BYD and Saudi Electricity Company Sign Record-Breaking 12.5GWh Energy Storage Deal

BYD Energy Storage and Saudi Electricity Company (SEC) have signed the world’s largest grid-scale battery energy storage contract, totaling 12.5GWh. This agreement builds on their prior collaboration, which included a 2.6GWh project, bringing their combined energy storage capacity to 15.1GWh.

The initiative aligns with Saudi Arabia’s Vision 2030, which aims to integrate 50% renewable energy into the national grid. The energy storage systems will be deployed across five sites to enhance grid stability and accommodate fluctuations from renewable power sources.

BYD will supply its MC Cube-T ESS, incorporating its CTS (Cell-to-System) super-integrated technology, which features a Vcts index exceeding 33%—setting a global benchmark for efficiency. BYD Energy Storage stated, “This project will redefine the role of electrochemical energy storage solutions in the global energy transition.”

Since introducing its first battery energy storage system 17 years ago, BYD has delivered 75GWh of storage solutions across 350 projects in more than 110 countries. This agreement further reinforces BYD’s leadership in large-scale renewable energy storage.

Looking forward, BYD plans to expand investments in R&D and strengthen global partnerships to drive innovation in clean energy solutions.
