Saudi SASO Enforces SASO IEC 62933-5-2:2026 Mandatory Standard, Requiring Local High-Temperature Cycle Life Testing for Imported Energy Storage Systems

Introduction

On March 23, 2026, the Saudi Standards, Metrology and Quality Organization (SASO) implemented the mandatory SASO IEC 62933-5-2:2026 standard, introducing new extreme high-temperature durability testing requirements for imported energy storage systems. This development is particularly relevant for energy storage manufacturers, exporters, and project developers targeting the Saudi market. The new regulation is expected to impact certification timelines, supply chains, and competitive dynamics in one of the Middle East's fastest-growing energy storage markets.

Event Overview

The SASO IEC 62933-5-2:2026 standard mandates that all imported energy storage systems undergo localized high-temperature cycle life testing within Saudi Arabia. Major Chinese manufacturers like Sungrow and BYD have already established joint testing centers in Jeddah to facilitate compliance. For companies without local testing facilities, the certification process is reportedly extending to an average of 14 weeks, affecting participation in key projects such as the NEOM City Phase II energy storage tender.

Impact on Specific Industry Segments

Energy Storage System Manufacturers

The new requirement creates immediate operational challenges for manufacturers without existing Saudi testing capabilities. Companies now face either establishing local testing partnerships (like the Sungrow-BYD model) or accepting extended certification timelines that could delay market entry.

Project Developers and EPC Contractors

Developers working on Saudi energy projects, particularly those with strict timelines like NEOM, may experience procurement delays. The 14-week certification extension could disrupt project schedules and necessitate earlier procurement planning.

Testing and Certification Service Providers

The regulation presents business opportunities for international testing organizations to partner with Saudi entities. Current testing capacity in Saudi Arabia may struggle to meet sudden demand increases, creating potential bottlenecks.

Key Considerations and Recommended Actions

Prioritize Local Testing Partnerships

Manufacturers should evaluate establishing local testing collaborations through Saudi partners or consider shared testing facilities to reduce certification timelines. The Sungrow-BYD joint center model demonstrates one viable approach.

Adjust Project Timelines and Procurement Strategies

Project developers should factor in extended lead times for energy storage components in Saudi projects. Earlier engagement with certified suppliers and buffer periods in project schedules may become necessary.

Monitor Implementation Details

Companies should track how SASO implements the testing requirements in practice, including potential exemptions, testing capacity expansion, and possible adjustments to the certification process.

Evaluate Cost Implications

The new testing requirements may increase compliance costs. Manufacturers should assess how to absorb or pass through these costs while remaining competitive in the Saudi market.

Editor's Perspective / Industry Observation

From an industry perspective, this regulation signals Saudi Arabia's focus on ensuring energy storage system reliability in extreme climate conditions. While creating short-term challenges, it reflects the market's maturation and may drive long-term quality improvements. The immediate bottleneck appears to be testing capacity, suggesting potential opportunities for international testing providers to enter the Saudi market through partnerships.

This development should be viewed as part of Saudi Arabia's broader energy transition strategy rather than an isolated regulatory change. The emphasis on local testing also aligns with Saudi localization goals under Vision 2030.

Conclusion

The SASO IEC 62933-5-2:2026 implementation represents a significant regulatory shift for energy storage systems in Saudi Arabia, with immediate impacts on market access timelines and competitive dynamics. While presenting challenges, it also offers opportunities for companies that can quickly adapt through local partnerships and strategic planning. The industry should monitor how testing capacity develops and whether SASO adjusts implementation details based on initial experience.
