Google Group Company to Construct Data Center in Cosmo Park Kata Industrial Estate in Wakayama City

The Cosmo Park Kata industrial estate in Wakayama City is a 252-hectare industrial area developed on the site where soil was extracted for the construction of Kansai International Airport.

Although the Wakayama Prefecture Land Development Corporation advanced the development, economic downturns quickly stalled the plans. The prefecture rented some of the land to promote industrial recruitment, but 87 hectares remained unsold, becoming a longstanding issue.

In this context, more than 40% of this land, totaling over 37 hectares, was sold to Ase LLC, a group company of the American IT giant Google, based in Tokyo.

The total sale price of the land is reported to be 5.94 billion yen.

Furthermore, according to Wakayama Prefecture, there are plans to construct a data center to enhance data processing speed and stability, although the details of the project plan have not been disclosed.

The process of contracting for the sale of the land is set to proceed.

Summary

With a sharp increase in cloud demand for generative AI, American Microsoft is also rushing to invest in data centers in Japan. Microsoft activated several data centers in western Japan in February last year. Google has also been operating Japan’s first data center in Inzai City, Chiba Prefecture, since March of last year. Moreover, expansion in regional areas is expected to accelerate, and we will continue to provide updates on these developments.

In December 2023, Arteria Networks Corporation and AT Tokyo Corporation decided to lay a communication optical fiber cable across Tokyo Bay, a first in Japan, connecting the Toyosu-Ariake area, which hosts a concentration of IT companies, with the Shibaura-Shinagawa area.

What underlies this decision?

The backdrop for the installation of the communication optical fiber cable includes the rapid increase in communication traffic due to changes in work styles, the rise of rich content such as video streaming, and the spread of DX, AI, and IoT, necessitating the enhancement of optical communication facilities that are vital to data centers accumulating massive data. Furthermore, communication networks, being essential social infrastructure, must not be severed under any circumstances.

To meet such societal demand, the decision was made to lay a communication optical fiber cable across Tokyo Bay, ensuring a route for data centers located on islands without relying on bridges. A notable feature is the use of the arc advancement method, considering environmental conservation.

AT Tokyo is working towards establishing a Central Third Center in the Shibaura-Shinagawa area by July 2024 as a network connection hub comparable to existing data centers, contributing to Tokyo’s information infrastructure, which brings together major financial businesses, content providers, and telecommunications operators from Japan and around the world.

Arteria Networks aims to support Tokyo as a leading technology industry and international financial city by connecting data centers in the Toyosu-Ariake area and the Shibaura-Shinagawa area provided by AT Tokyo with a high-capacity, low-latency cable route via the shortest path, offering flexible and diverse communication services.

Reasons for connecting data centers via the Tokyo Bay crossing route

The installation of this communication optical fiber cable aims to connect the Toyosu-Ariake and Shibaura-Shinagawa areas through redundant land and sea routes, enabling the use of a more reliable network infrastructure.

Existing land cable routes are at risk of flooding and liquefaction during disasters, potentially severing the network. The Tokyo Bay crossing communication optical fiber cable, installed using HDD (Horizontal Directional Drilling) method, crosses Tokyo Bay in a continuous underground conduit, ensuring a high-capacity, high-speed communication by securing an alternate route to the land, resistant to damages from ship anchors and other hazards.

Arteria Networks’ strategic initiatives in the data center business

The Inzai area in Chiba Prefecture has been deemed suitable for data center operations due to the strength of its ground, high accessibility to Tokyo and Narita, and connectivity to the submarine cable landing stations in northern Ibaraki and southern Boso in Chiba. In 2021, Arteria Networks announced the installation of a dedicated line facility capable of up to 100Gbps at the NRT10 data center being constructed by MC Digital Realty in the Inzai area of Chiba Prefecture. The laying of the communication optical fiber cable across Tokyo Bay is backed by Arteria Networks’ longstanding strategic efforts, with further advancements expected in the future.

