[NSW, VIC, SA, QLD] ZeroHero: $0/kWh 11am-2pm, 15¢/kWh FIT for First 15kWh, Avoid Grid Usage 6pm-9pm for $1/Day Credit @ Globird

2210

Extremely popular plan seems to be even better now for those of us with batteries. No need to bind your battery to a VPP either.

The idea is you soak up all the power you can from the grid during the free power window, live off the battery for the rest of the time and schedule your battery to discharge 15kwh during 6pm - 9pm. All of this can be setup from your inverter settings and be set and forget. Mine adjusted to daylight savings itself. No issues. If you get your gas through GloBird you then pay your gas bill with your power credit, so you’ve got free electricity and gas. Not bahhhhd.

The new standard ZEROHERO plan works with any home battery brand and includes these core features:

  • 3 hours of free daily grid charging 11am - 2pm

  • $1/day credit for avoiding grid usage between 6pm-9pm local time

  • 15c/kWh feed-in tariff for battery exports up to 15kWh/day between 6pm-9pm local time (up to $2.25/day)

Personally, I might be an outlier, but I prefer the four4free plan and use that to charge the battery. Happy to pay ~$1.50/day daily service charge, knowing that’s the most I will pay. Means even on cloudy days when using central AC I’m sorted.

FWIW I have a 51kwh battery and 15kw inverter.

Interesting now that FITs are so low for sunny period, the big solar arrays we all got over the last 10 years are a lot less useful, considering as long as you have a large inverter you can just soak up 15kw/hour from the grid.

If anyone doesn’t have a large 50+kwh battery now, I’d suggest getting one before the subsidy for large systems falls off a cliff on 1.05.26. The ROI on our system is about 2.5 years. Pretty amazing.

Since the OG ovo EV plans have finished 11-1pm free. 12am - 6am 8c/akWh, these seem to be the new best options. Until this is grandfathered too.

    The downside to the update is an extra hour required for zero usage (currently 6-8pm)

    • So what’s better about it now?

      • +2

        Slightly more maximum feed in means you can earn slightly more credit each day.

    • But there will always be some usage tight? So it will never be zero?

      • There's a small allowance, but only enough for battery handshakes really.

        Have accidentally gone over it couple times lately, still sorting battery settings

      • Yes, but "Zero" usage is defined by anything less than 0.03kWh per hour.

      • +2

        It depends a bit on the inverter, but mine can easily go over the 0.03kWh when some appliances are on. The oven is the worst as it will pulse on and off to maintain a temperature and while the inverter only takes a second to catch up, when it does that every 20s or so then the import adds up quickly.

      • +1

        I have ours set to feed in at 300w during the zero hero hours to ensure that were don't pull enough from the grid to lose the $1

        • 300 or 30W

          • @Chatbot: definitely don't do 30w feed-in, on sudden high power, your inverter is unlikely fast enough to catch up and that can be real bad.

      • Depends on your usage and battery size. I have 3 Powerwall 3s so this is perfect for me

    • Also as we head towards months with less sun and more cloud/rain, people may be more reliant on their battery, rather than exporting 15kWh in the evening. Thus if you can't export an extra 5kWh compared to the current plan, then it's better to have a smaller zero usage window from 6-8pm.

      • Wouldn't it pay off to feed in 15kw during the high pay window, and then draw 15kw from the grid overnight if needed on a smaller fee?

        • +1

          Curious where you can get less than 15c/kWh for night time usage with this plan? For me in SE QLD it's 33c/kWh

  • +9

    i have a 15kwh inverter and charge my 48kwh battery to full in 3 hours. about 30%-40% goes to Tesla and 20%-40% sell back to the grid, 10%-30% self use.
    I don't pay for electricity and fuel any more, and i get about $1.5 credit every day ($1 from zerohero).

    • +1

      Do you have panels or just get a battery? Im keen to learn more. How much did your set up cost and how long till you make your investment back.

