Saudi Power Procurement Company has signed four battery energy storage agreements worth more than 4.35 billion riyals, or about 1.16 billion dollars, as the kingdom works towards a target of roughly half its electricity generation coming from renewable sources by 2030. The agreements were signed in Riyadh and reported on 21 August 2026.
The four projects carry a combined capacity of 2,000 megawatts with a four hour duration, giving 8,000 megawatt hours of storage, and are structured on a build own operate basis. A consortium of Saudi Energy, ACWA Power and Al Sharif Contracting and Commercial Development Company won three facilities of 500 megawatts and four hours each. Engie, together with Haji Abdullah Alireza and Company, won the project at Qassim. Prince Abdulaziz bin Salman, the minister of energy, chairs the procurement company.
The four hour duration is the technically important figure. Storage sized for four hours is intended to shift solar generation from the middle of the day into the evening peak, rather than to provide the short bursts of output that support grid stability, which is a different and cheaper product. In a market where air conditioning drives a pronounced evening load and solar output collapses at sunset, that is the shape of storage the system actually needs if renewable generation is to displace gas rather than simply sit alongside it.
The build own operate structure matters as well. Under that model the developer carries construction and operating risk and is paid over the life of the contract, which keeps the capital off the buyer balance sheet and transfers performance risk to parties with an incentive to manage it. It is the same structure the kingdom has used to bring down the cost of its solar procurement, and applying it to storage suggests an intention to run the same competitive tension on price.
Awarding three of the four facilities to a single consortium concentrates delivery risk, though it also allows standardisation across sites, which usually lowers cost and shortens build times. The genuine test will be whether these first projects establish a repeatable price for storage in the kingdom, because a generation mix of roughly half renewables will require considerably more than 8,000 megawatt hours.
