Eco city kitakyushu Kitakyushu’s Smart Community Project and its Contribution towards CO2 Reduction

Yuji KATO CLAIR Singapore (The Japan Council of Local Authorities for International Relations)

Introduction to Kitakyushu

• Area : 500 ㎢ • Population : 1 million • Tokyo = Shanghai = 1,000 ㎞

From “Grey City” to “Green City” Present Environment

Pollution in 1960s “Seven Colors Skies and Seas”

Smart Community Project The stage for the project : Higashida area in Kitakyushu

Outline of the Higashida area (as of Mar, 2013) Area :120ha 　 Residents : 1,000 Companies : 50 　 Employees: 6,000

Smart Community Project Objective To implement pilot program (field trial) that aims to achieve efficient energy management and CO2 reduction of residents and c ompanies residing within the area.

Main Schemes • Scheme 1 : Eco friendly power supply • Scheme 2 : Energy Visualization • Scheme 3 : Dynamic pricing

Project Commencement : FY 2010

Smart Community Project

Targets 1. CO2 reduction : 50% 2. Peak cut* : 15% *Reducing electricity consumption within the area during peak times (in comparison with the average consumption rate with other areas in the city).

Peak time = periods of time in a day where most electricity is being used summer : mid day winter : morning and night

Smart Community Project Scheme 1 : Eco friendly power supply Cogeneration

Renewable energy

(Produces electricity and heat)

(hydrogen, solar, wind)

Utilize waste heat in factories

Power supply to Higashida area

Smart Community Project Scheme 2 : Energy Visualization

Smart meter : measure electricity consumption hour by hour

In-house display : placed in each household.

Displays electricity consumption and energy-saving tips

Smart Community Project Scheme 3 : Dynamic pricing Change price of electricity to 1. meet supply and demand 2. shift/cut consumption “peaks”

The World’s First!!

Smart Community Project Result② : Peak Cut Periods

2012 Summer

Reduction rate of electricity － 18.1% consumption in Peak time ～－ 22.2%

2012 Winter

2013 Summer

－ 18.1% ～－ 21.1%

－ 18.8% ～－ 20.2%

(compare to general area)

Electricity consumption (peak time) reduced by about 20%.

Smart Community Project Outcomes from result Local government policies (visualization and dynamic pricing)

Change Residentâ&#x20AC;&#x2122;s mindset and behavior

Big impact Energy saving and CO2 reduction

Smart Community Project Participation & Involvement Feedbacks from Residents “Easy to know how we could contribute to energy saving.”

“I became to be aware of my electricity usage.”

“I look forward to next month’s electricity bills.”

Smart Community Project Next step : Expand to overseas Exporting infrastructure to Surabaya industrial complexes, utilizing tech nologies and expertise gained from the Smart Community Project.
