ADW's First Grid-Scale Battery Storage Facility 'ADW Mie Matsusaka Battery Storage' Enters Frequency Regulation Market

AD Works Group Corporation (headquartered in Chiyoda-ku, Tokyo; President and CEO Hideo Tanaka; hereinafter "ADWG"), through its subsidiary AD Works Co., Ltd. (headquartered in Chiyoda-ku, Tokyo; President Shunya Suzuki; hereinafter "ADW"), which promotes income-generating real estate business, announces that its first facility, the 'ADW Mie Matsusaka Battery Storage,' which began operations this March, has entered the balancing market (primary reserve) and commenced trading.

This marks ADW's participation in the balancing market in addition to the wholesale electricity market, representing a significant milestone toward expanding revenue opportunities and accumulating expertise in its grid-scale battery storage business.

ADW positions its grid-scale battery storage business as a new growth initiative that not only contributes to solving social challenges but also supports the achievement of the company's vision—achieving pre-tax profits of 20 billion yen by 2034. The company will continue advancing this business based on the 'Growth Strategy for Grid-Scale Battery Storage' announced today.

1. Overview of the Announcement

With the increasing deployment of renewable energy, fluctuations in power generation due to weather and time of day have become critical challenges, heightening the demand for battery storage systems. The balancing market is designed to trade adjustment capacity necessary for maintaining grid stability. Battery storage systems, capable of rapid charge and discharge control, are well-suited to provide such regulation services.

The 'ADW Mie Matsusaka Battery Storage' has now commenced trading in the balancing market (primary reserve). This enables ADW to operate not only by leveraging price differences in the wholesale electricity market but also by providing regulation services in the balancing market, thereby pursuing revenue across multiple markets.

2. Significance for ADW's Grid-Scale Battery Storage Business

ADW entered the battery storage market early in 2025, building expertise through partnerships in land acquisition, development, grid interconnection, and trading in the wholesale electricity market, strengthening its competitiveness during the market formation phase. This latest development enables further accumulation of operational know-how.

Going forward, ADW will continue advancing the commissioning of additional battery storage facilities currently under development (five sites), positioning this business as a growth driver capable of contributing to profits in the medium to long term.
