Hitachi strengthens offshore fleet with two new 5.2MW turbines

CTBR Staff Writer Published 08 September 2016

Japanese industrial giant Hitachi has developed a 5.2MW offshore wind turbine, the HTW5.2-136, designed to increase output in light-wind regions that have annual average wind speeds below 7.5 m/s.

In addition, the company’s HTW5.0-126, which has been increased to 5.2 MW, will be released as the HTW5.2-127.

The company expects to market the HTW5.2-127 for use at windier sites averaging 10 m/s, such as the coasts of Hokkaido in the northern part of the Tohoku region on Honshu.

The HTW5.2-136 system is scheduled to start a trial run in October onshore at Hitachi’s Fukashiba wind power station, situated on the Kamisu City waterfront in Japan’s Ibaraki Prefecture.

If the trial run prove successful, Hitachi Wind Power plans to release the new system next year.

Hitachi said the Japanese government has been offering feed-in tariff since 2012 to encourage the use of low carbon energy resources.

The company noted that the presence of archipelago of islands makes it an ideal region to leverage offshore wind power, with minimum constraints on site availability and transportation.

Plans are underway to install a number of offshore wind projects. The company says that in order to produce more efficiently, the offshore wind turbines must be extremely reliable and must have higher output per turbine.

It claims that its turbine generators have a lion’s share in the Japanese market in terms of orders. A cumulative of about 250 turbines were ordered out of which 118 are already in commercial operations.

The 5.2MW turbine has also been selected for the Fukushima floating offshore wind farm demonstration project, which is being carried out by the Fukushima Offshore Wind Consortium.
