Siemens' earliest presence in Taiwan dated back to 1955 and a representative office was set up in 1970. In 1989, Siemens Limited Taiwan was formally established. Siemens currently owns two subsidiaries in Taiwan: Siemens Limited Taiwan and Osram Taiwan Co., Limited.

Over the past several decades, Siemens Limited Taiwan has been serving as an innovation partner to many heavyweight companies in Taiwan. By utilizing its close partnership with these companies as well as state-of-the-art technologies from its global innovation network, Siemens has been answering tough questions confronting Taiwan's Industry, Energy and Healthcare Sectors and has been making significant contribution to Taiwan's economy. In a nutshell, the company supports 70% of major semiconductor & TFT LCD manufacturers in Taiwan with automation solutions that support manufacturing processes. Siemens equips Taipei 101 with its building automation and security solutions and is one of the leading suppliers to Taiwan's metro systems, including Taipei Metro and Kaohsiung Metro. The company also provides fully integrated iron and steel plant solutions to Taiwan's metal industry. In addition, more than a quarter of Taiwan's power capacity is generated by Siemens equipment and the island-wide power dispatch network has been operating using an energy management system from Siemens. The company also leads in quality healthcare through its trend-setting innovations.

In face of the tough challenges arising from climate change, Siemens will continue to work closely with its Taiwan partners and will keep bringing forward the technological innovations from its Environmental Portfolio. In 2010, Siemens launched its support to Taipei 101 which aimed for the LEED-EBOM Platinum Certification in order to become the world's tallest green building. Furthermore, Siemens also provided the first polysilicon plant in Taiwan with automatic process control system to enhance the whole PV value chain and at the same time cutting 500,000 tons of CO2 emissions per year. In addition, Siemens Taiwan successfully rolled out its environmental CSR project to educate around 1,500 primary school students on the importance of energy saving and environmental care. As a Green Infrastructure Giant and Green Solution Provider, the Company is continuously focusing on energy saving and environmental care programs to pursue sustainable growth that is beneficial to everyone - Siemens itself, its Taiwan customers and partners, and the society of Taiwan as a whole.
