Tesla says its Osaka station Powerpack is Asia’s largest energy storage system

Tesla has built another Powerpack system in record time, this time at Osaka train station in Japan, where it will be used as emergency backup and to reduce peak energy demand. According to the company on Twitter, the 42 Powerpack units will provide enough energy to safely move a train and its passengers for up to 30 minutes to the nearest station in the event of a power failure.

Tesla says the 7MWh project makes it the biggest energy storage development in Asia, and like its giant Australian Powerpack system, it was completed with eye-watering speed — the hardware was apparently installed in just two days.

Osaka’s trains are some of the busiest in Japan, transporting millions of people every day, so Tesla’s Powerpack will undoubtedly prove a blessing during power interruptions. While the company’s energy division tends to take a backseat to its EV work, its 2018 figures show it’s playing an increasingly prominent role not only within the Tesla empire, but across the energy storage landscape in general. Last year the company deployed 1.04Gwh of energy storage, nearly triple the 358MWh rolled out in 2017.
