How Tesla’s Big Battery saved South Australia from 3 major blackouts


Even the Tesla-powered Hornsdale Power Reserve (HPR) from South Australia has stored businesses and neighborhood residents from three wide-scale blackouts, proving how large batteries may play an integral role in keeping up a place ’s electricity grid.

Even the Hornsdale Power Reserve, owned by French renewable energy producer Neoen, utilizes Tesla’s utility-scale Powerpack system. Based on an impact analysis from consulting firm Aurecon, it seems that the large battery includes saved customers AUD 116 million or roughly $76 million in 2019. The same report detailed the HPR responded to three separate significant events since it went online in 2018. The said events occurred in August 2018, November 2019, and January 2020.

“On each occasion, HPR responded by closely tracking the shifting frequency and accurately altering its electricity dispatch as required,” the Hornsdale Power Reserve Year 2 Technical and Market Impact Case Study read.

Even the Hornsdale Power Reserve provides Fast Frequency Response with its quick capability to guarantee electricity is provided preventing major power outages.

During the August 2018 occasion, the grids from South Australia and Queensland were cut off from the grid after lighting strikes which resulted in blackouts from New South Wales and Victoria. NSW drop 724MW of load although Victoria shed 280MW. Victoria and South Australia did not go from the dark. Tesla’s large battery was fastest to respond during the event and has proven itself as a critical asset where electricity security is required.

“The large-scale battery storage in SA was valuable in this event, helping in containing the initial decline in system frequency, then quickly changing output signal from production to load, to restrict the over-frequency requirement in SA after separation from VIC,” the  Australian Energy Market Operator account regarding the Aug. 2018 occasion reads.

On November 16, 2019, another occasion caused the islanding of this grid in South Australia. In the first day on the date, the Heywood interconnector, the link between South Australia and Victoria, triggered. Despite this, the lights in SA did not go dark, because of wind, solar panels, along with batteries that are large. The Tesla Big Battery responded assisted return the supply in a matter of minutes following the occasion that was islanding and as required. Other energy manufacturers that bill during these events were not able to carry out as well as it preserved the supply in normal variety.

On January 31, 2020, South Australia was once again separated from the National Electric Market due to a storm which broke a enormous transmission line. The trimming transmission lines actually meant there was still an oversupply at SA and just like in undersupply occasions, the Hornsdale Power Reserve, together with South Australia’s other large batteries and windfarms, immediately responded to correct the fluttering frequency. SA effectively functioned like a “island” until electricity had been resynchronized on February 17.

The three occasions in South Australia emphasize the very important role of how Tesla large battery-supplied Hornsdale Power Reserve can help preserve grid security and ensure that lights are retained on even when the country is &ldquo. ” These will be the start also, particularly since Neoen has announced it will be expanding its Tesla Powerpack Farm by 50 percent.
