Tesla Battery Saved Electrical Grid In Australia When Coal Failed

By Brian Spaen

Tesla’s new battery backup facility at an Australian wind farm has already passed a hefty test when a power outage occurred this week. Interestingly enough, instead of it coming to the aid of the renewable energy, it helped out a failing coal-fired power plant. How did this happen? In short, the battery left the fossil fuel’s backup service without anything to do as it was pushing energy into the grid.

Elon Musk was able to hold his promise of a 100-megawatt Tesla Powerpack being built in a matter of months at the Hornsdale Wind Farm in South Australia. It became active when it detected that the Loy Yang coal power plant went offline for an undisclosed technical reason. The battery was able to inject over seven megawatts into the national grid in record time -- 0.14 seconds.
