BYD Energy Storage Signs World’s Largest 12.5 GWh Grid-Scale Battery Project in Saudi Arabia

BYD Energy Storage, a global leader in energy storage solutions, has officially signed contracts with the Saudi Electricity Company for the world’s largest grid-scale battery storage project with a capacity of 12.5 GWh. When combined with the previously delivered 2.6 GWh project, the total partnership now amounts to an extraordinary 15.1 GWh of energy storage capacity.

This milestone marks a new global record and demonstrates BYD’s leadership in delivering ultra-large-scale energy storage systems (BESS) to support energy transition and grid stability worldwide.

Powering Saudi Arabia’s Vision 2030

Saudi Arabia has set ambitious targets to achieve a 50% renewable energy mix by 2030 as part of its Vision 2030 strategy. The new BYD projects will be installed across five sites, integrating directly into the national transmission network.

These storage systems will help the country:

• Stabilize power supply amid growing renewable energy capacity

• Meet peak energy demand reliably

• Enhance national energy security with flexible, efficient infrastructure

By deploying BYD’s next-generation MC Cube-T ESS systems, Saudi Electricity Company ensures long-term scalability and performance.

Leading Technology: CTS Super-Integration

The new systems feature BYD’s pioneering Cell-to-System (CTS) technology, with a Vcts index exceeding 33%. This means higher density, more compact layouts, and improved efficiency.

With BYD’s AI-driven thermal management, robust safety design, and modular architecture, the 12.5 GWh of storage will play a vital role in balancing Saudi Arabia’s growing renewable grid.

BYD’s Track Record of Excellence

For over 17 years, BYD has been at the forefront of LFP-based battery energy storage systems (BESS). To date, it has delivered more than 75 GWh of storage capacity across 350 projects in 110+ countries and regions.

This unmatched global experience, combined with strong delivery capabilities and after-sales service, has earned BYD widespread recognition and trust from partners worldwide.

Redefining Energy Storage

This historic signing is more than just a project milestone—it redefines the role of electrochemical energy storage in modern energy systems. From the generation side to the utility and consumption sides, BYD is shaping a cleaner, more sustainable future with its “all-scenarios, all-value, all-ecology” product philosophy.

Solar&Solar’s Perspective

At Solar&Solar, we view BYD’s achievement as a transformative step for the global energy storage industry. Delivering more than 15 GWh of capacity in Saudi Arabia proves that large-scale BESS can stabilize grids, accelerate renewable adoption, and bring nations closer to carbon neutrality.

As storage becomes the backbone of renewable integration, BYD is leading the way in proving what’s possible.
