Japan Microgrid Energy Storage Power Generation System

How will microgrids impact Japan's Energy Future?

As microgrids appear across the country, they will play an increasingly important role alongside the grid system to deliver clean and reliable power. Japan is currently aiming for 22%-24% of its energy to be produced by renewable sources by 2030, which will include 64GW of solar power.

When did microgrids start in Japan?

The first microgrids in Japan were New Energy and Industrial Technology Development Organization-financed projects initiated in Aichi, Kyoto and Hachinohe in 2003. A variety of energy sources were tested, in particular gas engines, and their success was demonstrated in the years that followed.

Can microgrid provide electricity to 66 real residential customers?

Microgrid with VRF battery (8MWh) has successfully provided electricity to 66 real residential customers, as stand-alone power source, through distribution network on the assumption that they are disconnected from the grid during power outages because of natural disasters etc.

Does Japan need a microgrid?

The 9.0 magnitude earthquake, which hit off the coast of Sanriku, caused vast amounts of damage to Japan’s energy infrastructure, increasing the need for the project roll-out. “It has been accelerated due to the 2011 Great East Japan disaster, and about JPY45bn of funding has been granted” for further development of microgrids, says Kashiwagi.

Why are microgrid systems becoming more popular in Japan?

The success of projects such as Higashi Matsushima eco city has increased the popularity of microgrid systems in Japan. In August 2017, the Cabinet Office announced it would be increasing National Resilience Programme funding by 24%, as of April 2018.

Should battery energy storage systems be integrated into the grid?

For many renewables developers and major power users, integrating Battery Energy Storage Systems (BESS) into the grid is becoming essential to accelerate clean energy projects and make them viable. However, securing a grid connection has led to bottlenecks, with the green project pipeline increasingly congested due to limited transmission capacity.
