Grom Holdings Accelerates Electric Power Storage Project Ahead of Schedule

Grom Holdings, based in Minato, Tokyo, has recently achieved a remarkable milestone in its energy sector endeavors. The company announced that the inspection and handover of its second power storage facility were completed on July 10, 2026, advancing the timeline by approximately seven weeks compared to earlier projections. This proactive step enhances their capacity to stabilize the electric power grid, which is becoming increasingly crucial due to the growing reliance on renewable energy sources.

Initial plans projected the starting date for the power storage project as September 1, 2026. However, significant progress in development and favorable circumstances led the company to adjust its schedule. The revised timeline was announced on June 11, 2026, setting a new completion date for the project as July 17, 2026. The swift completion of the inspection process has now allowed the handover to occur even earlier than anticipated.

Project Timeline Overview

The timeline of public announcements showcases Grom's strategic planning and execution for this significant project:



The successful inspection signifies that the equipment has been installed as per specifications, fulfilling acceptance criteria. Grom Holdings targets projects with established permissions and completed installations to minimize risks during the acquisition process, resulting in quicker timelines from contract to handover.

Strategic Acquisitions and Partnerships

The contracts regarding the power storage project were mainly orchestrated by Grom's consolidated subsidiary, Fukuyama Medical Equipment Co., Ltd. Furthermore, agreements have been made with aggregators, entities that balance power supply and demand, maximizing the use of energy resources.

What is a Power Storage Facility?

These facilities are designed to connect directly to the power grid, assisting with demand and supply adjustments, frequency control, and leveraging price differences in electricity operations. Given the rise of renewable energy sources, the significance of such facilities has grown, and governmental support measures are being developed to enhance this infrastructure.

The Japanese government has emphasized the need for renewable energy as a primary power source in its 7th Energy Basic Plan, reinforcing the essential role of power storage solutions in stabilizing the electric power grid.

Future Developments

Grom Holdings is not resting on its laurels; it plans to enter the demand adjustment market by the end of 2026, advancing its operational capabilities. It has made a strategic decision to create a wholly-owned subsidiary, Grom Energy Co., Ltd., which will focus on managing power storage operations, aiming to develop this venture as the second core business after its medical-related projects by August 2026.

In the words of President Masazumi Sugahara, “Our approach of acquiring projects where installations are already underway significantly shortened the timeline from agreement to handover. We are determined to continue building and operationalizing power storage facilities.”

The progress of the projects will be communicated through timely disclosures as significant developments occur.
