In June 2025, GSL ENERGY successfully delivered and commissioned a 2MW / 4.6MWh liquid cooling commercial and industrial energy storage system for a plastic manufacturing facility in Lebanon—a region frequently affected by grid instability and electricity shortages.
Customer Background & Challenges
The client operates a large plastic production plant, supported by a 1 MWp Fronius solar array and a 2 MWh Solax on-grid inverter system. However, due to unreliable grid power and regular outages, the customer needed a dependable, off-grid commercial energy storage system to ensure uninterrupted operation.
Key project requirements included:
Two sets of 1MW / 2MWh commercial battery storage units
Full off-grid operational capacity
Integration with an external diesel generator for backup support
A customized Energy Management System (EMS)
Custom logo branding on all equipment
Installation via crane hoisting onto a dedicated platform due to space constraints
Tailored GSL ENERGY Solution
GSL ENERGY provided a turnkey AC-coupled hybrid energy storage solution—model PCE CESS-2MW-4.6MWh—designed specifically for commercial and industrial energy storage needs. The system includes:
Two 1MW Power Conversion Systems (PCS)
Two 2.3MWh advanced liquid-cooled battery cabinets
A fully customized EMS with intelligent control and remote monitoring
This commercial energy storage system is tightly integrated with the factory's solar infrastructure, enabling both on-grid and off-grid operation. It supports advanced functions such as:
Peak shaving and load management
Energy arbitrage for operational cost reduction
Emergency backup during power failures
Grid-forming capabilities for full energy autonomy
Deployment & Technical Execution
Given the site’s limited accessibility, all equipment was lifted and installed using a crane onto a custom-built platform—demonstrating GSL’s flexible deployment capabilities in real-world industrial scenarios.
GSL ENERGY’s engineering team provided full technical support on site, including:
Installation guidance and supervision
System commissioning and EMS optimization
Compatibility testing with solar and diesel generator sources
Staff training and long-term operation support
