The city of Yokohama believes that its mission and role in history is to deliver its long standing expertise in sustainable development to Japan including the disaster stricken areas and the world. To realize a city where "people want to live" and "everyone is active," and to improve the quality of life in three areas, environmental, social and economic, by meeting challenges such as global warming, energy conservation and the super-aging society.
The city is collaborating with the private sector (Accenture, Tokyo Gas, Toshiba, Nissan Motor, Panasonic, Meidensha, TEPCO, etc.) to work on various projects such as introduction of renewable energy, energy management of households, buildings and local communities and next generation transportation systems.
The Yokohama Smart City Project (YSCP) in an effort to develop an energy management system (EMS) in managing energy and making energy use visible. There are a number of different types of EMS: HEMS for houses, HEMS for residential complexes, HEMS for apartments, integrated BEMS, and FEMS, which optimally control factory operation. Integrated BEMS offer group management of BEMS for office buildings and commercial facilities.
CEMS brings together elements including the electric vehicles (EV) for charging and discharging verifications, charging stations, and the SCADA storage batteries that contribute to system stabilization, which will form the nucleus of next-generation transport systems.
The City of Yokohama aims to be recognized as Japan’s Low Carbon Eco-Model City, in reality and in name, in the future by deploying activities carried out under this concept to the whole city.
By means of optimal linking of the EMS, centering on the CEMS, the city is creating infrastructure that will facilitate the large-scale introduction of renewable energies, for example by offsetting the instability of weather-sensitive photovoltaic (PV) generation. At the same time, the city is conducting large-scale verifications of demand response (DR).
