Hitachi Commences Demonstration Site for Japan-U.S. Island Grid Project in Hawaii
MAUI, Hawaii --(Business Wire)--
Ltd. (TSE: 6501, "Hitachi (News - Alert)") today announced that it has begun
operations on the demonstration site for the Japan-U.S.
Island Grid Project on Maui Island, Hawaii, in collaboration with
Energy and Industrial Technology Development Organization ("NEDO"), Mizuho
Bank, Ltd. ("Mizuho Bank") and Cyber
Defense Institute, Inc. ("Cyber Defense Institute").

The goal of this Project, which is based on an agreement between the
American and Japanese governments, will be to demonstrate smart grid
technologies that will enable the efficient use of renewable energy and
will contribute to the implementation of a low-carbon social
infrastructure system in island regions. The demonstration site has been
designed to respond to the rapidly changing demands in the renewable
energy market, which will be made possible through the use of electric
vehicles (EV) and other innovative technologies.
The demonstration site is scheduled to be in operation from December 17,
2013, through the end of March 2015. Based on the results of analysis
and evaluations, the goal of this site is to build a business model for
future "Island Smart Grids" that will be built in other sub-tropical
regions with environmental conditions similar to Maui.
According to Maui
Electric Company, in 2012, renewable energy accounted for 21% of the
total energy supply on the Hawaiian island of Maui, and current plans
call for at least 40% of increased demand for electrical power
throughout the entire state of Hawaii to be met with the use of
renewable energy by 2030. In the backdrop of the growing adoption of
renewable energy, in 2011, NEDO initiated the Japan-U.S.
Island Grid Project (commonly referred to as the "JUMPSmartMaui"
Project) to resolve the issues related to the use of these new energy
sources. As the company with primary responsibility for this Project,
Hitachi oversees all aspects of Project activities, and has been working
on the construction of the demonstration site in collaboration with the
Mizuho Bnk and the Cyber
Defense Institute, along with the state
of Hawaii, the County
of Maui, Hawaiian
Electric Industries, Inc., the University
of Hawaii, and the American national research laboratories.
In order to create a smart grid for island regions using EV, Hitachi has
established an EV Energy Control Center (EVECC), and has already put in
place a Distribution Management System (DMS) to control power
distribution systems in the Kihei district on the south side of Maui,
and the Energy Management System-Plus (EMS-Plus). The goal is to control
the balance of supply and demand in electric power systems and support
the efficient operations of renewable energy. These systems also
incorporate the Direct Load Control (DLC) technology for the direct
control of devices in users' homes, which was introduced in order to
minimize the effects of fluctuations in the supply of renewable energy.
Up until now, Hitachi has involved the public to be part of the
demonstration on a volunteer basis and participate in the demonstrations
primarily focused on the EV users on the island of Maui. Also, regular
residents/consumers interested in participating in control
demonstrations for electric water heaters installed in private
residences in the Kihei area will also be involved in the demonstration.
Hitachi has also promoted the installation of rapid EV charging
stations, as well as complying with American cyber security standards,
in order to ensure the safety of systems operating throughout the
demonstration site and throughout the duration of the demonstration
To date, Hitachi had already confirmed approximately 150 volunteers as
users of EV, and confirmed approximately 40 residential households
interested in participating in control demonstration using electric
water heaters. In order to promote further demonstration, the company
plans to secure 200 volunteers as EV users and 40 volunteer user
households in total. Already, 20 EV charging stands have been installed
at five existing rapid EV charging stations, and there are plans to
establish a total of 20 charging stations in the future.
Today, an opening ceremony was held on Maui Island to coincide with the
launch of the site operations. Attendees at the ceremony included Mr.
Hiroshi Kuniyoshi, Executive Director at NEDO; Mr. Koji Tanaka,
Executive Vice President and Executive Officer at Hitachi; Mr. Kosuke
Nakamura, Managing Executive Officer at Mizuho Bank; and Mr. Makoto
Kubota, President of Cyber Defense Institute. Also, Mr. Alan M. Arakawa,
Mayor of Maui County, and Ms. Sharon Suzuki, President of Maui Electric
Company attended the ceremony.
On-site demonstrations will use wind power generation systems and power
systems installed on the island of Maui, which generate a total of
72,000 kW of power. These power systems leverage information
technologies to demonstrate controls for the power distribution systems
and the load on the consumer side, as well as systems for controlling EV
operations and charging, including various types of rapid charging
devices. Operations at the demonstration site are scheduled to continue
until March 2015, and following this period, subsequent studies and
discussions will be conducted for implementing new business models based
on the results of these demonstrations and evaluations.
Details of the Japan-U.S. Island Grid Project on Maui Island
In November 2009, an agreement was reached during the Japan-U.S. Summit
dedicated to the "Japan/U.S. Clean Energy (News - Alert) Technology Collaboration," and
in June 2010, a "Memorandum of Cooperation (MOC) highlighting the
Hawaii-Okinawa Partnership on Clean and Efficient Energy Development and
Deployment" was completed by the Japanese Ministry of Economy, Trade and
Industry, the U.S. Department of Energy, Okinawa Prefecture, and the
State of Hawaii.
Upon completion of these agreements, NEDO completed a basic agreement
with the State of Hawaii in November 2011, and completed a similar
agreement with Maui County in June 2013.
Toward the realization of Island Grids that utilize EV for the more
efficient use of renewable energy, Hitachi will strive to achieve
integrated energy management in this island region, by linking the
Distribution Management System in Kihei with the EVECC. Furthermore,
EVECC allow volunteers with their PCs and smart phones to monitor the
status of EV charging and automatically adjust the timing of charging
startup. With this in mind, the Project will also serve to verify
mechanisms for efficiently absorbing excess electric power from
renewable energy sources into EV.
The Distribution Management System installed in Kihei will use the
Direct Load Control (DLC) technology to stabilize power distribution
systems and minimize the effects of fluctuations in power output
resulting from increased ratios of renewable energy by controlling
frequency support*1, rechargeable batteries, µ (micro) DMS*2
and consumer devices.
This configuration will also enable autonomous control in the
low-voltage systems for distributing power to homes, commercial
facilities, and other buildings through µDMS. Additionally, it will make
it possible to control photovoltaic output and voltage as well as
emergency load, in order to prevent transformer overload. Through this
Project, Hitachi will verify the effects on the stabilization of power
distribution systems achieved by linking DMS and µDMS and by
implementing controls on various levels. At the same time, the Project
verifies the optimal energy management strategy for the system as a
whole, including Direct Load Control and reduction of frequency
*1 Frequency Support Control: Rapid fluctuations in output from wind
power generation and other forms of renewable energy are expressed in
the form of changes to the frequency of electric power systems. When
frequencies appear likely to deviate from specified values, the
Distribution Management System reduces frequency fluctuations by
isolating non-urgent load and adjusting battery charge and discharge
*2 µDMS: As a low-level DMS installed in low voltage transformers to
control entire power distribution systems, µDMS controls household
devices using bidirectional communication between the DMS and the low
voltage power distribution systems.
