No. 114: The scheduled largest environment city in the Tokyo metropolitan area (January 2, 2012)

Business trend
A plan to construct the largest environment city in a 170,000-square-meter land is in progress. This is a so-called smart city made up mainly of 1,500 apartments complete with commercial facilities and hospitals. It is based on such IT-based advanced technologies as photovoltaic generation equipment, a system to control power consumption of each household and street lighting, and car sharing. Nomura Real Estate Development and Mitsubishi Corp. will work together on this project. The 170,000-square-land is an old factory site of Asahi Glass. 

Each household will be equipped with the home energy management system (HEMS) that controls electric usage and warns about excessive usage. The city is divided into sections, each of which is connected through information network to manage and optimize power consumption. Each household will be able to purchase high-voltage power at a lower unit price as a package deal independently than the unit price it pays for low-voltage power. A photovoltaic generation system will be adopted to generate power for areas for community use. Mitsubishi Motors will help the project with the sharing system of electric vehicles. The East Japan Great Earthquake prompted companies involved in the energy business to draw plans for more efficient use of energy and formulate measures for emergency power demand.
