Acwa signs agreements for 6,000 MWh of battery storage in Saudi Arabia

Acwa has signed three Storage Services Agreements with the Saudi Power Procurement Company for battery energy storage plants at Haden, Muwayh and AlKahfah, in the presence of HRH Prince Abdulaziz bin Salman bin Abdulaziz, Minister of Energy, at a ceremony held at the Ministry of Energy in Riyadh on 20 August 2026.

This represents one of the largest BESS procurements globally and further establishes Acwa’s leadership in clean energy and energy storage technologies. The projects further expand Acwa’s rapidly growing BESS portfolio, building on its experience in developing and delivering large-scale storage solutions across its key markets. Energy storage is becoming an increasingly important part of Acwa’s portfolio, complementing its large-scale renewable energy platform and enabling greater integration of solar and wind into power systems. 

Each plant is rated at 500 MW with 2,000 MWh of storage capacity and will supply power under a 15-year agreement. Haden and Muwayh are located in the western region of the Kingdom, while AlKahfah is located in the north. At full output, each facility will provide four hours of battery storage.

Omar Al Hassan, CEO – Saudi Arabia at Acwa, said: “Energy storage systems has become an essential part of how the Kingdom is developing its power system, rather than simply an addition that comes after renewable energy projects are in place. These plants will hold energy generated through the day and release it when demand reaches its peak. We are delivering them in close step with the Ministry of Energy and the Saudi Power Procurement Company.”

The tender was run by SPPC, which the Ministry of Energy oversees as the Kingdom’s principal buyer of electricity. Pricing storage as a service in its own right gives Saudi Arabia a route to market it can repeat for later tranches, in line with the Vision 2030 aim of diversifying the energy mix.

Storage has featured in Acwa’s project designs for several years now, most visibly at Tashkent Riverside in Uzbekistan, where 770 MWh of batteries is paired with 200 MW of solar. The Red Sea Project on the Saudi coast runs on 1,227 MWh and supplies a destination-scale development with no grid connection at all.

Across the Kingdom, Acwa holds 41 assets spanning solar, wind, gas, desalination and green hydrogen, and it is mandated by the Public Investment Fund to develop around 70 percent of Saudi Arabia’s renewables pipeline.