      • +5

        i have a small solar , i think its 3.6kwh. with the 3hour free charging i dont need solar but to be eligible from the rebate you must have solar.
        it will pay back in about 3years. you need to get in before 1 May as the rebate will reduce after.

        • Has the rebet been lower than last year? Because force charge from the grid can be cut off anytime sooner or later, should we replace solar and battery together now? Or it costs the same by installing upgrading the solar later when needed?

  • -3

    I just got a battery installed. I'm already with Amber, so going to stick with SmartShift (just connected last night). Still trying to navigate which plan to go with in the end, but I suspect using Amber with HA is ultimately going to be best.

    • +9

      I've only been with Amber for four months, however in VIC the grid seems too stable for the advetised economics of Amber to work… most I'm in credit per day is 20c.
      11kw PV, 40kw battery

      • Are you with SmartShift? This is why I mentioned HA, because from what I've read you can get good figures if you customise it yourself.

        • +3

          I'm in SA and I've been with amber for a month now. It's pretty disappointing so far. The first week was alright, i think on the best day i made $6, but after that the FIT very rarely went over 15c/kWh, which is not really worth exporting for from battery in my opinion. During the day it's usually negative so no point exporting the solar energy directly either.
          I think I'm gonna switch to flow power soon for the 45c/kWh FIT.

          • @Save-O: Not sure if you can answer, but with FlowPower/Globird is it like SmartShift in that they automatically do this all for you? Or do you have to manually schedule this stuff from your end?

            • @dottjt: Globird has VPP, but it's pointless given their relatively static pricing - just program your battery manually to match their tariff

            • @dottjt: Manual for flow power.

            • @dottjt: Globird is automatic, flower power isn't

          • @Save-O:

            FIT very rarely went over 15c/kWh

            I would guess you were on RTOU tariff then. If you had switched to RESELE tariff there was an additional 12c added to the FIT from 5pm-9pm (that ended april 1) . Plus the 10AM-4PM tariff was lower making negative prices daily, ie. getting paid to charge batteries, run aircons etc.

            • @Bruceflix: Yeah, I did read about the RESELE tarif recently, but as it was too close to April and you can only change tariffs once a year I didn't switch.

              • @Save-O: If you can avoid import during peak there is no disadvantage to RESELE. It is literally cheaper than RTOU except during peak hours which are reduced as well.

            • @Bruceflix: Sorry what’s this - negative pricing??

          • +9

            @Save-O: Also in SA with Amber since last September. I have to get it off my chest… their customer service is awful. It took over a month to get onboarded (they kept blaming Fronius and Tesla, but it was them). A phone recording saying they can't take calls, an email address where you're lucky to get a reply after a week.

            As for energy costs. When the Govt. was giving us the $75 a quarter, that helped.

            But, per month, the Amber modelling just doesn't make sense. $25 per month Amber fee + $1.09 per day usage charge that they pass on, so in a billing month of 30 days that's $57.70 you have to make by selling energy each month JUST to break even.

            Yeah, I only have a 6.6kWh set of panels, a 5.0kWh inverter and Tesla Powerwall 2 battery, and unless there's a spike that lasts longer than 5 minutes, i've got no hope of breaking even. There was one spike in January (I think) where we earned a freakish $152.46 in one day, but the more people that get solar & batteries, those spikes will become rarer.

            Globird looks like the way to go. Amber's SmartShift is dumb as. Its default is to sell power off once the export rate hits 16c per kWh or above. So, it starts selling off all your power, despite predictions that show the export price will be in the 30-40c per kWh range later in the day. It's illogical. I asked Amber to add a slider in the app where we could select what price point WE WANT SmartShift to sell off power at to the grid, but the best response was, program it myself. I'm sure it's possible to do, and even control it via a digital assistant, but I don't possess that knowledge.

            Amber's only good if you've got a huge capacity battery. Then "SmartShifty" can sell off all your power at 16c+ for hours and hours. With only a 14kWh battery (or 13.5), SmartShift basically sells it off when the rates are low, and when they do peak, we don't have any power to sell them (despite making the full 100% capacity of the battery available).

            Amber just seems like a LOT of work for not a lot of reward. Their app is often down, or it'll tell you it has no internet connection. Curtailing doesn't always kick in as it should so there have been days where we've lost 20c or more because of that. Their fanciful rates they quote on the website, well, they may or may not happen. Even when they do hit $1.08 it's for a 5 minute window and SmartShift won't send the command to export until 2 or 3 minutes in. Unless you're chained to the app and control things manually, good luck making a profit from Amber!

            • +1

              @Graffin: Yeah, I gave up oin sartshift after a few days. Slow to act and made stupid decisions. HomeAssistant worked much better but i've just left Amber now as I only went with them to get the SA VPP rebate. Flow and Globird are more predictable and much easier to configure

          • +2

            @Save-O: Amber is all about grid fluctuations these days, mostly in summer and winter. 1 day of shit can keep you in credit for months.

            • @Xizor: Is there a way to automate it better to take advantage of these grid fluctuations though?

              • +1

                @keeperofthegood: Yes it is possible by HA. I have it integrated with dashboards displaying metrics including Amber but i haven't delved into actual automation commands. Others have though.

                Main benefit being quicker action times as Amber's smart shift sending commands is laggy, but other potential benefits too depending on your goal.

      • -4

        Don't waste your time with Amber or Globird. AGL's battery rewards plan is the best one as they pay you 29c/kWh for all exports between 5PM-9PM each day at an average cap of 17.1kWh/day which is as much as $1810/year. All other exports are paid at 4c/kWh and you also get $800-$1000 of credit for staying with them for 12 months. Globird isn't as good.

        • +2

          Can you charge form the grid for free on this plan? Link?

          • @Bellpop: https://www.agl.com.au/residential/energy/compare-plans/batt…

            I can't see free grid ,would be nice otherwise !

            • @cpurn: Starts 1st July with Solar Share.

            • @cpurn: all companies are free grid 3 hours or 4 come 1st July

          • +3

            @Bellpop: Doesn't look like it so if it's rainy you're gonna be eating into your credit just to power things and it'll only be worse in winter with shorter days and more heating requirements. Globird is just simple for those of us who just want to set things up once then forget about it.

        • 25c/kwh peak and 1.5c/kwh off-peak for me in Vic South Eastern .

        • +2

          AGL battery reward only showing 25c/kWh feed-in between 5pm-9pm for me, and it is given as a gift card, not cash payback :(

        • Not a bad plan. Only if you had a free period to charge up the battery!

        • Agreed doesn’t compare if no free grid time?

          • +1

            @Captain Hindsight: Hmm fair enough, if you only have a small solar system and can't charge up your huge battery then the Globird plan still wins. I have 10.5kW of solar panels with a 51.2kWh battery so the AGL plan definitely wins as I'm always charging for free during the day anyway. What they don't tell you is that you also get 4c/kWh for all feed ins between 5PM-9PM in addition to the 25c/kWh gift card you'll be getting. This is basically cash which is even better than electricity credit as you can buy whatever you want with it.

            • +2

              @supersabroso: I moved to AGL battery reward after trying Amber for 2 weeks as I feel Amber it just a gamble where you don't know how much spike rates you will get and what you will be paying at the end of month/quarter.
              With AGL, I can export around 1500kw at 0.29 for each quarter to get $400 gift/cash card, so $1600 a year + $800 credit after completing 1 year, so you can make upto $2400. Yes, they don't have free period during the day, but their chargers are 0.20 cents during the day (excluding peak period).

              I got 42kwh battery with 5kw solar. I mostly use my solar production in my house and to charge my EV. I charge my battery from grid during the day at 0.20c and export it at 0.29c during the peak period. When I don't have to charge my EV, I have enough surplus from the solar to export so don't need to import from the grid on that day.

              So overall in my first quarter, my usage bills was $260 (including all charging from grid + supply charges) and I got $380 gift card for the all the peak time export. So I am $120 surplus after paying for may all house usage, EV charging and supply charges.

