Our Business

Network Business

We will continue working to create more resilient facilities, such as by replacing gas pipelines with more earthquake-resistant materials such as polyethylene pipes and subdividing the number of supply blocks.

Utilizing the communication function of smart meters

We are working to enhance safety and productivity through DX. In FY2026.3, we have utilized the communication functions of smart meters to ensure rapid security and streamline work.

Emergency gas shutoff and restoration work and monthly meter reading can be performed remotely

Automatic generation of pipe construction drawings using 3D imaging technology

We have also begun automatically creating pipeline construction drawings using 3D photos to reduce the time necessary to create drawings and improve work efficiency.

Initiatives to Maintain and Expand Gas Retail Business

We aim to maintain and expand gas sales and supply volume by expanding our residential space services, fuel conversion activities, and strengthening sales of energy services.

Initiatives for residential customers

In addition to conventional gas appliances, we aim to realize smart and comfortable lifestyles by connecting solar power generation and electric vehicles with IoT and managing energy with the best mix of gas and electricity.
In FY2026.3, we will expand our residential space services by strengthening nationwide sales of Sumai Roof, a solar power generation service that can be started with zero installation cost, and adding new menu items to Sumikata Services.

Initiatives for commercial and industrial customers

We will further enhance our D-Lineup as a solution service that solves various problems for our customers from the three perspectives of carbon neutral, 3R*, and DX. Services include reducing and recycling food waste and wastewater with the aim of sustainable resource circulation, and supporting business activities by using data and digital technology to address issues such as labor shortages and technology transfer.

Initiatives for low-carbon natural gas-fired power generation

To achieve low carbonization and a stable power supply, natural gas-fired power generation, which allows for easy output adjustment, is essential. The Daigas Group started full-scale construction of the Himeji Natural Gas Power Plant in August 2022. Unit 1 is scheduled to begin operation in January 2026, and Unit 2 in May of the same year, with a power generation capacity of approximately 1.2 GW. This will expand our domestic thermal power generation capacity from 2.0 GW to 3.2 GW.
In addition, in March 2025, we decided to jointly construct a natural gas power plant (Himeji Natural Gas Power Plant Unit 3), which we won in a long-term decarbonized power source auction, with several other companies. We will introduce a highly efficient gas turbine combined cycle power generation facility with a capacity of approximately 0.6 GW, and aim to start operation in FY2031.3.

Initiatives in LNG and electricity trading markets

The Daigas Group leverages its strengths in owning a value chain from LNG procurement to sales to optimize the operation of its own facilities as well as market transactions, thereby reducing procurement costs while maintaining a stable supply of gas and power and maximizing trading profits.

Initiatives in LNG and electricity trading markets

As one example of optimization, when LNG is expensive and electricity is cheap, the Group will suppress power generation, buy cheap electricity from the market, and sell the surplus LNG. By purchasing surplus electricity on the market and providing LNG where there is a shortage, the Group contributes to adjusting the electricity supply and demand, and in return earns trading profits.

Initiatives to promote the spread of renewable energy

The Daigas Group has been developing a variety of renewable energy sources, including solar, biomass, and wind power. All eight biomass power plants that have been developed and constructed so far are already in operation.

In addition, as storage batteries can level out the load on the grid due to the large-scale spread of renewable energy, their importance will increase in the future. The Group is promoting the sale of storage batteries and the installation of storage stations for residential, commercial, and industrial use, in addition to grid-use and renewable energy-connected types. By bundling these together into a virtual power plant, we are aiming to grow into one of the top storage battery operators in Japan.
