Contribution to Local Communities

Safe and Secure Ways of Life and Urban Development

The Tokyo Gas Group is developing an SEN in the north district of

Tamachi Station east exit (East area, Minato-ku, Tokyo) in partnership with

the Minato ward authorities with the goal of reducing the area’s carbon

footprint and making it more disaster resilient. Supplies of heat and

power have been progressively rolled out to three facilities—Minato Park

Shibaura (a public facility), Aiiku Hospital, and a childcare support

facility—since November 2014. The project is the first new urban

development project in Japan to incorporate development of an SEN. In

October 2014, the decision was made to proceed with the TGMM

Shibaura Project (provisional name) to develop Block II-2 (West area) in

the north district of Tamachi Station east exit. This will create a multi-

purpose business center on land owned by the company. In future,

dependent on the state of development in the district, we will build a

second smart energy center and operate it in tandem with the first, thus

reducing CO2 emissions in the entire area of the north district of Tamachi

Station east exit by some 45% relative to 1990.

We are pursuing the “development of smart energy communities” that use energy smarter by connecting buildings in the community with a heat and electric power network.

We will achieve this by constructing smart energy networks (SEN). SEN have a gas cogeneration system (CGS) at their core, which is complemented by creating the heat and power network to be used in the community, and by making maximum use of renewable and untapped energy resources. Information and Communication Technology (ICT) is used to precisely manage these energies and the state of demand-side use to optimize energy supply and demand. Taking into account local characteristics, we will contribute to creating communities that are both more environmentally friendly and disaster resilient.

The Tokyo Gas Group is pursuing urban development with the potential

to last well into the 22nd century in a redevelopment area located

around land the Group holds in the Toyosu wharf district of Tokyo’s

Koto-ku. This is a project called “Tokyo Smart City TOYOSU 22.” Under this

project, we are undertaking futuristic urban development guided by

three conceptions of “smartness”—“smart energy,” “smart green,” and

“smart community,” from a long-term perspective looking beyond the

Tokyo 2020 Olympics and Paralympics, which is a high-quality

development to raise the value and appeal of the area.　

Work began in July 2014 on construction of a smart energy center in

Zone 4 (see figure below), owned by Tokyo Gas Site Development Co.,

Ltd., in preparation for developing a Toyosu wharf district SEN. This will

be the second SEN Tokyo Gas has developed in an urban redevelopment

district, the first being a SEN in the north district of Tamachi Station east

exit (see p. 39). The goal is to commence operation in May 2016. The new

smart energy center will be equipped with one of the world’s most

efficient gas cogeneration systems. It will supply electric power to the

Toyosu wholesale market, and waste heat will be used at the center itself.

Environmental friendliness will be enhanced by adopting gas pressure

differential power generation using gas supply pressure. By giving the

CGS blackout start functionality*1, laying independent power lines*2, and

employing disaster-resistant medium-pressure gas pipelines, we will

create a system that is capable of supplying uninterrupted heat and

electricity even during a power outage or other emergency, thus

enhancing the district’s disaster resilience. The network will also have a

“SENEMS”*3 for centrally managing and controlling energy throughout

the district using ICT. This will make it possible to control air conditioning

in real time and visualize energy use, which will cultivate greater

environmental awareness among building users. Following completion,

the heat and power network will be progressively expanded in line with

the state of urban development of Zones 4 and 2.

*1 Capability to independently restart the generator during a power outage.

*2 Power lines laid independently by an operator. They can be used at a customer’s

discretion when grid power has been interrupted.

*3 Smart Energy Network Energy Management System.

We will develop “smart energy networks” to create low-carbon, disaster-resilient communities that can contribute to the

realization of a sustainable society. We will also leverage every communication opportunity to work with local residents

through our involvement in disaster training programs and other events.

■ SEN Development in the Toyosu wharf district

■ Started supplies of heat and power at SEN in the north district of Tamachi Station east exit

Our local branch offices and our corporate museums provide and share information on disaster countermeasures at disaster prevention events to

enable us to coordinate smoothly with local authorities and communities during disasters. For example, at one local training event for disaster

prevention hosted by a local authority, we explained how to reset a gas meter after it shuts off during an earthquake with a seismic intensity of 5 or

more. We also provided other useful information to enhance the safety and security of our customers in their daily lives. Since 2006 we have also

developed our own disaster prevention events for families

with the aim of enhancing the disaster prevention

capabilities of local communities. These “Iza! Kaeru Caravan!”

events are jointly operated with Plus Arts (NPO), and are

offered primarily at our corporate museums and showrooms.

At these events, family members can acquire the skills and

knowledge they need to prevent disasters, all presented in

an enjoyable format.

