Selecting a wind turbine in consideration of Hitachi's production withdrawal and global

wind turbine production and development trends

【 Hitachi's production withdrawal 】

・Press release on production

withdrawal in January 2019

・In response to this, Hitachi was

excluded from candidates

【 Global trend 】

・Three years ago, the line-up of

wind turbine mainly consisted of

4 or 5 MW

・Since then, with the expansion of

offshore wind power development

plans in Europe, the size of wind

turbines has rapidly increased

・In recent years, each wind turbine

maker has announced production

of turbines for Japan (class T)
