Background: Addressing Peak Load and Energy Cost Challenges
Against the backdrop of Europe’s energy structure transformation, industrial enterprises are facing increasingly severe electricity challenges. Rising electricity prices, uneven grid load, and stricter carbon emission controls necessitate more efficient and economical energy strategies while ensuring production continuity.
SCU, leveraging its leading technology in smart energy storage, provided a European industrial customer with a 20ft containerized energy storage system with a capacity of 500kW/1MWh. This system, through peak shaving, valley filling, energy storage arbitrage, and energy dispatch, achieved the customer’s dual goals of optimizing electricity costs and transitioning to a green and low-carbon model.
Customer Needs: The Dual Pressure of High Load and Fluctuating Electricity Prices
Industrial plants consume significant amounts of energy daily, experience distinct peak loads on equipment, and are frequently affected by fluctuating electricity prices. Enterprises aim to achieve the following goals by deploying energy storage systems:
- Peak shaving to reduce electricity costs: Storing energy during off-peak hours and discharging it during peak hours avoids peak-hour charges.
- Enhancing energy self-management capabilities: Reducing dependence on the grid and increasing the flexibility of power dispatch.
- Participating in the electricity market to achieve revenue growth: Connecting the energy storage system to the electricity trading market and selling electricity back to the grid at appropriate times to generate additional revenue.
Solution: 500kW/1MWh Containerized Energy Storage System
SCU provides customers with a 500kW/1MWh 20ft energy storage system container using high-safety lithium iron phosphate (LFP) batteries, featuring long cycle life and excellent stability. The system is equipped with a 500kW bidirectional PCS and features an advanced battery management system(BMS) and energy management system (EMS) for real-time monitoring and intelligent dispatch of electricity.
Energy Storage System Advantages:
- Intelligent Peak Shaving Strategy: Automatically schedules charging and discharging based on electricity price changes.
- High-Efficiency Energy Conversion: The PCS boasts high conversion efficiency, reducing energy loss.
- Flexible Grid-Connected Operation: Enables switching between grid-connected and off-grid operation modes.
- Safe and Reliable Design: Modular structure, fireproof and heat dissipation systems provide dual protection.
- Power Grid Interaction Capability: Enables energy feedback and ancillary service revenue.
Project Results: Dual Improvement in Economic and Environmental Benefits
- Significantly Reduced Electricity Costs: Through peak-valley arbitrage and energy scheduling, the company’s annual electricity expenditure has significantly decreased.
- Expanded Revenue Channels: The energy storage system sells excess electricity back to the grid during non-production periods, generating additional revenue.
- Enhanced Energy Independence: Reduces dependence on the main grid, improving production continuity and energy security.
- Contributing to Carbon Neutrality Goals: By improving energy utilization and the proportion of green energy use, carbon emissions are reduced, responding to European low-carbon policies.
