PowerX Commercializes Scalable Modular Data Centers

TOKYO, JAPAN — PowerX, Inc. (Head Office: Tamano City, Okayama Prefecture; Director, President and CEO: Masahiro Ito; Securities Code: 485A) has commercialized "Mega Power DC," a modular data center solution that applies expertise gained through the development and manufacturing of battery energy storage systems (BESS). By integrating servers, power systems, and cooling equipment, along with large-capacity BESS, into a single container, the product significantly reduces construction timelines and costs while enabling flexible scalability. PowerX will conduct market validation with partners, targeting the start of mass production from 2027.

The rapid adoption of generative AI is driving a surge in computing demand across Japan. However, constraints such as limited grid capacity and prolonged construction timelines have left Japan's AI data center infrastructure significantly behind the United States, making the expansion of this infrastructure an urgent priority. Against this backdrop, PowerX recognized that its expertise in container design, DC power control, cooling technologies, and mass production capabilities—honed through the development and production of large-scale BESS—could be effectively applied to data center construction, and decided to commercialize "Mega Power DC," a scalable modular data center.

The system is built on a 10-foot container and can house up to six industry-standard 42U racks for GPUs and other hardware. An optional 800 kWh LFP-based BESS ensures uninterrupted operation during power outages and enables deployment in areas with power constraints. Unlike traditional building-based data centers, this modular solution requires no major construction, reducing lead times from 4–5 years to approximately one year and lowering deployment costs by an estimated 25%*.

Furthermore, the container-based packaging allows flexible placement even on constrained sites, with scalability ranging from a single unit to multi-unit configurations depending on requirements. The computing configuration—including GPUs, CPUs, and networking equipment—can be customized to meet client specifications, with PowerX assembling units from designated components and shipping directly from its factory.

Watch the announcement

In preparation for the start of mass production in 2027, PowerX today begins accepting inquiries from prospective customers and business partners interested in deploying the product. Additionally, the company has signed a memorandum of understanding with Internet Initiative Japan Inc. (IIJ) (Headquarters: Chiyoda-ku, Tokyo; Representative Director and President: Yasuhiko Taniwaki; Securities Code: 3774) to explore collaboration on the development and expansion of power and digital infrastructure utilizing large-scale BESS and containerized data centers**.

Through partnerships across a wide range of industries, PowerX will advance the integrated development and expansion of power infrastructure and computing platforms, contributing to Japan's energy self-sufficiency and the construction of resilient social infrastructure for the AI era.

^{*This estimate is based on the Levelized Cost of Computing (LCOC), comparing data center infrastructure costs (excluding IT equipment) per MW of power capacity (construction + 5-year OPEX). IT equipment, being a global standard, is treated as a common assumption. Conventional DC assumptions: Power capacity of 50,000 kW; CAPEX includes land, building, on-site electrical facilities, etc. (excluding IT equipment), evaluated as a present value over 20 years. Modular DC assumptions: Power capacity of 200 kW × one 10-ft modular DC; CAPEX includes containerization, land, installation work, etc. (excluding IT equipment); time value is expressed as a present value over the years to COD. In both cases, OPEX covers operations, maintenance, and monitoring (excluding IT equipment) over a 5-year evaluation period. Under these assumptions, the cost per MW of power capacity is ¥2.47 billion for a conventional DC compared to ¥1.77 billion for Mega Power DC, resulting in an estimated cost advantage of approximately 25%. This estimate is a simulation based on certain assumptions and does not guarantee actual costs.
