Tesla unveils 18.2MW big battery in Belgium

Tesla has unveiled its latest grid-scale battery – a 140 Powerpack 18.2MW system in Belgium the company says was installed in five weeks.


Tesla has unveiled its latest large-scale battery project, this time in Europe, where an 18.2MW collection of 140 Powerpacks and inverters has been connected to the grid in Terhills, Belgium

The project – which Tesla says took six months to complete from inception to operation, with the battery installation itself taking about five weeks – was unveiled on Tuesday afternoon (Australian time) by the California based company via its various social media channels.

According to ReNews, the €11 million storage array, located at the Terhills resort, is pooled with a mix of demand response assets from industrial and commercial consumers, and is one of the largest batteries in Europe contributing to the grid.

While a fraction of the size of the 100MW Hornsdale Power Reserve “big battery” in South Australia, the Belgian battery bank will be used for similar “grid balancing” purposes on the European grid – as the video below explains.

It will combine with various demand response services to provide around 32MW of grid capacity. The number of Powerwalls – 140 – suggests storage capacity of 28MWh, but this will depend on the final configuration.

If it’s anywhere near as effective as its SA counterpart, it should do a pretty good job.

As RenewEconomy reported on Friday, new data from McKinsey and Co – presented at Australian Energy Week – shows that the Hornsdale Power Reserve has taken a 55 per cent share in the state’s frequency and ancillary services market, and lowered prices in that market by 90 per cent, since being switched on.


Meanwhile, in Australia, work has begun on the Bulgana Renewable Energy Hub in Victoria which will see the state’s first combine wind farm and battery storage, including a 20MW/34MWh Tesla battery.

Tesla is also working on another large-scale battery storage project – the Gannawarra Energy Storage System, which will add a 25MW/50MWh Powerpack battery system to Victoria’s biggest solar farm, the 50MW Ganawarra project in the state’s north-west.

And earlier this month, Tesla CEO and chief visionary Elon Musk let slip about a soon-to-be announced new big battery project that would dwarf the SA installation.

Musk said the new project would be announced within a few months – he did not say where it will be installed – and that at 1GWh it would would be eight times bigger than Hornsdale.

“The utilities have really loved the battery pack. I feel confident that we will be able to announce a deal at the gigawatt hour scale within a matter of months,” Musk told a conference call following the release of the company’s March quarter results.

    While this battery pack may seem small it can make a difference.
    The real news is the Elon Musk let slip about a soon-to-be announced new big battery project that would dwarf the SA installation.

    Now this will be 8 times bigger than the SA instillation and why are they going to do this because best governance in Australia you can believe the figures and international companies look and realise this a proposition I can participate in.

    18.2MW (I presume that because it’s use if FCAS rather than energy storage the MWh rating is less important) isn’t particularly large, so I’d be interested to hear more about its role in the European grid.

    • MacNordic 3 years ago

      Due to the large number of generation assets as well as the rather good interconnection in Europe (EU target: 20% of peak load as interconnector capacity for each country, mostly reached), there is no real need for all that many large FCAS providers.

      An addition of around 2MW of repurposed car batteries in Hamburg by a consortium of BMW, Vattenfall and Bosch mentioned a need for “over 600MW” of that in Germany* – standard peak load 83GW.
      The needed amount of FCAS capacity is derived from the weekly purchase by the grid operators, so pretty reliable.
      Belgium on the other hand is much smaller- around 10-11GW peak load, so the Tesla battery should cover quite a large chunk of the FCAS market…

    It is remarkable that they would not rather say the MWh figure – which is the bigger number!

    23 MWh vs 18 MW.

    Anyone know how they plan to service or decommission these batteries? Does Tesla have the service/decommision contract?

    • Marcus Whitley 3 years ago

      I would assume that there would be a contract for end of life for batteries to either be recycled or reused.

      Tesla generally do a pretty good job at recycling the batteries, pretty sure they can get back 70% or so.

      • Miles Harding 3 years ago

        The company has a plan in place the totally recycle the batteries, it’s not needed yet, as virtually none have failed at this time.

        Re-use of these batteries may be unattractive. JB Straubel (co-founder of Tesla) considers that recycling is more effective than re-use. Teslas are all 300+km vehicles, and a functionally useless battery would have a range of less than 75km (about the same as my 2011 i-Miev with a 70% battery) meaning that a ‘dead’ Tesla batter only has 25% of its original capacity and is likely close to a total failure point.

    Another time that Aussie can do a Paul Hogan….

    “thats not a battery…..THIS is a battery” pulls our HPR….
