- Building Systems to Reduce Carbon and Equalize Electricity Usage Based on Regional Electric Demand Forecasts
Smart Mobility & Energy Life in Toyota City (Smart Melit) is a low-carbon society system verification experiment project that is using the EDMS (Energy Data Management System) to reduce regional carbon production and equalize electricity consumption. The EDMS forecasts regional electric power supply and demand and uses solar power systems for local production and local consumption of green electricity to reduce CO2 emissions.
- Using All Electricity Generated by Solar Power for Self-Consumption with HEMS
The low-carbon society system verification experiment (Smart Melit (Smart Mobility & Energy Life in Toyota City)) project being carried out by Toyota City is moving ahead with an experiment in which all of the electricity generated by solar power generation systems can be used efficiently with HEMS (Home Energy Management Systems) that are connected to a total of 67 sub-divided residential homes. These are linked up to an EDMS (Energy Data Management System) designed to lower carbon emissions and alleviate electricity consumption throughout the entire community, and optimal control is carried out for fuel-cell battery systems and other forms of energy-related equipment.
- Making Use of Verification Experiments to Support Business Opportunities for Small- to Medium-Sized Companies
It is not only major companies like Toyota Motor Corp., Denso Corporation and Chubu Electric Power Co., Ltd. that are participating in the low-carbon society system verification experiment (Smart Melit (Smart Mobility & Energy Life in Toyota City)) project; it is also composed of members from small- to medium-sized companies. Shinmei Industry Co., Ltd. has its head office in Toyota City, Aichi Prefecture, and is involved in the production and sale of converted (remodeled) EVs. Toyota City is continuing to hold study groups in environmental and energy-related fields targeting small- to medium-sized companies that are not taking part in the verification experiment project in order to provide support for expanding their business opportunities.

About the city
A regional urban center in the north of Aichi Prefecture, Toyota City is the prefecture's largest city in terms of area and boasts its second-largest population. Toyota City is an in-land industrial city situated on the middle stretches of the Yahagi River, and is known for being a "company castle town," the location of the headquarters of Toyota Motor Corporation. As a model city for the EV&PHV Town Concept and ITS operational experiments, Toyota City has commenced the introduction of next-generation vehicles and transport systems, and is working towards the realization of a low-carbon society.
Overview of the project
This project seeks to envision the home environment in ten years' time, when there will be introduction of renewable energy and more extensive use of various energy-saving and energy storage devices. The power transfer patterns of a variety of devices, including next-generation vehicles, will be integrated and controlled by HEMS, enabling users to enjoy a pleasant and convenient low-carbon lifestyle without waste and without effort. Advancing the introduction of next-generation mobility modalities, the building of public transport infrastructure, and the presentation of new forms of transport use in tandem, we are aiming to become the city with the world's highest level of harmony between cars and people. We will use a range of energy sources including city gas and biomass, and make full use of heat and electricity. We will offer a variety of incentives to encourage citizens to engage in their own carbon-reduction activities, at the same time as making energy use visible, providing support for action, and enabling control of energy use through familiar terminal devices, making it possible to select from an optimal menu of low-carbon activities for the entire living environment with a minimum of effort.
Focusing on the household sector (residences and transport), the project seeks to identify medium-term technological issues based on an image of the household in ten years' time, when, for example, photovoltaic (PV) generation will be widespread and grid parity will have been established. Without rushing to raising the social cost, we will develop low-carbon systems that present the overall optimum at the level of the community as a whole. In concrete terms, we will offer highly convenient and satisfying incentives (such as "eco points") for activities conducted by citizens that contribute to reducing carbon (saving energy, reducing the load on the power system, making effective use of green power, etc.) in order to study the change in citizens' behavior and the magnitude of its impact. In terms of effective incentive design, in addition to introducing various devices and systems to the city, we will establish a system in which citizens obtain data on personal energy consumption and behavior to enable us to reduce carbon at the same time as ensuring the satisfaction of our citizens.
