Quick Take: Japan
is moving forward aggressively to become a major global player in smart
grids and smart cities. As you will read in the story below, it has
four major smart city projects, all with a significant smart grid
component. But Japan also has dozens of additional smart city
initiatives underway around the country. And a robust Japan Smart Community Alliance organization that links industry, academia and policymakers.
Japan
was a smart grid laggard until the Fukushima nuclear disaster. Now it
is full speed ahead on smart grid projects that will let it substitute
renewable energy and demand response in place of electricity from
reactors. And on the expansion of smart grids into smart cities. - Jesse Berst
The
Japanese government has been pushing initiatives in Yokohama, Toyota
City, Keihanna Science City and Kitakyushu, as well as other locations
around the country. While the projects certainly are heavy on
technologies, the overall intent is to provide a healthy economy,
sustainable growth and an environment with a high quality of life for
citizens. And citizens are expected to take a hands-on role in smart
cities development, as this excerpt outlines:
"Each
of these projects is varied and diverse, with some considering energy
and others considering EVs. However, the main aim should be to consider
the lifestyles of the citizens, which in the end will determine the form
the cities should take. Smart cities are not something that should be
tackled by just governments and corporations and then presented to
residents. The general public must also be actively involved in sharing
their own ideas and helping to formulate the cities by throwing their
wisdom into the pot."
The
Yokohama project recently embarked on a demand response deployment at
six large commercial buildings to test the effects of drawing power from
storage batteries and energy efficiency measures. Toyota City is
examining keeping the lid on power demand increases as multiple EVs are
charged, and the project also involves the use of battery storage and an
energy management system. Part of the Keihanna project is evaluating
the use of parked EVs as storage batteries combined with recycled EV
storage batteries to reduce power demand from factories. And Kitakyushu
is conducting a dynamic pricing trial with residents as part of its
Smart Communities Creation Project.
Updates on these projects are available at the Japan Smart City Portal.
The country is sharing the projects and their results through the
portal to help city planners elsewhere with their own smart cities work.
