Hitachi delays 5MW turbine plans

Hitachi has slightly delayed plans to set up its first 5MW downwind turbine, and now expects to install a single machine next to the port of Kashima, eastern Japan, by the end of September.

Last November, the company said it would will start installing its first 5MW offshore turbine off the coast of eastern Japan by the end of March 2014. Demonstration tests were initially scheduled to begin in May or June.

A company spokesperson tells Recharge that the turbine is still being built, but did not reveal the reason for the delay.

Hitachi hopes to participate in SB Energy’s plan to develop a 100MW offshore wind farm off Kashima, but “nothing has been decided yet,” the spokesperson says.

It still appears on track to start selling its HTW5.0-126 turbine — featuring a permanent-magnet generator (PMG), medium-speed gearbox and 126-metre-diameter blade span — in Japan in fiscal 2015.

Last February, it started running a new 2MW turbine, fitted with an 86-metre rotor for low wind speeds, in Tainai, Niigata prefecture.
