Nishitetsu and Shizen Energy Establish Joint Venture to Expand Renewable Energy Generation Business
~Combining renewable energy power plant development and energy management to contribute to the decarbonization of companies and municipalities in the Kyushu area~

2022.04.20[Press Release]

Nishi – Nippon Railroad Co., Ltd. (Nishitetsu) and Shizen Energy Inc. (Shizen Energy) established a joint venture company, Nishitetsu Shizen Energy GK (Nishitestu Shizen Energy) on April 15, 2022.

 As countries around the world are currently moving toward the goal of eliminating greenhouse gas emissions by 2050, the same trend is accelerating in Japan.

 Kyushu is a favorable environment for the introduction of solar power generation and for the development and construction of solar power plants because of its abundance of land, water, wind, heat, biological resources, and other suitable sites for renewable energy development, as well as its favorable sunlight conditions. The number of solar power plants in the Kyushu area is increasing every year, with a 34% increase at the end of 2021 compared to the end of 2019.

 This collaboration between Nishitetsu, which has been operating its main businesses in Kyushu and Fukuoka for more than 110 years, and Shizen Energy, which has been developing and supporting renewable energy projects in Japan and overseas for more than a decade, will speed up the process of decarbonization and regional resilience in the Kyushu area.         

In carrying out the project, Nishitetsu will provide information through its regional network, install the power generation system in its own group facilities, and utilize idle land, while Shizen Energy will provide its expertise in project development, construction, maintenance, and other services.

The project aims to complete construction of 30 MW of renewable energy power generation facilities by FY2025 (6.5 MW by the end of FY2023).

 Firstly, by FY2022, the Nishitetsu Group plans to install solar power generation facilities at its Hakata International Exhibition Hall & Conference Center, Narita Logistics Center, and Kyushu Metal Industry No.2 Dust Warehouse to supply renewable energy electricity.

<Nishitetsu comment>
The Nishitetsu Group recognizes that preservation of the global environment is an important issue in order to contribute to the realization of a sustainable society and to be a company that is trusted by society and continues to grow over the long term. Through this collaboration with Shizen Energy, we will speed up the development of renewable energy sources and energy management initiatives, as well as supply green power to the Nishitetsu Group and beyond. In the future, we will also supply power to EV buses and other vehicles owned by our own company, as well as to other transportation and logistics providers and EVs owned by local municipalities, in order to accelerate decarbonization and practice sustainable management.

<Shizen Energy comment>
We have been involved in more than 1 GW (1 GW = equivalent to approximately one nuclear power plant) of renewable energy projects in Japan and overseas based on our company purpose of “We take action for the blue planet.” In the collaboration with Nishitetsu, we will combine the strengths of both companies and consider not only the creation of renewable energy sources, but the use of digital technology for private consumption at factories and commercial facilities, and the effective use of renewable energy in mobility, such as EV buses. Currently, the energy conversion and transportation sectors account for more than 50% of CO2 emissions in Japan. Through this collaboration, we hope to synergistically accelerate the structural shift toward decarbonization in both sectors, thereby contributing to the decarbonization of Japan.
