AGL VPP Review 2026: Bring Your Own Battery Plan Explained

The AGL VPP is a Bring Your Own Battery programme that pays you credits when AGL remotely discharges your home battery during peak grid demand. You stay on an AGL electricity plan, your compatible battery joins AGL’s virtual power plant network, and you earn between $200 and $600 per year depending on your battery size and state. It is one of the simpler VPP options in Australia, but it comes with trade-offs worth understanding before you sign up.

AGL acquired Tesla’s South Australian Virtual Power Plant in 2023, absorbing thousands of Powerwall owners into its network. That move made AGL one of the largest residential VPP operators in the country. Since then, AGL has expanded the programme beyond Tesla hardware to include batteries from sonnen, Alpha ESS, Sungrow, and BYD.

If you are unfamiliar with how virtual power plants work at a technical level, our VPP explainer covers the mechanics in detail.

How the AGL VPP Works

AGL’s model is straightforward. You own a home battery. You sign up to the AGL VPP through your AGL account. AGL connects to your battery’s inverter via the internet and monitors grid conditions in real time. When wholesale electricity prices spike or the grid is under stress, AGL sends a dispatch signal to your battery. Your battery then exports stored energy to the grid on AGL’s behalf.

You earn credits on your electricity bill for every kilowatt-hour exported during these events. The credits are applied automatically. You do not need to do anything during a dispatch event. The whole process is hands-off once you are enrolled.

A typical dispatch event lasts between 30 minutes and two hours. Most occur on hot weekday afternoons in summer when air conditioning drives demand to its peak. AGL runs between 10 and 30 events per year for most participants, though the exact number varies by state and season.

The Australian Energy Market Operator (AEMO) recorded VPP capacity exceeding 900 MW across the National Electricity Market by early 2026, with AGL’s fleet representing a significant share of that total (AEMO, 2026). The growth reflects a broader trend. The Clean Energy Regulator confirmed over 500,000 cumulative home battery installations in Australia by the end of 2025 (Clean Energy Regulator, 2025).

AGL VPP Compatible Batteries

Not every battery works with the AGL VPP. AGL maintains a specific compatibility list, and it has grown considerably since the programme launched. As of June 2026, the following brands and models are supported:

Tesla Powerwall 2 and Powerwall 3. The most widely supported battery in the AGL VPP. This is a legacy of AGL’s acquisition of the Tesla VPP in South Australia. Powerwall systems integrate smoothly because Tesla’s API gives AGL direct control over dispatch.

sonnen. The sonnenBatterie range is supported. sonnen batteries use their own cloud platform for VPP communication, which AGL connects to via API.

Alpha ESS. Select Alpha ESS models including the SMILE5 are compatible. Alpha ESS has been expanding its VPP integrations across multiple providers.

Sungrow. The Sungrow SBR series works with the AGL VPP in most states. Sungrow batteries require a compatible Sungrow hybrid inverter.

BYD. The BYD Battery-Box HVM and HVS ranges are supported when paired with a compatible inverter from Fronius, GoodWe, or SMA.

If your battery is not on this list, you cannot join. That rules out brands like Enphase, GoodWe (as a standalone battery without BYD), and several smaller manufacturers. Before committing, check the current compatibility list on the AGL VPP page.

States Where the AGL VPP Is Available

AGL operates its VPP across four states:

• New South Wales - available but fewer dispatch events due to more stable wholesale pricing
• Victoria - strong VPP activity, especially during summer heatwaves
• South Australia - the most active state for VPP dispatch, with higher wholesale price volatility
• Queensland - available with moderate dispatch frequency

South Australia consistently delivers the highest earnings. The state’s high renewable penetration and relatively small grid size create frequent price spikes that trigger VPP events. Victoria follows closely. NSW participants earn less because wholesale prices are generally lower and more stable.

Tasmania, Western Australia, and the ACT are not supported. WA operates on a separate electricity market (the Wholesale Electricity Market), which is not part of the National Electricity Market that AGL’s VPP participates in.

AGL VPP Rates and Earnings

AGL pays VPP credits as a flat rate per kilowatt-hour exported during dispatch events. The exact rate varies by state and by the wholesale price at the time of the event. AGL does not pass through the full wholesale price to you. Instead, you receive a fixed credit that AGL sets.

Typical annual earnings break down roughly as follows:

State	Battery Size	Estimated Annual Earnings
South Australia	10–13.5 kWh	$350–$600
Victoria	10–13.5 kWh	$250–$450
Queensland	10–13.5 kWh	$200–$350
New South Wales	10–13.5 kWh	$150–$300

These are estimates based on 2025–2026 dispatch patterns. Your actual return depends on how many events AGL calls, how much energy your battery can export per event, and whether your battery is fully charged when the event starts. A 13.5 kWh Powerwall 3 with a 20% reserve exports more per event than a 10 kWh BYD HVS with the same reserve.

The numbers are modest compared to wholesale pass-through models like Amber Electric, which can pay significantly more during extreme price spikes. But AGL’s flat credit approach is predictable. You know roughly what you will earn without watching wholesale markets.

