Special Feature: The Daigas Group addresses social issues with its human resources and technical expertise

Contributing to the Sustainable Development Goals

Since 1905, the Daigas Group has been supplying gas and providing products and services tailored to the needs of individual customers and society at large under the motto “service first.” Our Group emphasizes customer convenience and undertakes the necessary research and development into innovative technologies that, put to practical use, help our customers live in a more energy-efficient manner. In 2006, the Daigas Group adopted its CSR Charter, a document intended to spell out how we will meet the expectations of stakeholders and fulfill our corporate social responsibility. Our CSR Charter serves as an action guideline for both our executive management and our rank-and-file employees; using this document, the Group implements CSR initiatives intended to contribute to the emergence of a sustainable society. Through its business operations, the Daigas Group remains focused on addressing social issues.

Our Group is engaged primarily in the energy business. In recent years, we have taken on the extremely important mission of reducing our emissions of greenhouse gases (GHG), which have been linked to the climate change issue. Specifically, we aim to reduce our total CO2 emissions by approximately 70 million tonnes by FY2031. In this endeavor, our Group engages in a variety of business initiatives that include expanding the use of renewable energy, promoting the adoption of advanced energy equipment, and launching LNG businesses and other businesses inside and outside Japan. Moreover, considering the increasing frequency of recent natural disasters, the Group is working to improve its resilience by adopting disaster-response measures and improving its ability to ensure the rapid recovery of the infrastructure on which the public depends.

These initiatives are creating value through our efforts at innovation utilizing the many proprietary technologies that our Group has developed over the years. Everyone at our Group is collaborating on the development of new services that not only support the Group but also address the problems that challenge our customers.

We believe these activities contribute to several of the Sustainable Development Goals (SDGs) proposed by the UN. These include Goal 13, which calls for urgent action to combat climate change and its impacts; Goal 12, which calls for responsible consumption and production; Goal 7, which calls for assured access to affordable, reliable, sustainable, and modern energy for all; and Goal 9, which is intended to foster innovation, inclusive and sustainable industry, and the construction of resilient infrastructure. We believe that promoting these initiatives will trigger the creation of opportunities realizing sustainable town planning, increased employment, and creation of spaces conducive to active engagement of diverse personnel. In addition to the above, we believe we can contribute to the achievement of several other goals and targets that comprise the SDGs. (For more details, please refer to the section titled “CSR Integrated into Management Strategy” on our corporate website.)

The Daigas Group will address climate change as a comprehensive energy service provider.
The Group is committed to contributing to development of industries and communities through the provision of sustainable energy.

Special Feature 1 : Reducing greenhouse gas emissions through efficient use of natural gas and expansion of renewable energy

Accelerating the adoption of sustainable energy and services

United Nations Framework Convention on Climate Change

Devising ways to reduce the greenhouse gas (GHG ) emissions associated with climate change has long remained a formidable challenge. Clearly, energy companies are required to do more. Such effort includes promoting the adoption of natural gas, which is associated with low CO2 emissions, and increasing the ratio of renewable energy sources—such as wind and solar power—in the energy mix.

As a gas and electricity provider, we intend to further accelerate the development and acquisition of renewable energy sources as outlined in our FY2019 management plan, in which we have adopted the target of renewable energy generation capacity 1 million kW by FY2031 in the Japan and overseas markets.

Moreover, we remain committed to further expanding our natural gas business, which is noted for its low CO2 emissions, and developing a variety of power sources while contributing to the provision of sustainable energy and services.

Realizing the potential of proprietary simulation technologies developed by the energy business operator

Weather conditions have a significant impact on the energy industry, as daily temperatures drive demand while changes in solar radiation affect the amount of solar power generated. The dramatic impact of weather has compelled us to develop weather and wind simulation technology that assists us in forecasting changes in wind and solar radiation. The weather data we compile from this technology is also used effectively by various businesses.

This weather and wind condition simulation technology was used in the design of the 26,000 kW Inami Wind Power Plant in Wakayama Prefecture that a Daigas Group company, Gas and Power Co., Ltd., put into service in June 2018. The company used this technology to select the location of the windmill and to forecast the amount of power this facility would likely generate over the next 20 years.

Contributing to the provision of services and the development and operation of a wide range of power sources

Our Group takes advantage of its years of experience and outstanding expertise to develop a diverse array of power sources and create sustainable infrastructure that contributes to the emergence of a low-carbon society. This effort includes the launching of LNG businesses outside the Kansai area and promoting biomass power generation by establishing procurement and sales companies for domestic woody biomass fuels.

Currently, we have approx. 210,000 kW of renewable energy sources including wind, solar, and biomass power plants in Japan, which contribute to reducing CO2 emission.

In an effort to further spread renewable energy, in FY2019 we decided to construct two of Japan’s largest biomass power plants, each with a capacity of approx. 75,000 kW, in Sodegaura, Chiba Prefecture, and Himeji, Hyogo Prefecture.

The weather analysis is indispensable for operation of energy businesses. Since undertaking analysis of the air flow within and from fan heaters some 30 years ago, the Energy Technology Laboratories have pioneered various applications of fluid simulation technology, including the combustion process in industrial furnaces, diffusion of exhaust gases, and the flow inside the Ene-Farm. The fluid simulation technology we have developed here uses computers to predict the flow of gases and liquids. We came to realize that if these technologies could be adapted to forecast the wind, solar radiation, rain, and other elements of weather, they would become a new fundamental technology, so we started working on ways to put our weather simulation technology to practical use. In recent years, we have been using this technology for wind power generation projects.



In 2005, I became involved in predicting the amount of power that would be generated by the Hirokawa Myojinyama Wind Power Plant in Wakayama Prefecture, which was being planned at the time. I discovered that I could come up with reliable predictions by leveraging my knowledge and experience in predicting the air flow around objects having complex shapes. Since then, we have accumulated a significant amount of skill and data uniquely applicable to wind power generation. To date, we have used this expertise to evaluate a number of wind power projects both inside and outside Japan, including the Hallett 4 Project in South Australia. These achievements have enabled us to evaluate the business case for the Inami Wind Power Plant.

In the future, we aim to provide this service to industries requiring weather forecasting. These include the agriculture industry, which depends on temperature and weather forecasts for making harvesting decisions, and the retail and service industries, whose pricing and customer traffic are affected by the weather.
