BYD Energy Storage has signed a deal with Saudi Electricity Co. to develop 12.5 gigawatt-hours of battery energy storage systems, marking the world’s largest grid-scale energy storage project to date, the Chinese firm said on Monday.
The agreement expands the companies’ collaboration to 15.1 GWh, including a previously delivered 2.6 GWh project.
BYD said in a statement that the initiative aligns with Saudi Arabia’s Vision 2030 goal of achieving a 50 percent renewable energy mix and aims to enhance grid stability and energy security.
Enhancing Grid Stability and Energy Security
The BESS equipment will be installed at five sites across Saudi Arabia. BYD will supply its MC Cube-T energy storage system, which features its proprietary Cell-to-System technology, designed to maximize energy density and efficiency.
The company said the system will be integrated into the country’s power transmission network to balance the increasing share of renewable energy, stabilize electricity supply and manage peak demand.
“With this cooperation, Saudi Electricity Company is demonstrating its commitment to leveraging advanced energy storage technologies to improve energy efficiency and accelerate the country’s renewable energy transition,” BYD stated.
BYD, a global leader in energy storage solutions, has delivered over 75 GWh of BESS equipment to more than 350 projects in 110 countries.
Expanding footprint
Over its 17-year history in the energy storage sector, the company has invested heavily in research and development, developing a product portfolio that spans generation, utility and consumption applications.
The deal reflects the growing role of large-scale battery storage in global energy systems as countries shift toward renewable energy sources.
BYD said it will continue to expand its investments in technology innovation and business development to support the global energy transition.
