The UAE's renewable energy sector — anchored by giga-scale solar developments such as the Mohammed bin Rashid Al Maktoum Solar Park, alongside a growing pipeline of solar, waste-to-energy and green hydrogen projects across Abu Dhabi and the wider GCC — has matured from a policy ambition into one of the region's most active sources of complex construction and commercial arbitration. As these projects move from construction into long-term operation, disputes are increasingly turning on specialised quantum and technical expert evidence.
Where Renewable Energy Disputes Typically Arise:
Disputes on UAE and GCC renewable projects commonly cluster around:
• EPC delay and performance disputes, particularly around grid connection delays, a recurring bottleneck across GCC renewable programmes • Performance guarantee and liquidated damages disputes, where actual energy yield falls short of guaranteed performance ratios for solar PV or CSP assets • Equipment defect and warranty claims, especially concerning panel degradation, inverter failure, or tracker system faults • Interconnection and curtailment disputes, where grid operator constraints affect actual versus contracted output • Structural and civil works disputes, particularly foundation and mounting system performance in the UAE's high-wind, high-temperature desert environment
The Distinct Role of Quantum Experts in Energy Disputes:
Quantum experts in renewable energy disputes face valuation challenges quite different from conventional building disputes:
• Loss of revenue calculations require detailed modelling of expected energy yield against actual or projected output, typically drawing on P50/P90 energy yield assessments and long-term meteorological datasets specific to the project site • Availability and performance ratio disputes require experts to reconcile SCADA and metering data against contractual performance guarantees, often across large datasets spanning years of operation • Discount rate and long-term revenue modelling becomes central where disputes concern the capitalised value of lost future generation under power purchase agreements, frequently structured with UAE and Abu Dhabi government-related offtakers
The Distinct Role of Technical Experts:
Technical experts — typically electrical, mechanical or structural engineers with specific renewable energy sector experience — are engaged to address:
• Root cause analysis of equipment underperformance or failure, distinguishing design defects, manufacturing defects, and installation or commissioning errors • Compliance with IEC and relevant international standards applicable to solar PV, wind, and battery storage systems as adopted in UAE project specifications • Environmental factors specific to the Gulf, including dust accumulation (soiling losses), extreme heat derating, and sand abrasion effects on tracking and mounting systems
Why These Disputes Demand Sector-Specific Expertise:
Renewable energy disputes differ from conventional building and infrastructure disputes in one crucial respect: the underlying asset generates a measurable, ongoing revenue stream, meaning quantum experts must combine construction claims methodology with energy yield modelling more commonly associated with project finance and technical due diligence work. Experts without genuine renewable sector experience often struggle to engage credibly with performance data, SCADA outputs, and yield assessment methodologies that specialist tribunals and counsel increasingly expect to see addressed rigorously.
Forum Considerations:
Renewable energy disputes involving UAE and GCC government-related offtakers are frequently resolved through DIAC or ICC arbitration seated in the DIFC or ADGM, reflecting the international financing structures typically underpinning these projects. This generally means party-appointed expert evidence prepared in line with the IBA Rules, with increasing tribunal appetite for early expert conferral and, in appropriate cases, concurrent evidence sessions to test competing yield and performance methodologies directly.
Looking Ahead:
As the UAE and wider GCC accelerate investment in solar, green hydrogen and battery storage infrastructure, the volume and complexity of associated disputes is expected to grow substantially. Parties involved in developing, financing, constructing or operating these assets should ensure their expert witness teams combine construction and quantum expertise with genuine, current renewable energy sector knowledge — an increasingly specialised requirement that generalist construction experts are not always equipped to meet.
