The project serves the power grids of five major power regions across Saudi Arabia: Riyadh, Rabigh, Dawadmi, Jouf and Qassim. As the world’s largest grid-side grid-forming energy storage cluster, it is equipped with more than 2,000 PCS units and integrates core grid-forming functions including power regulation, primary frequency control, dynamic voltage regulation, black start and weak/strong grid adaptability. The project will effectively enhance the Saudi power grid’s regulation capabilities and renewable energy integration capacity, alleviate local power supply shortages, and ensure the stable operation of the grid. It also fully aligns with Saudi Arabia’s energy transformation strategy, strongly underpins the delivery of Saudi Vision 2030, and facilitates the development of a new-type power system in the country.

As a global pioneer in grid-forming energy storage technology, NR Electric has put forward the concept of building ideal synchronous power sources via energy storage, and launched the NR-ISGrid grid-forming solution. The product portfolio covers grid-forming energy storage, grid-forming VSC-HVDC, grid-forming STATCOM and static synchronous condensers, leading the industry with cutting-edge core technologies. The successful grid connection of Saudi SEC’s 2.5 GW energy storage project represents another milestone for NR Electric in leveraging grid-forming energy storage to drive the transition from traditional power systems to new-type power systems. Upholding its corporate mission of "Creating Value, Serving Society", NR Electric will continue to contribute expertise to the safe and stable operation of power grids and the development of new-type power systems worldwide.
