Choosing the optimal electricity plan for a home equipped with solar panels, a battery, and an electric vehicle (EV) in Australia is no longer about finding the cheapest rate per kilowatt-hour. In 2026, it’s about strategically leveraging time-of-use tariffs, generous EV charging windows, high feed-in tariffs (FiTs), and Virtual Power Plant (VPP) participation to maximise self-consumption and earn credits for grid support. The right plan can slash your annual energy bills by hundreds, if not thousands, of dollars.
The Evolving Energy Landscape for Solar, Battery & EV Homes in 2026
Australia’s energy market is rapidly transforming. The Default Market Offer (DMO) and Victorian Default Offer (VDO) for FY26/27, effective from 1 July 2026, reflect these shifts. For most households on standing offers, DMO prices in NSW and South East Queensland have fallen by 3.4% to 7.2% for flat rates, and up to 10.7% for time-of-use (ToU) tariffs. Victoria’s VDO has seen residential prices decrease by an average of 5%, saving households around $84 annually. However, South Australian residential flat-rate DMO prices saw a modest increase of 1.4%.
Crucially, the new Solar Sharer Offer (SSO), introduced as part of DMO reforms from 1 July 2026, provides eligible smart meter households in DMO regions (NSW, SA, SE QLD) with three hours of free power during the middle of the day. This directly benefits solar homes, allowing for free charging of EVs or batteries when solar generation is abundant, even if the home doesn’t have its own solar panels.
Wholesale electricity prices in the National Electricity Market (NEM) also saw significant drops in Q2 2026, falling by 47% from the previous year to an average of $74/MWh. This reduction was driven by record renewable generation (42.1% share) and increased battery storage, with batteries frequently setting prices at lower averages of $107/MWh. These wholesale savings are beginning to flow through to retail offers, making it an opportune time to reassess your energy plan.
Key Factors to Consider When Choosing Your Plan
1. Maximising Your Solar Feed-in Tariff (FiT)
While FiTs have generally declined, typically ranging from 3-10 cents per kilowatt-hour (c/kWh) in 2026, they remain a component of your savings. However, the focus should be on self-consumption – using your generated solar power directly or storing it in your battery – rather than exporting it for a low FiT. Some retailers still offer competitive FiTs, often with tiered structures or daily caps:
| Retailer (Example State) | Plan Type | FiT Rate (Example) | Conditions/Notes |
|---|---|---|---|
| Flow Power (VIC) | Variable | Up to 45 c/kWh | High but often with specific market-linked conditions |
| Origin Energy (NSW) | Solar Boost | 10-12 c/kWh | Applies to first ~8 kWh/day export, then standard FiT |
| AGL (NSW) | Solar Savers | ~8 c/kWh | Applies to first 10 kWh/day export, then ~4 c/kWh |
| EnergyAustralia (NSW) | Solar Booster FiT | ~12.2 c/kWh | Fixed term, eligible customers; or tiered for first ~10 kWh/day |
It’s crucial to understand that a high headline FiT might come with lower overall usage rates or daily supply charges, or conversely, a high FiT could be paired with higher usage rates. Always compare the total estimated annual cost of a plan, not just the FiT.

2. Optimising EV Charging Costs
EV owners can achieve significant savings, potentially up to $1,000 per year, by utilising specialised EV electricity plans. These plans offer super off-peak rates for charging, typically between midnight and 6 am, or even free charging windows during the day when solar generation is high.
| Retailer | Plan Name (Example) | Off-peak Charging Rate | Charging Window (Example) | Notes |
|---|---|---|---|---|
| OVO Energy | The EV Plan | 4.5 c/kWh | 12 am - 6 am | Also offers free electricity 11 am - 2 pm |
| AGL | Night Saver EV Energy Plan | 8 c/kWh | 12 am - 6 am | Requires digital meter, whole home electricity |
| Engie | EV Night Saver | 6 c/kWh | 12 am - 6 am | Whole home electricity |
| Powershop | EV Night | 5 c/kWh | 12 am - 4 am | |
| Globird | Free Lunch | Free | 12 pm - 2 pm |
Charging your EV during these windows, or directly from your rooftop solar, can reduce the effective cost of charging to near zero. A home charging wall box, such as models from Zappi or Wallbox, typically costs $800 to $2,000 plus $400-$900 for installation, and allows for smart scheduling to maximise these off-peak or solar-powered periods.

3. Leveraging Home Batteries with Virtual Power Plants (VPPs)
Home batteries are not just for blackout protection; they are an asset that can earn you money through VPPs. In 2026, joining a VPP can earn you $100 to over $1,000 annually, beyond your solar savings. VPPs allow energy retailers to draw power from or charge your battery during peak demand or high renewable generation periods, stabilising the grid and rewarding you.
