Tesla's Massive Australian Battery Responds to Coal Power Outages in Milliseconds
The system—the largest of its kind on planet Earth—was tested twice just this month. According to CleanTechnica, on Dec. 14, the Loy Yang coal power plant in the neighboring state of Victoria suddenly went offline. Remarkably, the Hornsdale Power Reserve battery system (the Tesla system's official name) kicked in within 140 milliseconds and injected 100 megawatts of power into the grid.
Two weeks later, another unit of the Loy Yang plant unexpectedly went offline. Tesla battery's also responded within milliseconds to send 16 megawatts to the grid.
“That's a record and the national operators were shocked at how quickly and efficiently the battery was able to deliver this type of energy into the market," State energy minister Tom Koutsantonis commented after the Dec. 14 outage. “Until now, if we got a call to turn on our emergency generators it would take us 10 to 15 minutes to get them fired up and operating which is a record time compared to other generators."
The 100-megawatt Powerpack system, which charges using renewable energy from Neoen's Hornsdale wind farm near Jamestown, is designed to hold enough power for 8,000 homes for 24 hours, or more than 30,000 houses for an hour during a blackout.
Tesla CEO Elon Musk famously made, and won, a bet that his company could build the battery within "100 days from contract signature or it is free." The giant battery officially switched on in early December.

The EPA announced last week that it is issuing a preliminary regulatory determination for public comment to set an enforceable drinking water standard to two of the most common and well-studied PFAS, PFOA and PFOS.
This decision is based on three criteria:
- PFOA and PFOS have an adverse effect on public health
- PFOA and PFOS occur in drinking water often enough and at levels of public health concern;
- regulation of PFOA and PFOS is a meaningful opportunity for reducing the health risk to those served by public water systems.

Driving an electric-powered vehicle (EV) rather than one reliant on fossil fuels is a key way to tackle climate change and improve air quality — but it does leave the old batteries behind as a nasty residue.
Finance ministers from the 20 largest economies agreed to add a scant mention of the climate crisis in its final communiqué in Riyadh, Saudi Arabia on Sunday, but they stopped short of calling it a major economic risk, as Reuters reported. It was the first time the G20 has mentioned the climate crisis in its final communiqué since Donald Trump became president in 2017.