As previously reported, NTT and Tokyo Electric Power have jointly established a new company and agreed to jointly develop data center and battery storage businesses. This time, I will focus on introducing the battery storage business.

Outlook for the Battery Storage Business

NTT Anode Energy and Tokyo Electric Power Holdings have agreed to expand the application area of batteries and reduce costs at the Tsumagoi Battery Storage facility. This storage facility will use lithium-ion batteries, with a capacity of 9.3MWh and an output of 2MW.

Moving forward, both companies plan to use their assets and know-how in electricity and telecommunications to meet increasingly sophisticated social needs, such as carbon neutrality, and aim to create new value and become leaders in building a sustainable society.

So, why focus on battery development?

The Importance of Batteries in Data Center Operations

Data centers consume a massive amount of electricity, necessitating the use of renewable energy. However, ensuring a stable supply of vast amounts of power is a challenge. This is because the power generation from renewable energy varies depending on weather and time. While short-term fluctuations can be covered by UPS (Uninterruptible Power Supply) and emergency generators, they are not sufficient for frequent disruptions and pose a critical flaw for data center services. The use of batteries allows for coping with these fluctuations in power generation, enabling a stable supply of renewable energy. This is expected to promote the use of environmentally friendly energy in data center operations. Although the use of batteries has been considered before, their implementation in data centers has not progressed due to both the capacity of power storage and cost.

Expectations for the Technology and Initiatives of Both Companies

Battery technology is an extremely important theme across the industrial world, particularly in the data center industry. The path to addressing this theme is anticipated to advance through the establishment of a new company by NTT and Tokyo Electric Power, focusing on the development of large-capacity batteries in MW units and cost reduction, leading to widespread adoption in the data center industry.

Tokyo Electric Power Holdings and NTT announced on December 19, 2023, two new initiatives in their collaborative business.

Data Center Business

The first is the data center business. NTT Data Group, NTT Global Data Centers, and Tokyo Electric Power Grid have agreed to jointly develop and operate a new company in the Inzai Shirai area of Chiba Prefecture, aimed at establishing a data center. They plan to establish a special purpose company within the fiscal year 2023, develop a data center with a power capacity of 50 MW, and aim to open and start services in the second half of fiscal 2026.

With the proliferation of generative AI, there is an expected increase in demand for data centers. Both companies have indicated a policy to leverage their expertise to aim for an advanced data center model, taking into account the realization of carbon neutrality.

Storage Power Plant Launch

The second initiative is the storage power plant business by TEPCO Holdings and NTT Anode Energy. In November, they established a limited liability company, ‘Tsumagoi Storage Power Plant LLC’, in Tsumagoi Village, Agatsuma District, Gunma Prefecture. They are preparing for the construction of the storage power plant and other preparations, aiming to start the business in 2025.

In the context of advancing the introduction and utilization of renewable energy towards the realization of carbon neutrality by 2050, issues such as securing adjustment power and enhancing the power system that become necessary are becoming evident.

To address these issues, TEPCO Holdings and NTT Anode Energy have been utilizing batteries in their efforts. By bringing together the expertise both companies have cultivated and collaborating in the increasingly necessary storage power plant business, they aim to expand the application area of batteries, reduce costs, and further develop the storage power plant business.

Future Trends Worthy of Attention

In 2020, the power consumption of data centers accounted for 2.1% of the total power consumption (913.5 billion kWh), an increase from about 1.4% in 2018. Furthermore, according to a report by the International Institute for Environmental Economics, if the trend of increasing computational load continues into the future, it is expected to reach 90 TWh domestically by 2030.

The establishment of new companies by NTT and TEPCO, Japan’s largest data center operators, to meet the growing power demand in a carbon-neutral way is garnering attention from the entire industry.

As this is an important topic in discussing Japan’s data center market, we will continue to follow these developments.”
