Renewable Energy

Initiatives

We have been making a concerted effort to meet the social demand of “realizing a low-carbon society” by striving to accelerate the development of new power sources as well as effectively utilize existing power sources.
In the development of new power sources, to achieve the target of “development of 2,000 MW or more around 2030,” we decided to go forward with five development projects in FY2019 including the Uchigatani Hydroelectric Power Station, the Akita Port Offshore Wind Power Station and Noshiro Port Offshore Wind Power Station, and the Aichi Gamagori Biomass Power Station. We are aiming to achieve these targets by obtaining the understanding of the local community, bearing in mind consideration for the environment, seeking out sites both within and outside of the area by leveraging the advanced technological skills held by the Group, and accelerating various initiatives including joint development with other companies.
As for existing power sources, amid intensifying natural disasters in recent years such as Typhoon 19 which hit Japan in 2019, we will need to implement ongoing initiatives to increase power generation output such as minimizing power loss through surplus power at overflow* and improving the rate of facility utilization, upon appropriately maintaining and managing the facilities under this harsh environment, and achieve stable power generation at an affordable price by maximizing our facility capacity.
We will continue to proactively promote the development of new renewable energy power sources while maximizing existing power sources to “contribute to the realization of a low-carbon society.”

* Power not generated due to maintenance work, breakdown, etc.

Initiatives to Achieve Our Goals

Increasing the Energy Self-Sufficiency Rate and Realizing a Low-Carbon Society

The Company has set “development of 2,000 MW or more around 2030” as its target and has been steadily promoting the development of renewable energy in order to improve the energy self-sufficiency rate and realize a low-carbon society. This will be an extremely challenging target that aims to double the capacity of power generation capabilities. To achieve this target, we will aggressively carry forward the development of hydroelectric power, biomass, land-based wind power, and solar power generation capabilities in the medium term and offshore wind power and geothermal in the long term, and aim to increase the energy self-sufficiency rate and to realize a low-carbon society.

Installed Capacity Double the power generation capacity through the development of 2,000 MW or more

Main Recent Development Sites

To achieve “the development of 2,000 MW or more around 2030,” we decided to go forward with 5 development projects in FY2019 including the Uchigatani Hydroelectric Power Station, the Akita Port Offshore Wind Power Station and Noshiro Port Offshore Wind Power Station, and the Aichi Gamagori Biomass Power Station. Additionally, in May 2020, the Yokkaichi Biomass Power Station, which had been under construction, began commercial operations. We will steadily continue our development projects as the Seinaiji Hydroelectric Power Station and the Yonago Biomass Power Station, which are currently under construction at the new development sites while accelerating the search for new sites and aim to achieve our targets.
