Saudi Arabia has commissioned the world’s largest grid-side grid-forming battery storage cluster, signalling a major step in its Vision 2030 energy diversification plans and reinforcing the country’s move towards a more resilient, renewable-heavy power system.
Saudi Arabia’s power system has reached a new milestone with the activation of what Saudi Energy says is the world’s largest grid-side grid-forming battery storage cluster, with 2.5 gigawatts of installed capacity spread across five sites. The systems, supplied by BYD Energy Storage, have completed grid-connected charging and discharging tests and are now in operation in Riyadh, Rabigh, Dawadmi, Al Jouf and Qassim.
The project is being presented as a strategic step in the Kingdom’s wider energy overhaul, with officials tying it to Vision 2030’s push to diversify the energy mix and speed up deployment of low-carbon infrastructure. Vision 2030, the government’s long-term economic blueprint, places energy diversification and investment in advanced infrastructure at the centre of Saudi Arabia’s industrial transformation.
For industrial and power-sector stakeholders, the significance of the project goes beyond its scale. Grid-forming battery systems are designed to provide stability services that conventional storage cannot always deliver, including stronger frequency support, better integration of renewable generation and improved resilience in networks facing local constraints. In a market preparing for far higher shares of solar and wind, those capabilities are becoming increasingly important.
Saudi Energy, formerly Saudi Electricity Company, said the storage cluster is part of its Phase III Energy Storage Programme. The company has linked the scheme to the broader effort to reinforce electricity supply across the national grid while easing pressure in fast-growing demand centres. According to the project announcement, the system incorporates more than 2,000 power conversion units, underlining the engineering complexity of the build.
The project also highlights the speed at which Saudi Arabia is scaling battery storage. In February 2025, BYD Energy Storage said it had signed contracts with Saudi Electricity Company for grid-scale storage projects totalling 12.5 GWh, which it described as the world’s largest such package. Separately, Energy-Storage.news reported in December 2025 that Saudi Arabia had connected a 7.8 GWh battery project across three sites in the south-west of the country, showing that the Kingdom’s storage build-out is progressing in parallel across multiple regions and technologies.
Alfanar Projects acted as the engineering, procurement and construction contractor for the newly activated cluster and said it delivered the five schemes in record time. That matters for a country seeking to accelerate grid reinforcement while keeping pace with large renewable additions and rising electricity demand from industry, cities and new economic zones.
For suppliers, investors and industrial decarbonisation specialists, the project is another signal that Saudi Arabia is moving storage from pilot status to system-critical infrastructure. The emphasis is no longer only on capacity in gigawatt-hours, but on operational performance, grid services and the ability to support a more flexible, renewable-heavy power system.
