Industial giant Hitachi has developed two new 5.2MW offshore wind turbines, the HTW5.2-136 and HTW5.2-127.
The HTW5.2-136 has a downwind configuration and features a 15% larger rotor swept area to increase output in low wind regions, the company said.
The system will start an onshore trial in October at Hitachi’s Fukashiba wind power station in Kashima port.
The company said if the trial is successful, it intends to launch the new turbine in financial year 2017.
Hitachi plans to market the HTW5.2-136 for use in light-wind regions along the coasts of Honshu, the main island of Japan.
It has increased the rated power of the unit to 5.2MW by optimizing its setup and its control programs.
The new HTW5.2-127 is an enhanced version of the HTW5.0-126, Hitachi said.
The unit will be marketed for use at windier sites, such as the coasts of Hokkaido, northern part of the Tohoku region on Honshu, and southern Kyushu, the company added.
