Environmental Initiatives

Practice of Environmental Management

The Chubu Electric Power Group aims for sustainable growth as a total energy service corporate group that is one step ahead by providing safe, affordable, and stable energy of high quality with consideration for the environment as well as a new form of community through the establishment of community support infrastructures.
To achieve these goals, the Chubu Electric Power Group will practice appropriate environmental management, and each and every one of our employees shall exercise discipline and act in an environmentally conscious manner. We will contribute to the sustainable development of society through implementation of initiatives in all aspects of energy value chain aiming to achieve a carbon-free and recycling-oriented society that is in harmony with nature.


We are committed to the conservation of biodiversity through consideration of ecosystems in our business activities and efforts in technological development and research.

【Goal】Ensure ongoing efforts to conserve ecosystems

Environmental assessment

When executing a project, we investigate, estimate and assess its impact on the environment in accordance with relevant laws and regulations and implement appropriate environmental conservation measures while listening to opinions of local community members.

Protection of rare plant species and raptorial birds

During construction projects involving power transmission lines and substations, we implement strategies to prevent the loss of rare plant species. This includes relocating plants and reducing the construction footprint. Furthermore, we modify construction procedures and helicopter flight paths to protect raptorial birds. Upon project completion, our efforts extend to rejuvenating the natural environment in the vicinity, with the goal of minimizing the impact on ecosystems.

Development of conservation technology for endangered species

We have taken measures to protect endangered species such as the Aconitum kiyomiense, a flowering plant found on our company-owned lands and in the vicinity of power facilities. Our efforts include gaining insights into their physiology and ecology, developing propagation techniques, and implementing active conservation measures.

Control of invasive species

We have established a chemical spraying program to gradually reduce and eradicate the specific invasive species known as burr cucumber. Additionally, we participate annually in the removal of invasive Phyllostachys edulis bamboo at green spaces owned by the city of Nagoya.

Water resources

We are committed to the sustainable management and efficient utilization of water resources.

【Goal】Minimize water usage in our offices

Water conservation in offices and increased employee awareness of water conservation We work to raise water-saving awareness of employees and reduce water use by proactively introducing water-saving sanitary equipment as a measure to save water and by calculating and visualizing the amount of water used by each employee.

【Goal】Minimize environmental impact through responsible water resource utilization

Forest preservation activities including the protection of watershed protection forest We are engaged in activities to preserve Uchigatani Forest and other forests.

Appropriate use of water through dam operations In conducting hydroelectric power generation, we implement measures against turbid water and conduct dam discharge to keep the required river flow volume, and by doing so,work to ensure the cleanness of river water, maintain river channels and ultimately conserve riverine environments.

Recycling-oriented society

We promote resource conservation, waste reduction, and the reuse/recycling of resources to minimize disposal.

【Goal】Achieve a recycling rate of over 95% for industrial and other waste

Recycling rate of industrial and other waste: 97.3% (FY2022) We have been working to recycle more industrial waste, recycling 95% or more of the waste we generate.

Disposal of PCB waste (hazardous waste): 1,601 tons (FY2022) We are systematically and responsibly progressing with proper disposal.

Response to the Act on Promotion of Resource Circulation for Plastics Our corporate uniforms are made of synthetic fibers, and upon disposal, they are classified as "waste plastics." After use, the uniforms are transformed into refuse derived paper and plastics densified (RPF) fuel at Terrarem Group Co., Ltd., a company in which we hold a capital stake. This RPF fuel is sold as an alternative to coal and is utilized in biomass power plants and other applications.

Reuse of clearance metal We are actively pursuing the reuse of clearance metals generated during the decommissioning of the Hamaoka Nuclear Power Station Units 1 and 2. Currently, in collaboration with local businesses, we are processing these metals into metal covers for gutters.

* "Clearance metals" refer to metals from radioactive waste generated during the decommissioning or operation of nuclear power plants, which have low levels of radioactive substances and pose minimal health risks to humans. These metals have been approved and confirmed by the government to be reused or disposed of as regular waste.
