Shenzhen-listed Sungrow Power Supply said Tuesday it will build the world’s largest battery energy storage project in Saudi Arabia, Kallanish reports.

The company inked an agreement with Saudi investment company Algihaz Holding to jointly build a 7.8-gigawatt-hour BESS project in the kingdom. This will be done across three sites: Nairan, Madava and Khamis Mushait.

Equipment delivery will begin this year, with full capacity grid connection slated to be operational in 2025. The project will feature nearly 7.8 million battery cells, and help improve stability and reliability of the Saudi power grid.

Sungrow says the efficient and safe operation will be ensured through intelligent energy management systems (EMS) and battery management systems (BMS), from battery cells to energy storage power stations.

During the project design and construction stage, Sungrow will also carry out system simulation, conduct field-level grid hardware-in-the-loop (HIL) experiments, simulate the actual situation of the local grid, verify the consistency of field-level strategies, and ensure that the energy storage system is safely and stably connected to the grid. Its life cycle is expected at over 15 years.

Sungrow will deploy more than 1,500 PowerTitan2.0 liquid-cooled energy storage systems. It will use an integrated AC storage design with high energy density, helping customers save 55% of land area.

The equipment can be pre-installed and pre-adjusted before leaving the factory, and connected to the grid upon arrival. At the same time, relying on intelligent manufacturing capabilities and a global sales and service system, it can meet the needs of extremely fast project delivery.

Also on Tuesday, the Chinese manufacturer announced it will equip the Vilvoorde BESS project in Belgium, under development by Engie. The 800-megawatt-hour (200 MW) system will be one of the largest ever installed in Europe.
