On April 27, the resonant sound of ship horns pierced the sky as BYD Energy Storage successfully loaded 120 MC Cube-T energy storage system cabinets onto vessels at the Beibu Gulf Port in Guangxi. As the vanguard of the 12.5GWh project—the world’s largest grid-side energy storage initiative—these systems have embarked on a transoceanic journey to Saudi Arabia, supporting the nation’s energy transition.
Following the landmark agreement with Saudi Electricity Company (SEC) in early 2025 for the world's largest 12.5GWh grid-side energy storage project, BYD Energy Storage has launched its delivery campaign with unprecedented momentum. A total of 2,364 modular MC Cube units are now being transported to Saudi Arabia in highly efficient, well-coordinated batches, setting a new industry record for deployment speed and redefining global execution standards for utility-scale storage projects.
Vertical Integration & Full-Stack Innovation: A Complete Lifecycle Management System
The successful execution of global utility-scale energy storage projects stems from BYD Energy Storage's forward-looking strategic positioning. With end-to-end in-house R&D spanning core competencies—from material development, manufacturing processes, and intelligent battery cell design to BMS, EMS, and the modular MC Cube system—the company maintains full industrial chain innovation and deep vertical integration. From customized energy storage solutions and logistics to O&M and after-sales services, BYD has established a mature, standardized, and process-driven full lifecycle management system. Faced with Saudi Arabia's record-breaking 12.5GWh project, BYD Energy Storage can rapidly coordinate production, shipment, and transportation through its robust resource allocation and high-efficiency execution capabilities. This ensures professional project delivery and operational management, providing unwavering support for the project's timely advancement through proven technical expertise.
Integrated Innovation & Mutual Empowerment, Enhancing Full Lifecycle Economics
BYD Energy Storage and its automotive division mutually empower each other in scaled production and supply chains, sharing ecosystem resources. Leveraging large-scale manufacturing capabilities, this synergy supports rapid delivery of utility-scale energy storage projects worldwide, including in Saudi Arabia, Europe, and Latin America. The MC Cube-T energy storage system adopts BYD Energy Storage’s globally pioneering CTS (Cell-to-System) ultra-integrated technology, achieving a Vcts (cell-to-system volume ratio) exceeding 33%. This significantly increases the proportion of core equipment in energy storage stations, improving full lifecycle cost efficiency. Featuring a modular, compartmentalized design, the system offers multiple advantages: easy deployment, effortless transportation, simplified installation, seamless capacity expansion, convenient maintenance. These innovations reduce logistical complexities during transit and enable rapid on-site commissioning, further streamlining construction processes to ensure on-schedule project deployment.
Global Presence & Sustained Dedication, Empowering the Worldwide Energy Transition
For 17 years, BYD Energy Storage has been deeply rooted in the energy storage sector, expanding globally with unwavering commitment and accumulating profound expertise. By the end of 2024, BYD Energy Storage has established a comprehensive worldwide network encompassing sales, delivery, operations, and after-sales services. With over 75GWh of commercial operation experience and more than 360 successfully delivered energy storage projects, its solutions have been deployed across 110+ countries and regions.