“VPP capacity reached 900 MW across the National Electricity Market by Q1 2026, up from approximately 350 MW in early 2024.”
Key VPP Programs and Incentives (2026):
- Federal Cheaper Home Batteries Program: Offers an upfront discount of roughly 30% on eligible batteries, equating to approximately $272 per usable kWh for the first 14 kWh. This applies nationwide.
- NSW: The Peak Demand Reduction Scheme (PDRS) offers an incentive for connecting your battery to an approved VPP, typically around $40 per usable kWh (e.g., $400-$550 for a typical home battery). From 1 July 2026, batteries up to 50 kWh are eligible.
- Victoria: Offers interest-free loans up to $8,800 via the Solar Victoria Battery Loan, and a rebate of up to $2,950 for households with existing solar.
- South Australia: While its original Home Battery Scheme has closed, SA offers a Retailer Energy Productivity Scheme (REPS) VPP incentive of up to $2,050 for joining approved VPPs, though funding is limited for general households as of May 2026.
- ACT: Offers interest-free loans up to $20,000 (raised from $15,000 on 1 July 2026) through the Sustainable Household Scheme.
Leading VPP providers include Tesla Energy Plan (via Energy Locals), known for highest returns in SA, Amber Electric (broad compatibility), and AGL VPP (structured annual credits). Always check battery compatibility and contract terms before joining. For more information, read our guide on Maximise Your Home Battery Savings: Earn $1,000+ Annually with a VPP in 2026.
4. Time-of-Use (ToU) Tariffs and Demand Charges
Most solar, battery, and EV owners will benefit from Time-of-Use (ToU) tariffs over flat-rate plans. ToU tariffs charge different rates for electricity based on the time of day (peak, shoulder, off-peak). Your battery can store cheap off-peak power or excess solar to discharge during expensive peak times. While demand charges (penalties for peak instantaneous power draw) are less common for residential customers, they are a factor to be aware of in some networks.
State-Specific Considerations
- New South Wales: Benefits from DMO price reductions for most, PDRS VPP incentives, and a wide choice of EV plans.
- Victoria: Enjoys VDO price drops, generous battery loan/rebate schemes, and competitive FiTs (e.g., Flow Power) and EV plans.
- Queensland (South East): Sees significant DMO price reductions, strong overnight EV charging options, but relies mainly on federal battery incentives.
- South Australia: Experienced a slight DMO increase for flat rates but benefits from VPP incentives (for priority households) and some of the highest VPP returns.
- Western Australia: Synergy offers unique EV Add-On plans and state battery rebates, but has limited retailer competition.
- ACT: Accesses interest-free loans for batteries and benefits from strong FiTs and EV plans from providers like ActewAGL.
Practical Steps to Find Your Best Plan
- Understand Your Usage: Analyse your electricity bills to identify peak usage times, solar export patterns, and EV charging habits. A smart meter is essential for ToU and VPP benefits.
- Utilise Comparison Tools: Use government comparison websites like Energy Made Easy (NSW, QLD, SA, TAS, ACT) and Victorian Energy Compare (VIC). Input your specific usage data for accurate comparisons.
- Prioritise Retailers with Smart Offerings: Look for retailers like AGL, Origin, OVO Energy, Amber Electric, and Powershop who actively cater to solar, battery, and EV owners with specialised tariffs and VPP programs.
- Inquire About VPPs: If you have a battery or are considering one, ask retailers about their VPP programs, incentives, and compatibility with your battery model (e.g., Tesla Powerwall, BYD, Sungrow are generally supported).
- Check for Rebates: Confirm your eligibility for federal and state battery rebates, as these significantly impact the overall economics of your home energy system.
- Review Terms and Conditions: Pay close attention to contract length, exit fees, daily supply charges, and any conditions tied to high FiTs or EV rates.
Bottom Line
For Australian homes with solar, battery storage, and an EV in 2026, the best electricity plan is a dynamic choice that goes beyond a simple low kWh rate. It’s a combination of a Time-of-Use tariff that incentivises off-peak EV charging and battery cycling, a competitive (though not necessarily the highest) feed-in tariff for unavoidable exports, and active Virtual Power Plant participation to earn credits and support grid stability. With DMO/VDO prices stabilising or falling in most regions and new innovations like the Solar Sharer Offer, now is the time to actively compare and switch to a plan that rewards your commitment to sustainable home energy. Don’t settle for a standing offer; proactively engage with the market to maximise your annual savings, potentially reaching over $1,000 per year.