              I guess, in winder my usage will be more and I may not have surplus after receiving the gift/cash card for this quarter.
              I see this plan like, whatever my solar produce which I am not using and exporting to grid, I make 0.29 cents, or I buy it from the grid and sell it back to make 0.09 cents, and $800 credit at the end of the year.

        • Only time AGL plan would be good is during summer………..no free hours at AGL yet but it's coming…..October here in Vic

          • @panorama: I think, from July it's coming to NSW as well, but I don't think they will offer it under the "solar reward" plan. If you opt for a high FIT plan, you won't get the free 3hrs electricity.

      • +2

        Wait for winter. I was with Amber 3 years ago, and the worst days where when it was cold, cloudy but still, and had been like that all week. Price would go up to 50c or more.

      • Exactly. Amber doesn't work in VIC if you want to make good profit. Our grid is stable and electricity price isn't too high. Plus you need to curtail a lot during peak generation to avoid negative FIT. Best option is Flow Power. I'm 2 months in and in credit $300+.

        • Won't be stable for too long with another major coal fire plant to be decommissioned in the near future. I'd expect the market to fluctuate pretty rapidly when that occurs, much like SA did/does

        • +1

          @aarick, how is this possible with FlowPower? In VIC it’s $0.35 feed in for two hours at 5kw, but there are still network/service charges. Mind sharing how did you do it? Thanks

    • +7

      You'll end up paying amber money for sure, the time for gambling the system is almost over. During the last summer there were probably 3 or 5 days where spot price were worth it and you could theoretically made around $50-$100 per event, the rest of it was measly 20c or less at night which was not enough to recoup the daily charge Amber impose on you. And that's not counting on Amber's sluggish platform playing with your system (and make you pay for it) for months before becoming usable. And by that time anyone on the other plant is already ahead of you.

      • Fair enough. How does Globird make money then?

        • +3

          They made money from people who doesn't have battery and able to buy less expensive chunk of tariff during peak hours, and also from getting paid for taking energy from grid during noon.

        • They dont. This plan is a clear loss-making plan to grow their customer base. The people above whinging about all the "extra" fees Amber charge are also here, and in all other plans. The difference is you don't see them, and they will recoup them in different ways (or as mentioned, cop deliberate losses over a short term period)

        • +1

          Fair enough. How does Globird make money then?

          My guess is:

          1. Very low to negative prices during off peak (the free period) are increasingly common so when I draw my 20 to 60 kWh during that 3 hour period, they are making some revenue from that.
          2. During peak times, we aren't importing from grid so they avoid losses as the peak price we pay may not always cover actual costs. Maybe this is a cheaper hedge for them.
          3. During the peak times, we are exporting power for $0.15 per kWh and they are selling that for $0.40 to $0.50 to others.
      • +1

        I also notice that ambers prices aren't accurate. They will say it costs 3c to import, but ends up being 10c.

        • Network tariffs need to be added

        • -1

          100%. You need a degree to read their bills. And the prices don't align to what you see in the app.

      • +1

        Eh, im still over $200 in credit on Amber from summer and im very conservative using battery booster setting. Like mobile networks its all variable.

    • +5

      Depends which state you're in.

      The economics for Amber are much worse in VIC as you don't usually see the wild swings.

      The biggest (non-moveable) use of electricity is usually heating and cooling. In VIC, it doesn't really get consistently hot enough in summer for A/C to put much of a strain on the grid, and in winter, most of the state is still on gas heating. It's not like in QLD where wholesale electricity prices can go crazy in summer.

      • Ah okay, interesting. I might switch over to GloBird then. Would you recommend the new plan or the old one?

        • +1

          I think it depends on your personal circumstances.

          I'm also not sure if you're still able to sign up for the old plan.

          If you have an oversized battery and lots of solar, then the new plan would work well for you - it'll be easy to just charge your battery with your own solar and top up during the 3 free hours of grid charging to get your battery full.

