Huge Tesla Energy Storage Plus Wind Farm Equals Stabilized Power For Australia – Video

2 months ago by Mark Kane 15

The world’s largest battery energy storage system (100 MW / 129 MWh) is to be installed later this year in Australia, using Tesla Powerpacks (which are utilizing Samsung cells).

Tesla Powerpack to Enable Large Scale Sustainable Energy to South Australia

Naturally, such a big system needs to have an appropriate task for operation, and in this case, it will be support for the Hornsdale Wind Farm, which is operated by renewable energy provider Neoen near Jamestown.

The Hornsdale Wind Farm consists 99 3 MW turbines out of 105 planned (315 MW).

As the wind accounts for one-third of the total power mix within the South Australia state (2014-2015 data), there is a need to secure the grid with some reserves.

The Tesla ESS is expected to help solve power shortages, reduce intermittencies, and manage summertime peak load to improve the reliability of South Australia’s electrical infrastructure.

Here is interesting description of 2016 blackout that maybe could have be prevented with more energy storage:

“The AEMO report says three transmission lines were damaged during a September 28, 2016, storm. The storm produced tornadoes with wind speeds up to 260 kilometers (km) per hour. Two of the tornadoes almost simultaneously damaged a single circuit 275-kV transmission line and a double circuit 275-kV transmission line, roughly 170 km apart. The damage to those transmissions lines caused them to trip, which set off a serious of faults that resulted in six voltage dips on the grid in just two minutes.

“As the number of faults on the transmission network grew, nine wind farms in the mid-north of SA exhibited a sustained reduction in power as a protection feature activated,” the AEMO report explains. “For eight of these wind farms, the protection settings of their wind turbines allowed them to withstand a pre-set number of voltage dips within a two-minute period. Activation of this protection feature resulted in a significant sustained power reduction for these wind farms. A sustained generation reduction of 456 megawatts (MW) occurred over a period of less than seven seconds.”

As the wind farms failed, demand was increased for imported power flowing through the Heywood Interconnector, which allows for power flows between SA and Victoria. “Approximately 700 milliseconds (ms) after the reduction of output from the last of the wind farms, the flow on the Victoria–SA Heywood Interconnector reached such a level that it activated a special protection scheme that tripped the interconnector offline,” the report says.”

    I’m surprised that Australia hasn’t just put in a bunch of combined cycle Natural Gas plants. That’s got to be wayyy cheaper than the wind turbines and batteries. and although not carbon free the combined cycle plants do have a fairly low GHG signature since they are almost 60% efficient.

    1. Mikael says:

      “fairly low GHG signature”? I hope you are kidding…

      “not as extremely high as the worst possible other solution” would have been a better way to put it.

        Meh.

        “Most of Australia’s energy is generated centrally and relies heavily on traditional energy sources, known sometimes as fossil fuels. In fact, around 86 percent of our electricity is generated from these fuels types, with 73 percent from coal and 13 percent from natural gas.Jan 22, 2015”

        https://www.originenergy.com.au/blog/about-energy/energy-in-australia.html

        “CO2 emissions from power plants using combined cycle technology are about 50 percent lower than most coal-fired plants. Emissions of NOx and SO2 are 80 to 90 percent lower. … The energy conversion rates for combined cycle gas turbine (CCGT) plants are high, ranging from 50 to 60 percent.”

          That’s assuming your natural gas network doesn’t leak methane anywhere, or God help us, rely on LNG imported on tankers that burn bunker oil.

          1. georgeS says:

            yeh super I know that.

            Combined cycle has a pretty decent cost per lb of GHG reduction.

            You won’t be able to afford to do it all with windmills and Tesla batteries.

            The point is if you can do a mix of combined cycle natural gas AND wind with battery backup you have just cut out huge quantities.

    2. Just_Chris says:

      South Australia has a number of combined cycle gas turbines and is also constructing an additional unit for the days when it isn’t windy. The AEMO just release a report that shows SA paid $60 million AUD for frequency regulation and that it needs about 35 MW for that task. If this battery can provide half that service it will pay for its self in a year. The other thing that this battery may allow is the relaxing of the regulations around the number of gas turbines the state has to run if there is more than 1200 MW of wind energy entering the system (currently 4). This is to protect the state from black out if there is a loss of the interconnectors to the rest of the country. If the battery can become one of the 4 dispatchable generators, the solar thermal plant they are building can become another and the ZEN energy big battery becomes number 3 then SA is one step away from only needing gas for backup and, more importantly, it can become a net electricity exporter to other states displacing other fossil generation. We are a long way from SA getting to the point where it no longer needs gas generation but 50%+ renewable generation is looking pretty likely, which is impressive for a state with no hydro.

