Tesla Powerwall 2 battery storage opens for orders in Australia

One Step Off The Grid

Less than a month after Tesla unveiled its Powerwall 2 home battery storage system at twice the capacity and around half the price (per kWh) of the first Powerwall, the new improved unit has opened for orders on the Australian market.

Tesla said on Wednesday that its 14kWh Powerwall 2 batteries were available for order online and in Tesla stores in Australia, as well as through the US company’s accredited local resellers, with installations here set to begin in February 2017.

According to the Tesla website, the lithium-ion batteries will cost $A8,000 per unit, with installation and “supporting hardware” starting at $1,450. According to an online quote from one accredited Australian Tesla reseller, a 3kW solar system with a Powerwall 2 would start at $17,900.

Interestingly, the original 7kWh Tesla Powerwall is still being advertised on this same website, but questions about the cost of the first generation battery – given the price of the Powerwall 2 – were not immediately answered.

As we reported at the time, and noted above, Tesla’s Powerwall 2 made quite a splash when it was launched in October in LA, alongside the company’s solar roof, next generation EV charger and commercial battery storage unit, the Powerpack 2.

As CME analyst Bruce Mountain wrote at the time, not only did Tesla effectively halve its battery price per kWh in less than a year, but it signalled that PV+battery+grid was “level-pegging with the average grid-only market offer …and cheaper than the average grid-only Market Offer (before conditional discounts).”

And Tesla’s Elon Musk is confident it will do even better than its predecessor. In a Q&A following the launch, Musk said his company “expects to sell more Powerwalls than cars,” owing to potential demand for the product in parts of the world where power isn’t reliable or even accessible – or is very expensive, as in Australia.

Tesla’s focus in Australia, however, appears to be on the hundreds of thousands of households in NSW, South Australia and Victoria that have long since had rooftop solar, but who are about to lose their premium feed-in tariff.

“With over 275,000 Australian households affected by the reduction of feed-in tariffs  …the timing for Powerwall 2 to launch into the Australian market is ideal,” the Tesla release said on Wednesday.

“Most homes use only a fraction of the solar energy they generate, with owners currently using the benefits of the feed-in tariffs to gain the value from their asset. Powerwall 2 allows home owners to use more of their solar, storing the energy to use at any time rather than sending the excess energy back into the grid for the low return that is about to begin.”

Below are the specs as set out by Tesla reseller Natural Solar.

    Plan A & B are in taters soi what’s going to be Plan C

    • Rod

      I think plan C has started.
      The (Dirty) Energy Council was on ABC the other day warning of dire consequences if much more PV is installed in SA. System security blah, blah, blah.
      I don’t think we have anything to worry about. Storage will take those extra MW/h and shave those peaks.

      • Cooma Doug

        About a decade ago I remember talking to a group of energy industry people. After a few questions and talks it appeared that we spend 40 to 50 % of our energy costs on preventing 5 min of black out a year.
        Conclusion at the time was we have to prevent escalation into system black and we cant store electricity. We dont have the technology to manage loads.

        Obviously we need to have a bit more of a look now. If we do it right we will reduce the cost somewhete near that 40%. If cars replace poles and wires in the cities we will also still have a grid. Worth talking to via your car computer/ power manager.

        • Rod

          Yes, much of the “Gold Plating” of the grid was about newly privatised utilities meeting Service Level Agreement levels of outages.
          So, dual and sometimes triple redundancy was built to minimise outage time.
          Local mini-grids will make these assets redundant.

        • Brunel

          I wonder if diesel generators could have supplied the electrons during the 5 minutes for a lower price than gold plating.

          There would have been diesel generators at radio stations and hospitals anyway.

  • Mike Dill

    $A700/kWh installed. Well, that is going to roll the market. By 2018 the price should be where I want to buy.

  • trackdaze

    Possible to cut the utility cord. Add an ev that you can charge elsewhere and you effectively have grid independance.

    • Cooma Doug

      Cars pulling down poles and wires. Ive been suggesting this for about 5 years. Hope it is possible as it will enable high density residents to be power indeoendant. This is a must do moving past 2030

  • Andrew Roydhouse

    Redoing the maths to compare TOTALLY cutting yourself off from the grid makes it now a question of personal greed/reticence rather than the pre-Powerwall 2 launch – the greater cost. Especially for someone in a typical city suburb – the only (ethical) issue is the over-generation of power. If on good terms with your neighbours then a heavy duty extension cord over/through the fence for their aircon or pool pump may be a solution.

    The quote shown above for a battery and 3kw installed seems VERY expensive for the 3kw of panels. A quick examination of the monthly updates from this very site shows that you can get 5kw of grade 1 panels installed for a couple of thousand less than the quote for the 3kw added to a Powerwall 2.

    Perhaps the installer is charging a premium for access to the Tesla product?

    If so, is this something that Tesla approves of? Knows about?

    Or am I missing something?

    • Brunel

      I feel the same way about the NBN.

      2 houses can share a fibre optic connection.

      It is dogma to think that every house must have a direct fibre link.

    • The solution to the waste of excess electricity generation is to remain on-grid and sell back your excess electricity to the grid @ the wholesale market rate using Reposit Power: http://www.repositpower.com

  • Alen T

    Spec details appear to questionable. 100% DoD for Li-ion is unlikely, unless the quoted capacity is in fact the usable value, i.e. capacity post DoD calculation.

  • Ronald Brakels

    A three kilowatt solar system, on average, won’t even produce enough electricity to fully charge a Powerwall 2, let alone meet household demand as well during the day.

    • Yes, a 5Kw system would be the minimum. There is a limit on one phase connections @ 5kW. 🙂

      • Ronald Brakels

        Here in South Australia we can install a 10 kilowatt solar system on homes with single phase power but a lot of people are going to have problems. For example in the Endeavor network area in NSW people with single phase power are limited to both inverter and a total panel capacity of under 5 kilowatts.

        • I have been told that special dispensation can be requested for a larger system for one phase power in NSW. I haven’t tested that as yet. 🙂

          • Ronald Brakels

            I wonder what Endeavor and Ausgrid’s attitudes towards people installing export limiting equipment is? That may be one way people could install enough PV to charge up their Powerwalls.

  • Fantastic news! Combined with Reposit Powers ‘sell back excess stored electricity to the grid at market prices’ piece of hardware we’ll no longer be at the mercy of polluting and visionless fossil fuel power! 🙂
