Environmentally Conscious Manufacturing and Services: More Products

Power Systems, Hitachi, Ltd.
Our 2 mega-Watt downwind turbines realize high power generation efficiency, capacity to cope with severe lightening and stormy or turbulent conditions, and stable output achieved by highly reliable electrical system technology, while contributing to environmental protection.

• With favorable uphill winds on the slopes of mountains and hills, generation efficiency can be improved by around 8 percent.^*1
• Stable output is achieved using active power control.
