Many may recall the "rolling blackouts" in Kanto region during the summer of 2011 – just after the Fukushima nuclear disaster. TEPCO was facing serious electricity shortages across the Tokyo Metropolitan Area, as supply-side resources (conventional generators) were damaged or not available. TEPCO had to use demand-side resources – curtailment of loads – to balance supply-and-demand and keep the lights on. This was Demand Response (DR) on a forced and uncompensated basis.
Six years on, TEPCO Power Grid, KEPCO, and Kyushu EPCO now use DR resources to maintain grid reliability and compensate participants. Approximately 1 GW has been “aggregated” by companies specializing in gathering demand-side resources (from commercial and industrial customers), allowing customers to get paid for curbing their consumption at peak times. The GOJ plans to grow this market by 10x to 6~7% of peak demand – equivalent to deregulated markets in North American and Europe. In addition, Distributed Energy Resources (DER) such as Photovoltaics (PV), Battery Storage Systems, Combined Heat & Power (CHPs), and Electric Vehicles (EVs) are expected to play a significant role in Japan’s future wholesale markets. Since aggregation of DERs is equivalent to conventional generators, it’s also known as a Virtual Power Plant (VPP).
The ACCJ Energy Committee welcomes the following leading figures as guest speakers to share the current status and future outlook of Energy Resource Aggregation Business in Japan.
Yasuhiro Sakuma, Deputy Director, Advanced Energy Systems and Structure Division, Agency of Natural Resource and Energy, METI
Hideo Ishii, Ph.D. Professor, Advanced Collaborative Research Organization for Smart Society (ACROSS), Waseda University
Akio Uchida, Chairman, Demand Response Council
This event is an unprecedented chance to learn more directly from the architects of Japan’s DR and VPP plans going forward. Come hear about Japan’s flexible energy future, in which grid transformation, greater variation in customer choices, and integration of a wider variety of distributed energy resources (storage as well as supply-side AND demand-side resources) will define Japan’s energy future.
