BYD Energy Storage has signed contracts with Saudi Electricity Company (SEC) for grid-scale battery energy storage projects totalling 12.5GWh, marking the world’s largest deployment of its kind at the time.
With the addition of a previously delivered 2.6GWh project, the total collaboration between BYD and SEC now reaches 15.1GWh.
This agreement represents a significant step in Saudi Arabia’s efforts to advance its renewable energy sector and aligns with the country’s Vision 2030 objectives. As part of its strategy to transition to a more sustainable energy mix, Saudi Arabia aims for 50% of its electricity generation to come from renewable sources by 2030. SEC has been actively developing initiatives to integrate renewable energy into the national grid to enhance energy security and efficiency.
The battery energy storage system (BESS) equipment will be installed at five locations across the country. BYD Energy Storage will provide its latest MC Cube-T ESS, incorporating its proprietary Cell-to-System (CTS) technology, which achieves a cell-to-system volume ratio (Vcts) of over 33%. These storage systems will be integrated into Saudi Arabia’s power transmission network to help manage grid fluctuations caused by increased renewable energy adoption, stabilise electricity supply, and meet peak demand requirements.
BYD introduced its first pilot BESS project 17 years ago, exploring the potential of lithium iron phosphate (LFP)-based battery storage for grid applications. Since then, the company has delivered more than 75GWh of BESS equipment to over 350 projects in 110 countries and regions. Its energy storage portfolio spans applications across generation, utility, and consumption sectors, supported by an integrated supply chain that includes research, development, manufacturing, sales, and service.
The latest collaboration is expected to strengthen the role of electrochemical energy storage in the global transition to cleaner energy. BYD Energy Storage has stated that it will continue to invest in research and development while working with international partners to advance energy storage technologies and support the broader transition to sustainable power systems.