          You can then easily avoid usage between 6 - 9pm, which gets your the $1, and you should have plenty to export back to the grid to take advantage of the 15c/kWh FiT. It's limited at $2.25 per day, so the most you can sell back is 15kWh.

          If you have a 45kWh battery, for instance, that means you can sell 15kWh, and keep 30kWh for your own usage throughout the night and into the morning before you harvest solar again.

      • I’m in QLD and Amber is terrible. Was with them for a month and a half, with a 42kWh battery, and was having a bill of like $90 a month. Feed in prices rarely topped 20c, and buying electricity even during the middle of a sunny day was regularly 10c/kWh.

        Smartshift is hot garbage. It often left me with nowhere near enough battery to last until solar kicked in the next day, having to buy a few bucks of power overnight.

        Switched to globird after that and after getting the automation set up - the “no grid use between 6-8 to get $1” is harder than you’d think. Just doing normal stuff while being “100%” battery powered used more grid power than they allowed, forfeiting the $1. Even force discharging 3kW per hour to the grid still used more than 0.03kWh in an hour. I have to put mine up to 5kW/h export to avoid drawing from the grid to get the $1.

        More I comfortably make $0.50-$0.75 profit per day without lifting a finger. Doesn’t sound like much, but our power bill used to be $9 per day, so it’s a massive money saver that will pay itself off in a couple of years!
        …..
        …..

        Unless of course they change the plans like this, which would mean I’d have to feed almost half my battery back to the grid just to cover the daily fee. Is this plan change for existing customers or only new ones?

          I think your experience is broadly correct - basically Amber is not the right solution for people who want a "no frills, set and forget" solution.

          Yes, Smartshift is marketed as that, but as you correctly point out, it's not perfect and has its issues. All of the people I know who are making money on Amber basically have scripts and automation routines set up that monitor prices, and have algorithms to charge or deploy based on things like weather forecasts…etc.

    • I am with Amber - pretty disapointed. My first bill was $60 for the month with a 42kw battery purely due to not having the ability to export for anything over 11c/kilowatt.

      Not worth it in a good area with good infrastructure.

      • +2

        Amber is rubbish. Globird is by far best option with large batteries. I went from amber to glow to
        Globird.

    • I tried Amber for 2.5 months and moved out, The smartShift let them control your battery with VPP. In summer when it is 40c was getting good FIT (one day I made $60, but when temp is mild it is not worth it, plus during day TIF is -ve. Give it a try for month and see if it worth it for you. PS: I had 42kw Fox battery and 15kw inverter 3 phase, and 17kw solar.

      • -1

        In QLD in summer at 40 degrees c I still never saw any feed in over about 25c max. The app would be like “feed in will be $7/kWh tonight! Let’s fill the battery at 25c/kWh!!!” only for the “expected price” of $7 to drop to 20c an hour before that time.

        Complete joke, and borderline false advertising if you ask me.

      • I had 42kw Fox battery and 15kw inverter 3 phase, and 17kw solar

        All good if you don't want to share, but how much did you pay for this system after rebates?

        I was an early adopter of the Powerwall 3, so I definitely overpaid, but my old man's been thinking of putting in a Fox system.

        • You paid the going rate at the time. It wouldn't have been overpaid. You could really say that about anything technical. Batteries will continue to decrease in price per kWh so in 5 years time people wil say they overpaid today.

          • @mysterytal:

            You paid the going rate at the time. It wouldn't have been overpaid. You could really say that about anything technical. Batteries will continue to decrease in price per kWh so in 5 years time people wil say they overpaid today.

            Yeah, I know what you mean.

            But I do think we've just seen a drastic reduction in price over the past 6 months or so where the price per kWh has fallen drastically. It wasn't that long ago where a dual Powerwall 3 setup would have been around $20k for 26kWh of storage, so around $760 per kWh, and even a bottom of the basement AlphaESS system would have been around ~$500 per kWh.

            These days, it's $7k for a 42kWh FoxESS system, so $160 per kWh. I doubt that you would see like a 70-80% price reduction within 6 months at any point in the future. If anything, with rebates drying up, large systems would likely be more expensive for the foreseeable future .

