Amber Electric With a Home Battery and VPPs in NSW: How Wholesale Pricing Works, Sigenergy and GoodWe Compatibility, Risks and How to Decide

Checked and updated by our licensed electricians: October 2026

Amber Electric is the retailer battery owners ask us about most. Instead of a fixed rate it passes the wholesale market price through every half hour, and its SmartShift software runs your battery against that price, buying cheap midday power and selling into the evening peak. For a home with a controllable battery it can be a very good fit; for a home without one it usually is not, and for anyone who wants a bill that never surprises them a fixed virtual power plant or a plain time-of-use plan is the calmer choice. This guide, written by the local electricians who install Sigenergy and GoodWe batteries, explains how the pricing works, what sits underneath it on the Essential Energy network, how SmartShift behaves (including before a storm), which batteries are on Amber’s list as at October 2026, the real risks, the fixed VPPs in NSW that accept our batteries, the NSW incentive for joining one, and how to decide. We refer our customers directly to Amber; we do not sell electricity plans and we show no savings figures, because nobody can promise them.

Is Amber, a fixed VPP or neither right for your battery? Checker

Six taps: your battery brand, your solar, how you feel about a moving price, how much backup matters, your internet and whether anyone at home relies on life-support equipment. The result shows on screen straight away with the points that apply to you; sending it to your phone is optional.

What Amber Electric is

Amber Electric Pty Ltd is an authorised electricity retailer available in NSW, the ACT, Victoria, South Australia and south-east Queensland (some postcodes are not serviced, so the first step is always its postcode check). The model is simple to describe: you pay what Amber pays. Your usage is charged at the wholesale market price for each half hour, plus the network charges Essential Energy sets for every retailer, metering, environmental costs and a small hedging charge, all passed through at cost. Amber’s income is a flat subscription, $25 a month at October 2026, and it says it takes no cut of what your exports earn. Your solar exports are paid the wholesale price at the moment they happen. There is no lock-in contract.

Two things follow from that. First, your bill moves with the market: a cold still week in June or a heatwave in February costs more than a mild sunny month. Second, the people who do well are the ones who can move their usage and, above all, the ones with a battery that software can steer, which is why Amber built SmartShift.

How wholesale pricing works, half hour by half hour

Every five minutes the market operator settles a price for electricity in NSW, and retailers like Amber pay the half-hourly result for their customers’ usage. On a normal day it has a shape you can set a clock by: cheapest in the middle of the day when rooftop solar floods the grid (Amber’s own pages say usually 11am to 3pm), rising sharply as the sun drops and people get home, highest around 5pm to 8pm, then easing overnight. Two extremes matter for a battery owner:

• Negative prices. On sunny spring weekends there is so much solar that the wholesale price goes below zero for a few hours: generators are paying to export. On Amber, exporting then costs you a little, so a battery should be charging, not exporting, and solar can be curtailed. Amber does this automatically for compatible systems.
• Price spikes. When a big generator trips, a heatwave bites or wind drops on a cold evening, the price can jump to several dollars a kWh for a half hour or two, and in 2026-27 the market cap is about $23.20 a kWh before GST. Amber does not cap it (it says the big retailers cap it only by charging everyone more all year), it adds a Price Protection Hedging charge to every kWh instead, and it promises that averaged over a year your usage will not cost more than the rates in its published fact sheets, or it refunds the difference. For a home with a charged battery a spike is the best hour of the year: SmartShift sells into it. For a home without one, it is the worst.

Amber sends app and text alerts before expected spikes. SolarQuotes’ long-running reviews of Amber, written by a battery owner, describe exactly this pattern: lower bills over a year, a single spike day that paid about $100 in exports, and the odd month that stung when the battery misbehaved. Your version depends on your roof, your battery and your habits, and we will not put a number on it.

