New trend of Energy policy and Influence on an energy
system design of Smart Community

Reconsideration of “National Energy Primary Supply Plan” particularly Nuclear energy used to be “53% by 2030”
Accelerate of Renewable Energy
Utilize Independent Power Producer at most
Generation Cost re-calculation for each energy such as Nuclear, Gas, Charcoal, Wind Farm, PV, Geo-thermal
The point of Energy Policy in Japan
Small scale distributed gas co-generation
Drastic energy save and peak cut at demand side
Electric price menu for peak cut/shift by having incentive

National Project “KEIHANNA SC Trial”
Project term is 5 years FIY2010~2014 METI* budget
Community Energy management which aims “carbon reduction"," demand reduction” and ”peak cut/shift” with CEMS, HEMS/BEMS, community battery and EV.
How community reduce carbon
How community contribute to demand response request from utility
How community reduce energy consumption
How to realize modal shift
