Introduction
Industrial facilities with heavy-duty equipment such as forging, smelting, and machining machines face continuously rising electricity costs. High and fluctuating power demand not only increases operational expenses but also places pressure on local grids.
To address these challenges, a manufacturing plant in Zhuji, China deployed a high-efficiency battery energy storage system (BESS) powered by Enjoypowers PCS, achieving significant cost reduction and improved energy efficiency.
Project Overview
The project consists of 11 energy storage cabinets, each with 215 kWh / 100 kW, forming a total system capacity of:
- Energy Capacity: 2.365 MWh
- Power Rating: 1.1 MW
- Configuration: Two-charge two-discharge daily operation
- Annual Discharge: ~170 MWh
Each cabinet features a high-density integrated design, including PCS, EMS, BMS, thermal management, and fire protection, ensuring safe and stable long-term operation.
Energy Cost Savings
By shifting electricity use from peak periods to lower-cost valley periods, the system helps the factory significantly lower its energy bills.
With an annual discharge of 170 MWh, the plant achieves an estimated savings of:
→ USD 32453.53 per year
This reduction directly contributes to lower operational costs, improved energy efficiency, and more sustainable industrial production.
Why Enjoypowers PCS
The project uses Enjoypowers Power Conversion Systems (PCS), known for:
✔ Strong Grid Adaptability
Handles complex industrial grid conditions with enhanced stability.
✔ High Dynamic Response
Achieves millisecond-level full-load charge and discharge switching, ideal for high-load manufacturing environments.
✔ High-Density Integration
Reduces installation footprint and simplifies deployment.
✔ Reliable Operation for 24/7 Industries
Supports continuous manufacturing without compromising performance.
Benefits for Industrial Users
The Zhuji project demonstrates how modern industrial energy storage solutions can create direct value:
- Lower electricity costs through peak shaving and valley filling
- Improved power quality and reduced load impact
- Enhanced grid stability
- Support for cleaner and greener manufacturing
- High return on investment for energy-intensive industries
This makes battery energy storage an ideal choice for factories with heavy loads such as forging, casting, machining, electronics manufacturing, and metal processing.
Conclusion
The 2.365 MWh energy storage system in Zhuji showcases the effectiveness of integrating Enjoypowers PCS into industrial facilities. This project not only delivers measurable economic savings but also promotes sustainable development by optimizing energy use and reducing grid stress.
As more manufacturers seek to reduce energy costs and carbon footprint, industrial energy storage systems will continue to play a key role in future-ready factories.
