4.6MWh! GSL ENERGY's first commercial and industrial energy storage project in the Middle East officially launched

In May 2025, Shenzhen GSL Energy Co., Ltd. (hereinafter referred to as “GSL ENERGY”) officially launched its 4.6MWh energy storage project in Lebanon, marking the recognition of GSL ENERGY's integrated photovoltaic and energy storage solutions by customers in the Middle East.

I. Commercial and Industrial Energy Storage in the Middle East

The Middle East is referred to as a “dark horse” market for energy storage. Data shows that the power demand growth rate in the Middle East from 2024 to 2026 will reach 3%, with average carbon emissions per kilowatt-hour as high as 658g/kWh, far exceeding the global average of 480g/kWh. Additionally, the economy is significantly influenced by oil prices, leading to strong demands for carbon reduction and economic transformation.

As a global pioneer in commercial and industrial energy storage, GSL ENERGY possesses unique advantages and insights in global energy storage battery technology and commercial and industrial energy storage system integration. For this project, after thoroughly assessing the client's needs, GSL ENERGY customized a 2MWPCS and 4.6MWh energy storage battery system for the client, utilizing 16 120kW inverters for AC coupling, each housed in three 20-foot containers. The system integrates with the client's existing 3MW solar photovoltaic panels and PLC to achieve integrated photovoltaic energy storage operation, coordinating management of UPS, diesel generators, and other loads to enable both grid-connected and off-grid operation.

The Middle East region has an annual average solar radiation of over 2,000 kWh/m², receiving 22%-26% of the Earth's solar energy resources, with photovoltaic power generation costs at one-fifth of the global average.

Additionally, considering the Middle East's energy subsidy and electricity pricing policies, the project is estimated to generate direct peak-valley arbitrage of USD 295,000 per year, save demand charges of USD 80,000 to 120,000 per year, and achieve annual revenues exceeding USD 500,000 if participating in grid frequency regulation services. There are also standby capacity revenues of USD 100,000 to 150,000. The project reduces carbon emissions by 2,740 tons of carbon dioxide annually, generating annual carbon offset revenues of USD 137,000.

II. GSL ENERGY Photovoltaic-Storage Integrated Solution

The photovoltaic-storage integrated solution primarily consists of four components: photovoltaic power generation units, energy storage units, an energy management system (EMS), and grid-connected/off-grid control units. These modules work together to achieve a closed-loop “generation-storage-consumption” system.

GSL ENERGY's integrated photovoltaic-storage solution is widely applied in high-energy-consuming industrial and commercial enterprises, industrial parks, microgrids, and heavy-duty truck charging and storage scenarios. By leveraging peak-valley electricity price differentials, the investment payback period can be reduced to 3-5 years.

1. Photovoltaic-Storage Synergistic Control Technology

GSL ENERGY enables deep integration between photovoltaic and energy storage systems. Under the premise of ensuring safe operation, the system optimizes control to effectively eliminate peak-valley differences, smooth load fluctuations, and achieve short-term flexible capacity expansion. It improves the operational efficiency of power equipment, compensates for load fluctuations, and, in scenarios where power cannot be fed back into the grid, can prevent reverse power flow by adjusting photovoltaic power generation and energy storage charging.

2. High-Safety Energy Storage Technology

To address the thermal runaway risk of lithium-ion batteries, GSL ENERGY enhances safety through three aspects: battery cells (world-class Grade A cells), structure (such as liquid cooling/air cooling cooling systems), and management (BMS battery management system, real-time monitoring of voltage, temperature, and SOC). The BMS adopts a dual-layer architecture design, improving precise control capability by 5%.

3. Strong Networking Capabilities

The Middle East region has weak grid infrastructure, few cross-border transmission lines, and high-temperature, dusty environments that impose stringent requirements on the stability of energy storage systems. GSL ENERGY's energy storage solutions possess strong networking capabilities, supporting various transmission protocols to help customers achieve intelligent, efficient operation and enhance the application value and flexibility of energy storage systems within power systems.

The successful operation of this project marks the beginning of a new chapter in GSL ENERGY's Middle East journey. The company will continue to adhere to the principles of high safety, reliability, and efficiency, deepening its expertise in the photovoltaic storage field to enhance the economic value of customers' energy storage assets throughout their lifecycle and actively contribute to the global transition toward green energy.
