        Actually it's just a cheap way to incentivise private investment to get more energy storage (and renewable energy generation) added to our electricity grid, instead of directly paying for infrastructure. Grid can service more renewables, wholesale prices get pushed down for everyone… Win win win.

              @jhaley3180: very hard to argue with so many dummies here at once
              do yourself a favour
              look up energy price index over years and you will see that from 2007 it started to skyrocket - privatisation occurred much earlier
              what happened in 2007? Rudd government
              On 1 December 2007, the then Government committed to expand the Renewable Energy Target to 45,000 GWh by 2020. The changes aimed to have the equivalent of at least 20 per cent of Australiaā€™s electricity supply generated from renewable sources by 2020
              then we had carbox tax and between 2007 and 2013 energy price more then doubled, that never happened in the history before.
              then every new goverment that came in had their renewable targets and were pushing away from coal
              in the end we can all see the results - look at your bills and see what you are paying, its not hard to figure out - but for some it must be.

            @botchie: Electricity prices rose around 130% under the last 9 years of the Liberal party rule with the stifling of renewables and pushing coal/gas as far as it can go, and with ~20 different energy policies in that time (a different energy policy every 6 months or so). Electricity prices rose around 1.2% under the last 3 years of the Labor party rule where they pushed an explosion of renewable deployment with consistent policy to do so, drastically lower than inflation in this period.

            Seems like renewables are cheaper to me?

              Electricity prices rose around 1.2% under the last 3 years of the Labor party

              Can you prove it?

              FWIW, my electricity price went up 10% in last year year alone.

              Also, temporary Govt energy bill relief doesn't mean cheaper electricity prices. Like if govt pays full household electricity bill, it wouldn't mean electricity prices have gone down to ZERO for everyone, including businesses.

                @dealhunter52: https://aemo.com.au/energy-systems/electricity/national-elecā€¦

                Go here, click on the "Annual" tab. It's a volatile set of numbers, but you can see it trending generally steadily up quite heavily under the nine years of Liberal rule from 2013 to 2022. Between 2022 and 2025 there has been a modest decrease actually when averaging across states, so my previous claim of "increase" under Labor was incorrect.

                Your electricity bill rising will be fairly loosely tied to these increases/decreases in prices over the years. 10% in one year seems accurate, by the above calculation of 130% over 9 years, that's about 14%/year increase. If your prices haven't been updated for a while your retailer might have needed to push you onto a more expensive plan now to avoid making a loss.

                Hopefully things will start turning around - I'd encourage you to compare energy plans with whatever tools are available to you. I use the Victorian energy compare website at least annually to change/review plans and make sure I'm getting the best offer on the market.

                  You're absolutely wrong on electricity prices rising more under Liberals compared to Labour. According to AEMO electricity prices in NSW in 2013-14 were $52.26 and they were $64.81 in 2020-21 in last full year of Liberal rule. Not only that, they were trending downward from their peak in 2018-19.

                    just shows how you brain dead renewable are cheaper ppl have no clue - its all right in front of you - you just cant add 2 + 2

                    The data shows that electricity prices were relatively flat through the 1990s, but escalated in all capital cities from 2007.

                    Are you seriously trying to argue that the jump from $64.81 to $132.35 was 100% due to Labor in those 40 days in power at the very end of that one FY, and not the nine years of Liberal rule leading up to it? Did your power bill literally go up by over 100% in May 2022? You're dreaming mate.

                      If you think Ukraine war in early 2022 had to effect on global energy prices, I have a bridge to nowhere to sell to you. Global energy prices peaked in August 2022 and were trending downward and by December 2022, they were already at pre-Ukraine war levels. You can show your bias, but can't deny facts.

              @ChaseTheSun: no, you cant believe the spin, look up history and you will see that in 2007 prices exploded , there is only one reason for it and that is that more renewables were being pushed into the grid, use some common sense
              tally up how much government invested into renewable programs and you will easily see they could have build numerous coal generations with it.

            @sareth: I'm sure we could do it with renewables and batteries for far less than the cost of nuclear, plus we'd get it before 2040 as well.

            @sareth: That's why we need to install more storage and renewables. You know we can install enough batteries to supply 6GW (the Liberal's proposed nuclear capacity) overnight for approx. $36B in 2024 prices, and that price is almost half what it was just six months earlier. In contrast, the nuclear plants would cost $115B by the wildly optimistic estimates coming from the Liberal Party.

