Japan Steel Works (JSW) has revealed plans to increase production of its J82 2 MW wind turbine at its Muroran Plant in Hokkaido to 150 units a year by 2010 from the current annual capacity of just under 100. JSW began producing wind turbines in 2006 but has ambitions to overtake Mitsubishi Heavy as Japan's top domestic wind turbine manufacturer. The J82 turbine is relatively unusual in that it connects the rotor directly to a permanent magnet generator through a long drivetrain without the intermediary of a gearbox. The company says it was developed from European technology. It is considering future expansions of its manufacturing capacity, with a view to making turbines a key pillar of the firm's business.
