Originally established as Ishikawajima Shipyard, IHI has expanded into multiple industrial sectors over 170+ years, including energy and the environment, industrial systems, aero and space engines, and social infrastructure. 

IHI’s long history, global presence, and deep expertise combine to deliver exceptional bankability and support to its subsidiaries and sister companies. All of us work under the corporate message “Realize Your Dreams,” which captures IHI’s commitment to helping society achieve new levels of technological and social advancement.

IHI Terrasun was established as a separate subsidiary in 2014. The group was positioned to develop software and provide energy storage products and services. To further develop our advanced optimization capabilities, IHI Terrasun purchased the ESWare — an advanced, non-linear, economic algorithm-based software — from 24M.

In March 2020, HI Terrasun Solutions was incorporated as a solar and storage lifecycle services provider. Supported by the exceptional resources of our global parent organization, IHI Terrasun now delivers industry-leading energy storage expertise, robust service offerings, and technology-agnostic solutions to achieve the most ambitious energy storage goals of our clients.
