2.  Yokohama is expected to continue to produce value of the economy, society,
culture and environment through lively activities as a large city where many
citizens and businesses gather.
 Yokohama is responsible for returning the value created and solutions to solve
urban problems to the world as a city that is supported by the supply of human

Situation of Yokohama - Challenges
 In 2030, 70% of the urban infrastructure built during the high growth
period has passed 40 years from operation.
 Production age population declines and declining birthrate and aging
population progresses. In 2030, the number of elderly people will exceed
1 million, of which 650,000 are over 75.
 After the 2000s the situation of overdischarge has continued to Tokyo
wards. (In 2016, 3860 people relocated to Tokyo Wards)

• In 2010, Yokohama was selected from METI as the "next
generation energy and social system demonstration area"
and YSCP was implemented.
• We cooperated with 34 companies such as introduction of
the system to homes and business buildings in order to
optimize the balance of energy supply and demand in
existing urban areas.
• In order to develop and continue YSCP efforts from
demonstration to implementation, we launched the
Yokohama Smart Business Association in 2015,

7. Toward the Realization of Smart City
●Full Deployment of VPP (Virtual
Power Plant) construction project
●Promotion and examination of local
production of local consumption such
as renewable energy
●”Yokohama Blue Carbon” - Focused
on the characteristics of the city
●Flexibility of energy management

 Promote efficient energy management
while trying to solve regional issues such
as disaster prevention.
 Creating an energy base utilizing city
facilities such as sewage treatment plants
and garbage incineration facilities.
• Introduce self-contained distributed power
source such as CGS and fuel cell, energy
collaboration among multiple facilities
• CGS implementation to Pacifico Yokohama
• Taisei Corporation Technology Center
• Tsunashima Sustainable Smart Town etc..
 Demonstration experiment in cooperation
with research institution, that the coastal
area of the city is CO 2 absorption source.
 Utilize CNCA

TEPCO EP utilizes the
electricity of the battery as
economical use in the range
where 3 kWh is left in the
normal state.
3 kWh of the remaining
capacity will be used in
emergency as power for
disaster prevention by
Yokohama City.
