Launch of Aggregation Service Bundling Low-Voltage Grid Storage Systems

On May 27, 2026, Sassor Inc. (Headquarters: Shibuya-ku, Tokyo; Representative Director: Shuichi Ishibashi) announced the commencement of fleet operation aggregation services for low-voltage grid storage systems. In this service, the company bundles multiple low-voltage grid storage systems to form an aggregation unit of 1MW or more, providing integrated support for available capacity management, EMS linkage, remote monitoring and control, bidding planning, performance management, and settlement reports. Aiming for multi-market operations combining arbitrage on JEPX (Japan Electric Power Exchange), capacity markets, and supply-demand adjustment markets, the company provides an operational foundation for utilizing low-voltage storage systems as distributed adjustment resources. The utilization of low-voltage resources has become a key theme in the supply-demand adjustment market starting in fiscal year 2026. On the other hand, low-voltage storage systems have small capacities per site, making it difficult to meet market requirements individually. The company supports the early commercialization and market participation of low-voltage storage systems through aggregation operations that take into account SOC, battery degradation, communication status, shutdown risks, and measurement methods for each site.