Under the wholesale price: the Essential Energy network tariff

Roughly half of a NSW power bill is not energy at all but the network charge for the poles and wires, and on Amber it is passed through exactly as Essential Energy sets it. Every home with a smart meter in our region now sits on Essential Energy’s residential time-of-use network tariff, which it calls the Sun Soaker. The network components for 2026-27 (before GST, excluding Amber’s wholesale energy, hedging and other charges) as reproduced from Essential Energy’s schedule:

Read it as a battery owner and the plan writes itself: the network wants you to soak up power between 10am and 3pm and to export between 5pm and 8pm, and it pays an extra 11.72 cents on top of the wholesale price for every kWh you export in that window. A SmartShift-run battery does both. The export charge above 7.5 kWh a day at midday is small but real, and it is another reason a battery that stores the midday surplus beats a bigger inverter that dumps it. These are network components only; your retailer, Amber included, adds the energy, metering and its own charges on top, and publishes the total in its Energy Fact Sheet. More on tariffs in time-of-use and feed-in tariffs with solar and a battery.

SmartShift: how Amber runs your battery

SmartShift is Amber’s battery automation. Every five minutes it forecasts your solar, your household usage and the wholesale price over the coming hours, works out the cheapest plan and tells the battery what to do: charge from the panels or the grid when power is cheap, hold, discharge to the house in the evening, or export when the price is high enough to be worth it. When prices are flat it leaves the battery in plain self-consumption. Because it works on forecasts it is sometimes wrong in hindsight, and Amber says so.

• Reserve. SmartShift never discharges to the grid below 25 per cent (a fleet-wide limit), and it always respects the minimum reserve you set in your battery maker’s app; if yours is 30 per cent, that is the floor. Below 25 per cent your home can still use the battery itself down to your reserve.
• Manual control. In the Amber app you can tell the battery to Dispatch (sell now, in a spike), Charge (top up before a cold evening or a storm) or Preserve (hold what it has) for 30, 60 or 90 minutes; commands take three to five minutes to act.
• Blackouts. In an outage the battery drops into backup mode on its own and Amber can no longer talk to it, so backup works as your installer set it. The risk is before the outage: SmartShift does not know a storm is coming and may have sold energy that morning. Amber’s own advice is to raise the minimum reserve or, when a warning is out, charge to full and switch SmartShift off until it passes.
• Your app changes. On a Sigenergy system the operating mode in the mySigen app is locked to VPP mode while Amber is in control; to change modes Amber has to release the system. GoodWe owners authorise Amber to talk to the inverter and must leave any other VPP first.

Sigenergy, GoodWe, Sungrow, Tesla and SolaX: who is compatible

Amber publishes a compatibility list and a checker; the list below is read from that list (updated 23 September 2026) and from GoodWe’s announcement (10 October 2026). Lists change, so the checker is the final word.

Both batteries we install, Sigenergy and GoodWe, are on the list, and every battery we install is VPP-capable as the federal rebate requires. We set the export limit and the controls on install day the way Amber’s enrolment guide asks, so joining later is a form in the app, not a service call.

The risks, honestly

• Bill variability. Some months will be higher than a fixed plan, and you will not know in advance. Amber’s yearly averaging promise limits the damage over twelve months, not in a single bill.
• Price spikes without a charged battery. A spike lands during the evening peak, exactly when a small or empty battery has run out. The fix is a battery sized to your evening, not a bigger inverter.
• Forecast errors. SmartShift plans on forecasts of weather, usage and prices that are never perfect. SolarQuotes’ reviewer documented odd decisions and firmware problems in year one; the overall result was still lower bills, but it was not hands-off.
• Backup left low. Covered above: raise the reserve in storm season and pause the automation when a warning is out. After ex-Tropical Cyclone Alfred in March 2025 (the NSW Government says 84,000 homes and businesses across northern NSW lost power, Essential Energy’s count peaked at about 42,600 on 8 March, and some hinterland homes waited a week) this is not a theoretical point in the Northern Rivers.
• Battery cycling and warranty. A battery that is traded harder cycles more. Our makers warrant on years and on energy throughput; read the warranty document for any wording about third-party control before you join anything, and ask the retailer in writing.
• Internet. Amber and every VPP control the battery over the internet. Patchy connections mean missed plans; some fixed VPPs will not accept the site.
• Feed-in on sunny days. The wholesale price your midday exports earn is low and sometimes negative; Amber suits homes that store the midday surplus, not homes that export most of it.
• It is not for everyone. If the idea of checking an app before a heatwave annoys you, a fixed VPP or a plain time-of-use plan will make you happier. Amber has no lock-in, so trying it is cheap; leaving a fixed VPP usually needs a few weeks’ notice.

