Hitachi have announced that it will transition its domestic power grids business to a new structure with Hitachi Energy to provide strong support for the early realisation of a carbon-neutral society and the enhancement of resilient electricity network in Japan.

Hitachi will make the most of its expertise in the domestic market, as well as leading technologies and solutions based on Hitachi Energy's knowledge and experience in global market, to contribute to Japan's Green Transformation (GX) by providing new values, such as improving the asset life cycle with the maintenance and services of existing electricity network, and supporting flexibility, stability and security of the power grids.

*The businesses and solutions covered by this transition are mainly gas insulated switchgear (GIS), transformers and High Voltage Direct Current (HVDC) businesses for utility companies and their maintenance businesses, excluding grid protection and control businesses.


1. New values to contribute to the customers and market for early realisation of a carbon-neutral society

Through the integration of the domestic power grids business and Hitachi Energy, Hitachi will provide customer with new values to realise a carbon-neutral society by leveraging Hitachi Energy's world-class technologies with Hitachi's digital technology including Lumada and the extensive experience from our domestic track record.

a. World-recognised value in power grids equipment such as high-voltage products including GIS portfolio and transformers, all supporting low environmental impact, optimisation of maintenance cycles and digitalisation.

b. The value that directly contributes to minimising power supply shortages and accelerating GX through solutions used in global markets, such as HVDC technology and EconiQ (product, service and solution package that helps achieve carbon neutrality).

2. Maximise values by co-creating with customers

a. Continue to provide high-quality services including front-end engineering, quality control, and maintenance backed by years of experience in Japan together with new digital solutions. Contributing to the enhancement of the value of investment in the power grids in Japan, aiming to maintain and improve services for existing facilities and equipment in the Japanese market along with supporting the realisation of customer's technology succession.

b. Aiming to realise the globalisation of our business platform having aligned with customers in Japan and providing them with the value created in the global market.

c. The target periods for transition to a new structure of each business together with Hitachi Energy are as follows: HVDC business, which has world's leading technologies and market shares and a proven track record in Japan since the establishment of a joint venture for Japan's HVDC business in 2015, will be from latter half of Fiscal Year (FY) 2023; the service business, which is another core business, will be from FY2024; and the equipment business including GIS and transformers will be by end of FY2024.

d. Products such as GIS and transformers will transition to those produced at Hitachi Energy's manufacturing sites, and the manufacturing base in Hitachi City, Ibaraki Prefecture will become an important base function providing advanced engineering and services from FY2025.

e. We will also provide strong support for strengthening the power grids and support collaboration efforts for the development of a nation-wide next-generation electricity network, which is being considered with a perspective on future energy sources and demand as a result of changes in social structures, such as the expansion of non-fossil based generation sources and the progress of electrification, by utilising Lumada and other digital technologies, as well as experience, know-how, technology and human resources on a global basis.
