First in Japan: GO Inc. Enters Electricity Supply-Demand Adjustment Market by Utilizing EV Charging at Multiple Locations, Contributing to Domestic Power Grid Stabilization with AI Technology Cultivated in Mobility Sector

GO Inc. (Headquarters: Minato-ku, Tokyo; President: Hiroshi Nakajima) will enter the electricity supply-demand adjustment market*1 from April 2026 and commence its electricity aggregation business. By utilizing AI technology cultivated by the company in the mobility sector, it has achieved Japan's first*2 provision of adjustment capability created by adjusting the charging volume for EV vehicles located at multiple sites. The company plans to expand this initiative nationwide, contributing to both decarbonization and stable electricity supply.

*1 A market that procures "adjustment capability" necessary for frequency control and balancing electricity supply and demand in the power grid.
*2 According to research by GO Inc. and MC Retail Energy.

## Aggregating Distributed Resources at Multiple Locations into a Single Adjustment Capability for Market Provision

In the Japanese electricity market, the importance of adjustment capability is increasing to maintain the supply-demand balance as the introduction of renewable energy progresses. As a resource aggregator, GO Inc. will provide adjustment capability to the supply-demand adjustment market through its aggregation coordinator, MC Retail Energy Inc. (Location: Chiyoda-ku, Tokyo; President: Takayuki Araki). By controlling the charging volume of EV vehicles connected to over 230 chargers*3 at times when there is a potential for instability in electricity supply, these distributed resources will be aggregated into a single adjustment capability. The target EV chargers are those installed by GO Inc. for providing EV charging services. The provided adjustment capability will be used by transmission and distribution operators to ensure stable electricity supply for the domestic power grid.

*3 As of commencement. Planned for sequential expansion.

## System Development Utilizing AI Technology Cultivated in Mobility Sector for the Power Sector

Leveraging its technological foundation in the GX (Green Transformation) and mobility domains, GO Inc. has achieved Japan's first provision of adjustment capability by adjusting the charging volume for EV vehicles located at multiple sites. In its GX business, the company has developed and built a charging management system that optimizes charging for EV vehicle operations.
