In recent years, expectations are turning more toward natural gas. Under these circumstances, Osaka Gas has been working to diversify the sources from which natural gas is procured. The Company has also been participating in gas field development. By doing so, we are striving to establish a system to procure LNG at reasonable prices and in a stable manner.

electricity transmission(via the grid own by the power company/supply)

To ensure stable city gas supply, Osaka Gas has been renovating processing facilities and building gas pipeline networks in accordance with meticulous plans. We have established a solid system in order that we can exercise safety and security measures 24 hours a day, 365 days a year in response to any emergency.

Electricity generated from power sources owned by the Daigas Group is supplied to customers using the grid operated by Kansai Electric Power Co., Inc. The use of Kansai Electric Power's grid makes the power supply of the Daigas Group less vulnerable to emergency problems that may occur at power stations operated by the Group—a mechanism that would not result in the interruption of electricity supply.
