Optimize costs and improve operational efficiency with energy storage
With industrial electricity tariffs varying sharply across peak hours and strict power quality requirements for production lines, BESS (Battery Energy Storage System) energy storage has become a vital strategic investment for manufacturers and industrial parks.
The system acts as a “smart power bank”: it automatically charges during off-peak hours (low tariff) or from surplus rooftop solar, then discharges precisely during peak hours to eliminate costly peak loads.
Peak shaving
Peak Shaving optimized for the EVN 3-tier tariff.
< 10ms response
Differential switching prevents instantaneous voltage sags.
SVG reactive compensation
Automatically stabilizes Cosφ > 0.98.
Concept & core structure
What is a BESS energy storage solution?
A BESS (Battery Energy Storage System) is an advanced industrial-grade lithium battery package that integrates a PCS (Power Conversion System), a smart energy management system (EMS) and an active fire protection system.
The system stores energy when it is abundant or cheap and releases power flexibly on real-time demand from the plant’s load dispatch station.
Industrial-grade LiFePO4 cells
Outstanding durability of over 6,000 charge/discharge cycles, fully resistant to fire and explosion at high temperatures.
Market size forecast & trends
Battery energy storage system (BESS)
According to international experts, the BESS battery storage market is growing exponentially amid the global green energy transition and the Net Zero commitments of industrial supply chains.

Practical value
Key benefits of investing in a BESS
Lower electricity operating costs
Minimize reliance on expensive peak-hour grid power (up to 3,500 – 4,500 VND/kWh). Instantly cut penalty charges for apparent power exceeding the registered threshold.
Stable production operations
Provides continuous backup power with millisecond transfer time, protecting sophisticated automated lines from blackouts or sudden voltage fluctuations that damage workpieces.
Solar system optimization
Pairs perfectly with existing rooftop solar systems. Stores 100% of surplus daytime output instead of curtailing it (Zero-Export), then releases all stored energy for night shifts.

Real-world BESS application scenarios
Multi-tier energy storage solutions that optimize electricity costs, stabilize loads and add economic value with All-in-One Cabinet & Containerized ESS configurations.
Scenario 01
Peak shaving & load shifting
Automatically charges batteries during low-tariff periods (off-peak/normal hours) or from surplus solar, and discharges during peak hours to eliminate peak loads, lowering electricity bills and maximum demand charges.
- Economic benefit: 15% – 30% savings on total electricity costs.
- Smart dispatch: Real-time optimization of the 3-tier tariff.
- Payback period: An estimated 3 – 5 years depending on load profile.
Scenario 02
Emergency backup power & voltage sag protection
Ultra-fast automatic switching (< 10ms – 20ms) during grid outages or momentary voltage sags, fully protecting sensitive production lines in metallurgy, textiles, plastic molding and microelectronics cleanrooms.
- Seamless switching: UPS-grade On-Grid/Off-Grid Seamless Switching.
- Productivity protection: Eliminates 100% of the risk of workpiece damage from power loss.
- Hybrid support: Integrates diesel generators with optimized fuel consumption.
Scenario 03
Renewable energy integration & zero-export mitigation
Fully resolves curtailment and Zero-Export constraints on rooftop solar. The BESS absorbs 100% of surplus daytime solar power and supplies it to night-shift loads or during peak hours.
- Maximum utilization: Raises clean energy self-consumption to 95% – 100%.
- Power smoothing: Ensures stable generation output (Smooth Solar Output).
- Green credentials: Meets CBAM, RE100 & ESG Scope 2 assessment criteria.
Scenario 04
EV fast charging stations & service infrastructure
Integrated BESS supports high-power EV charging stations (DC Fast Charger) without upgrading existing transformer capacity or power lines.
- Infrastructure relief: Eliminates substation overload bottlenecks during peak charging hours.
- Automatic reactive compensation: SVG / Q-at-night capability for voltage stability.
- Long-term benefits: Optimizes revenue from electricity sales and green charging services.
