1. Long-term outlook for renewable energy (power generation capacity)

Environmental Performance Data

• ※Includes 50% of the hydroelectric power plants of the Kurobe River Power Company (50% owned by the Company)

2. Denka's hydroelectric power

There are 17 hydroelectric power plants in the vicinity of the Omi Plant, including the power plant of Kurobegawa Electric Power Company, which is a joint investment with Hokuriku Electric Power Company. The maximum output of these power plants is approximately 140,000 kW, making it one of the largest of all private manufacturing facilities in Japan. All of these power plants are "inflow type" hydroelectric power plants, which guide river water to the turbine runner and return it to the river after power generation, making it a method of power generation that places less burden on the natural environment. Hydroelectric power generation not only does not emit greenhouse gases, but is also one of the excellent renewable energy sources with high energy efficiency, and can generate electricity sustainably while coexisting with nature. We will effectively utilize this resource to contribute to the realization of a sustainable society.

3. Efforts for Energy Conservation

In achieving carbon neutrality, streamlining energy use is one effective means. To date, we have promoted the switching of fuels at our thermal power plants, the introduction of high-efficiency gas turbine generators, and waste heat power generation at our cement plants, and have made efforts to use energy efficiently. More recently, in 2020, the opertaion of a high-efficiency gas turbine began at our Omi Plant, and in 2022, a similar gas turbine started operation at our Chiba Plant.

4. Initiatives for Solar Power Generation

Since 2013, we have been installing solar power generation systems at our Shibukawa Plant and Isesaki Plant located in the Gunma Prefecture.
Currently, we are considering new candidate sites including our group companies and domestic plants. To achieve our non-financail KPI of our management plan "Mission 2030" of 150 MW maximum renewable energy output as early as possible and further increase this figure, we have commenced operation of solar power generation systems at our overseas sites (Vietnam). Furthermore, we plan to install solar power generation systems at our Chiba Plant and overseas sites (Singapore) by fiscal 2025.
