On October 9, 2018, the Ministry of Economy, Trade and Industry (METI) announced that it would establish a Study Group on the Ideal Approaches to New Electricity Platforms that Take Advantage of Next-Generation Technologies. The working group will discuss the potential for next generation technologies to improve Japan’s electricity grid.

Japan’s electricity grid is facing challenges such as reduced earnings due to sluggish demand, the need to implement measures to modernize aging facilities, the need to improve the resiliency of electricity systems to prepare for large-scale disasters, and efforts to utilize renewable energy as a major power source. In order to deal with these challenges, METI aims to enhance the existing electricity grid in the “3E” areas (energy security, economic efficiency, and environment), while utilizing the existing system to its full potential.

In order to address 3E, the new electricity grid is expected to have 1) multiple inexpensive electricity supply sources, operated by new business models such as ERAB[1] and peer-to-peer (P2P) to advance economic efficiency; 2) IoT systems and data processing to improve energy security through the supply and demand management; and 3) new distributed resources such as EV and storage batteries that can achieve low carbonization and are more environmentally friendly than existing grid.

These investments require significant time and resources. Therefore, METI’s study group will discuss the risks and challenges with experts to identify necessary actions for the successful transition of the electricity grid.

[1] ERAB refers to a business framework in which businesses utilize virtual power plants and the demand response program in order to provide a variety of services, including electricity adjustments, maintaining supply-demand balances, electricity-rate cuts, avoidance of output controls and other measures to their electricity customers.