Fixed VPPs in NSW that take Sigenergy or GoodWe

A fixed VPP pays you a set amount (a sign-up credit, monthly credits, or dollars per kWh when it calls your battery) in exchange for using part of your battery a few dozen times a year, keeping a reserve for you. The table is read from the SolarQuotes VPP comparison table (updated 3 August 2026) and the retailers’ own lists; terms move every few months, so confirm before you sign.

Our standing advice is unchanged from should I join a virtual power plant?: joining is optional, read what is reserved for backup, check the warranty wording, and remember you can only be in one VPP at a time.

The NSW payment for joining a VPP

Under the NSW Peak Demand Reduction Scheme, connecting an eligible home battery to a VPP creates certificates that an accredited provider sells on the market and passes most of the value back to you as an upfront payment through the VPP. The rules (NSW fact sheets, August 2026): usable capacity above 2 kWh and up to 50 kWh, counted up to 28 kWh; the battery on the Clean Energy Council approved list when it joins; residential premises in NSW with no registered life-support equipment; the account holder signs the VPP contract; once per connection point; from 1 July 2026 the nomination form can be completed within 90 days of joining and solar is no longer required. The amount is not fixed: it depends on the certificate price and the provider’s cut. Amber’s own estimate for a 28 kWh or larger battery joining SmartShift is up to about $1,015 at October 2026, set and paid by its certificate provider, and SolarQuotes reckons households keep roughly 60 per cent of certificate value across the schemes. A second payment exists for batteries that stay in or rejoin a VPP after three years. This is separate from the federal Cheaper Home Batteries rebate, which we build into every design: who qualifies and how the rebate is claimed and your rebates in October 2026.

Amber vs a fixed VPP vs a plain time-of-use plan

How to decide

1. Battery first. None of this works without a battery that software can control and your roof can fill. Size it from your bills: what size battery do I need? and the Northern Rivers home battery buyer’s guide.
2. Ask yourself the honest question. Will you enjoy watching the price, or resent it? Amber is for the first group.
3. Check compatibility and postcode on Amber’s checker, or the fixed VPP’s battery list, for your exact model.
4. Set your backup reserve in the battery app before any automation starts, higher in storm season, and learn how to pause the automation.
5. Read the fact sheet and the warranty for the Essential Energy network plan and for any wording on third-party control.
6. Try the low-commitment option first. Amber has no lock-in; most fixed VPPs need weeks of notice. Give any plan a full season, including a winter, before judging it.
7. Claim the NSW VPP payment once, through whichever program you join; it cannot be claimed twice for the same connection.

What we do, and what we do not

We are a Northern Rivers electrical contractor. We design and install the solar and the battery (Sigenergy as the premium option, GoodWe ESA as the mid-tier), set it up VPP-capable with the export limit and controls the way Amber’s enrolment guide asks, and show you the backup reserve setting at handover. If you want Amber, we refer you to Amber directly and the account is yours with them; we do not sell electricity plans, we are not paid by any retailer to recommend one, and we do not quote what you will pay or earn. Our agents and our team do not discuss prices or plans by text; a real conversation about your bills is a free 15-minute call with our head electrician.

Questions we get asked

How does Amber Electric work with a home battery?

Amber is an electricity retailer that passes the wholesale market price through to you, changing every 30 minutes, for a subscription of $25 a month (Amber’s published figure, October 2026) instead of a fixed rate. Its SmartShift software then runs your battery against that price: it forecasts your solar, your usage and the market every five minutes, charges the battery when power is cheap (usually the middle of the day) and discharges to your home or exports to the grid when it is dear (usually the evening). You keep a minimum reserve for blackouts, and you can take manual control in the Amber app. We refer our customers directly to Amber; the account is yours with them.

Are Sigenergy and GoodWe batteries compatible with Amber SmartShift?

