UPDATER's New Venture into Battery Aggregation Business

Introduction
Tokyo-based UPDATER, driven by its mission to solve social challenges through business, is taking a significant step forward by launching a battery aggregation initiative. This venture is underpinned by their vision of transparent energy, known as the 'Visible Battery' concept. The company’s electricity retail service, 'Minna Denryoku,' which provides 100% renewable energy, has laid a solid foundation for this new endeavor. With a qualification for participation in the demand-supply adjustment market set for June 2026, UPDATER is prepared to leverage its experience in managing electricity supply to innovate how batteries are utilized in the future.

Visible Battery Concept
At the core of UPDATER's new venture lies the 'Visible Battery' concept, which emphasizes understanding the origin of the electricity stored in batteries. The company is actively seeking partnerships with power generation companies that resonate with this vision. UPDATER aims to advocate for the importance of battery tracking and establish a 'Visible Battery Network' that collaborates with stakeholders to address the growing significance of energy transparency.

The initial focus will be on grid-connected batteries, with an expansion into household and co-located generation sources planned by 2030. The ambition is to grow the 'Visible Battery Network' to reach a scale of 1 GW by the end of the decade.

Technological Advancements
To support this initiative, UPDATER has begun developing tracing technologies for battery charging and discharging with the Tokyo University Graduate School's Tanaka Laboratory. The goal is to create logical frameworks that catalog the origin and attributes of electricity based on battery usage history. This aligns with UPDATER's broader goal of making the energy transfer from batteries transparent. If successful, the initiative will unravel the complexities that have traditionally obscured battery usage.

Market Context and Challenges
The volatility of power generation through solar and wind sources has intensified the demand for demand-supply adjustment capabilities within the energy market. As new players flood the battery market, regulations established by the government in March 2026 are forcing a reevaluation of purchasing volumes and price ceilings, contributing to falling battery trading prices. If UPDATER wishes to sustain long-term profitability, they must innovate beyond competing on price and scale alone.

Historically, once energy is stored in batteries, its origin becomes difficult to trace, leading to significant transparency issues. Even renewable energy can lose its identity when stored, leaving many unanswered questions about the electricity’s source, such as who produced it and how. The industry is rapidly expanding, yet these concerns linger, as evidenced by the substantial increase in battery capacity contracts in late 2025, highlighting the pressing need for a solution.

UPDATER believes that establishing a 'Visible Battery' marketplace will become crucial as societal expectations for transparency grow. Their extensive network of over 1,100 visible power generation sources enables them to track the origin of electricity and cement long-standing relationships with operators who share their commitment to transparent energy practices.

Foundation of the Initiative
The 'Visible Battery' concept is predicated on two fundamental pillars: better battery utilization and the formation of a robust network. To define optimal battery use, UPDATER will establish sustainable procurement policies that align with their ethical guidelines. This includes prioritizing collaboration with entities that uphold environmental integrity and community agreement in their operations. Additionally, UPDATER plans to incorporate strategies for the lifecycle of battery systems, including considerations for reuse and proper disposal.

In terms of building and expanding networks, UPDATER recognizes the role of batteries not only in stabilizing energy supply but also as key resilience hubs during disasters. Therefore, creating localized networks that enhance energy accessibility and resilience will shape the strategy for developing their Visible Battery Network.

Roadmap to Success
The initial phase of the initiative emphasizes aggregating low-pressure grid-connected batteries and is set to launch in areas with the greatest business potential. Subsequent phases will broaden to include higher voltage systems and various deployment models, steadily expanding UPDATER’s market presence and preparing them for the growing demands of the battery aggregation market.

With a target of scaling operations to achieve 1 GW capacity by 2030, UPDATER sees clear pathways for accomplishing this goal, powered by:
1. The rapid overall growth of the domestic battery market, which presents ample opportunity for strategic expansion.
2. Robust relationships cultivated through the 'Minna Denryoku' project, focusing on partnership rather than mere transactional interactions.
3. Advanced tracing technology designed to prove the origin of electricity, an innovation that positions UPDATER at the forefront of the energy transparency movement.

Conclusion
In summary, UPDATER is not only aiming to transform the battery sector but is also committed to addressing overarching societal challenges through enhanced visibility and ethics in energy consumption. This initiative has the potential to redefine the standards and expectations within the battery market, paving the way for a more sustainable and transparent energy operational landscape for the future.
