    How did they make the deadline?

    Tesla skipped the testing. No load or grid testing was done.

    Tesla had a massive unboxing party, plugged the boxes of loose parts together, plugged in wires to the grid (hopefully), and declared success...according to the fine print in the "bet" paperwork.

    Tesla: World’s biggest battery almost ready in Australia

    "Audrey Zibelman, chief executive of Australian Energy Market Operator, which manages the Australian electricity grid, said on Tuesday she expected the battery would be ready by Friday, the first day of the Australian summer when power use on air conditioning soars.

    “We’re in the process of testing that battery right now and we expect it to be ready on Dec. 1,” Zibelman told Australian Broadcasting Corp.

    “That’s the end of this week and so we’ve done an incredible amount of work and I have to say I’m very pleased and delighted with Elon’s staff. They’ve worked incredibly hard have done numerous things to get ready for the summer,” she added.

    State Premier Jay Weatherill announced last week that Tesla had finished installing the battery power packs near Jamestown, about 120 miles north of the state capital Adelaide."

    Only one problem remains, the battery site wasn't built near enough to a Tesla SuperCharger Station, and the charging cable won't quite reach, they are waiting for the cable extension to be delivered... whaaaattt??!! :D:confused::p:eek::rolleyes:o_O

    How many Tesla 3's could have been made with the batteries used to build the Australian Battery farm?

    Actually, now that I think about it, timing is about right, and size of the construction looks it as well too.

    We know that the car batteries are meant to eventually be reused in Tesla "wall batteries" to eek more life out of the waste of resources that each battery represents, so they are interchangeable.

    Tesla Model 3 production was slow because a supplier 'really dropped the ball' said Elon Musk
    Model 3 was delayed because Tesla had to redesign a key piece of supplier software.
    Tesla will be able to claw back some money from supplier, but not enough to make up for lost revenue.
    https://www.cnbc.com/2017/11/01/tesla-model-3-production-problems.html

    "Tesla CEO Elon Musk said production of the electric car maker's Model 3 sedan was held back in large part by a supplier who "really dropped the ball" at the Gigafactory."

    The Gigafactory is where Tesla constructs the batteries for all the Tesla products.

    "The primary production constraint by far is in battery module assembly," said Musk, who said he has been working out of the Gigafactory in order to be closest to the largest problems in Tesla's production line.

    There are four "zones" in battery module production for the Model 3, and there was a particularly severe problem in one of them, Musk said.

    "This is where a systems integration subcontractor really dropped the ball, and we did not realize the ball was dropped until recently, and we had to rewrite the software from scratch," Musk said."

    Tesla has produced batteries in that factory for over a year, and all the vetting of production rates should have already been known within a small margin.

    How could Tesla mismanage the battery production to the point where it gave away all the promised Tesla 3 production batteries and had them put into the giant Australian battery project?

    And, then try to blame the battery "shortfall" on a "software" vendor?

    Really?

    "Tesla's ability to ramp up production of the Model 3, is of particular concern to investors. Tesla produced only 222 Model 3 cars during the quarter, the company said in a letter to shareholders. The company had expected to produce about 1,500 during the period."

    IDK what the capacity is of the Tesla 3 batteries vs. the batteries used to construct the Austrailia (and Puerto Rico) battery farms, but I wouldn't be surprised to hear the 2 of them add up to about 1278 Tesla 3's worth of battery capacity.

    You would have though it would have been inside a building were you can regulate the temperature of the battery`s easier to protect from storms dust/dirt ect, you could have put solar panels on the roof.

    Tesla big battery outsmarts lumbering coal units after Loy Yang trips
    By Giles Parkinson on 19 December 2017
    http://reneweconomy.com.au/tesla-bi...bering-coal-units-after-loy-yang-trips-70003/

    "The Tesla big battery is having a big impact on Australia’s electricity market, far beyond the South Australia grid where it was expected to time shift a small amount of wind energy and provide network services and emergency back-up in case of a major problem.

    Last Thursday, one of the biggest coal units in Australia, Loy Yang A 3, tripped without warning at 1.59am, with the sudden loss of 560MW and causing a slump in frequency on the network.

    What happened next has stunned electricity industry insiders and given food for thought over the near to medium term future of the grid, such was the rapid response of the Tesla big battery to an event that happened nearly 1,000km away.

    Even before the Loy Yang A unit had finished tripping, the 100MW/129MWh had responded, injecting 7.3MW into the network to help arrest a slump in frequency that had fallen below 49.80Hertz.

    Data from AEMO (and gathered above by Dylan McConnell from the Climate and Energy College) shows that the Tesla big battery responded four seconds ahead of the generator contracted at that time to provide FCAS (frequency control and ancillary services), the Gladstone coal generator in Queensland.

    But in reality, the response from the Tesla big battery was even quicker than that – in milliseconds – but too fast for the AEMO data to record.

    Importantly, by the time that the contracted Gladstone coal unit had gotten out of bed and put its socks on so it can inject more into the grid – it is paid to respond in six seconds – the fall in frequency had already been arrested and was being reversed.

    Gladstone injected more than Tesla did back into the grid, and took the frequency back up to its normal levels of 50Hz, but by then Tesla had already put its gun back in its holster and had wandered into the bar for a glass of milk.

    So why did the Tesla big battery respond when not contracted?

    One reason is because it can, and so it did.

    The other reason is less clear, but more intriguing. It is contracted to provide such grid services by the South Australia government.

    The details of that contract are not released, but it wouldn’t surprise if that contract allowed, or even encouraged, such intervention – just to rub in the message about a cleaner, faster, smarter grid to the technology dinosaurs in the eastern states.

    Marvellous stuff.

    This is just the latest in a series of interventions since the Tesla big battery was officially opened in early December."