        • I installed solar while building ~ 1.5yr ago paid $6k with Sungrow inverter, then installed Fox battery / Fox inverter 6month ago paid $7k

  • Is it an auto upgrade to the new plan or do I have to change something on my end?

    • From what I understand you need to opt in. Existing customers won't be put onto this since we all signed contracts for the previous rates and conditions.

  • Personally, I might be an outlier, but I prefer the four4free plan and use that to charge the battery.

    How big is your inverter and battery? If you can't fill it in the Zerohero plan then it would make sense that you prefer the 4forfree.

    • 51kwh battery. 15kw inverter. Usually charged within two hours. However, we have a big central AC which can take 6kw at a time. So just playing it safe.

      Our daily power bills were $10-$20 a day even with solar

      • Yes similar situation here with high AC consumption and big battery and decided to go with 4hourfree plan. I am averaging 50c to 70c net credit a day after accounting for daily usage charges since moving to this plan

      Because…?

      I'm on the Flow Power site now. From their pdf you get 45c/kWh for 5:30pm-7:30pm (I assume this is uncapped?) and $1.21 daily supply for me on Endeavour on a ToU plan. 0c/kWh on exports outside that window.

      The big upside for Globird is that I can roll credit onto my gas bill because Globird offers that too.

      For Flow Power can you cash out your credit easily?

      • Apparently cash out has become easier. You request it via email.

        I think I'll be moving from Amber to FlowPower soon.

        flow power is good if you have big panels to charge your battery. I have tiny panels so will have to use free grid electricity to charge my battery.

        Making $150+ a month with a 42kwh 3phase 10kw inverter. That's why.

        • What electrical provider/plan are you on ? I have the same setup but in a single phase unit

        • what are your projections for Winter?

          Same here. Making anywhere from 150 to 200 a month with 42kwh single phase 10kw inverter 13.2kw panels. My bill before getting batteries was about 130 to 150 bucks.
          Globird is ok if you have high self consumption with battery only big enough to cover peak usage but otherwise, I don't get why people rave about it.

      Way better until winter.. just changed from Flow Power because I’m no longer 100% sufficient from solar. The less I produce the more OVO/Globird makes sense

      • Correct, i think flowpower works best summer and if you have mega solar panel, for winter use plan with free3 hrs

    • Couldn't agree more. It's the best option in VIC at the moment if you have big battery and big solar. On cloudy, non optimal days, I charge off the grid when price is low and cover the cost during happy hour. Most other days I'll export as much as I can during happy hours. Daily profit of around $5-$8.

      • Sorry who are you with and what plan?

  • +8

    The most you can make from globird even with this update is $96-$98 a month (minus supply charges). It's easy to get well over $200 every month from flow power if you're able to export around 20kWh during the export window.

    Although I am curious how they'll structure the government's solar sharer mandated 3-free hours from 1st July, no way that'll be sustainable with the 45c exports every day.

    • If we get Flow Power 45 cents with free 3 hours I'm gonna need to buy more batteries, fantastic deal

      If you've been researching wholesale companies like Amber, you'll notice that during the free charge window, the wholesale feed-in rate can even turn negative. That's because the grid does not actually want excess energy being exported at that time.
      For users like us with batteries, we're effectively helping the grid by absorbing surplus electricity—since not all solar households have battery storage to do so. In that sense, we are part of the solution rather than the problem.
      This oversupply during the free charge window is a structural issue. It may ease somewhat in winter, but it becomes much more pronounced in summer when solar generation peaks.
      Based on this, I believe the 3-hour free charging window is unlikely to be removed anytime soon. However, the 45c export rate is clearly not sustainable in the long run.

      It won't be offered on every plan, they just have to offer 1 plan which has the 3 free hours. For that plan you won't be gettign 45c export.

    • Can you still make that amount of money if you charge 30kwh from the grid during the day ?

      • Not sure what you mean, the power available to you during 11-2 is free.
