Headline: Japan's Largest 2GWh Energy Storage Project Launches as Gurin Energy and Saft Drive Energy Transition

1. Project Overview: 2GWh Storage System in Soma, Fukushima - Japan's Largest BESS

• Location: Soma City, Fukushima Prefecture

• Developer: Singapore-based Gurin Energy

• System Integrator: Saft (a TotalEnergies subsidiary)

• Phase 1 Capacity: 1GWh (240MW/4-hour discharge)

• Total Planned Capacity: 2GWh (two-phase completion by 2030)

• Technology Solution: LFP batteries, liquid cooling, i-Sight cloud monitoring, integrated third-party PCS+EMS

• Construction Start: Early 2026

2. Business Model: Hybrid Revenue Approach Tests Japan's Storage Market Viability

• Primary Revenue Streams: Grid services (frequency regulation, peak shaving), energy arbitrage, tolling agreements

• Market Challenge: Limited subsidies require market-based operation

• Gurin Energy Perspective: "Japan's #5 power market needs flexibility - GW-scale makes commercial sense"

3. Why Fukushima? Policy Support Meets Grid Demand

• Policy Backdrop: Priority reconstruction zone post-2011 with clean energy incentives

• Grid Value: Key Northeast transmission node improves renewable integration

• Demonstration Value: Operational model for nationwide replication

4. Saft's Role: Full-stack Storage Integration

• Core Tech: LFP battery containers with liquid cooling

• System Integration: Third-party PCS/EMS compatibility

• Lifecycle Services: Turnkey installation to long-term maintenance

• Strategic Impact: European storage standards enter Japanese market

5. Japan's Storage Market: From Laggard to Growth Phase

• Current Status: Just 2GWh deployed (2024) - R&D/commercialization stage

• Growth Drivers: Market liberalization, VPP development, EV integration

• Project Significance: Template for "active grid management" storage

6. Conclusion: 2GWh Represents Japan's Energy Inflection Point

• Partnership Impact: Global players aligning policy, market and
