Toshiba Corporation announced that it has supplied a traction energy storage system (TESS) for Tobu Railway Co., Ltd. The system will start operating from 22 December. TESS stores traction energy generated by decelerating trains as they enter a station and releases it as needed when trains accelerate from the station. Toshiba’s TESS is installed at Unga station on the Tobu Urban Park Line, and utilizes Toshiba’s SCiB rechargeable batteries to store regenerated power. 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.
