PowerX and NTT Anode Energy Begin Exploring Collaboration in Battery Storage Business

TOKYO, JAPAN — PowerX, Inc. (Head Office: Tamano City, Okayama Prefecture; Director, President and CEO: Masahiro Ito; Securities Code: 485A) has reached an agreement with NTT Anode Energy Corporation (Head Office: Minato City, Tokyo; President and CEO: Teruyuki Kishimoto) to begin exploring collaboration in the battery storage business. Under this agreement, the two companies will initiate discussions on concrete areas of cooperation, starting with coordination on maintenance services for battery energy storage systems (BESS), with the aim of expanding both companies’ battery storage operations.

As the adoption of renewable energy accelerates toward the realization of a decarbonized society, grid-scale battery farms are rapidly gaining importance as critical power infrastructure for stabilizing the electricity supply-demand balance. PowerX and NTT Anode Energy have built a strong cooperative relationship, with PowerX’s BESS deployed across NTT Anode Energy’s eight battery farm sites nationwide. This agreement will further strengthen their partnership, with both companies aiming to jointly deliver high-quality infrastructure development and maintenance services.

As a first step in this collaboration, the two companies will explore ways to integrate their respective expertise in the maintenance of PowerX’s BESS to achieve more optimal maintenance and operations. Specifically, the partnership will leverage NTT Anode Energy’s extensive maintenance infrastructure—its nationwide service bases and approximately 1,700 certified electrical engineers—through its “Battery Farm Development and Operation Service,” aiming to deliver faster and more reliable services going forward.

PowerX, a leader in the domestic manufacturing of grid-scale BESS, and NTT Anode Energy, one of Japan’s largest battery farm operators, will contribute to the development of high-quality battery storage infrastructure and the realization of a carbon-neutral society through this collaboration.
