Japan - U.S. Collaborative Smart Grid
1. Introduction
During the period between 2011 and 2016, there had been a smart
community project called JUMPSmartMaui (JSM) held in the island of
Maui, Hawaii, U.S. With the objective of effective utilization of
renewable energy that had been penetrating on a larger scale and
widespread deployment of electric vehicles (EVs), a smart community
was constructed by Hawaiian and Japanese stakeholders, headed by the
New Energy and Industrial Technology Development Organization
(NEDO) of Japan.
Smart community is a social system that integrates advanced
environmental and energy technologies and provides citizens belonging
to the community with sustainable, safe and secure society. In this
context, it is important to have a perspective of what value had been
provided to citizens by the smart community. Based on this viewpoint,
this report summarizes suggestions for future smart community
development derived from the activities and results of
JUMPSmartMaui, especially from the engagement of citizens (i.e.

2. Overview of JUMPSmartMaui project
2.1 Energy situation in Hawaii
The island of Maui, which provided the stage for
JUMPSmartMaui, is the second largest island in Hawaii with an area of
approximately 1,884 km2
, a population of approximately 145,000 and
tourism as its major industry. The island’s electricity is supplied by Maui
Electric Company Inc. (MECO) which has the peak demand of about
205 MW.
The islands of Hawaii including Maui have a conspicuous feature
in terms of energy, which is extremely high energy cost. Figure 2 shows
retail electricity prices by state. It is indicated that the price in Hawaii is
significantly high compared with other states in the mainland. This is
due to the situation that Hawaii largely depends on imported fossil fuel
(especially oil) because of the geographical factor of being consisted of
remote islands.
Under such energy scene and with the rise in environmental
awareness, the Hawaii Clean Energy Initiative (HCEI) was launched in
the State of Hawaii in 2008 and the Renewable Portfolio Standard
(RPS) was formalized in 2009. The RPS target was set to 15% by 2015,
25% by 2020 and 40% by 2030. Later, the bill, House Bill 623 (HB
623) set more ambitious goal of 30% RPS by 2020, 70% by 2040 and
100% by 2045.
The State Hawaii has been accelerating introduction of renewable
energy. At the same time, it is placing importance on the promotion of
EV (electric vehicle) as a solution to move away from the dependence
on fossil fuels, particularly oil, and established EV promoting acts
including the following:
