The company has developed this power storage system in an attempt to reduce the demand for energy and deliver emergency power backup to trains in Japan. The project is launched in partnership with Kintetsu, who is a railway operator at Osaka railway station.

The new power pack system is a completely integrated AC-connected energy packing system which can be connected to a utility network or a building. The system consists of 16 discrete battery pods, in which every battery pod has an isolated DC-DC converter attached to it. Around one to 20 power pack systems can be connected to each Tesla inverter. Moreover, larger systems can effortlessly accommodate multiple inverters that enable flexible system sizing scalable from 200 kilowatt hour (kWh) to 100+ megawatt hour (MWh).

Osaka is one of the busiest train stations in Japan. The newly launched system will certainly prove a blessing during power failures and give a power boost to the trains in Japan. In Addition, the tech major stated that this energy storage system will help to reduce the energy demand at Osaka train station during peak hours.

Tesla stated that the 7 -MWh system is its largest power pack system in Asia, and the fourth largest in the Asia-Pacific (APAC) region. The newly developed system contains 42 power packs which offer ample amount of backup power. In an event of a power failure, the system is capable of securely moving a train and its passengers to a nearby station. In addition, the system can supply 4.2 MW of power at a time. The project was completed with eye-watering speed as it successfully installed the system setup in just two days. Elon Musk, the co-founder and CEO at Tesla stated that certainly the company has a huge opportunity in energy storage system market in the near future.

The company is playing an increasingly prominent role within the Tesla empire, and also across the energy storage sector across the globe. According to analysts, nearly 1.04 Gigawatt hours (GWh) of energy storage systems were installed by the company in 2018. The company aims to provide the benefits of efficient energy storage system to consumers all over the world.
