Renewables

Delivering expert solutions for complex renewable energy challenges, ensuring safe, efficient, and sustainable system design, deployment, and operation

ESi helps developers, owners, operators, manufacturers, insurers, lenders, and legal stakeholders address technical challenges across a broad range of alternative and renewable energy technologies. Our multidisciplinary engineering and testing capabilities support projects from planning and design through construction, commissioning, operation, and performance assessment.

This expertise helps clients manage technical risk, improve reliability, reduce downtime, and maintain continuity of operations. When failures, claims, or disputes arise, ESi also provides forensic investigation, root cause analysis, and technical support for insurance claims, litigation, and dispute resolution.

Alternative and renewable energy projects present interconnected technical challenges involving equipment performance, structural and mechanical integrity, electrical systems, materials, fire and thermal hazards, grid integration, energy storage, permitting, supply chains, and long-term reliability. Addressing these challenges often requires expertise that extends beyond any single engineering discipline or technology.

Our multidisciplinary teams combine engineering analysis and computational modeling with laboratory examination, field testing and instrumentation, regulatory knowledge, and decades of failure-investigation and root-cause-analysis experience. 

This foundation allows us not only to determine why complex systems fail or underperform, but also to help clients assess alternative technologies, evaluate technical and economic considerations, identify risks, and make informed decisions throughout the project lifecycle.

Frequently Asked Questions COLLAPSE

What types of renewable energy matters does ESi handle?

ESi's renewable energy consultants work across solar, wind, hydrogen, biofuel, tidal, and wave energy systems, as well as the energy storage and transportation infrastructure that supports them. Engagements span failure analysis, fire and explosion investigation, risk assessment, structural analysis, materials and corrosion evaluation, and litigation and insurance support across renewable energy asset types.

How does ESi approach a wind turbine or solar system failure investigation?

The investigation begins with examination of the failed component or system alongside available operational data, maintenance records, and design documentation. ESi applies materials analysis, structural assessment, and engineering evaluation of the specific technology involved to identify the failure mode and its origin, as well as to determine whether the failure resulted from a design deficiency, manufacturing deviation, installation error, or in-service degradation.

What distinguishes ESi from other renewable energy consulting firms?

Many renewable energy consulting firms focus on project development, performance optimization, or regulatory permitting. ESi's practice is built around forensic investigation and technical dispute resolution, applying the same rigorous analytical methods used in high-stakes litigation and insurance proceedings to renewable energy failures and incidents. Consulting team members have backgrounds in mechanical, chemical, civil and structural, electrical, and materials engineering, allowing multi-system failures to be addressed within a single engagement.

Can ESi investigate fires and explosions at renewable energy facilities?

Yes. Fires and explosions at solar installations, wind facilities, hydrogen storage systems, and battery energy storage systems are among the most technically complex incidents in the renewable energy sector. ESi combines fire investigation methodology, process engineering analysis, and materials science to reconstruct ignition and propagation sequences, assess facility design and safety systems, and produce defensible findings for insurance, litigation, and regulatory proceedings.

Does ESi provide renewable energy consulting for both active disputes and proactive risk assessment?

Yes. ESi is retained for active matters such as incident investigation, litigation support, and insurance claims, as well as for proactive engagements including process hazard analysis, failure mode and effects analysis, fitness-for-service assessment, and safety system reliability review. The same engineering rigor applies in both contexts, and proactive work is conducted with awareness that findings may need to support a future proceeding.

At what stage of a matter should ESi be engaged?

Early engagement is preferable in renewable energy matters. Physical evidence from system failures can degrade or be removed during remediation, operational data may be overwritten, and site conditions change rapidly following an incident. ESi can mobilize to preserve evidence and document conditions before that window closes. For proactive risk assessment engagements, early involvement allows ESi to identify hazards and develop mitigation strategies before incidents occur.
