What Toshiba Mitsubishi-Electric Industrial Systems Corporation does

Toshiba Mitsubishi-Electric Industrial Systems Corporation (株式会社TMEIC) is a privately held 50/50 joint venture between Toshiba Corporation and Mitsubishi Electric Corporation, established in October 2003 to integrate the parents' industrial systems divisions. The company designs, develops, and engineers power electronics, rotating machinery, and control systems for global industrial customers, with its core product portfolio anchored by the TMdrive family of variable frequency drives spanning low voltage (TMdrive-10e2) through ultra-high power medium voltage (TMdrive-XL85, rated up to 7.2 kV and 120 MVA), 21-H/21-G/21-VLL series industrial motors up to 23,000 kW, photovoltaic power conditioning systems (the first 1,000 kW PV inverter globally; first UL-certified 1,500V utility-scale PV inverter in the US; over 50 GW shipped), and integrated port automation suites (Maxspeed crane control installed in 1,000+ units, Maxview vision systems, MaxShorePower shore power, Hybrid-Power Guardian). The company reports ISO 9001, ISO 14001, and ISO 45001 certifications at the Japan entity, holds CE marking and UL/IECEx listings on key drive products, and operates a Power Conversion Laboratory in Virginia, USA.

TMEIC operates a direct enterprise field sales model with custom-engineered solutions priced via quote on multi-year contracts. Revenue is generated through three streams: (i) project-based hardware sales of VFDs, motors, generators, PV inverters, and specialized power electronics tied to customer capex cycles in metals, ports, energy, and manufacturing; (ii) commissioning, field service, renewal parts, training, and 24/7 emergency support generating lifecycle recurring revenue across the 20+ year installed-base MTBF; and (iii) automation, software (TMdrive-Navigator), and energy management solutions including battery energy storage systems, shore power, and hybrid power systems. Manufacturing is distributed across Japan (Fuchu, Yokohama/Kawasaki, Kobe, Nagasaki), the United States (Katy, Texas PV-PCS plant — mass production since October 2024/2025), India (Tumkur), and China (Shanghai, Guangzhou), with 18+ subsidiaries and regional offices across the Americas, Europe, China, India, and Southeast Asia, and a global workforce of 5,000+ (5,272 in Japan as of March 31, 2025).

In fiscal year 2024 TMEIC achieved record-high revenue and profit on a global basis, with orders exceeding ¥400 billion for the first time. The company launched the Growth20 management vision to 2030 in 2023 and rebranded the legal entity to 株式会社TMEIC in April 2024. Strategic priorities include port electrification (E-Tanker mobile charging solution launched May 2026), grid-scale battery energy storage (150 MW PCS contract with Tokyo Gas/HDRE in Aomori Prefecture, expanding to 340 MW combined contracted capacity), hydrogen production (IGBT rectifier with initial orders for demonstration plants), and steelmaking decarbonization (CleanArc arc-furnace power supply).
