Elon Musk's company gives a '' little hand '' to Japanese giants
Kintetsu is responsible for connections between the Japanese cities of Osaka, Nara, Kyoto, Nagoya, Tsu, Ise and Yoshino, totaling more than 500 km of railways. Their trains have electric locomotion, feeding on the energy of a third lane. The problem is that Osaka has dealt with frequent power outages during peak demand periods, and the company has had to find a solution to keep trains running, even when the grid is down.
What Kintetsu needed was a giant set of stationary batteries, which would be supplied from the grid when there is energy and outside peak periods, and then be able to supply it in times of crisis, also serving to normalize the electricity supply to engines of trains. And there are plenty of Japanese battery suppliers, as well as Panasonic, which has an agreement with Tesla and recently with Toyota as well, and NEC, which owns two factories in partnership with Nissan (AESC). USA and in England. But the list does not stop here, as the list of battery suppliers (and just to mention the largest) also includes Sanyo, Hitachi, Furukawa and KGK.
Even Toyota, the largest and most profitable Japanese company, has a very interesting production of accumulators because it feeds all its hybrids and plug-in hybrids with them. But Kintetsu preferred to acquire the 42 Powerpack from Tesla, the American "enemy", with the desired 7 MWh capacity.
Elon Musk's company set up the entire system in just two days, which assumes as the largest stationary accumulator in Asia, but light years than Tesla installed in Australia at the Hornsdale wind farm (129 MWh, curiously with cells 2170 from Samsung), or the 80 MWh it recently sold to California.
