Toshiba Corporation's traction energy storage system (TESS) is installed at Unga Station on the Tobu Urban Park Line for Tobu Railway Co., Ltd. Toshiba's TESS utilizes Toshiba's SCiB(tm) rechargeable batteries to store regenerated power. Regenerative traction energy from train deceleration is stored in the TESS for supply as needed when trains are accelerating from the station. In addition to supporting stable supply, the system can also be optimally configured to support other applications, including traction energy loss prevention and peak demand power management.
