BYD Energy Storage and Saudi Electricity Co. have signed an agreement to develop a 12.5-gigawatt-hour (GWh) battery energy storage system (BESS)—the largest grid-scale energy storage project in history. This milestone expands their total collaboration to 15.1 GWh, including a previously completed 2.6 GWh project.

Boosting Saudi Arabia’s Renewable Energy Goals

This project supports Saudi Arabia’s Vision 2030, which targets a 50% renewable energy mix. By enhancing grid stability and energy security, the initiative ensures a reliable electricity supply amid the country’s transition to renewable power sources.

The BESS units will be deployed across five locations in Saudi Arabia. BYD will supply its MC Cube-T energy storage system, which leverages Cell-to-System (CTS) technology to optimize energy density and efficiency.

Key Benefits of the Project:

Balances renewable energy fluctuations
Enhances grid stability & peak demand management
Accelerates Saudi’s clean energy transformation

“With this cooperation, Saudi Electricity Company is demonstrating its commitment to leveraging advanced energy storage technologies to improve efficiency and accelerate the country’s renewable energy transition,” BYD stated.

BYD’s Global Energy Storage Leadership

BYD has deployed over 75 GWh of BESS equipment across 110 countries in 350+ projects.
17+ years in the energy storage industry, investing heavily in R&D and innovation.
A diversified product portfolio, covering generation, utility, and consumption applications.

Future Expansion & Innovation

As battery storage becomes a cornerstone of the global energy transition, BYD remains committed to expanding its technological investments and business development initiatives.

This landmark deal cements Saudi Arabia’s position as a leader in renewable energy integration, while reinforcing BYD’s dominance in grid-scale energy storage solutions.
