Hightlight 1 Realizing Smart Communities Case study 2: United States Ensuring a stable energy supply 2 projects in the United States

New Mexico

Japan and the U.S. are collaborating to carry out a test project.
In the state of New Mexico, Japan’s New Energy and Industrial Technology Development Organization (NEDO) and the state government are working together to advance a Japan-US smart grid collaborative project.
NEDO is cooperating with the state government at two of the five locations where the test project is being carried out, and Toshiba Group is also participating at these locations.

Meeting local residents’ needs for a stable energy supply

In 2012, as part of the project commissioned by NEDO, two U.S. sites began operation: a micro-grid test site in a commercial building in May and a smart grid test site in September.
Of these two, the smart grid test aims to ensure a stable energy supply to local communities in order to overcome the problems that are likely to occur when large amounts of renewable energy, the output of which is unstable, are injected into distribution network.
At the smart grid test site, a large number of photovoltaic power generation systems, the output of which varies according to the weather, are connected to distribution. The objective is to construct and test a system that maintains the quality of electricity by controlling the electric current through the use of large storage batteries and demand response (DR)*.
Toshiba is participating in this project as a leader in the smart grid test.

* Demand response refers to the action of end users to help balance power supply and demand by modifying their electricity usage.


We hope that Toshiba will continue to display leadership in the technological aspects of this project.

The people of this region are highly interested in renewable energy because they depend on coal for nearly half of their electricity.
This project is attracting public attention as an opportunity to provide renewable energy to the local community as well as to test smart grid technology and its various applications. Researchers from NEDO and U.S. national laboratories are hoping that the data obtained from this experiment will lead to wider use of renewable energy worldwide.

Aiming for results that will lead to real expasion of electric vehicles

Toshiba has developed a storage battery system for the North American market by applying its latest storage battery and optimization control technologies.

In this project, Toshiba applied its latest storage battery and optimization control technologies to develop a commerical electricity storage system.
In Indiana, electric vehicles (EVs) will replace combustion-engine vehicles as government cars in the future. The system developed in this project will not only support this shift but also contribute to reducing CO2 emissions while serving as a surefire measure to reduce the load on the electric power system and realize a more environmentally conscious society.
Going forward, Toshiba will work with its partner companies to conduct tests to evaluate the performance of the newly developed storage battery system and micro energy management system (μEMS*). In the future, more charging stations need to be built to facilitate the spread of EVs and Toshiba aims to make such stations environmentally conscious. The company will also actively publicize the results of the project and apply them to other projects throughout the U.S.

* μEMS is a smart grid monitoring and control system.
