Enhancement of Energy Security

Production of City Gas

With more now expected of natural gas following the 2011 Great East Japan Earthquake and with full liberalization of the gas and electricity retail markets unleashing major changes in Japan's energy industry, Tokyo Gas Group recognizes that the stable supply of energy stands high on the list of the public's concerns. The Group is committed to manufacturing city gas in accordance with these expectations.

Stable Production of City Gas and Strict Quality Control

Stable production of city gas

Our four city gas production terminals provide each other with mutual backup so that stable supplies of city gas can continue to be delivered to customers even in the event of problems such as a power outage. We also have in place highly reliable power receiving systems with core facility redundancy to ensure supply continuity.

The facilities at each of these terminals incorporate highly reliable technologies. Work is also being performed steadily to upgrade aging facilities, improve earthquake resistance, and enhance safety in order to further reinforce production stability.

Observance of statutory requirements regarding control of calorific value, combustibility, etc.
To ensure delivery of high-quality city gas to customers, characteristics including calorific value and combustibility are tested once per day, as required by law, in the course of everyday operations. We also independently conduct routine monitoring to further raise quality levels, and we ensure that our facilities are properly maintained and managed though periodic maintenance and daily inspections.

Strategic development of production facilities
We are strategically developing our production facilities from a long-term perspective that emphasizes economic performance and comprehensively takes into consideration all relevant factors, such as the projected future demand for city gas. In order to popularize and expand the use of natural gas as called for in our Challenge 2020 Vision, we brought the Hitachi LNG Terminal into commercial operation in March 2016 to meet growth in demand in and around the northern Kanto region.
The Hitachi LNG Terminal’s facilities include a large jetty capable of receiving large LNG tankers and a 230,000 kl aboveground LNG tank that is the largest of its kind in the world. Preparations for construction of a second tank in fiscal 2020 are now underway.

Maintenance of skills
The Group actively practices knowledge management contributing to further improvements in performance and abilities by sharing and utilizing the precious knowledge (including skills and expertise) cultivated in the course of many years of terminal operations, and by strengthening individual employees' own knowledge. We also provide organized, effective training in order to smooth the transfer of skills to future cohorts of engineers.