Yes, both, as at October 2026. Amber’s compatibility list says every Sigenergy inverter and battery that has a Sigen Gateway or Sigen Sensor works with SmartShift, and GoodWe’s ESA series was added to the public list on 10 October 2026 after a beta of more than 350 homes. Sungrow and Tesla Powerwall are also listed (Sungrow with set-up conditions). SolaX is not on Amber’s list; SolaX owners can look at the fixed VPPs that accept it instead. Always run your model through Amber’s own compatibility checker before you sign.

What happens to my blackout backup if Amber is controlling my battery?

In an outage the battery drops into backup mode on its own and Amber can no longer send it commands, so backup still works. The catch is beforehand: SmartShift does not know a storm is coming and may have sold energy earlier in the day, leaving the battery lower than you would like when the lines come down. SmartShift never discharges to the grid below 25 per cent, and it always respects the minimum reserve you set in your battery’s own app, so raise that reserve in storm season or, when a warning is out, charge to full in the app and switch the automation off until it passes.

Can my bill go up with Amber?

Yes, in a given month it can. The wholesale price is uncapped by Amber: the market cap for 2026-27 is about $23.20 per kWh before GST (set by the market rules, not Amber), and spikes into the dollars per kWh happen a handful of times a year, more in a tight market. A battery turns those spikes into export income rather than a cost, which is the whole point, but a home without a battery, or with a battery that is empty at the wrong moment, pays them. Amber adds a hedging charge to every kWh and promises that, averaged over a year, your usage never costs more than the rates in its published fact sheets, or it refunds the difference. No one, including us, can tell you what you will pay or earn: it depends on the weather, the market and your habits.

What is a virtual power plant and do I have to join one?

A VPP is a fleet of home batteries that a retailer or operator can call on together, like one big power station. In return you get a sign-up credit, a monthly credit or a payment per kWh when they use your battery. The federal Cheaper Home Batteries rebate only requires that your battery is capable of joining a VPP; joining is optional, and you can leave most of them with a few weeks’ notice. Amber is a different animal: rather than paying you a fixed amount to borrow your battery, it exposes you to the real market and uses your battery to profit from it.

Which VPPs in NSW accept Sigenergy or GoodWe batteries?

For Sigenergy, the SolarQuotes VPP comparison table (updated 3 August 2026) lists AGL, ENGIE, Globird, Plico and EnergyAustralia’s Battery Ease, and Amber through its own compatibility list; Origin Loop’s compatibility list also names Sigenergy. For GoodWe, Amber (ESA series) and EnergyAustralia are listed, and Origin Loop has accepted GoodWe in the past. Lists change every few months, so confirm your exact model with the retailer before you switch.

Is there a NSW payment for joining a VPP?

Yes. Under the NSW Peak Demand Reduction Scheme, connecting an eligible home battery (2 to 50 kWh usable, counted up to 28 kWh) to a VPP creates certificates that an accredited provider sells and passes most of the value back to you as an upfront payment through the VPP. Amber’s estimate for a 28 kWh or larger battery is up to about $1,015 (October 2026), set and paid by the certificate provider, not fixed. Since 1 July 2026 the paperwork can be completed within 90 days of joining, and solar is no longer required. The battery must be on the Clean Energy Council approved list and the home must not have life-support equipment.

Does Amber suit a home without a battery?

Rarely in our experience, and SolarQuotes has said the same since 2018. Without storage you have no way to move your usage out of the evening peak or to profit from spikes, and the wholesale feed-in rate for midday solar is low. Amber’s own help pages say its battery customers are the ones who do well. If you want Amber, size the battery first.

What does Sun Connect Solar do about Amber?

We design and install the solar and the battery (Sigenergy or GoodWe), set it up so it is VPP-capable as the rebate requires, make sure the export limit and the controls are set the way Amber’s enrolment guide needs, and refer you directly to Amber if you want to join. We are electricians, not a retailer: we do not sell electricity plans, we do not quote what you will pay or earn, and whether you choose Amber, a fixed VPP or a plain time-of-use plan is your call. The account is yours with the retailer you pick.
