The verified answer
As of Oct 2026, DEPLOY verifies TEPCO: 1 model, 1 active incident. 2 sources back the record.
Overview
Tokyo Electric Power Company Holdings (TEPCO) is Japan's largest electric utility and the operator of the Fukushima Daiichi Nuclear Power Station, where it pioneers robotic decommissioning using remotely operated and Spot quadruped robots from Boston Dynamics. Since the 2011 disaster, TEPCO has deployed over 16 types of robots for fuel debris retrieval, radiation surveying, and facility inspection — including the Telesco telescopic device that extracted the first sample of melted fuel in 2024. Its subsidiary TEPCO Power Grid became the first Japanese power company to introduce an arm-equipped quadruped robot for underground substation inspections in 2025.
