BEMAC, as majority shareholder, together with Mitsui have entered into a share purchase agreement to acquire 100% of the shares of The Switch from Yaskawa Europe Holding AB (a wholly owned subsidiary of YASKAWA Electric Corporation). The Switch possesses world-class technology in MW-class PMMs, DC distribution solutions, high-power AC drives and high-speed induction motors, with a track record of delivering more than 22 GW of these products primarily for wind power and marine applications. In recent years, with a focus on achieving “zero greenhouse gas emissions by around 2050” as advocated by the International Maritime Organization, the demand for large-sized vessel shaft generators and propulsion motors for electric propulsion ships has been increasing.

Since delivering the world’s first megawatt-class PM shaft generator in 2015, The Switch is currently the market leader in PM shaft generator markets, with its machine and drives product portfolio ranging from below 1 MW to over 10 MW. These variable speed shaft generators are typically used in various large vessels, such as LNG carriers, container vessels, car carriers and different types of tankers, where they enable significant fuel savings and emissions reductions, contributing to the shipping industry’s green transition. The Switch DC-Hub is an efficient and future-flexible marine electrification solution for hybrid and fully electric vessels with multiple energy sources like batteries and fuel cells. Furthermore, The Switch’s high-speed induction motors are used in industrial plants for blowers, compressors and more, offering solutions that enable high efficiency, compact design, and gearbox-free applications.

Mitsui has a diverse business portfolio encompassing shipping and energy development, among others. The combination of both companies’ business foundations and technologies is expected to accelerate The Switch’s business growth and contribute to greenhouse gas reduction efforts.
