Use of Renewable Energy

NHK Spring Group is moving forward with adoption of solar power generating equipment as part of our renewable energy facilities.

Adoption of solar power generating equipment

We installed solar power generators at our DDS Komagane Plant in fiscal 2008, our Yokohama Office in fiscal 2009, our Gunma Plant in fiscal 2011, and our Miyada Plant in fiscal 2018. In fiscal 2019, electric power generation had increased to about 12 times that of fiscal 2008, when the system was adopted. At the Yokohama Office, the system supplied an amount of electric power sufficient to run the OA equipment at company headquarters.

Domestic Group companies with solar power generating equipment installed also include NHK Sales, NHK Flex, Tokuhatsu Kogyo and Topura.

In the future, we will systematically utilize solar power generation as we move forward with reductions in energy consumption and CO2 emissions volumes.
