Solar-Plus-Storage Technical Advisory & Engineering Services
Bureau Veritas delivers independent technical, commercial, and risk advisory services supporting the complete lifecycle of utility-scale solar and solar-plus-storage projects—from development and financing through construction, commissioning, and long-term operations.
With rapidly increasing electricity demand driven by data centers, electrification, and grid modernization, utility-scale solar-plus-storage systems have become critical infrastructure for today’s power systems. By combining renewable generation with flexible energy storage, these projects enhance grid reliability, improve dispatchability, and support the integration of large, energy-intensive loads while advancing decarbonization goals. However, the growing scale and complexity of hybrid projects introduce new technical, commercial, and operational risks that must be carefully managed.
Bureau Veritas combines global scale with hands-on technical expertise to deliver independent advisory services that are both rigorous and responsive. Through our international network of technical centers and specialized experts, we provide rapid, nimble support tailored to the specific needs of each solar and energy storage project. Our teams operate as an extension of our clients’ technical organizations, offering full availability, fast turnaround, and seamless coordination across disciplines to support confident decision-making at every stage of development, financing, construction, and operations.
Comprehensive Solar-Plus-Storage Advisory Services
Clients engage our services for more than independent verification—they gain immediate access to a global platform of renewable energy specialists. Our integrated service delivery model enables rapid deployment of experienced engineers and subject-matter experts across geographies, providing consistent, bankable advisory services while maintaining flexibility for evolving project timelines, transaction schedules, and technical challenges.
Technical Due Diligence & Transaction Support
Comprehensive technical due diligence services support M&A transactions, portfolio acquisitions, and project financings involving solar, battery energy storage, and hybrid assets. Our assessments are designed to support valuation models by identifying technical, commercial, and operational risks that may affect capital expenditure, operating costs, energy production, and long-term performance. We translate technical findings into clear conclusions and mitigation actions, enabling investors, lenders, and developers to structure transactions with confidence and allocate risk appropriately.
Owner’s Engineer (OE)
Owner’s Engineer services are delivered through globally aligned technical teams with deep local market knowledge. Leveraging our international technical centers, we provide timely design reviews and commissioning support with the agility required to meet fast-paced project and financing schedules. Our experts work side-by-side with project stakeholders, acting as an extension of the owner's or lender's technical team to proactively identify risks, resolve issues, and support successful project delivery.
Energy Storage & Hybrid Systems Advisory
Energy storage and hybrid projects require specialized expertise and close coordination across engineering disciplines. Direct access to global battery, power systems, safety, and controls specialists enables rapid deployment to support project-specific needs. Our advisory services help clients navigate technology selection, safety and code compliance, system integration, and lifecycle performance considerations, delivering practical solutions that reflect both global best practices and local regulatory requirements.
Safe Harbor, Tax Credit & U.S. Regulatory Compliance Advisory
Independent verification and advisory services support compliance with U.S. federal, state, and local regulatory requirements, including Safe Harbor qualification and tax credit eligibility. Our experts support Production Tax Credit (PTC) and Investment Tax Credit (ITC) verification, domestic content assessments, and documentation reviews aligned with IRS and financing requirements. By combining technical, contractual, and schedule analysis, we help clients demonstrate compliance, reduce tax credit risk, and protect project value throughout development, construction, and commissioning.
Solar Energy Resource Assessments (SERA) & Operational Backcast Energy Assessments (OBEA)
Independent Solar Energy Resource Assessments (SERAs) and Operational Backcast Energy Assessments (OBEAs) are tailored to the specific stage and objectives of each project or transaction. Our assessments are developed using robust methodologies, conservative assumptions, and industry-accepted tools to deliver bankable energy yield opinions for both greenfield and operating assets. We work collaboratively with clients to review assumptions, align methodologies with project-specific data and operational statistics, and ensure that energy performance conclusions accurately reflect real-world conditions and investment considerations.
Root Cause Analysis (RCA) & Failure Investigations
Independent Root Cause Analysis (RCA) services to support asset owners, insurers, lenders, and developers in addressing major failures occurring during construction, commissioning, and operations. Our services support insurance claims, dispute resolution, and asset recovery by delivering technically robust, defensible conclusions grounded in internationally recognized standards and best practices. Leveraging our global network of specialists, we rapidly deploy multidisciplinary teams to investigate complex failures and identify practical corrective and preventive actions.
Our RCA services address a wide range of failure modes, including structural and foundation issues, tracker system and aeroelastic performance concerns, repetitive or systemic inverter failures, and commissioning or operational deficiencies. We conduct detailed structural, electrical, and mechanical analyses; evaluate compliance with applicable IEC standards; and assess operational data and site conditions to determine root causes and contributing factors. This approach enables clients to quantify impacts, support insurance and warranty claims, and implement effective mitigation strategies to protect asset value and long-term performance.
On-Site Solar Testing, Commissioning & Operational Verification
Comprehensive on-site testing and verification services support solar projects during commissioning and throughout operations. Our field teams and technical specialists perform independent testing to verify system performance, identify defects, and confirm compliance with applicable IEC standards and project specifications. These services support successful commissioning, operational acceptance, performance validation, and long-term asset reliability.
Our on-site testing services include infrared thermography for defect and hotspot detection, I-V curve testing to verify module and string performance, insulation resistance and continuity testing, and verification of inverter, tracker, and balance-of-plant functionality. We also support acceptance testing during commissioning, periodic operational inspections, and targeted testing campaigns to investigate underperformance, warranty claims, or degradation concerns. By combining field measurements with engineering analysis, we provide actionable insights that help clients protect asset value and optimize long-term performance.
