Substations are indispensable to supplying high-voltage power generated by power plants for consumers to use. These facilities are not only necessary to power infrastructure but also require a high level of reliability and safety. The Hitachi Plant Construction Substation Business mainly installs substation equipment, handles the civil and construction work, and designs, constructs and delivers steel towers and other auxiliary equipment.
Through this wide range of work, Hitachi Plant Construction contributes to the construction of facilities that can supply safer, more reliable power by considering the most efficient construction methods capitalizing on extensive experience and specialized knowledge while using its unique strengths in operational support systems taking advantage of IT.
The Hitachi Plant Construction Substation Business has earned high praise from its customers and has expanded its business domains not only in Japan but also overseas.
Our substation business in Japan focuses on power companies and private enterprises (industrial facilities) in an effort to contribute to the construction of ultra-high voltage Gas-Insulated Switchgear (GIS) substations, frequency converter stations, and other facilities from planning and design through production and installation, as well as the preventative maintenance from modifications through renewal work.
We also work in the field of effective high-voltage direct current distribution to enhance the power resilience of Japan and strengthen the power links between regions.