      Great idea! While we’re at it, perhaps we could use this technology to burn 40% less whale oil and consume 27% less baby seal fur!

      Or maybe they’re not dicking around with “using less” of something that’s wholly repugnant and doing their damnedest to eliminate it instead.

  2. Don Zenga says:

    There you go Tesla.

    World’s modern wind turbine started with 22 KW machine in Denmark in early 1970’s.
    Now an average turbine has 2 MW (2 000 KW) in size and nice to read about these turbines having 3 MW which will further increase the average turbine size and lower the cost.

    Ideally Natgas should be used in heating / transport instead of power gen which can be left to Hydro, Nuclear, Solar, Wind, Wave, etc.

    1. Mikael says:

      Ideally natural gas would not be used at all. Fossil fuels have no future.

  3. Alex says:

    It is not wayyy cheaper if you have gas in the north as Australia has and need it in the south as Australia does. You need to build thousands of miles of pipelines or liquefying facilities. Either option costs billions.

    Also it is not that Australia doesn’t have enough electricity. Most of the the time it has more than enough, which means all that gas infrastructure including generating facilities would only be required a few minutes a year.

    Meanwhile wind as a resource is free and overall wayyyyyy cheaper. The blackout didn’t happen because there was not much energy, but because there was no backup for a few seconds.

    That’s typical problem with wind. And storage comes up as an ideal solution.

    Now also wind along with storage can be set up in a matter of weeks, not years. 100 days or free as Musk put it.

  4. Alex says:

    Nobody is stupid to buy technology A, if there is a cheaper / better alternative B. In this case however to the dismay of country coal and gas lobby there was no alternative. Australia is probably the biggest exporter of coal and one of the biggest for LNG. There would have been no place for outsiders had local incumbents been up to it.

  5. Pushmi-Pullyu says:

    This article points up the very real economic advantage of having just a couple of minutes’ backup for grid energy. Of course we all hope to see the day when the utilities can balance supply and demand over a 24 hour period — or even longer — but even a couple of minutes’ worth of emergency backup can go a long way toward stabilizing the grid, eliminating costly spikes or sudden dropouts, and prevent cascade failures which can result in widespread blackouts.

    Batteries will have to come down in price quite a bit before we can expect utilities to be able to buy enough to balance the grid over a 24 hour period. But in the meantime, before than can reasonably happen, there is a market for short-term grid backup. The cost/benefit ratio works much better for short-term grid power storage than for longer-term storage.

  6. Doggydogworld says:

    This installation is NOT the world’s largest. That would be the AES 160 MWh project with SDG&E beats it. This project has the highest power rating.

    This is a Neoen project using Samsung batteries. I’m not sure what Tesla’s involvement is, beyond providing publicity.

    The blackout happened because the wind farms were programmed to shut them down after 3 or 4 voltage dips in a short time window. It was an arbitrary setting which no one really knew about and has since been changed. The same scenario today would not cause a blackout.

    That said, storage batteries can be a cheap way to handle sudden disruptions. Not nearly as cheap as a bunch of EVs on smart chargers, though.

  7. Philip Reeve says:

    “I’m not sure what Tesla’s involvement is, beyond providing publicity.”

    That’s one way of looking at Tesla’s involvement, Doggydogworld. Over the past decade, that “publicity” has been the catalyst for a total change in mindset of the world’s biggest auto manufacturers.

    Tesla have also done what no other manufacturer (or government) has done – provided a comprehensive, fast charging EV network on all major continents.

    I have a sneaking suspicion that that Tesla’s achievements are the result of more than a little “publicity”.

  8. Martin T. says:

    Yes the Tesla batteries are urgently needed for Base load as the current South Australian government screwed up.
    The base load issue is the elephant in the room.
    One could understand if the SA government could harness ocean waves for when the sun and the wind don’t operate. But they are not exactly bright about base load. Lucky Tesla has a solution for these clowns. 🙂
