The Kingdom of Saudi Arabia has officially completed the grid connection of its landmark energy storage system (ESS) project with a nameplate capacity of 7.8 GWh. Once fully energized, the project will become the world’s largest operational battery energy storage system (BESS), representing a significant milestone for renewable energy development in the Middle East.
The project spans three sites in the southwestern regions of the Kingdom- Najran, Khamis Mushait, and Madaya. Sungrow served as the equipment provider and played a key role in project delivery, completing the manufacturing of more than 1,500 PowerTitan 2.0 systems in just 58 days and delivering the full project within a highly demanding schedule.
Sungrow’s PowerTitan 2.0 system adopts an all-in-one AC-DC block design, integrating embedded power conversion systems (PCS), pre-assembled battery containers, medium-voltage transformers, ring main units (RMU), and comprehensive factory testing. This integrated configuration significantly shortens onsite installation time. In addition, Sungrow deployed a dedicated local service team based in Saudi Arabia to support installation, commissioning, and grid connection activities.
The 7.8 GWh project marks the start of large-scale energy storage deployment in the Middle East. Its annual charging and discharging capacity is expected to reach 2.2 billion kWh, sufficient to meet the yearly electricity demand of approximately 400,000 households in Saudi Arabia.
The project makes a substantial contribution to Saudi Arabia’s Vision 2030 objectives and supports the global transition toward clean and sustainable energy.
Sungrow, a global leader in renewable energy technology, has been advancing sustainable power solutions for more than 28 years. As of June 2025, the company has installed 870 GW of power electronic converters worldwide. Sungrow is recognized as the world’s most bankable PV inverter and energy storage company by BloombergNEF.
