To accelerate the transition to renewable energy, PowerX is committed to providing energy storage solutions, an essential element of the new electricity infrastructure, as well as to creating a symbiosis between nature and industry. Covering a total area of 28,272 square meters, Power Base is equipped with an annual generation capacity of 5 GWh, which is equivalent to producing about 10,000 battery energy storage units per year. In addition to the battery assembly lines, the campus-like site also houses facilities such as R&D centers, offices and conference rooms. Designed to be the starting point for a sustainable, technology-driven future, Power Base will lead to the employment of more than 100 professionals, including engineers, technicians and manufacturing operators.
The plant is designed by Kazuyo Sejimaa world renowned architect who has worked on various projects in Japan and abroad, including the 21st Century Museum of Contemporary Art in Kanazawa*, which won the Golden Lion at the Venice Biennale Prize, the Louvre-Lens Museum*, a subsidiary of the Louvre Museum, and the Inujima “Art House Project” in Okayama, and the 21st Century Museum of Contemporary Art in Kanazawa*, which won the Golden Lion at the Venice Biennale. Thanks to close collaboration with Kazuyo SejimaPowerX envisions a “factory of the future” that coexists in harmony with nature in Tamano City and contributes to the revitalization of local communities.
- Terroir GW-scale factory for cost-effective, high-performance battery storage products
Battery-powered energy storage solutions are key enablers to overcome the challenges associated with the widespread adoption of electric vehicles, increased demand for grid balancing, and the continued growth of renewables. To address these challenges, PowerX is establishing its own GW-scale battery factory, Power Base, to produce turnkey energy storage systems, including stationary grid-scale batteries, fast chargers for electric vehicles, marine batteries and household batteries. A portion of the capital raised from the first half of the Series A funding will fund the construction of Power Base*.

Power Base is located in Tamano City, Okayama Prefecture. Blessed with a mild climate and lush natural landscape, the city neighbors the shores of the Seto Inland Sea and is relatively protected from earthquakes and other natural disasters. once at home from Japan the shipbuilding industry, the city is surrounded by deep-water ports that can accommodate larger ships; its history as a naval town is also conducive to the recruitment of technical talent. Additionally, the main port of Tamano City, Port Uno, is the main gateway to the Setouchi Islands as well as the venue for the Setouchi Triennale, an international art festival. Inspired by the city’s favorable geographical position and natural resources, Power Base will prioritize sustainable and environmentally friendly manufacturing through its automated assembly lines and production optimization.
- “Factory of the future” designed by the renowned in-house architect Kazuyo Sejima
In addition to serving as a manufacturing base for battery storage solutions that ensure an uninterrupted supply of energy generated from natural resources, Power Base envisions providing a comfortable space that stimulates creativity and communication. These concepts are reflected in the architectural design by Kazuyo Sejimathe only Japanese female architect to win a Pritzker Prize.
The design takes advantage of the plant’s location at a canal close to Port Uno, Honshu’s gateway to the islands of the Seto Inland Sea, and transforms existing buildings into a new workspace. The entire factory complex is covered by a large corrugated roof that visually blends into its natural surroundings, and each facility below is connected by the garden, creating a welcoming and engaging space. Beneath the edge of the curved roof is a conference room that overlooks the beautiful Seto Inland Sea. To make use of the existing buildings and the surrounding idyllic landscape, Sejima designed a “new workspace” that attracts and inspires people.
In addition to Sejima’s design, Power Base will help preserve local biodiversity as a sustainable factory that adopts automated assembly lines and other measures to achieve high production efficiency with minimal environmental impact.
