Environmental Harmony Measures by Power Stations

In constructing power stations, the measures such as the preparation and improvement of green tracts in the premises of the power stations have so far been taken to actively promote the reconciliation between the environmental preservation and the local community.

In addition, we are making efforts to reduce the environmental impact from waste water, noise, etc. during construction work of power facilities while seeking to form facilities taking natural environment and landscaping into account.

Security of Water Flow to Maintain Rivers

In the downstream of a hydroelectric station dam, in order to mitigate the impact of water reduction caused by power generation, harmonization with river environment is pursued by securing the specific volume of water if certain conditions apply, in consultation with the authorities concerned.

Formation of Green Tracts in Harmony with Surrounding Environment

Our power stations work on harmony with the vicinity by conducting greening works in their premises.

Measures to Reduce Environmental Impact during Construction Work

We are taking various measures to prevent water pollution. As an example, waste water from construction work is adjusted for its turbidity and pH before discharge by placing a murky water treatment facility and a temporary depositing reservoir. Furthermore, we adopt a low-noise and low-vibration construction method for construction work taking the surrounding environment into account as well as seek to control the generation of dust and particles by laying blown sand-prevention sheets on earth-and-sand collection site and cleaning and sprinkling water on the roads in the premises.

In addition to these measures, the efforts to prevent proliferation of water pollution are being made during dredging work for harbor construction and other works through installation of pollution control frames and other means.

Higashi-Niigata Thermal Power Station Receives the Prize of the Minister of Economy, Trade and Industry for Excellence in Greening by an Industrial Plant, etc.

Higashi-Niigata thermal power station received the "Prize of the Minister of Economy, Trade and Industry for Excellence in Greening by an Industrial Plant, etc." in October 2004. It was recognized for its continued efforts to promote greening with a view to harmonizing with the natural environment of the local community since the commencement of construction as well as for wide openness of the facilities within its premises to the local residents in the form of Hamanasu Park and the athletic field as the power station that harmoniously coexists with the local community.

Environment-Friendly Measures for Transmission, Transformation, and Distribution Facilities

Power Transmission and Transformation Facilities

In constructing transmission lines, we seek to give due consideration to the landscape of the national parks around the transmission lines through such means as low gloss coating on the steel towers as well as low reflection coating on transmission lines as required.

In addition, we are taking the measures to form those facilities in harmony with the local communities and to reduce environmental impact. Such measures include the greening of the premises of substations and the placement of grit chambers for reducing environmental impact during construction work as well as the use of low noise transformers.

Power Distribution Facilities

Power distribution lines are installed underground with a view to creating desirable towns promoted by the central government that takes into account the urban landscape and comfortable life environments.

In addition, the poles in harmony with environment such as color poles in harmony with natural environment and small diameter poles in harmony with urban space are used while taking advantage of economical efficiency and easiness of maintenance of the power distribution lines using support materials.
