In June 2025, GSL ENERGY completed the deployment of a large-scale commercial and industrial energy storage solution for a manufacturing facility in Lebanon.

Facing increasing electricity costs and the challenge of maintaining a stable power supply, the factory integrated solar generation with advanced battery storage technology to improve energy efficiency and reduce dependence on conventional power sources.

GSL ENERGY provided a customized 2MW Power Conversion System (PCS) combined with a 4.6MWh lithium battery energy storage system, creating an intelligent hybrid energy solution capable of coordinating solar power, battery storage, and diesel generator backup.

The system supports efficient energy scheduling, peak demand management, and emergency power backup, helping the factory achieve greater energy independence and operational stability.

System Configuration

The complete hybrid energy storage solution includes:

• 3MW Solar PV System
  • Installed on factory rooftops and nearby hillside areas
  • Provides renewable energy generation for daily operations
• 2MW PCS (Power Conversion System)
  • Controls bidirectional energy conversion between solar, battery, and loads
  • Enables intelligent charging and discharging strategies
• 4.6MWh Battery Energy Storage System
  • Two units of 2.3MWh battery storage systems
  • High-performance lithium battery technology for long-duration operation
• 3MW Diesel Generator Backup
  • Provides additional power security during extended outages or low renewable generation periods
• Central UPS & Energy Management System
  • Ensures uninterrupted critical loads
  • Enables centralized monitoring and real-time system control

Key Benefits

Lower Energy Costs

The battery storage system stores excess solar energy and releases it during peak electricity demand periods, reducing grid electricity consumption and operating expenses.

Reliable Industrial Power Supply

The integrated battery, UPS, and diesel generator system provides multiple layers of backup protection for continuous factory operation.

Intelligent Energy Management

The EMS platform optimizes power flow between solar PV, battery storage, generators, and factory loads for improved efficiency.

Scalable C&I Energy Storage Solution

The modular design allows future expansion according to the factory’s growing energy requirements.
