Stable Production of City GasOur four city gas production terminals mutually back up each other so that we can continue to deliver a stable supply of gas to customers, even in the event of power outages or other problems. Highly reliable power receiving systems with core facility redundancy are also in place to ensure steady production of city gas. Each terminal is equipped with highly reliable facilities, and we are enhancing our safety measures by steadily upgrading aging facilities and strengthening earthquake resistance for even greater stability in production.

Economic Advantages of Production
City gas using LNG as feedstock is produced by pouring seawater to vaporize LNG stored in a tank at minus 162°C and adjusting the calorific value. The process does not require large-scale manufacturing facilities, thereby keeping production costs down.
Compliance with Statutory RequirementsTo ensure delivery of high-quality city gas to customers, we daily inspect calorific value, combustibility and other properties, as stipulated by law, and strive to improve quality further by conducting independent monitoring regularly while also maintaining and managing facilities though periodic maintenance and daily inspections.
Strategic Development of Production FacilitiesWe are strategically developing our production facilities from a long-term perspective that emphasizes economic performance, applying a comprehensive approach as we consider issues such as projected future demand for city gas. To encourage the broader adoption of natural gas, a goal under our Challenge 2020 Vision, we began commercial operations at the Hitachi LNG Terminal in March 2016 to meet expanding demand in the northern Kanto region. The Hitachi LNG Terminal has a big jetty capable of receiving large LNG carriers and a 230,000 kl aboveground LNG tank, the largest of its kind in the world. In April 2018, we began constructing a second tank, scheduled to start operating in fiscal 2020, to keep pace with the growing demand for natural gas.
Initiatives for Handing Down SkillsThe Tokyo Gas Group actively manages knowledge by sharing and utilizing the valuable learnings, technology and skills it has acquired over many years of operating terminals in order to deepen each employee’s understanding and thereby enhance their performance and abilities. We are also systematically developing human resources to ensure that skills are smoothly transferred to each succeeding generation.
