Tatung Company

What Tatung Company does

Tatung Company (大同股份有限公司, TPE: 2371) is a Taiwan-headquartered, publicly traded industrial conglomerate founded in 1949, operating through four primary business groups spanning heavy electrical equipment, consumer electronics and home appliances, system integration, and new energy solutions, supported by a 10,000+ employee base. Its core technology platform spans power transmission and distribution infrastructure (transformers, switchgears, prefabricated substations, power cables, LAN cables, fiber optic cables), motors and diesel generating sets, and a fast-growing EV powertrain line featuring proprietary "hairpin" motor technology that achieves 97% direct-drive efficiency across 150kW commercial-logistics to 340kW intercity-transport power ratings. The new energy group, anchored by subsidiary Tatung Forever Energy (大同智能, 大同永續能源) and branded Tatung Smart Energy, delivers energy storage systems, microgrids, solar PV systems, smart meter/AMI infrastructure, and energy management systems for utility, industrial, commercial, and public-sector customers.

Tatung monetizes predominantly through hardware sales across its power equipment, motor/generator, cable, and consumer appliance lines, complemented by professional services revenue from system integration, ICT outsourcing, cloud applications, and business intelligence projects. GTM is enterprise field sales through specialized divisions, with an owned e-commerce storefront (e同購) for consumer appliances and an overseas ordering system for international customers. Its customer base spans utilities and grid operators, EV bus/commercial-vehicle OEMs, industrial and commercial facilities, hospitals, universities, and household consumers, with notable reference deployments including nearly 1,000 electric bus systems operating in Taiwan and recurring green-electricity procurement contracts with hospitals and manufacturers.

The company is currently pivoting toward international expansion - specifically targeting EV powertrain supply chain localization in Thailand and India and renewable energy installations across Pacific island nations via Taiwan's ICDF - while simultaneously launching an AI transformation initiative under new executive leadership. Diversification across legacy industrial infrastructure (transformers, motors, cables), high-growth EV components, and emerging smart energy services gives Tatung multiple, partially uncorrelated growth vectors anchored by 70+ years of motor manufacturing expertise and a deeply embedded brand in the Taiwan market.
