Importance of Renewable Energy in Japan

Renewable Energy :

� Contributes to solving global warning

� Reduces import dependency through energy diversification (energy security)

� Contributes to creating new industries and jobs

However, the introduction of renewable energy systems always involves issues such as output

instability, high costs, and site constraints.

Issues for Large-scale Renewable Integration

Power FluctuationSuppression

Surplus Power Management

Transmission Capacity

Enhancement


Governmental Support Actions

1. FY2012 Large-scale Storage Battery System Demonstration Project (by METI)

� Hokkaido Electric Power Co. and Sumitomo Electric Industries:15MW-60MWh Redox Flow Battery

� Tohoku Electric Power Co.: 40MW-20MWh Li-ion Battery

2. Transmission Network Enhancement Demonstration Project for Wind Power Generation (by METI)

3. Development of Large Scale Energy Storage System with High-safety (by NEDO)

Battery Energy Storage is a key technology for the renewable energy introduction to the grids

METI: Minister of Economy, Trade and IndustryNEDO: New Energy and Industrial Technology Development Organization
