Contribution to the Environment

Promoting Smart Networks

Creating a sustainable society strongly requires society as a whole to address issues such as saving power and ensuring energy security in addition to the long-sought effort of reducing CO2 emissions.
As a means of solving these issues, the Tokyo Gas Group promotes the development of smart communities that wisely use energy in a heat and power supply network connecting buildings. The Group also pursues efforts to introduce smart energy use for entire buildings, including the conversion of office buildings and plants.

Promoting Community-Wide Smart Energy Use

To create smart energy communities, we construct smart energy networks that optimize energy demand and supply through a heat and electricity network and energy management making use of information and communication technology (ICT).
A smart energy community combines a combined heat and power (CHP) system*, which generates and consumes heat and electricity locally, with the use of renewable or unused energy sources and adjusts energy demand so that the community can reduce the peak load. The region-wide economical use of heat and electricity increases energy efficiency of the entire community and sustains business activities and everyday life in the event of a power outage while enhancing the value of urban living.
Development of smart energy communities is increasing in the Tokyo area in line with national and local government policies.

*Gas engine-based CHP systems generate electricity and recover waste heat generated as a by-product.

   
Smart Meters
Communications-enabled gas meters allow for measuring and controlling the flow of gas. Besides their incorporation into home energy management systems, they are used for externally confirming whether gas appliances have been turned off and remotely shutting off gas.
We are conducting tests and developing technologies so that they can be introduced into every home.
The introduction of smart meters is intended to increase customer convenience and provide added value through the use of measured data, in addition to improving operational efficiency.

Promoting Visualization at Office Buildings

TG Green Monitor to Visualize Energy Use

The TG Green Monitor service measures energy use at customer sites and visualizes the usage of gas and electricity as well as the status of equipment operation. The service allows customers to view data shown in simple graphs on a special website designed for each customer so they can easily track energy consumption and effectively save energy and costs.

Building Communities and a Way of Life that Is Safe and Secure

Putting CHP Systems at the Core of Smart Energy Communities

Tokyo Gas takes into account community characteristics in building smart energy networks. The disaster-resilient supply of low-carbon energy contributes to developing sustainable communities with superb environmental protection as well as disaster preparedness and management.
 
Developing a SEN in the Northern District Adjacent to the East Exit of Tamachi Station
The Group is constructing a smart energy network (SEN) in the Northern District adjacent to the East Exit of Tamachi Station*1 in Tokyo in collaboration with Minato Ward. We first built the Smart Energy Center in the Block I and started providing heat and energy to Minato Park Shibaura, a public facility, Aiiku Hospital and a child welfare facility in November 2014. This was the first project in Japan to introduce a SEN as part of the development of a new community. We have also introduced a SEN at msb Tamachi in the Block II-2 (West area), which was partly opened in April 2018. We built the Block II Smart Energy Center in step with this development of a business complex at a Tokyo Gas-owned site. We hope to reduce CO2 emissions in the entire North District by 30% below 2005 levels through the coordinated operation of the two Smart Energy Centers.

*1 The SEN project received the Minister of Economy, Trade and Industry Award in the Successful Case of Energy Conservation category at the Energy Conservation Grand Prize awards in fiscal 2016.


Main Features of a SEN in the Northern District Adjacent to the East Exit of Tamachi Station
Linkages among multiple facilities with different purposes Public facility, hospital, office, commercial facility, etc. 
Maximum adoption and effective use of renewables, untapped energy, etc. Use of solar heat and heat of underground tunnel water for air conditioning (first application in Japan for district heating)
Contribution to BCPs Capable of uninterrupted power supply to disaster management base (Minato Park Shibaura) and uninterrupted heat supply to Aiiku Hospital during power outages
Power, air conditioning used in an office common space, etc., for a certain duration 
Optimal supply/demand control by SENEMS*2 Optimization for area-wide heat and power according to outside air conditions and energy usage (first in Japan)
