Smart Community Pilot Projects (FY2010  –  FY2014  [5  years])  in Japan

Reference from a presentation of NEDO (New Energy and Industrial Technology Development Organization )

In Japan, the Ministry of Economy, Trade and Industry is promoting the four verification pilots to study the way of technologies and business in the smart community.

Kitakyushu  Smart  Crea;on  Project  is  selected  as  Pilot  PJ

Summary  of  Kitakyushu  Smart  Community  Crea3on  Project

6  

Main goal is to save energy by 20% and to reduce CO2 emission by 50%.

225 families 50 business institutes

District  informa3on  for  energy  resource •  10  general  electricity  u;li;es  have  obliga;ons  and  rights  for  the  universal  electricity  

service  in  the  society's  infrastructure  in  Japan.    •  The  experimental  area  in  Kitakyushu  is  a  special  supply  area  where  is  permiTed  to  

supply  the  dedicated  demand  area  instead  of  those  above  elecricity  u;li;es.  •  Therefore  one  of  the  characteris;cs  of  this  region  is  that  it  is  possible  to  change  the  

power  rate  unit  price  by  changing  the  actual  power  contract  in  coopera;on  with  Kitakyushu  Higashida  Maeda  District  Power  Supply  Union    of  the  relevant  region.

Consumer+ producer = prosumer Demand side includes not only consumer but also producer

Demand side “Energy Management” is Big issue

Demand Side Management controlled or regulated by energy supply side

cooperation or self-regulated by demand side

Ø Kitakyushu  city  contributed  to  the  founda;on  for  industrializa;on  of  Japan  in  early  20  century.  

Ø Through  overcoming  of  severe  Environmental  Pollu;on,  Kitakyushu  is  now  on  the  road  of    the  sustainable  development  as  smart  community.  

Ø   Smart  community  pilot  project  is  going  to  be  operated  as  social  pilot  program  from  2010  to  2014.  

Ø This  ac;vity  is  supported  by  several  technologies  such  as    Energy  management  system,  Smart  meter  and  so  on.
