CLOU Showcases at Smart Energy Week Tokyo, Targeting Japan’s Premium Energy Storage Market

From March 17 to 19, 2026, Smart Energy Week 2026, Japan’s largest, most specialized, and most influential international renewable energy exhibition, was held at Tokyo Big Sight. CLOU participated with its localized energy storage solutions, demonstrating both product strength and proven project delivery, and underscoring its firm commitment to the Japanese market.

Localized Products and Proven Projects Help Break Through Japan’s Market Barriers

At this year’s exhibition, CLOU closely aligned with local market needs in Japan and presented its Aqua-C2.5S mini series, a 10-foot fully liquid-cooled containerized energy storage system developed specifically for the Japanese market, together with supporting solutions. Backed by previously delivered benchmark projects, the product drew strong attention at the event.

The Aqua-C2.5S mini series is a localized solution purpose-built for Japan, designed to match local transportation conditions, terrain constraints, and application requirements. Featuring a compact and lightweight design, the system offers a base capacity of 2MWh and can be expanded to 2.5MWh. Even when fully configured, the battery container weighs less than 23 tons, allowing it to meet road transportation weight limits across most of Japan. Its compact form factor also enables flexible deployment on irregular sites. For example, in a 2MW/8MWh project, a fully integrated CLOU solution can reduce the total station footprint to as little as 133m², significantly improving land-use efficiency.

In December 2025, the Aichi 2MW/8MWh standalone energy storage power station project, built with the Aqua-C2.5S mini series, was officially commissioned. This marked CLOU’s first grid-side AC/DC integrated energy storage project delivered in Japan. The system was connected to the grid within one week after arriving on site, successfully meeting Japan’s demanding market access requirements and earning strong recognition from the local grid operator.

In an on-site media interview, Charles Gao, General Manager of Asia-Pacific Region, Overseas Energy Storage Business Center at CLOU, commented that the development and deployment of Aqua-C2.5S mini reflects CLOU’s core strengths in a highly concentrated way. Backed by three decades of experience serving complex power grids worldwide, the company has embedded grid-level safety, stability, and real-time responsiveness into product design. With full-stack in-house R&D, CLOU achieves deep optimization across BMS, PCS, and EMS, while also leveraging the broader ecosystem strengths of Midea Group. Together, these capabilities provide the Japanese market with energy storage solutions that combine high reliability, strong cost performance, and efficient delivery, laying a solid product foundation for long-term strategic expansion in Japan.

Japan: A Key Market for Validating Premium Capabilities and Establishing Technology Leadership

Japan’s energy storage market is now evolving from a policy-led phase into a dual-engine model driven by both market forces and structural system demand. Grid stability requirements, diversified business models, declining technology costs, and continued performance improvement are becoming the main drivers of growth.

Speaking about the strategic importance of Japan within CLOU’s global energy storage map, Gao noted that Japan represents a critical market for validating capabilities in advanced markets and establishing technical benchmarks. From a market perspective, Japan is known for some of the world’s strictest safety standards, most complex grid connection requirements, and highest customer expectations. Successfully entering this market and delivering projects that meet grid-level requirements, such as the Aichi project, serves as a compelling validation of technological capability, product quality, and project execution. It also provides strong credibility for expansion into other developed markets.

From a technology perspective, Japan’s unique constraints, including limited land availability, strict transportation regulations, and exposure to natural disasters, have driven targeted product innovation, such as the development of the compact 10-foot Aqua-C2.5S mini system with a total weight below 23tons. These solutions designed for Japan, in turn, enhance the competitiveness of the broader global product portfolio.

Strategically, Japan is one of the world’s leading markets in renewable energy development, and its energy transition pathway and grid challenges are highly forward-looking. Deep participation in this market enables earlier insight into the future needs of power systems and feeds those lessons back into technology development, helping maintain long-term global competitiveness.

Looking ahead, CLOU will continue to follow market trends and use its participation in Smart Energy Week Tokyo as an opportunity to further deepen the development of localized products and solutions. Supported by full-stack in-house technology and the broader ecosystem of Midea Group, the company aims to provide the Japanese market with energy storage products that combine hardware reliability with software intelligence. With a focus on the infrastructure-oriented evolution of energy storage, CLOU will continue building product systems with multiple grid-support functions, deepen its participation in Japan’s energy transition, and work together with local partners to unlock the market’s long-term potential, while driving high-quality growth in its global energy storage business.
