Saudi Arabia commissions its largest battery energy storage system
8 February 2025
Saudi Arabia has officially commissioned its largest battery energy storage system (BESS) to the grid, signifying a pivotal advancement in the nation's renewable energy expansion endeavors. The 500 MW/2000 MWh BESS in Bisha, located in the southwestern Saudi Arabian province of ‘Asir, has been heralded by project proponents as the world's largest operational single-unit energy storage project.
Owned by the Saudi Electric Company (SEC), the Bisha battery storage facility comprises 122 prefabricated storage units, designed and manufactured by China's BYD. Each unit houses a 6 MW power conversion system (PCS) paired with four lithium iron phosphate (LFP) battery modules, each boasting a capacity of 5.365 MWh. This modular design facilitates optimal space utilization, streamlines system integration, and minimizes potential failure points.
The engineering, procurement, and construction (EPC) works for this project were executed by a consortium comprising the State Grid Corporation of China and Riyadh-based Alfanar Projects. Deploying the facility in the harsh desert environment posed significant challenges, including extreme temperatures and frequent sandstorms. To ensure long-term reliability, engineers refined installation methods and optimized commissioning processes to withstand these conditions.
The Bisha BESS is part of Saudi Arabia's broader strategy to bolster its renewable energy infrastructure, aligning with Vision 2030, the kingdom's long-term economic blueprint aiming to source 50% of its energy from renewable sources by 2030. Energy storage plays a crucial role in this transition, providing grid flexibility and enabling the integration of intermittent power sources like solar and wind.
This project is one of several large-scale battery storage initiatives underway in Saudi Arabia. Currently, the Saudi Power Procurement Company (SPPC) is tendering four additional 500 MW/2000 MWh BESS projects.The list of prequalified 33 bidders was released earlier in January, revealing Masdar, ACWA Power, EDF, and TotalEnergies as competitors for 15-year storage services agreements.
