Japanese telecommunications and data center giant, NTT, has made a significant move in the energy sector by launching a new energy storage division within its subsidiary, NTT Anode Energy. This division focuses on providing utility-scale battery storage services for corporate clients, leveraging NTT’s expertise in battery energy storage systems (BESS).
Currently, NTT Anode is managing 340 MWh of BESS capacity spread across 23 sites in Japan. In recent developments, the firm has expanded its presence with new facilities in Saitama. These include the Saitama Wako storage battery (1 MW/5 MWh), Saitama Miyoshi power storage plant (2 MW/10 MWh), and the Saitama Tsurugashima power storage plant (2 MW/10 MWh), all of which are now operational.
These storage systems are actively engaged in Japan’s energy markets, participating in wholesale energy trading, grid balancing, and capacity services. This strategic move aids in balancing the energy grid, offering both stability and reliability.
Furthermore, NTT’s broader group activities include the expansion of NTT DATA’s Global Data Centers. Over recent months, the division has secured land across North America, Europe, and Asia to bolster its data center capacity. Notably, operations are being planned in Milan to meet the growing demand for hyperscale and AI-ready infrastructure in Southern Europe.
The firm’s asset acquisitions continue in Japan and beyond. In Tochigi, Japan, the firm acquired land to establish two high-capacity data centers near Tokyo. Similarly, expansions are in motion in other locations such as London, Frankfurt, Osaka, Oregon, and Arizona. These projects collectively aim to deliver an additional 370 MW of IT capacity globally.
This expansion is part of a broader $10 billion investment extending through 2027, which strategically positions NTT to deliver scalable, AI-ready infrastructure, meeting evolving enterprise demands.