AGL VPP Electricity Rates vs Standard AGL Plans

Joining the VPP does not automatically put you on a cheaper electricity plan. Your underlying AGL electricity rates stay on whatever plan you are enrolled in. AGL offers several residential plans, and VPP participants can be on any of them.

That said, AGL sometimes offers VPP-specific plan bundles with marginally better rates to attract and retain battery owners. These change frequently. The key thing to check is your overall electricity cost, not just the VPP credits. A VPP earning you $300 per year is worth nothing if AGL’s underlying rates cost you $200 more than a competitor.

Compare the total annual cost: AGL electricity charges minus solar feed-in minus VPP credits. Then stack that against what you would pay on another retailer’s plan (including any VPP they offer). The maths matters more than the marketing.

How Dispatch Events Work in Practice

When AGL triggers a dispatch event, your battery receives an instruction through its internet-connected inverter. The battery begins exporting energy to the grid within seconds. You will likely not notice it happening.

AGL lets you set a minimum battery reserve. Most people choose 20%. That means during a dispatch event, AGL can drain your battery down to 20% charge but no further. If you want more blackout protection, set a higher reserve. If you want maximum earnings, lower it. The trade-off is yours.

During the event, you cannot use the dispatched energy for your own home. Your home draws from the grid instead. If your solar panels are producing at the time, some of that solar output may go to the grid as well. After the event ends, your battery recharges from solar the following day or from the grid overnight if needed.

AGL sends notifications before and after events through its app. You can see how much energy was exported and what credits you earned. The system is transparent enough, though it lacks the real-time granularity that providers like Amber Electric offer.

Battery Wear and the AGL VPP

Every charge cycle wears a battery slightly. VPP events add extra cycles on top of your normal daily solar self-consumption cycling. The question is whether the additional wear matters.

For most participants, it does not. AGL’s 10 to 30 events per year add roughly 10 to 30 partial cycles annually. A typical home battery does 300 to 365 full cycles per year from daily solar use. The VPP contribution is about 3 to 8% extra cycling. Modern lithium iron phosphate (LFP) batteries are rated for 6,000 or more cycles. The maths works out comfortably within warranty.

The Australian Energy Market Commission noted in its 2025 review of distributed energy resources that VPP participation at current dispatch levels does not materially reduce battery lifespan for systems using LFP chemistry (AEMC, 2025). That finding aligns with what battery manufacturers themselves state.

If you own an older NMC (nickel manganese cobalt) battery with fewer rated cycles, the calculus is tighter. But most batteries sold in Australia since 2023 use LFP chemistry.

The Tesla VPP Acquisition: What Changed

AGL acquired Tesla’s South Australian VPP programme in late 2023. Before that, Tesla ran its own VPP directly, enrolling Powerwall owners through the Tesla app and paying them from Tesla’s wholesale market revenue.

Under AGL’s ownership, the programme transitioned to AGL’s retail framework. Powerwall owners in SA who were previously on the Tesla VPP were migrated to AGL’s Bring Your Own Battery plan. The core mechanics remained similar: battery gets dispatched, owner earns credits. But the billing and credits now flow through AGL’s systems rather than Tesla’s.

For participants, the main change was needing to be (or become) an AGL electricity customer. Some former Tesla VPP members reported lower per-event earnings under AGL compared to the Tesla-operated programme, particularly during extreme wholesale price events where Tesla had passed through a larger share of revenue.

AGL gained a large, proven fleet of grid-connected batteries. Tesla stepped back from direct retail energy operations in Australia. The Powerwalls still respond to dispatch signals through Tesla’s Gateway hardware, but AGL controls when and how often those signals are sent.

Who the AGL VPP Suits

The AGL VPP is a good fit if you tick these boxes:

• You already have an AGL electricity plan (or are willing to switch to one)
• You own a compatible battery from the list above
• You want passive, set-and-forget VPP income without monitoring wholesale markets
• You are comfortable with AGL controlling your battery during 10 to 30 events per year
• You value simplicity over maximising every dollar

It suits existing AGL customers who bought a battery for solar self-consumption and want to earn a bit extra from it. The sign-up process is simple. The credits appear on your bill. You do not need to think about it day to day.

Downsides of the AGL VPP

Limited battery compatibility. If you own an Enphase, GoodWe, or less common battery brand, you are locked out. The compatibility list is narrower than providers like Amber Electric, which supports most batteries with API-accessible inverters.

Must be on AGL electricity. You cannot join the VPP while retaining another retailer. This limits your ability to shop for the cheapest electricity rates. AGL’s plans are competitive but not always the cheapest in every market.

Loss of control during events. When AGL dispatches your battery, you lose access to that stored energy for the duration of the event. If a blackout occurs during a dispatch event while your battery is at its reserve level, you have limited backup capacity.

Lower earnings ceiling. AGL’s flat credit model caps your upside. On a 40-degree February afternoon when wholesale prices hit $15,000 per megawatt-hour, Amber Electric participants might earn $20 to $50 from a single event. AGL participants earn their standard credit rate regardless. The flip side is that AGL’s approach is more predictable.

No FCAS revenue sharing. Some VPP providers share revenue from frequency control ancillary services (FCAS) markets with participants. AGL does not currently pass through any FCAS earnings to residential VPP members.
