Tesla’s Lithium-ion Battery Responding to Power Outage in Record Time


The World’s largest Lithium-ion battery based backup power system put up by Tesla in South Australia is proving its mettle. It’s perform ace is far beyond expectations. In the last three weeks the Hornsdale Power Reserve has responded quickly to two major energy outage. The response was even quicker than coal-fired backups that were supposed to provide emergency power.

The Tesla battery supported the Loy Yang facility in the neighboring state of Victoria when it suffered a sudden drop in output. The response time was record 0.14 seconds. In the week before another failure at the same facility prompted a response from the Hornsdale battery in less than 4 second0073.

The performance and effectiveness of Tesla’s battery is being closely watched in the region as it is often impacted by an energy crisis. The state of South Australia has seen soaring prices of electricity. In 2016 a major power outage impacted more than 1.7 million users and caused a blackout. The region often falls prey to storms and heat waves that lead to additional outage.

Tesla’s battery system uses the same energy storage technology that is used in Tesla’s electric cars. The wind turbines feed the battery with the energy that it stores when the electricity demand isn’t peaking. The battery can support up to 30,000 homes for a short period. Albeit, it is for short period and hence the battery still needs to supported by traditional power plants in the case of long power outage.

Elon Musk, the Chief Executive of Tesla vowed on Twitter to deliver the battery system for South Australia’s struggling power grid in less than 100 days or it would be free. The state signed a deal with Tesla and the France-based energy company, Neoen to produce the battery. By Dec, 01st, South Australia announced that it had switched to Hornsdale battery.
