Sustainable Holdings' First Battery Storage Facility in Matsusaka

Sustainable Holdings, headquartered in Shibuya, Tokyo, has recently unveiled plans for the first grid-use battery storage facility in Matsusaka City, Mie Prefecture. This facility is set to undergo trial operations beginning in February 2026, with full commercial operations anticipated to start around June of the same year. The firm will utilize its proprietary battery brand, "Raptor," developed under an OEM agreement with REPT BATTERO. This project aims to bolter the power infrastructure in the region while contributing to a stable supply of renewable energy through participation in the energy market via aggregators.

What is a Grid-Use Energy Storage Facility?

A grid-use energy storage facility plays a vital role as infrastructure that assures a consistent power supply by storing excess energy and discharging it during peak demand periods. As the integration of renewable energy increases, the importance of such facilities in maintaining the stability of the electrical grid is becoming more pronounced.

The application of energy storage batteries is primarily seen across three markets:

1. Wholesale Electricity Market (JEPX): Buying and selling electricity based on price differences.
2. Demand-Supply Adjustment Market: Fine-tuning the instantaneous balance of supply and demand for electricity.
3. Capacity Market: Contributing to future supply stability by securing power sources.

Overview of the Matsusaka Energy Storage Facility

This storage facility marks the inaugural grid-use energy storage project for Sustainable Holdings. The construction will be executed by Yamaguchi Electric Works, a highly reputable firm with extensive regional experience, aimed at enhancing power stability in Matsusaka City.

Key Information

• - Location: Matsusaka City, Mie Prefecture
• - Capacity: Output 1,995 kW / Storage 8,340 kWh
• - Operational Timeline: Trial Run in February 2026, Full Operations in June 2026
• - Battery Type: Proprietary "Raptor" brand (OEM from REPT BATTERO) - 417 kWh liquid-cooled cabinet type
• - Construction Company: Yamaguchi Electric Works Co., Ltd.
• - Operation Method: End-users can participate in three markets (Wholesale / Demand-Supply Adjustment / Capacity) through an aggregator.

Features and Benefits

• - High Safety and Longevity: Thanks to the liquid-cooled design.
• - Adaptability: Its cabinet design allows flexibility to meet Japan's unique land conditions.
• - Stable Market Participation: Facilitated through aggregators for reliable engagement in market activities.

Uniqueness and Strengths: Combining Battery Brand and Developer Roles

Sustainable Holdings stands out as one of the few companies in Japan to simultaneously engage in providing its "Raptor" brand batteries while also serving as a developer for energy storage facilities.

• - High Efficiency and Durability: The "Raptor" batteries are manufactured through an OEM agreement with REPT BATTERO.
• - Comprehensive Development: By managing both manufacturing and development, the company can effectively oversee its energy storage business.
• - Promoting National Projects: Active in advancing the development of grid-use storage facilities, balancing stability and business viability.

This dual approach allows Sustainable Holdings to differentiate from competitors while delivering new value towards resolving Japan's energy challenges.

Future Outlook and Social Significance

Going forward, Sustainable Holdings is committed to the continual development and operation of grid-use energy storage facilities, contributing to regional power stability and the realization of a decarbonized society. By deploying the essential infrastructure for expanding renewable energy under its own brand and organizational structure, the company aims to support the stabilization of power supply and the overall energy transformation (GX) in Japan.
