a significant benefit for salary sacrifice. The Driving the Nation Fund continues to expand WA's fast-charger network, reducing range anxiety on regional routes.