            Why exactly would we waste an extra $80B on outdated tech that's not getting any cheaper, is more dangerous to run, is a greater domestic defence threat (don't the Liberals care a lot about defence?), reduces the financial viability of other renewable generation because it can't be turned off (baseload is a liability, not a security), and can't supply extra power reactively (batteries can ramp output way up/down extremely quickly, while nuclear output must remain very stable to be safe).

            The Liberal Party complains about various projects being waste, but going with nuclear would literally be pissing $80B into the wind with only negative consequences to show for it.

        • botchie on 05/05/2025 - 10:47

          no, Nuclear is for idiots, we have plenty of coal and gas, we could have a very cheap and robust base load added with renewables which would be way, way cheaper , nett zero is a dumb mans idea

      Hey Impoze,

      It has been confirmed, it was dependant on if they win and they have won. The program is known as the Cheaper Home Batteries Program, scheduled to start paying out from 1st July 2025, batteries can be installed from the announcement date onwards however only be commissioned/turned-on after 1st July (new financial year).

      The rebate will be managed by the SRES scheme, this is the same scheme that already offers Federal STC solar rebates Aus wide for over 10 years. Fairly straight forward process and everyone is eligible as long as the product installed is eligible. To make it even better the rebate is uncapped so gives everyone plenty of time to research and get the right product for their needs.

      The industry and consumers have been waiting a long time for a centralised battery rebate and this rebate makes batteries a lot more financial viable for most users.

          The "up to $8800 loan" is not additional money you have to pay. You would sign up for the scheme for a $4999 loan and this is what you pay for the battery with.

          The loan is interest free over 4yrs so it just splits up the cost instead of it being one lump payment.

          No idea on these ones, but the two Tesla Powerwall 2 batteries that I had installed in 2017 are still going great after 8 years. No idea how long they will last, but they appear to hold charge just fine and have lost maybe 5-10% of their original capacity. I personally would only go for LFP chemistry ones in the future due to their reported even longer battery life.

      Hey Captain Hindsight,

      When a new rebate comes out there is always a feeding frenzy and it can get very hard to compare apples for apples. Wait till you see all these new companies pop up and start offering ridiculous prices, only to shut down after 6 to 12 months (unfortunately happens very often in this industry).

      We always try our best to be fully transparent and offer some of the best deals around, we have been working with the Ozb community since 2020 and only offer quality products that are also affordable.

      The rebates will be a great help for consumers and before the rebates the batteries were frankly way too bloody expensive, still they arn't the cheapest but they make a lot more sense in the current climate. Especially considering the reduction in feed in tariffs about to come in next FY, emergency backstop in Vic and more and more 0 export for many new customers.

      If anyone wants to discuss any specific batteries or their needs please feel free to get in touch. Good thing is that the rebate is uncapped and not going anywhere so absolutely no rush other then long install wait times and manufacturers upping their price to cash in on the rebate. FYI the rebate will reduce every calendar year till 2030, wont be more than a few hundred per year however.

          Hey PegasusBruce,

          That's one of those questions mate it may it may not depending on who the insurer is.

          Batteries are fairly safe nowadays, some actually come with a built in fire extinguisher as well (handy).

          Honestly best to call the insurer and ask.

          Like with most new installations to a property if they are done correctly and to the relevant standards they are safe and insurers would see it the same way. We provide you will documentation and compliance certificates so that you can share these with your insurer as needed.

          From memory we haven't had any customers say that they had to pay more for insurance after install, perhaps Ozbargainers with batteries can chime in based on their personal experience as well.

            @mattcerium: "built in fire extinguisher" - these lithium batteries are not going to be stopped by a small built in fire extinguisher when they go up in flames. They will just have to burn themself out. The only thing that will save the house is if these batteries are wrapped in fireblankets that are now being used to contain EV car fires, or stored in thick metal casing away from the house.

                    Anyway, again, the point is if and when they go up in flames, the small built in fire extinguisher, is going to be useless. If they never go up in flames, then why bother building in a next to useless fire extinguisher for the marketing?

                      I don't know what you are trying to say - are you under the impression that home battery fires are a common occurrence ? It's such an astronomically rare event, that it's just not worth worrying about - there are a gazillion other ways your home can burn down.
