Saudi Arabia is rapidly emerging as one of the world’s largest markets for battery energy storage systems (BESS), with over 6.2 GW of upcoming capacity and a long-term target of 48 GWh by 2030. The Kingdom has already tendered more than 26 GWh of storage projects, with over 6 GW under construction or in advanced development.

The largest upcoming BESS projects in Saudi Arabia, including BYD-SEC Phase 3 (Five Sites), HiTHIUM Tabuk BESS, Al-Muwaih BESS ISP, Haden BESS ISP, and Al-Kahafa BESS ISP, are part of its Vision 2030 strategy to integrate 50% renewable energy into the national grid.

In this blog, we explore the biggest upcoming battery storage projects in Saudi Arabia in 2025, according to the installed capacity.

List of Top 5 Upcoming Battery Energy Storage System Projects in Saudi Arabia 2025 (according to installed capacity)

BYD – Saudi Electricity Company BESS Deployment

The BYD – Saudi Electricity Company BESS (battery energy storage system) Deployment is the largest upcoming BESS project in Saudi Arabia and also the world’s largest grid-scale battery deployment, totaling 2.5 GW / 12.5 GWh of capacity. The project will be distributed evenly across five strategic sites, including Riyadh, Qaisumah, Dawadmi, Jouf, and Rabigh, each with 500 MW / 2,500 MWh of installed capacity.

BYD will deliver its MC Cube-T energy storage system, which integrates Cell-to-System (CTS) technology to achieve higher efficiency and space utilization. The company’s scope includes system design, equipment supply, installation supervision, commissioning, and long-term maintenance. Each installation will be capable of delivering black start support, frequency regulation, voltage support, and peak shaving services.

HiTHIUM Tabuk BESS

The Saudi Electricity Company is building two major battery energy storage projects in northern Saudi Arabia with Hithium, totaling 4 GWh of capacity. The installations will be located in Tabuk and Hail provinces and will rank among the largest BESS deployments in the Middle East.

Hithium will supply its advanced ∞Cell 1175Ah battery technology, incorporated into 6.25 MWh Desert Eagle containerized systems. These units are engineered for long-duration storage and optimized for the extreme climate conditions of Saudi Arabia.

Multi-layer insulation reduces internal temperatures by 8 to 10°C, ensuring reliable operation across a range from -30°C to 60°C. Sealed components and automated dust alerts further minimize maintenance needs, while critical parts are rated for 40,000 hours of continuous operation.

The projects will deliver essential grid services such as load shifting, black-start capability, frequency regulation, and voltage support. Hithium will manage design, supply, supervision, and long-term system maintenance, while Alfanar Projects will oversee the construction phase. Both sites are expected to be commissioned in 2026.

Al-Muwaih BESS ISP

The Al-Muwaih Battery Energy Storage System (BESS) is a 500 MW / 2,000 MWh project being developed in Saudi Arabia’s Makkah Province under a build-own-operate (BOO) framework. Located about 180 kilometers northeast of Taif, the project is designed to enhance flexibility and reliability within the national grid.

The system will primarily perform load shifting, enabling more efficient use of power generation assets by charging during periods of low demand and discharging when demand peaks. In addition, the BESS will support critical grid services such as black-start capability, frequency regulation, and voltage support. Operators can allocate portions of the system’s total capacity at its point of interconnection, allowing targeted responses to network requirements.

By replacing the need for part-load operation of existing power plants, the project will improve overall efficiency and reduce fuel dependency. It also plays a key role in maintaining voltage and frequency stability across the distribution network.

Haden Battery Energy Storage System (BESS) – ISP Phase 1

The Haden Battery Energy Storage System (BESS) is part of the first phase of Saudi Arabia’s Independent Storage Provider (ISP) program, overseen by the Saudi Power Procurement Company (SPPC). The project will deliver 500 MW of capacity with a four-hour duration, equal to 2,000 MWh of energy storage.

Developed under a build-own-operate (BOO) framework, the project will be procured through a competitive tendering process. Prequalified firms, both local and international, will bid to develop the scheme, with the successful bidder holding 100% equity in a special purpose vehicle (SPV).

Once operational, the Haden BESS will enter into a 15-year storage services agreement with SPPC. Its role will be to provide critical grid support services, including load shifting, frequency regulation, black-start capability, and voltage stability, by integrating this large-scale storage resource into the Makkah grid.

Al-Kahafa Battery Energy Storage System (BESS) – ISP Phase 1

The Al-Kahafa Battery Energy Storage System (BESS) is one of four large-scale energy storage projects tendered under the first phase of Saudi Arabia’s Independent Storage Provider (ISP) program. The facility will provide 500 MW of capacity with a four-hour duration, equal to 2,000 MWh of storage.

The project will be awarded through SPPC’s competitive tender. Prequalified bidders include leading global players such as Masdar, ACWA Power, EDF, TotalEnergies, Samsung, and Jinko Power, alongside Chinese, Korean, and Japanese developers.

Once operational, Al-Kahafa BESS will deliver critical grid services such as load shifting, black-start capability, frequency regulation, and voltage support. Its integration into the northern grid will reduce reliance on fossil generation while enabling higher renewable penetration.

Conclusion

From the record-breaking 2.5 GW / 10 GWh BYD–SEC Phase 3 project to innovative long-duration systems like HiTHIUM’s 1175Ah-based deployments, Saudi Arabia is redefining the role of energy storage in national power systems. The sector is further boosted by some of the biggest projects, such as the Red Sea microgrid, which integrates over 1.3 GWh of storage to power urban and tourism development with clean energy.

Backed by competitive tenders from SPPC and SEC, and a cost target of less than USD 75/kWh, Saudi Arabia’s BESS expansion is not only central to its renewable integration goals but also reshaping the global storage market’s economics and scale.
