Project Overview
Project Type: Commercial & Industrial Behind-the-Meter Energy Storage – Electricity Cost Management & Backup Power
Commissioning Date: June 2025
Location: Lisbon Industrial Park, Portugal
Client: A Large-Scale Food Processing Manufacturer
Technical Solution
TSTYNICE designed and deployed a 1.5 MW / 3 MWh containerized battery energy storage system to help the client optimize electricity expenses and provide backup power for critical production processes during grid outages.
Equipment Supplied
System Configuration: 1.5 MW / 3 MWh
Battery Technology: Long-cycle-life Lithium Iron Phosphate (LFP)
System Integration: Single 20-foot all-in-one outdoor container
PCS: 1.5 MW bi-directional inverter with seamless grid-tied/off-grid switching capability
EMS: Intelligent Energy Management System with load forecasting and electricity price strategy optimization
Key Features
Dual-mode Operation: Supports grid-tied "peak shaving & valley filling" and off-grid "critical load support" modes
Fast Transition: Islanding transition time < 20 ms to ensure production continuity
Intelligent Strategy: AI-optimized charging/discharging strategy based on time-of-use tariffs and demand charges
Modular Design: Scalable battery architecture for future capacity expansion
Compact & Efficient: Total footprint < 30 m² with high-efficiency thermal management
Project Execution
Total Project Timeline: 5 months (from energy audit to commissioning)
Key Milestones:
Energy Audit & Simulation: Analyzed the client's annual load profile and simulated storage benefits.
Customized Design: Optimized system layout based on plant infrastructure and grid connection point.
Rapid Deployment: 95% pre-assembled containerized system, requiring only 3 weeks for on-site installation and commissioning.
Local Compliance: Ensured full compliance with Portuguese low-voltage grid connection regulations and safety standards.
Operational Results
Cost Savings: Achieved approximately 28% reduction in monthly electricity costs, primarily by reducing peak demand charges and utilizing off-peak electricity.
Demand Control: Successfully maintained the contracted maximum demand below the target threshold, avoiding penalty fees.
