SEC, under the supervision of Ministry of Energy, has commenced Phase 2 of BESS development, with a total investment exceeding SAR6.73 billion. This phase, with a combined storage capacity of 2.5 GW, comprises five battery storage sites located in Riyadh, Al-Qaisumah, Al-Jawf, Al-Dawadmi, and Rabigh.
The initiative forms part of NREP, aiming to integrate approximately 50 per cent renewable energy into the country’s electricity mix by 2030. Contracts for this phase have been awarded to Chinese group BYD Auto Company and Saudi utility major Alfanar Projects, who will deliver 500 MW/2,000 MWh storage systems at each of the five locations. The BESS systems are expected to enhance the reserve margin across operational areas, improve grid reliability, increase flexibility in demand response, and optimise energy distribution efficiency. The design allows the rapid transition from standby to operational mode, significantly strengthening power system resilience and reducing operational costs. The implementation of this phase will ensure full integration with the national grid while complying with regulatory standards and safety protocols.
