Natural energy such as wind power and solar energy are renewable energy sources that do not emit CO2 when generating power. Supplying this natural power in a stable and efficient manner is the first step towards achieving a low carbon society.
The goal of Hitachi's renewable energy business is to utilise the power system technology and expertise that we have cultivated over the years to help disseminate wind and solar power systems.
The Hitachi Group is using its advanced technology and products to deliver wind and solar power generation with high added value. These include our independently developed wind power generator and electric converter, high-capacity power conditioner1 for a "mega solar"2 generation system, and storage batteries.
Hitachi's strength is that we can provide total system deployment, from power generation devices to control systems that stabilise power transmission and distribution networks.
Hitachi has developed downwind types of wind power generation systems, which suit the topography of Japan, with its many mountains and hills. We achieved the highest level of wind power generation in the world for this turbine type, at 2,000 kW (Hitachi survey in March 2010). At the bottom of mountains and hills, the wind blows along the topographical features. Downwind turbines use this wind efficiently. We are also developing power storage technology and our own power prioritisation and control systems. These technologies allow wind power, which is unstable because of fluctuations in wind strength, to be connected stably to the power transmission and distribution networks.

The Hitachi Group is utilising its know-how in power generation systems and power transmission and conversion systems to provide total mega solar systems. The basic structure of a solar power generation system is shown in the figure below. A solar power generation system consists of components such as the mega solar power generation cells, highly efficient power conditioners, and storage batteries. This system enables power to be transmitted stably and smoothly from the solar power generation cells to the power transmission and distribution networks.
