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 17 December, 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.

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 project.