Highlights of Key Activities

As a company involved with energy, Tokyo Gas wants the children upon

whose shoulders the future rests to know just how important energy and

the environment are. To that end, we have been supporting school

education since 2002. Our main activities include special classes taught

onsite in the schools by our own employees, the hosting of training

sessions for teachers, and the provision of information through field trip

facilities, teaching materials, and learning websites.

Our special classes are taught by employees who visit schools to

teach alongside teachers and provide them with teaching materials that

reflect our unique expertise as an energy provider and are tailored to fit

into their teaching plans. In November 2014, the total number of children

who had taken part in these classes passed the one million mark (rising

to 1,019,298 pupils attending 33,832 classes by the end of March 2015).

We also organize training workshops for the teachers themselves in

order to deepen their knowledge of energy and environmental issues

and encourage them to consider how best to convey this knowledge to

children. These workshops are held in Tokyo and three prefectures

(Kanagawa, Chiba, and Saitama) upon request from boards of education

and study groups on education, with 1,273 teachers taking part in fiscal

2014.

Outside of school itself, we host field trips to our Gas Science Museum

and provide information for teachers and children via our “Odoroki!

Naruhodo! Gas World” educational website in order to broaden and

deepen children’s education and give them an opportunity to think

about energy and the part it plays in their lives.

Tokyo Gas’s Gas Science Museum was merged with our Energy and Earth

Exploratorium (closed in March 2014) and re-launched in April 2014 as

our core showcase for energy and environmental matters with a natural

gas theme. The museum plays host to all kinds of programs, including

interactive exhibitions that are designed to be touched and felt as well as

seen, as well as science shows and quizzes that build on what visitors

learn from the exhibits. In fiscal 2014, the museum attracted 264,122

visitors, including local residents, people from local authorities and

companies, as well as elementary school groups.

As a company that has long dealt with "fire" in all its manifestations, we

are actively engaged in programs that reveal the value and benefits of

fire from gas in our daily lives. As part of our next generation youth

education activities, we have been working since 2012 to expand our

participatory “HIIKU” fire education program. The program’s aim is to offer

people an opportunity to learn more about fire and how to use it

properly, to develop their disaster survival skills, and to help them find

ways to enrich their lives through direct experience with the many

benefits afforded by fire. The program attracted some 2,800 participants

in fiscal 2014.

Launched in fiscal 2013 to bring our environmental

contributions closer to customers in their own communities, the

Kininaru Project (“Tokyo Gas Tree Planting Project”) supports

public programs to enhance local green space by making

donations to local governments according to sales of our

environmental products, and by involving group employees

and their families in environmental activities. In fiscal 2014,

donations worth ¥1,790,000 were made to “green funds” in

Tokyo, the prefectures of Kanagawa and Saitama, and the cities

of Saitama and Sodegaura based on group sales (12,625 units)

of ENE-FARM and SOLAMO during the previous fiscal year. In

activities undertaken by group employees, 100 individuals

planted 600 trees at Umi-no-Mori (“Sea Forest”) in Tokyo, and 41

individuals removed invasive plants at Koajiro-no-Tani in

Kanagawa Prefecture.

The Tokyo Gas Environment Support Fund was established in December

2007 through a grant from Tokyo Gas to the Japan Environment

Association to commemorate our reaching the 10 million customer

milestone in September 2007. Through the fund, we support non-profit,

private-sector organizations* engaged in ongoing environmental

conservation activities. In fiscal 2014, applications were received from 50

organizations. Grants worth a total of ¥10 million were provided to 16 of

these applicants further to a strict selection process by a panel including

experts. We express our gratitude to a wide range of local communities,

and will contribute to the amelioration of regional and global

environmental problems and the realization of a sustainable society.

* Organizations active in Tokyo and the prefectures of Kanagawa, Chiba, Saitama, Ibaraki, Tochigi, Gunma, Yamanashi, and Nagano.

Our cooking class program, which celebrated its centenary in 2013, offers

a variety of classes tailored to different participants and needs. These

include “Kids in the Kitchen,”* which teaches children how to cook for

themselves and to use their five senses in the process, and “La Cucina

Espressa,”* which shows how gas is uniquely suited to quickly cooking

multiple dishes at one time. All of these cooking classes incorporate an

environmentally conscious approach to eating habits that we call

“eco-cooking,”* and 2015 marked the twentieth anniversary of our

unveiling of this concept. Approximately 120,000 people took our

“eco-cooking” classes in fiscal 2014 and, equally important, we also

trained some 300 people to teach the classes. Going forward, we will

continue our efforts to enhance customers’ lifestyles and eating habits.
