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
