Renewables Project Certification for Wind Farm Development

Comprehensive project certifications to evaluate to evaluate wind turbines for site-specific conditions, codes, and regulations.

Wind turbine farm

Certification for onshore and offshore wind farm developers

After completing the type certification process, project certification is the next step in the development of an onshore or offshore wind farm. It proves that the type-certified wind turbines and the particular substructure and foundation designs meet site-specific conditions and are in conformity with applicable local codes, official regulations and other site-specific requirements. A project certificate confirms that the structural integrity of the type-certified wind turbines should remain safe under the influence of site-specific conditions such as wind, sea, soil and electrical networks. The project certification process also evaluates the manufacturing of structural components to be installed at a specific wind farm, as well as the transportation, erection and commissioning.

Wind farm certification supports project development

Project certification is typically applied to offshore wind farm projects because they are highly complex. Offshore projects pose more challenging environmental conditions and require additional planning and logistics. For this reason, project certification is an important instrument for risk mitigation, thus may be requested by financiers, insurers and/or permitting authorities. UL Solutions has over a decade of experience in offshore wind farm certification and is able to support the project development process from early design to the design, manufacturing, transportation, installation and commissioning phases. Further risks during the operation of the offshore wind project can be reduced by an independent, third-party certification of the operations and maintenance phase.
