Daiwa House Group’s Environment and Energy Business

The Daiwa House Group’s Founder, Nobuo Ishibashi, predicted that the 21st century would be an era of wind, solar, and hydro power. Following his vision, the Group entered the wind power generation business in 2007. Since then, while leveraging our extensive construction experience, we have been making optimal proposals to customers for installation of solar, wind, and hydroelectric equipment based on the condition of their existing buildings and the surrounding land. We also sell renewable electricity, developing and operating our own green power facilities, while engaging in the retail electricity business. Leveraging decades of expertise and our nationwide land database, we are committed to creating a sustainable future for the planet. By treating all of society as our customer, we will keep building a decarbonized world.

Utilization of the sun (Solar power generation systems)
530 locations 652MW*

Utilizing various unused land parcels across Japan, the Group has been developing its DREAM Solar project, a one-stop solar power service that handles everything from installation to operation and management. In addition to designing and constructing large-scale solar power facilities (solar farms), we are currently strengthening our corporate power purchase agreement (PPA) initiatives. This represents a new business model that can thrive after the planned end of Japan’s feed-in tariff (FIT) system. Utilizing our nationwide land database, we are actively pursuing off-site PPA projects based on suitable site searches, as well as on-site PPA projects by utilizing rooftops and other structures.

New business scheme for expanding renewable energy: The PPA model

We offer power purchase agreements (PPAs) in the form of a contract under which we install solar power equipment on rooftops or unused land that we rent from the customer. The electricity generated by the equipment is then sold to the customer for use in their facilities. Since the customer does not own the equipment, it is also known as a third-party model. For customers, this allows cost-effective adoption of renewable electricity, as there are no initial installation costs or maintenance expenses.

Off-site PPAs

A service model where renewable electricity is supplied to the customer’s operation site using power generation equipment installed in a separate location.

On-site PPAs

A service model where renewable electricity is generated at the customer’s operation site, and supplied without utilizing the power grid.

Utilization of wind (Wind power generation systems)
18 locations 26MW*

In the fourth quarter of the year 2000, the Group installed three large wind turbines, with a total generating capacity of one megawatt, at Royal Hotel Noto in Ishikawa Prefecture, and at Royal Hotel Okinawa Zanpamisaki in Okinawa Prefecture. We then fully entered the wind power generation business in February 2007, when our wind turbines began generating electricity on the Sadamisaki Peninsula in Ehime Prefecture, with a capacity of nine megawatts. Since then, we have been installing and managing a variety of wind turbine projects, both large and small.

Suganuma First Hydroelectric Power Plant

In November 2017, we developed and began operating a hydroelectric power plant in Hida City, Gifu Prefecture. The electricity generated there is used in the Funabashi Grand Oasis development in Chiba Prefecture, which was also built by the Group. This community development has achieved a renewable energy usage rate of 100%, as a result of the Group’s coordinated efforts.
