Electric Power

We are actively working as a general consultant on electric power civil engineering. ​

電力

In the field of electric power that serves as a part of energy supply, electricity facilities exist in various mountains, coastal areas and urban areas, and the amount is enormous. In the electric power section, our technical specialists respond with the latest know-how based on our experiences about a wide range of operations related to electric power, such as inspection/design of new civil engineering facilities for hydroelectric power and thermal nuclear power, renewal of existing power plants, survey/design of distribution facilities, and maintenance of existing electric power facilities. 

Services

Hydroelectric Power Replacement​

上水道計画設計​

Many of the hydroelectric power plants were built before World War II, and the power-generating capacity is relatively small. As it is becoming difficult to develop large-scale dams, it is better to aim for expansion by utilizing and updating existing facilities in order to continue to generate stable electricity in the future. We update designs of relevant civil engineering facilities accompanied by updating to a water turbine with excellent power generation efficiency.

New Hydroelectric Power Site Designing

水力新規地点設計​

While the expansion of renewable energy is an important issue, the expectation for small hydroelectric power generation is increasing because it uses natural circulation of water, so fuel is unnecessary. We conduct based on comprehensive evaluation and planning from the selection of power generation planning location whether installing hydroelectric power generating is possible and how much power generation (supply) is possible.

Power Facility Designing

電力設備設計​

Electricity is created at a power plant and is delivered to each facility by power transmission, power substation and power distribution equipment. In these operations, we survey, plan and design power transmission line tower foundations, power substation structures, power substation equipment foundations and underground tunnels as distribution facilities, and also screens, gates and fishways as hydroelectric power related facilities.

Survey/Inspection Repair​

調査診断補修​

In hydroelectric power plants that have been used for a long time have aged deterioration such as neutralization in the dams/water intake facilities, local damage of machinery such as a gate part, and deformation by the hollowing-out of water tunnel lining back surface. We inspect these variations, determine soundness and design countermeasures.

Earthquake Resistance Analytic Diagnosis

耐震解析診断​

While working on seismic safety evaluations in preparation for powerful earthquakes, The Ministry of Economy, Trade and Industry formulated the “Seismic Safety Evaluation Manual for Hydroelectric Power Facility” and The Ministry of Land, Infrastructure and Transport formulated “Guidelines for Seismic Safety Evaluation of Dams” as a risk verification of public disaster. Based on this manual’s guidelines, we check whether safety verification of hydrographic structures toward level 2 earthquakes and the correct seismic safety procedures to use are assured.
