Recently, Tesla protected a grid from coal plant failure in South Australia within less than a second right before the coal plant was about to go offline. The Tesla battery responded, stabilized the grid and went back offline even before the generator contracted to do the same.
The 100 MW or 129 MWh lithium-ion mega battery by Tesla started operating officially in December 2016 in order to curb blackouts. Though the region has wind farms supplying over 40% of electricity, a backup was required at times when there’s no wind and the demand exceeds supply. The Tesla battery collects power that can be used at non-peak times to ensure no blackouts in future.
The coal-powered backup was about to start but the speed at which the Tesla battery kicked in proves that such technology can replace backups in power grids around the world.
