Service
UL Solutions provides comprehensive renewable energy due diligence to help developers, lenders and investors mitigate risk, validate assumptions and reach financial close with confidence. Our independent team evaluates technical and commercial factors so projects are technically sound and finance-ready.
Our scopes cover energy production, technology and design, site suitability, contracts and commercial terms, environmental and permitting, CAPEX/OPEX, and construction-phase oversight, with objective reporting recognized by leading arrangers and lenders.
As your independent engineer, we deliver IE reviews that identify and mitigate project risks for debt and equity stakeholders, supporting a smooth financial close with a report framework vetted by top lenders. Explore our Wind and Solar Power Independent Engineering Services.
Whether you hold a small equity stake or a multi-asset portfolio, we tailor the scope to your risk appetite and in-house expertise, offering plant due diligence services that scale to the investment.
For onshore wind, our reviews span resource and energy assessments, turbine technology and site suitability, BoP and electrical design, contracts and O&M, with grid integration considerations and bankable reporting.
For solar, we evaluate array design and energy estimates, module/inverter technology and suitability, BoS/electrical design, warranties/O&M, and readiness for construction and operations.
Our energy due diligence assessment consulting solutions combine modeling, measurement review and field insight to quantify risk and support investment decisions.
We prepare pre‑construction and operational energy production estimates (with P‑tables), review preliminary layouts, and conduct third‑party reviews of energy estimates.
We perform technology reviews (modules, inverters, mounting structures, system integration), equipment suitability by climate, and extended lifetime assessments, plus civil/geotechnical and electrical design reviews.
We review EPC/technology supply agreements, warranties, O&M agreements, and operating assumptions to align technical performance with commercial terms.
We consider site inspections and environmental/jurisdictional factors as part of diligence. For project permitting and community impacts (e.g., noise, shadow flicker, viewshed/photo simulations), explore Permitting and Environmental Impact Assessment for Wind Farms.
During construction and commissioning, UL Solutions provides lender’s engineer monitoring and construction management, including milestone reviews, quality control oversight, performance test observation, drawdown verification and final close-out reporting. See Wind and Solar Project Construction Monitoring and Management.
UL Solutions supports projects aligned to PV safety frameworks such as IEC/UL 61730 for modules (see related expert content on our Solar advisory page).
Across wind assets, we help stakeholders navigate grid code compliance, electrical characteristics and performance through testing, inspection and certification services.
Support for equity acquisitions, portfolio reviews and risk analysis.

Leading safety science and renewable energy project advisor selected by Naturgy as independent engineer on the San Pedro Solar Farm.
Independent, third‑party technical and commercial reviews that evaluate a project’s energy potential, technology and design, site and permitting factors, contracts and financial assumptions, often packaged as an independent engineering (IE) review for financing.
It helps identify and mitigate risks, align technical performance with commercial terms, and provide bankable documentation that supports debt and equity financing.
Typical scopes include energy production estimates (pre‑construction and operational), technology/site suitability, BoP/electrical design, and reviews of contracts, warranties/O&M, environmental/permitting, CAPEX/OPEX, and construction oversight.
UL Solutions conducts site inspections and reviews preliminary layouts and environmental/jurisdictional factors; permitting studies can include noise, shadow flicker, viewshed and photo simulations to understand community impacts.
Yes. Environmental and permitting considerations are integrated, with specialized analyses to support permit applications and mitigation strategies where needed.
Engagements reference relevant safety and grid requirements. For PV, UL content highlights IEC/UL 61730 for module safety; wind services emphasize grid code compliance and performance verification.
Independent engineering (IE) provides lender‑ready, objective reports to support financial close. Technical advisory provides broader consultative support across development, design, and operations, including resource, technology and contractual reviews.
Yes, UL provides construction monitoring and management, with milestone reviews, QC oversight, test witnessing, drawdown verification, and final completion reporting.
Through investor services and technical M&A advisory, UL tailors critical review paths (energy, technology, contracts, O&M, curtailment/revenue, and portfolio risk) to help buyers and sellers identify risks and maximize value.
