Decarbonization through Energy Supply

Best Practices of Smart Networks

Creating a sustainable society strongly requires every citizen 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 energy renovations 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 by using information and communication technology (ICT).
A smart energy community shares a combined heat and power (CHP) system*1, which generates heat and electricity on site, and renewable or unused energy sources to leveling energy demand so that the community can reduce peak load. The region-wide economical use of heat and electricity increases the 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.

Smart Gas Meters
Smart Gas Meters with communication function facilitate 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.
The introduction of Smart Gas 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 of Energy Use 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 charts on a special website designed for each customer so they can easily track energy consumption and effectively save energy and costs.

Building Communities as a Base of Sustainable Way of Life

Promoting Smart Energy Communities with CHP as a Key

Tokyo Gas takes into account community characteristics in building smart energy networks (SEN). The disaster-resilient and decarbonized energy supply 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 Tokyo Gas 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 its municipality Minato Ward. We first built the Smart Energy Center in the Block I and started providing heat and energy to Minato Park Shibaura, a municipal office, 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 new urban development. Moreover, we have 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.
  • *1The SEN project in the Northern District adjacent to the East Exit of Tamachi Station 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 Capability of uninterrupted power supply to disaster management base (Minato Park Shibaura) and uninterrupted heat supply to Aiiku Hospital during power outages
Power and air conditioning used in office common spaces, etc., for certain durations
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)
