Microgrids in Japan
This chapter aims to present to the reader an overview of the current status of the Japanese clean energy technology, in perspective with the current Japanese Energy Policy, putting emphasis on MGs in the country and its interrelation with, and its role within the whole energy sector in Japan. The main current trends, reflected in the new revised Japanese energy policy following the Fukushima Daiichi nuclear accident, including the pilot projects in the country or carried out by Japanese companies and institutions abroad, are addressed in this chapter. The roles and characteristics of MGs can be better appreciated from the perspective of a country with strict requirements for energy reliability due to its risky location regarding natural disasters and demanding geography. It is expected that from this chapter the reader can appreciate how largely Japanese clean energy sector has changed and is now evolving in order to establish a future energy mix to achieve the targets of CO2 emission reduction, enhanced energy security and a sustainable energy generation.
