The tender, run by SPPC’s Principal Buyer arm, is the second of its kind in Saudi Arabia. Launched in April, it is seeking companies to deploy six large-scale battery energy storage system (BESS) projects:
- The 500MW/2,000MWh Samha BESS ISP, Site Location: Qassim province
- The 500MW/2,000MWh Al-Leeth BESS ISP, Site location: Makkah province
- The 500MW/2,000MWh Al-Henakiyah BESS ISP, Site location: Madinah province
- The 500MW/2,000MWh Khulis BESS ISP, Site location: Makkah province
- The 500MW/2,000MWh Sadawi BESS ISP, Site location: Eastern province
- The 500MW/2,000MWh Ashyrah BESS ISP, Site location: Makkah province
Qualified bidders were revealed for the first tender, totalling 2GW/8GWh across four projects, in January 2025 though no update has been issued since.
Energy-Storage.news published an ESN Premium feature on the Saudi and UAE markets back in January. Projects covered in that piece, combined with this new tender, mean there is some 77GWh of large-scale BESS under development, procurement or construction in the two countries combined.

Sentinel — Human

Confidence

The text reads like a direct compilation of factual data drawn from an official release or established news wire reporting rather than synthetic narrative generation.

Signals Detected
low severity: Moderate sentence length variance; mostly direct, data-driven statements typical of wire reporting.
low severity: High coherence within the factual presentation; lacks flowery language but is logically structured around specific tender details.
low severity: No obvious repetition of argumentative structures or vague attribution typical of generic AI synthesis; facts are cited directly.
low severity: Claims are tied to specific corporate names, tender numbers, and locations, making the risk low unless all source data is systematically flawed.
Human Indicators
The structure mirrors standard financial/energy reporting (focus on qualified bidders, capacity, locations).
Presence of highly specific entity names (SPPC, ACWA Power, Masdar, Envision Energy) suggests sourcing from specific industry reports.
Inclusion of promotional material that is clearly separate from the main analytical text (the Premium subscription pitch).
