Saudi Arabia's Saudi Power Procurement Company has qualified 27 developers to bid on its second round of large-scale battery energy storage system tenders, one of the biggest storage procurement exercises attempted anywhere in the region.
The qualified list, published earlier this week, includes a mix of Saudi utility developers, established Gulf renewable-energy players and international storage specialists. Bidders will now compete on a series of specific project sites for capacity that officials have indicated runs to several gigawatt-hours in aggregate, dwarfing the pilot-scale rounds that came before.
Why storage now
Saudi Arabia's renewable-energy pipeline has grown quickly over the past three years, with utility-scale solar plants at Sudair, Al Shuaibah and other locations now feeding meaningful volumes of intermittent power into the grid. Battery storage is the natural counterpart, absorbing solar output during daylight and dispatching it back into the network during evening peaks. The absence of large-scale storage has been a widely flagged bottleneck for the kingdom's decarbonisation targets and for its ability to run existing renewables at their full contract load factors.
The current tender is structured around long-duration storage projects with multi-hour discharge windows, rather than the short-duration frequency-response systems that dominated the first generation of grid-scale storage globally. That reflects the specific shape of the Saudi load curve, where evening cooling loads run long and hard through the summer.
What bidders are competing on
Bidders are expected to compete primarily on levelised cost of storage, financing terms and local content commitments. Saudi Arabia's In-Kingdom Total Value Add procurement framework, known as IKTVA, applies to the tender and gives weight to bidders who commit to using Saudi manufactured components, Saudi engineering resources and Saudi operations and maintenance capacity.
Financing has been a live topic for the sector. Battery equipment prices have fallen sharply over the past 24 months, but interest rates and shipping costs have offset part of that gain. The Saudi tender permits a mix of local and international financing structures, and several qualified bidders are expected to arrange sharia-compliant tranches through Gulf banks.
Regional context
The tender comes as other Gulf states move on similar procurement. The UAE has announced early-stage tenders for storage additions at existing solar sites, and Oman has flagged battery capacity as part of its power master plan. Together with Saudi Arabia's push, the region is on track to build one of the fastest-growing utility-scale storage markets outside of China and the United States.
Timeline
Bids from the 27 qualified firms are expected over the coming weeks, with contract awards likely later in the year. Officials have indicated that the pace of subsequent rounds will depend on how quickly the first tranche of projects reaches financial close and construction, and that a third qualifying round is already being prepared to keep the pipeline moving.
