Electrical energy, being a very convenient form of energy, has become fully pervasive in the modern world. As the distribution system is the link through which an individual consumer draws electrical energy from the power system. Proper design of the distribution system becomes very important for reliability and maintenance of continuity of electric supply. Transmission and distribution systems provide a lifeline to rural and urban areas alike, bringing clear socioeconomic benefits to communities.

The transmission and distribution space (T&D), is an important cluster of industries that include the production of machinery, electric lines and transformers as well as line management systems (such as "smart-grid" technology) that improve efficiency. Our Company specialists have extensive knowledge and experience in designing power transmission lines and electrical substations, as well as construction management during the installation of overhead transmission lines and underground power cables.

Our teams of specialist project managers, designers and engineers provide vast knowledge and comprehensive expertise to support clients in planning and implementing transmission and distribution networks that will perform efficiently over the long term. Nippon Koei provides services in system analysis, feasibility studies, planning, design, tender document writing, contract negotiations, supervision and commissioning for electricity transmission and distribution projects. Power system analyses services include, but are not limited to, load flow, short circuit and transient overvoltage studies and grounding system design.
